In my old design, I put all the tables in the data environment.
After 1 year, the form is loaded terribly slow .
I found that the invoice's table size is over 20M and other around 6M
Now, i need to remove all the tables and I don't know how to do .
Some said i can open table as I need .
However, I don't know How's the coding .(How can i open the table and close the tables?)
Can anyone be kind to teach me ??
Thx a lot
