Have to make access to a lot of tables. On a lot of tables I have to select the same ranges. ...
What should I do?
Join the tables to one query?
Isn't this slowing down the program?
Or is the combined tables query as fast as the different tables ranged? What about the memmory?
How much memmory do you need when you connect a TTable to a database table. And what if you add two TTables to one database table. What about the speed?
What if you don't select all fields in the fieldeditor? Does this reduce the needed memmory and icreases speed. Or does this do nothing?
Help! Need some advice.
