String

Required.Specify a unique name for the Snap.

Default value: Azure Synapse SQL - Delete

String/Expression

Specify the SQL WHERE clause of the delete statement. You can specify the delete from an upstream Snap or through the Pipeline parameters. Specify a valid WHERE clause for the delete condition. If you leave this field blank, the Snap deletes all the records from the table.

Warning: Using expressions that join strings together to create SQL queries or conditions has a potential SQL injection risk and hence is unsafe. Ensure that you understand all implications and risks involved before using concatenation of strings with '=' Expression enabled.

Default value: N/A

Example:

Without using expressions

Using expressions

  • email = '[email protected]' or email = $email

  • Validate & Execute: Performs limited execution of the Snap and generates a data preview during pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during pipeline runtime.
  • Execute only: Performs full execution of the Snap during pipeline execution without generating preview data.
  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Default value: Execute only
