RE: HOW TO DELETE DATA BASE TABLE

Two solution for this problem

1. Add one more column in the staging table i.e. is_processed by default that must be set to 0. When you import a file only pick rows which are having is_processed flag set to 0 and process these rows. If every validation pass put this row in the main table otherwise write in error. Once the write operation is done set the flag to 1 for that particular row.

2. Write a stored procedure where you read rows from the staging table and if it passes the validations and constraints then write to the main table otherwise write the row into the error table with a proper error message. Processed rows from the staging table can be deleted using the stored procedure by delete row syntax.

Call execute stored procedure smart service in process model to finish importing from the staging table to the main table.

Add a Query Database node to your process model and execute the SQL command "TRUNCATE" on that table.
