Hello,

Using PB 2017 R3, PostgreSQL 11

Need to rollback on database disconnect command.

Updating a sequence of dw within a database transactions.  If, in the middle of the update, some error erupts my application gets closed after disconnecting the database.   And this disconnection seems to commit the data, instead of rollback.   

This commit occurs only when there is an error in program, does not happen when database returns any error. My pseudo code is:

*********************************************

sqlca.autocommit(False)
ll_rc = dw_1.update(true, false)
If ll_rc = 1 Then
//   Some settings
      dw_2.SetItem(ll_row, 'field', ll_field)
      dw_2.SetItem(ll_row, 'field2', ls_field)
       ll_rc = dw_2.update(True, false)
End if

Sqlca.autocommit(True)

************************************************

If some typo errors in SetItem statement, system error event is called which disconnects the database and closes the application.   And dw_1. data gets updated.

Is there any settings that I could avoid this database update ?

Happiness Always
