I want to insert data in a database table from two other tables
Whenever I run my code, it would return this particular error
An unhandled exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll - Additional information: Fatal error encountered during command execution.
which is pointed at
cmd.ExecuteNonQuery();
What would be the problem?
It's working now !!
It simply sounds like your query is timing out during execution. You could try setting cmd.CommandTimeout = 86400; or you could try creating indexes that might speed up the JOIN: CREATE INDEX bilan_siren ON bilan(siren); CREATE INDEX data_siren ON data(siren);

I solved that issue by using a old version of MySQL Net. In my case, I installed the version 6.4.4 . But you can download others versions at:
