Hi, Christian I saw the recommended tricks, but in my modest opinion they are useless or difficult to use. I think the reason for delay is in your SELECT statement, because you first select all the data from the table Customer and then insert a new record. If you optimize your select to return a small number of records the delay will be minimized. Try this: "SELECT * FROM CUSTOMER WHERE CUST_ID = 0" for example, where CUST_ID is the name of the primary key. This statement will return no records and it will be fastest & simplest way for your case.
