A process model fails when it gets to the write to database node. The error thrown is:
java.sql.BatchUpdateException: Unknown column 'X' in 'field list': com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'X' in 'field list' Data
However, when you check the table of the unknown column exists.
When data is written to the database there is a trigger that also inserts content into a secondary database. The reason that the application server throws error is because the secondary database doesn't include column X
In phpMyAdmin go to the table where the unknown column exits. Go to the Triggers tab and verify that the secondary table you are updating contains column X.
