I am connecting to mysql and when a execute the activity Execute Query I have the net error:
Execute query : Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
It’s a query from one table without joins. I have 4 tables and I only can do a select * from one table, the others return the above error.
I would understand this error if I had inserting data but not executing a query.
