If multiple COPY statements set SIZE_LIMIT to 25000000 (25 MB), each would load 3 files. BINARY. Snowflake. different rows being shown. Unlike VARCHAR, the BINARY data type has no notion of Unicode characters, so the length is always measured in terms of bytes. itself. If the source data is in another format, specify the file format type and options. If this option is set to TRUE, note that a best effort is made to remove successfully loaded data files. This is the standard AWS authentication method. A control-flow statement (e.g. NVARCHAR store Unicode. The XMLGET function does not operate directly on a VARCHAR expression even if that VARCHAR contains valid XML text. If additional non-matching columns are present in the data files, the values in these columns are not loaded. Specifies whether the connector should use a proxy: true specifies that the connector should use a proxy. "PK" when column is part of table primary key. To read data from Snowflake into a Spark DataFrame: Use the read() method of the SqlContext object to construct a DataFrameReader. Spark provides only one type of timestamp, equivalent to the Scala/Java Timestamp type. If the data loading operation fails, the staging table hexadecimal), the Unicode escape sequence for a small image of a snowman, something that is not a valid escape sequence. Using External OAuth requires setting the sfToken parameter. replacement character). https://
.okta.com) or if you left the For example: Note that you can also set the autopushdown option in a Map that you pass to the options method (e.g. TIMESTAMP instead of DATETIME; The exception to this is for timestamps. filters requested by Spark to SQL. The function returns the following columns: Database that was in use at the time of the query. PRIMARY_KEY: Primary key flag. If the source table has clustering keys, then the new table has clustering keys. The default record delimiter is the new line character. Currently, negative values are always treated as seconds. This topic describes the string/text data types, including binary strings, supported in Snowflake, along with the supported formats for string constants/literals. Boolean that specifies whether to skip any BOM (byte order mark) present in an input file. If there is no existing table of that name, then the grants are copied from the source table Note that this option can include empty strings. Column reordering, column omission, and casts using a SELECT statement. column names in the source and destination tables should match. Statement end time. Also, if these options are set, they take precedence over the awsAccessKey and awsSecretKey options. From this OBJECT, you addition, any stream on a view that has this table as an underlying table, becomes stale. Replace each of these variables with the proper information for your Azure Blob Storage account. For more Default: CURRENT_WAREHOUSE. instance_number can be omitted, in which case the default value 0 is used. Source region for statements that load data from another region and/or cloud. Range: 1 to 10000. There is no requirement for your data files to have Prefer TIMESTAMP to TIME. permissions from the table being replaced with CREATE OR REPLACE (if it already exists), not from the source Note that Snowflake converts all instances of the value to NULL, regardless of the data type. BIGNUMERIC, BIGDECIMAL. Object parameter that specifies the maximum number of days for which Snowflake can extend the data retention period for the table to prevent streams on the table from becoming stale. This file format option is applied to the following actions only: Loading JSON data into separate columns using the MATCH_BY_COLUMN_NAME copy option. In addition, this command supports the following variants: CREATE TABLE AS SELECT (creates a populated table; also referred to as CTAS), CREATE TABLE USING TEMPLATE (creates a table with the column definitions derived from a set of staged files), CREATE TABLE LIKE (creates an empty copy of an existing table), CREATE TABLE CLONE (creates a clone of an existing table), ALTER TABLE , DROP TABLE , SHOW TABLES , DESCRIBE TABLE, CREATE TABLE AS SELECT (also referred to as CTAS). Defines the encoding format for binary string values in the data files. When the threshold is exceeded, the COPY operation discontinues loading files. (The name mapping is case-insensitive.). In theory, the Spark Connector The maximum number of Unicode characters that can be stored in a VARCHAR column is shown below: Between 8,388,608 (2 bytes per character) and 4,194,304 (4 bytes per character). If set to TRUE, any invalid UTF-8 sequences are silently replaced with Unicode character U+FFFD Boolean that enables parsing of octal numbers. Semi-structured Data Functions (Extraction). maximum number of characters allowed. Teradata BigQuery Notes; INTEGER: INT64: SMALLINT: INT64: BYTEINT: INT64: BIGINT: INT64: DECIMAL: NUMERIC, DECIMAL. statement, with the current timestamp when the statement was executed. CREATE OR REPLACE statements are atomic. It is used for: Performing conversion to VARCHAR in the one-argument version of TO_CHAR , TO_VARCHAR. Specify the connector options using either the option() or options() method. suspended for the new table even if Automatic Clustering was suspended for the source table. It requires a pair of awsAccessKey and awsSecretKey values. Column order does not matter. A singlebyte character string used as the escape character for unenclosed field values only. an empty string), the function returns 1.. By default, the value is FALSE, which means that Snowflake preserves the case of alphabetic characters when retrieving column names. instance_number. The option can be used when loading data into or unloading data from binary columns in a table. If tempDir is specified, you must also specify either: temporary_aws_access_key_id , temporary_aws_secret_access_key, temporary_aws_session_token. -- Stage a JSON data file in the internal stage. to prevent errors when migrating CREATE TABLE statements). A string specifying a user login name or CURRENT_USER. consisting of a name, data type, and optionally whether the column: Has any referential integrity constraints (primary key, foreign key, etc.). loading without using a staging table) You can create a map that indicates which Spark CHAR, CHARACTER. Because which specifies that Snowflake should automatically detect the format to use. A string literal, Snowflake Scripting variable, or session variable that contains a statement. Alternative syntax for ENFORCE_LENGTH with reverse logic (for compatibility with other systems). Data type with information about scale/precision or string length. Sequences have limitations; Also, if the This sample program assumes you are using version 2.2.0 (or higher) of the connector, which uses a Snowflake internal stage for storing temporary data and, therefore, does not require an S3 location for This option is commonly used to load a common group of files using multiple COPY statements. A BOM is a character code at the beginning of a data file that defines the byte order and encoding form. errors. already be staged in the cloud storage location referenced in the stage definition. Closes the cursor object. The driver discards any column in the Spark data frame that does not have a corresponding column in the We recommend using the bin/pyspark script included in the Spark distribution. sf_default: Use the default time zone for the Snowflake user who is connecting. (Note that you can choose to return the values as strings and perform the type conversions in your application. A staging table is a normal table (with a temporary name) that is created Specifies the identifier (i.e. Boolean that specifies to load all files, regardless of whether theyve been loaded previously and have not changed since they were loaded. the first column in the data frame is mapped to the first Constants (also known as literals) refer to fixed data values. Column names, types, Authenticating this way is required only in either of the following circumstances: The Snowflake Connector for Spark version is 2.1.x (or lower). Boolean that instructs the JSON parser to remove outer brackets (i.e. If no match is found, a set of NULL values for each record in the files is loaded into the table. Thus the staging table allows the original and the column names in the Snowflake table do not match the column names Azure container and the SAS (shared-access signature) for that container using For example: If no length is specified, the default is the maximum allowed length (16,777,216). Schema for the table. An escape character invokes an alternative interpretation on subsequent characters in a character sequence. | default | primary key | unique key | check | expression | comment |, |------+-----------------+--------+-------+---------+-------------+------------+-------+------------+---------|, | B | BINARY(8388608) | COLUMN | Y | NULL | N | N | NULL | NULL | NULL |, | B100 | BINARY(100) | COLUMN | Y | NULL | N | N | NULL | NULL | NULL |, | VB | BINARY(8388608) | COLUMN | Y | NULL | N | N | NULL | NULL | NULL |, ------------------------------+----------+, | 'TODAY''S SALES PROJECTIONS' | '-''''-' |, |------------------------------+----------|, | Today's sales projections | -''- |, ------------------------+---------------+, | $1 | $2 |, |------------------------+---------------|, | Tab | Hello World |, | Newline | Hello |, | | World |, | Backslash | C:\user |, | Octal | -!- |, | Hexadecimal | -!- |, | Unicode | -- |, | Not an escape sequence | z |, +------+-------------------------------------------------------+, | $1 | $2 |, |------+-------------------------------------------------------|, | row1 | a |, | | ', | | \x21 z $ |, ------+-------------------------------------------------------+. In this example, we will declare a Format Type Options (in this topic). MATCH_BY_COLUMN_NAME copy option. Deflate-compressed files (with zlib header, RFC1950). By default, when a target table in Snowflake is overwritten, the schema of The maximum length of an OBJECT is 16 MB. Before using External OAuth and the Spark Connector to authenticate to Snowflake, configure an External OAuth security integration for one of the supported External OAuth authorization servers or an External OAuth custom client. The default value is SNOWFLAKE.. For more information on authentication, see Managing/Using Federated Authentication and OAuth with Clients, Drivers, and Connectors.. password. However, there are forms of filters that the Spark infrastructure today does not pass to the Snowflake connector. America/New_York), if valid. . Error code, if the query returned an error, Error message, if the query returned an error. Otherwise, the default value is off. If the statement is replacing an existing table of the same name, then the grants are copied from the table When creating a table with a masking policy on one or more table columns, or a row access policy added to the table, use the communications between the Spark master and Spark workers are not secure, the credentials could be read by an The ORDER BY, LIMIT,FETCH,TOP keywords in SELECT statements are also not supported. Default (and maximum) is 16,777,216 bytes. path is an optional case-sensitive path for files in the cloud storage location (i.e. When comparing values in a collated column, Release version in the format of major_release.minor_release.patch_release. Dropping the default column value from any clone of the table is also prohibited. Load semi-structured data into columns in the target table that match corresponding columns represented in the data. When Snowflake displays BINARY data values, Snowflake often represents each If the format of the input parameter is a string that contains an integer: After the string is converted to an integer, the integer is treated as a number of seconds, milliseconds, microseconds, or nanoseconds after the start of the Unix To start, complete the initial configuration for key pair authentication as shown in Key Pair Authentication & Key Pair Rotation. If a length is not specified, the default is the maximum length. If the string contains contains many single quotes, backslashes, or other special characters, you can use a Setting sfTimezone to snowflake for the connector and setting the TIMEZONE session These are temporary AWS credentials that allow access to the location As an example, the following table shows how the maximum number of characters can vary for a VARCHAR(16777216) column, depending Time (in milliseconds) spent in the warehouse queue, waiting for compute resources in the warehouse to be repaired. sequence of characters '\z' is interpreted as 'z'. data_type. For example, assuming FIELD_DELIMITER = '|' and FIELD_OPTIONALLY_ENCLOSED_BY = '"': (the brackets in this example are not loaded; they are used to demarcate the beginning and end of the loaded strings). It is only necessary to include one of these two A statement can be any of the following: A single SQL statement. Specifies the list of hosts that the connector should connect to directly, bypassing the proxy server. Password for the user. connector, Snowflake strongly recommends upgrading to the latest version. The data type of the returned value is DATE. namespace is the database and/or schema in which the internal or external stage resides, in the form of database_name. context functions: For the list of reserved keywords, see Reserved & Limited Keywords. By default, Automatic Clustering is not suspended for the new table even if Automatic Clustering is suspended for the Boolean that specifies whether to truncate text strings that exceed the target column length: If TRUE, the COPY statement produces an error if a loaded string exceeds the target column length. namespace is the database and/or schema in which the external stage resides, in the form of database_name. Similar to the previous example, but loads semi-structured data from a file in the Parquet format. If set to FALSE, the load operation produces an error when invalid UTF-8 character encoding is detected. By default, wildcard character matching is disabled. The simple expression cannot contain references to: UDFs written in languages other than SQL (e.g. The maximum size for each file is set using the MAX_FILE_SIZE copy option. All the requirements for table identifiers also apply to column identifiers. By default, wildcard character matching is disabled. to shifting the letters in column names to uppercase, unless the column The possible values of this parameter are: If this parameter is on, the original schema of the target table is kept. Recreating or swapping a table drops its change data. These columns must support NULL values. This is the standard Azure Blob storage authentication method. A control-flow statement (e.g. string_literal. Specifies which occurrence of the pattern to replace. The default record delimiter is the new line character. files have names that begin with a As file format options specified for a named file format or stage object. The OBJECT must contain When clustering keys are specified in a CTAS statement: Column definitions are required and must be explicitly specified in the statement. FALSE does not enable change tracking on the table. window to ask the user for credentials. Set the AUTOINCREMENT or IDENTITY default value for a number column. A string specifying a table name. If the XML contains multiple instances of tag_name, then use instance_number to specify which instance to retrieve. If set to on (default), a COPY command automatically truncates text strings that exceed the target column length. TEXT When writing a table from Snowflake to Spark, the Spark connector defaults STRING. This behavior might change in the future. To connect, you can save the Python example to a file (i.e. When unloading data, compresses the data file using the specified compression algorithm. errors could result in delays and wasted credits. For a detailed description of this object-level parameter, as well as more information about object parameters, see Parameters. As such, when transferring data between Spark and Snowflake, Snowflake recommends using the following approaches to preserve time correctly, relative to time zones: Use only the TIMESTAMP_LTZ data type in Snowflake. column name mapping is case-insensitive, it is not possible to determine the correct mapping from the data frame If the USING clause is omitted, Snowflake treats the conditional masking policy as a normal it is equivalent to SELECT * FROM db_table). Specifies the column identifier (i.e. Note that you can also set the autopushdown option in a Dictionary that you pass to the options method a number of seconds. TRY_TO_DECIMAL, TRY_TO_NUMBER, TRY_TO_NUMERIC. In some cases, you might need to specify a string constant that contains: Backslash characters (e.g. a regular expression), you must escape the backslash with a second backslash. If a TABLE object type is specified, and the object specified by name is a view, the function returns the DDL for the view and vice-versa.. Spark DataframeReader class. This simplifies the code and reduces the chance of errors. 'SKIP_FILE_num%', all records up to the record that contains the parsing error are loaded, but the remainder of the records This file format option is applied to the following actions only when loading Orc data into separate columns using the The expression from which to extract the element. You can use the ESCAPE character to interpret instances of the FIELD_DELIMITER or RECORD_DELIMITER characters in the data as literals. Default: 100. Character used to enclose strings. ), for the object type in the schema. To include a single quote or other special characters (e.g. see Understanding & Using Time Travel and Working with Temporary and Transient Tables. unbound: the link is declared as a collection element for a 1-N cardinality (by default) integrity: define by default (can be forced with the revIntegrity attribute in the link definition on the source schema). in sfOptions in the example above). For more information about entering and displaying BINARY data, see: Applies only to QUERY_HISTORY_BY_WAREHOUSE. Required only when applying a masking policy, row access policy, object tags, or any combination of these governance features when creating tables. TIMESTAMP instead of DATETIME; The exception to this is for timestamps. variable. exchange. files in your CLASSPATH environment variable. The time zone in Snowflake is set to Europe/Warsaw, which can happen by either: Setting sfTimezone to Europe/Warsaw for the connector. The @ property contains the nested tag name and the $ property Depending on the file format type specified (STAGE_FILE_FORMAT = ( TYPE = )), you can include one or more of the following format-specific options (separated The following example loads data from columns 1, 2, 6, and 7 of a staged CSV file: This sample script assumes you are using version 2.2.0 (or higher) of the connector, which uses a Snowflake internal stage for storing temporary data and, therefore, does not require an S3 location for to adding double quotes around any column name that contains any characters To avoid this issue, set the value to NONE. Although TO_DATE accepts a TIMESTAMP value, it does not accept a TIMESTAMP inside a VARIANT. If you wish to authenticate with OAuth, see Using External OAuth (in this topic). This parameter applies only when the column_mapping parameter is set to name. Specifies to retain the access privileges from the original table when a new table is created using any of the following CREATE TABLE variants: The parameter copies all privileges, except OWNERSHIP, from the existing table to the new table. To ensure a compile-time check of the class name, Snowflake highly recommends defining a variable for the class name. means abort if an error is hit. Usage Notes. Heres an example Python script that performs a simple SQL query. Target region for statements that unload data to another region and/or cloud. To take advantage of error checking, set CSV as the format type (default value). If you use a session variable, the length of the statement must not exceed data file. The default virtual warehouse to use for the session after connecting. option as the character encoding for your data files to ensure the character is interpreted correctly. Copy options are used for loading data into and unloading data out of tables. The default value is 100. Example 2. For safety, Snowflake If a match is found, the values in the data files are loaded into the column or columns. NULLABLE: Nullable flag. When unloading data, files are compressed using the Snappy algorithm by default. | default | primary key | unique key | check | expression | comment |, |------+--------------+--------+-------+---------+-------------+------------+-------+------------+------------------|, | COL1 | NUMBER(38,0) | COLUMN | Y | NULL | N | N | NULL | NULL | a column comment |, ------+--------------+--------+-------+---------+-------------+------------+-------+------------+---------+, | name | type | kind | null? For more information about the impact of setting this option, see Working with Timestamps and Time Zones (in this topic). If no length is specified, the default is the maximum allowed length (16,777,216). can extract the tag name, the tags attribute values, and the contents of the element (including nested tags) is useful if the user does not have permission to create a table. The COPY operation verifies that at least one column in the target table matches a column represented in the data files. The SHOW GRANTS output for the replacement table lists the grantee for the copied privileges as the role that executed the CREATE TABLE default_varchar_size. E.g. The runQuery method returns only TRUE or FALSE. */, Working with Temporary and Transient Tables, Storage Costs for Time Travel and Fail-safe, with reverse logic (for compatibility with other systems), ---------------------------------+---------+---------------+-------------+-------+---------+------------+------+-------+--------------+----------------+, | created_on | name | database_name | schema_name | kind | comment | cluster_by | rows | bytes | owner | retention_time |, |---------------------------------+---------+---------------+-------------+-------+---------+------------+------+-------+--------------+----------------|, | Mon, 11 Sep 2017 16:32:28 -0700 | MYTABLE | TESTDB | PUBLIC | TABLE | | | 1 | 1024 | ACCOUNTADMIN | 1 |, --------+--------------+--------+-------+---------+-------------+------------+-------+------------+---------+, | name | type | kind | null?
