COPY INTO <table> Command Examples
For examples of transformations to load data, see .
File upload from an internal stage
Loading files from a named external stage
Upload files directly from an external storage location
Load with pattern matching
Loading JSON data into a VARIANT column
reload files
Clean up files after upload
Validation of prepared files
Using the COPY INTO <table> command
When loading into a table from the same level as the table, the FROM clause is not required and can be omitted.
When transforming data on the fly (that is, using a query as a source for the COPY command):
File data selection is only supported for named stages (internal or external) and user stages. It does not support table levels.
CSV and semi-structured file types are supported; but also when uploading semi-structured data (eg JSON), you should set CSV as the file format type (default). You can use the appropriate file format (eg 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.
Also, set the file format option
FIELD_DELIMITER = NONE.To transform JSON data during an upload, you must structure your data files in the standard format ("newline-delimited JSON"); Otherwise, the following error may occur:
Error Analyze JSON: further Era as document they o VerbotenThe DISTINCT keyword in SELECT statements is not fully supported. Specifying the keyword can result in inconsistent or unexpected behavior of the ON_ERROR copy option.
Upload from Google Cloud Storage only:The list of objects returned to an external stage may contain one or more "blob directories"; essentially paths that end in a slash (
/), For example.:LIST @my_gcs_stage;+------------------------+------+--- --------------- ----------------------------+------------------ --------- -----+| name | size | md5 | last_modified ||---------------------------------------+------+-- - -------------+---------------- --------------|| my_gcs_stage/load/ | 12 | 12348f18bcb35e7b6b628ca12345678c | 11 de septiembre de 2019 16:57:43 GMT || my_gcs_stage/load/data_0_0_0.csv.gz | 147 | 9765daba007a643bdff4eae10d43218y | 11 de septiembre de 2019 18:13:07 GMT |+------------------------+------+--- --------------- ----------------------------+------------------ --------- -----+
(Video) 1. Truncate Table in Snowflake| SNOWFLAKE SQL Command Reference| Snowflake Database| DML| VCKLY TechThese blobs are listed by creating directories in the Google Cloud Platform console instead of using another tool provided by Google.
COPY statements that reference a level can fail if the list of objects contains directory blobs. To avoid errors, we recommend using file pattern matching to identify files to include (that is, the PATTERN clause) when a stage's file list contains directory blobs. For an example, see (in this topic). Alternatively, set ON_ERROR = SKIP_FILE in the COPY statement.
When referring to a file format in the current namespace (the active database and schema in the current user's session), you can omit the single quotes around the format identifier.
STORAGE_INTEGRATION,CREDENTIALS, zCRYPTOGRAPHYApplies only when uploading directly from a private/protected location:If you are uploading from a public bucket, secure access is not required.
When you load from a named external stage, the stage provides all the credentials needed to access the repository.
If errors occur while executing the COPY command, after the command completes, you can validate the files that caused the errors with the spreadsheet function.
supervision
The VALIDATE function only returns the output for the COPY commands used to perform the standard data load; COPY commands that perform transformations during data loading (for example, loading a subset of data columns or reordering data columns) are not supported.
Unless specifically stated by you
FORTALEZA = TRUEAs one of the copy options, the command ignores any prepared data files that have already been loaded into the table. To reload the data, you must specifyFORTALEZA = TRUEor modify the file and try again, which will generate a new checksum.The COPY command does not validate data type conversions for Parquet files.
