executeStatement() returns:

false → SQL execution failed (real error)

0 → UPDATE executed successfully, but no data changed

0 → UPDATE executed and changed data

To Reproduce

This confirms that the exception is triggered in valid and expected situations, for example when:

multiple users perform the same search query at nearly the same time, or

the same search term is executed repeatedly within the same second.
