If you are encountering issues with a delete statement failing when called from SSIS to Snowflake database, there could be several possible reasons.
Here are some steps you can try to troubleshoot and resolve the issue:
Check Syntax: Verify that the syntax of the delete statement is correct and matches the expected syntax for Snowflake database. Review the Snowflake documentation or support site for guidelines on how to write and execute delete statements in Snowflake.
Check Permissions: Check that the user account being used to execute the delete statement has the necessary permissions to perform the operation. Verify that the user has delete privileges on the table being targeted in the statement.
Check Constraints: Verify that there are no constraints or dependencies on the table being targeted in the delete statement that could be causing the operation to fail. Review the table schema and any related objects to identify any potential constraints or dependencies that may be affecting the operation.
Check Connection: Verify that the connection between SSIS and Snowflake is configured correctly and that the connection string, username, and password are accurate. Test the connection using a simple query or select statement to ensure that the connection is working as expected.
Check Logs: Review the logs or error messages generated by SSIS or Snowflake to identify any specific errors or warnings that may be related to the delete statement. Use this information to troubleshoot and diagnose the issue further.
Optimize Query: If the table being targeted in the delete statement is large, consider optimizing the query to improve performance. For example, you could use a “where” clause to narrow down the scope of the delete operation or use a batched approach to delete data in smaller chunks.
If you are still having issues after trying the above steps, you may need to contact Snowflake support or Microsoft support for additional assistance. Be sure to provide them with as much information as possible about the issue, including any error messages, logs, or steps you have already taken to troubleshoot the issue.
