The name of a custom stage to use during bulk write operations.

Data Type

string

Default Value

""

Remarks

The name of a custom stage to use during bulk write operations. This can be an internal or external stage. If the stage is external, the AWS or Azure credentials must be provided as well via the ExternalStageAWSAccessKey/ExternalStageAWSSecretKey or ExternalStageAzureAccessKey properties.

When the CustomStage property is left unspecified, the driver will generate a temporay stage automatically during the upload process and delete it after the upload is complete.

To avoid parsing errors with the generated CSV, you should include the FIELD_OPTIONALLY_ENCLOSED_BY parameter on the stage definition and set it to the double quote character. Otherwise, you may face parsing issues if you have string values that contain special characters in CSV (commas, double quotes, etc.). For example:

CREATE STAGE "TEST_STAGE_CDATA" FILE_FORMAT = ( FIELD_OPTIONALLY_ENCLOSED_BY='\"' )
