Table Visual unable to load data despite having fewer rows.

Hi SaiK ,

This can be caused by several different things mainly the queries that you are sending to the engine that may be reaching the limit as Bibiano_Geraldo said. Without additional information is difficult to understand what is happenning.

One option can be to remove fields from the 2nd table until you get a result that way you may understand what is happening and try to focus on that specific values or set of values.

Without any specific details is difficult to pin point the root causes.
