OpenESQL issues


I'm getting odd behaviour testing OpenESQL (VC2.3.2, VS2015, Windows10). I've previously only used native MF files but have used MySQL extensively with PHP online.

My tests act as though MF DEBUG runs in it's own world. It doesn't actually update my MySQL database?

I have a 3-col 'vatrates' table. Cols: id, startDate and vatRate. It has one row of data.

My prog below inserts two more rows. No error is reported, Hence 3 rows.

Next I run select/fetch - this gets the three rows, the old row and two new ones.

Lastly the prog deletes a row - this seems to work and if I re-step through the select/fetch it returns two rows.

HOWEVER, at any point during the above and after stop run... if i view the table in MySQL Workbench I only see the original row. If I re-run my prog it starts again as though only the original one row is there.

Any ideas what is going on here? Program follows below....

Thanks, Linden
