DB Connect not working with rising column

[ibabansk]

Good day! The databases are duplicated every time, and when using the "Rising Column" errors, various errors are displayed. Highly
I ask for help, I can not solve it either as a problem with the database. At the same time, half of the requests work if you work through a thick client.

Hi
It seems to be a time out issue. Basically you are looking too many rows from table to get those within given timeout.
You should use numeric column if possible as a rising column with increasing values (no duplicates) instead of timestamp etc. (that can be duplicate!). Also if there are lot of rows then add index for that column.
