Hi,

Sorry for creating too many threads about somewhat of the same problem/solution.

I have been thinking and analyzing my code, none stop, every waking hour. And I just realized why I am not seeing the results I expect.
In a nutshell:
The application method CONN_HANDLE_ACCESS fires to check if SQLEXE() works. The code is literally like this:
IF SQLEXEC( oApp.conn_handle, "") < 0 
But the above only tests if an empty string can be executed.

Often times, after the above code, the program fails when attempting to SQL Select some records from the SQL Server.

So, I am thinking that the code of testing SQLEXEC() against an empty string, should be changed to testing SQLEXEC() against something in the SQL Server. Because, if the connection to the SQL Server is broken, the SQLEXEC() can still successfully work on an empty string. Right?

If the above logic is correct, how do I change the test of SQLEXEC() NOT against an empty string but against something in the SQL Server?

Any suggestions or input? TIA
