RE: How can I speed up the copying of data using DDM and field selection.

<Steve>
I'm not using SQL against a DDMF...use SQL against the source file...this process is running on the source machine, not the target. So the SQL will work against the source file.

I'll be more clear.

Use SQL to create an SQL cursor against the source file on the source machine.

Read the cursor and write the selected row to the DDMF using the HLL program's IO functions (not SQL).

When the row is written to the local DDMF, the data will go to the target machine's file.

Creating a DDM file on a production machine, creating and running a programm on a production machine, transferring data to a test machine - this might hardly be sox compliant.
