For details, see Additional Cloud Provider Parameters (in this topic). If set to FALSE, Snowflake attempts to cast an empty field to the corresponding column type. Specifies the escape character for enclosed fields. Optionally specifies an explicit list of table columns (separated by commas) into which you want to insert data: The first column consumes the values produced from the first field/column extracted from the loaded files. Boolean that specifies whether to remove white space from fields. To specify more than one string, enclose the list of strings in parentheses and use commas to separate each value. Single character string used as the escape character for field values. You must explicitly include a separator (/) either at the end of the URL in the stage The escape character can also be used to escape instances of itself in the data. We recommend that you list staged files periodically (using LIST) and manually remove successfully loaded files, if any exist. Additional parameters might be required. For loading data from delimited files (CSV, TSV, etc. For more information about load status uncertainty, see Loading Older Files. For example, suppose a set of files in a stage path were each 10 MB in size. table function. If set to TRUE, Snowflake replaces invalid UTF-8 characters with the Unicode replacement character. The initial set of data was loaded into the table more than 64 days earlier. using a query as the source for the COPY command): Selecting data from files is supported only by named stages (internal or external) and user stages. For use in ad hoc COPY statements (statements that do not reference a named external stage). Alternatively, set ON_ERROR = SKIP_FILE in the COPY statement. * is interpreted as “zero or more occurrences of any character.” The square brackets escape the period character (.) ), as well as unloading data, UTF-8 is the only supported character set. Note that this function also does not support COPY statements that transform data during a load.

Data files to load have not been compressed. The dataset consists of two main file types: Checkouts and the Library Connection Inventory. The load status is unknown if all of the following conditions are true: The file’s LAST_MODIFIED date (i.e. Required Parameters¶ [namespace.] Files are in the stage for the specified table. The master key must be a 128-bit or 256-bit key in Base64-encoded form. Step 3. The SELECT statement used for transformations does not support all functions. */, /* Create an internal stage that references the JSON file format. The COPY command allows permanent (aka “long-term”) credentials to be used; however, for security reasons, do not use permanent PATTERN applies pattern matching to load data from all files that match the regular expression .*employees0[1-5].csv.gz. If set to TRUE, any invalid UTF-8 sequences are silently replaced with the Unicode character U+FFFD Boolean that enables parsing of octal numbers. (i.e. For more details, see Note that, when a MASTER_KEY Snowflake External Tables. COPY commands contain complex syntax and sensitive information, such as credentials. that precedes a file extension. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). The COPY operation loads the semi-structured data into a variant column or, if a query is included in the COPY statement, transforms the data. schema_name or schema_name.It is optional if a database and schema are currently in use within the user session; otherwise, it is required.. FROM Boolean that specifies whether to remove leading and trailing white space from strings. Applied only when loading JSON data into separate columns (i.e. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). Snowflake replaces these strings in the data load source with SQL NULL. Pre-requisite. Note that any space within the quotes is preserved. sensitive information being inadvertently exposed. Relative path modifiers such as /./ and /../ are interpreted literally because “paths” are literal prefixes for a name. Credentials are generated by Azure. Applied only when loading ORC data into separate columns (i.e. The COPY operation verifies that at least one column in the target table matches a column represented in the data files. NULL, which assumes the ESCAPE_UNENCLOSED_FIELD value is \\ (default)). The command returns the following columns: Name of source file and relative path to the file, Status: loaded, load failed or partially loaded, Number of rows parsed from the source file, Number of rows loaded from the source file, If the number of errors reaches this limit, then abort. An external location like Amazon cloud, GCS, or Microsoft Azure. Sometimes you need to duplicate a table. Applied only when loading ORC data into separate columns (i.e. The COPY command, the default load method, performs a bulk synchronous load to Snowflake, treating all records as INSERTS. First use “COPY INTO” statement, which copies the table into the Snowflake internal stage, external stage or external location. This copy option is supported for the following data formats: For a column to match, the following criteria must be true: The column represented in the data must have the exact same name as the column in the table. Accepts common escape sequences, octal values (prefixed by \\), or hex values (prefixed by 0x). Snowflake offers two types of COPY commands: COPY INTO : This will copy the data from an existing table to locations that can be: An internal stage table. Currently, this copy option supports CSV data only. String used to convert to and from SQL NULL. Also, data loading transformation only supports selecting data from user stages and named stages (internal or external). Creating a new, populated table in a cloned schema. Required only for loading from an external private/protected cloud storage location; not required for public buckets/containers. information as it will appear when loaded into the table. Specifies the client-side master key used to decrypt files. It is provided for compatibility with other databases. Specifies the name of the storage integration used to delegate authentication responsibility for external cloud storage to a Snowflake identity and access management (IAM) entity. */, /* Copy the JSON data into the target table. You can use is used. Specifies the internal or external location where the files containing data to be loaded are staged: Files are in the specified named internal stage. If a value is not specified or is AUTO, the value for the TIME_INPUT_FORMAT session parameter is used. By default, the command stops loading data If the table already existing, you can replace it by providing the REPLACE clause. field (i.e. Accepts common escape sequences, octal values, or hex values. As mentioned earlier, external tables access the files stored in external stage area such as Amazon S3, GCP bucket, or Azure blob storage.

The delimiter is limited to a maximum of 20 characters. The copy option performs a one-to-one character replacement. The list must match the sequence of columns in the target table. The External tables are commonly used to build the data lake where you access the raw data which is stored in the form of file and perform join with existing tables. That is, each COPY operation would discontinue after the SIZE_LIMIT threshold was exceeded. String that specifies whether to load semi-structured data into columns in the target table that match corresponding columns represented in the data. Boolean that specifies whether to generate a parsing error if the number of delimited columns (i.e. Note that the load operation is not aborted if the data file cannot be found (e.g. for both parsing and transformation errors. Boolean that specifies whether to interpret columns with no defined logical data type as UTF-8 text. The column in the table must have a data type that is compatible with the values in the column represented in the data. Boolean that specifies whether to replace invalid UTF-8 characters with the Unicode replacement character (�). In the following example, the first command loads the specified files and the second command forces the same files to be loaded again (producing duplicate rows), even though the contents of the files have not changed: Load files from a table’s stage into the table and purge files after loading. For example, for fields delimited by the thorn (Þ) character, specify the octal (\\336) or hex (0xDE) value. STORAGE_INTEGRATION, CREDENTIALS, and ENCRYPTION only apply if you are loading directly from a private/protected storage location: If you are loading from a public bucket, secure access is not required. Applied only when loading Parquet data into separate columns (i.e. set of valid temporary credentials. Note that the actual field/column order in the data files can be different from the column order in the target table. Specifies the name of the table into which data is loaded. If set to FALSE, the load operation produces an error when invalid UTF-8 character encoding is detected.

Applied only when loading Avro data into separate columns (i.e. If you encounter errors while running the COPY command, after the command completes, you can validate the files that produced the errors using the VALIDATE Snowflake data needs to be pulled through a Snowflake Stage – whether an internal one or a customer cloud provided one such as an AWS S3 bucket or Microsoft Azure Blob storage. This file format option is currently a Preview Feature. The master key must be a 128-bit or 256-bit key in Base64-encoded form. To specify more than one string, enclose the list of strings in parentheses and use commas to separate each value. The COPY command skips the first line in the data files: COPY INTO mytable FILE_FORMAT = (TYPE = CSV FIELD_DELIMITER = '|' SKIP_HEADER = 1); Note that when copying data from files in a table stage, the FROM clause can be omitted because Snowflake automatically checks for files in the table stage. For example, when set to TRUE: Boolean that specifies whether UTF-8 encoding errors produce error conditions. String (constant) that specifies the current compression algorithm for the data files to be loaded. When invalid UTF-8 character encoding is detected, the COPY command produces an error. For example: In these COPY statements, Snowflake looks for a file literally named ./../a.csv in the external location. The files must already have been staged in either the Snowflake internal location or external location specified in In addition, set the file format option FIELD_DELIMITER = NONE. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). For example, if your external database software encloses fields in quotes, but inserts a leading space, Snowflake reads the leading space rather than the opening quotation character as the beginning of the credentials in COPY commands. One or more singlebyte or multibyte characters that separate fields in an input file. An escape character invokes an alternative interpretation on subsequent characters in a character sequence. The load operation should succeed if the service account has sufficient permissions to decrypt data in the bucket. After a designated period of time, temporary credentials expire and can no longer be used. A table can have multiple columns, with each column definition consisting of a name, data type, and optionally whether the column: Requires a value (NOT NULL). Snowflake connector utilizes Snowflake’s COPY into [table] command to achieve the best performance. You can also download the data and see some samples here. Specifies the encryption type used. Below URL takes you to the Snowflake download index page, navigate to the OS you are using and download the binary and install. Unless you explicitly specify FORCE = TRUE as one of the copy options, the command ignores staged data files that were already loaded into the table. Default: New line character. String used to convert to and from SQL NULL. JSON), but any error in the transformation will stop the COPY operation, even if you set the ON_ERROR option to continue or skip the file. Specifying the keyword can lead to inconsistent or unexpected ON_ERROR copy option behavior. Defines the format of time string values in the data files. Note that the difference between the ROWS_PARSED and ROWS_LOADED column values represents the number of rows that include detected errors. the PATTERN clause) when the file list for a stage includes directory blobs. For use in ad hoc COPY statements (statements that do not reference a named external stage). NULL, which assumes the ESCAPE_UNENCLOSED_FIELD value is \\). Boolean that specifies whether the XML parser strips out the outer XML element, exposing 2nd level elements as separate documents. For use in ad hoc COPY statements (statements that do not reference a named external stage). Note that this value is ignored for data loading. String (constant) that defines the encoding format for binary input or output. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). Abort the load operation if any error is encountered in a data file. There is no requirement for your data files For more details, see CREATE STORAGE INTEGRATION. If a value is not specified or is AUTO, the value for the TIME_INPUT_FORMAT parameter is used. is TRUE, Snowflake validates the UTF-8 character encoding in string column data after it is converted from its original character encoding. The COPY command does not validate data type conversions for Parquet files. Has a default value. You can export the Snowflake schema in different ways, you can use COPY command, or Snowsql command options. Prerequisites. to the corresponding columns in the table. “replacement character”). sequence as their default value. For more details about the PUT and COPY commands, see DML - Loading and Unloading in the SQL Reference. Alternative syntax for ENFORCE_LENGTH with reverse logic (for compatibility with other systems). Danish, Dutch, English, French, German, Italian, Norwegian, Portuguese, Swedish. Use “GET” statement to download the file from the internal stage. FORMAT_NAME and TYPE are mutually exclusive; specifying both in the same COPY command might result in unexpected behavior. Defines the format of date string values in the data files. It is optional When the threshold is exceeded, the COPY operation discontinues loading files. It is not supported by table stages. Number (> 0) that specifies the maximum size (in bytes) of data to be loaded for a given COPY statement. However, Snowflake doesn’t insert a separator implicitly between the path and file names. files have names that begin with a common string) that limits the set of files to load. Files can be staged using the PUT command. parameters in a COPY statement to produce the desired output. You can specify one or more of the following copy options (separated by blank spaces, commas, or new lines): String (constant) that specifies the action to perform when an error is encountered while loading data from a file: Continue loading the file. It is provided for compatibility with other databases. Raw Deflate-compressed files (without header, RFC1951). String used to convert to and from SQL NULL. For information, see the Client-side encryption information in the Microsoft Azure documentation. The exporting tables to local system is one of the common requirements. Applied only when loading Parquet data into separate columns (i.e. Applied only when loading Avro data into separate columns (i.e. For an example, see Loading Using Pattern Matching (in this topic). For a complete list of the supported functions and more details about data loading transformations, including examples, see the usage notes in Transforming Data During a Load. COPY INTO ¶ Unloads data from a table (or query) into one or more files in one of the following locations: Named internal stage (or table/user stage). Boolean that specifies to load all files, regardless of whether they’ve been loaded previously and have not changed since they were loaded. Specifies the format of the data files to load: Specifies an existing named file format to use for loading data into the table. Finally, copy staged files to the Snowflake table; Let us go through these steps in detail. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). Snowflake Snowflake SnowSQL provides CREATE TABLE as SELECT (also referred to as CTAS) statement to create a new table by copy or duplicate the existing table or based on the result of the SELECT query. COPY command produces an error. Applied only when loading XML data into separate columns (i.e. At the time of writing, the full list of supported is contained in the table below. Defines the encoding format for binary string values in the data files. options, for the data files. Related: Unload Snowflake table into JSON file. Load files from the user’s personal stage into a table: Load files from a named external stage that you created previously using the CREATE STAGE command. Applied only when loading ORC data into separate columns (i.e. if a database and schema are currently in use within the user session; otherwise, it is required. If the purge operation fails for any reason, no error is returned currently. SELECT list), where: Specifies the positional number of the field/column (in the file) that contains the data to be loaded (1 for the first field, 2 for the second field, etc.). Possible values are: AWS_CSE: Client-side encryption (requires a MASTER_KEY value). If the file is successfully loaded: If the input file contains records with more fields than columns in the table, the matching fields are loaded in order of occurrence in the file and the remaining fields are not loaded. Loading from an AWS S3 bucket is currently the most common way to bring data into Snowflake. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). String that defines the format of timestamp values in the data files to be loaded. ; Second, using COPY INTO command, load the file from the internal stage to the Snowflake table. Paths are alternatively called prefixes or folders by different cloud storage services. In this tip, we’ve shown how you can copy data from Azure Blob storage to a table in a Snowflake database and vice versa using Azure Data Factory. By default, COPY does not purge loaded files from the location. ), UTF-8 is the default. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). If set to TRUE, Snowflake validates UTF-8 character encoding in string column data. An escape character invokes an alternative interpretation on subsequent characters in a character sequence. The command used for this is: Spool JSON, XML, and Avro data only. To specify more than one string, enclose the list of strings in parentheses and use commas to separate each value. Loading from Google Cloud Storage only: The list of objects returned for an external stage might include one or more “directory blobs”; essentially, paths that end in a forward slash character (/), e.g. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). definition or at the beginning of each file name specified in this parameter. The URI string for an external location (Amazon S3, Google Cloud Storage, or Microsoft Azure) must be enclosed in single quotes; however, you can enclose any string in single quotes, which when a MASTER_KEY value is provided, TYPE is not required). See the COPY INTO topic and the other data loading tutorials for additional error checking and validation instructions. using the MATCH_BY_COLUMN_NAME copy option or a COPY transformation). Specifies the path and element name of a repeating value in the data file (applies only to semi-structured data files). the command. the quotation marks are interpreted as part of the string of field data). Note that this is just for illustration purposes; none of the files in this tutorial contain errors. The second column consumes the values produced from the second field/column extracted from the loaded files. when the first error is encountered; however, we’ve instructed it to skip any file containing an error and move on to loading Use the PUT command to copy the local file(s) into the Snowflake staging area for the table. For example, string, number, and Boolean values can all be loaded into a variant column. Semi-structured data files (JSON, Avro, ORC, Parquet, or XML) currently do not support the same behavior semantics as structured data files for the following ON_ERROR values: CONTINUE, SKIP_FILE_num, or SKIP_FILE_num% due to the design of those formats. Files are in the specified external location (Azure container). Additional parameters might be required.
