Breaking: #67204 - DatabaseConnection::exec_SELECTgetRows() may throw exception

See Issue #67204

Description

DatabaseConnection::exec_SELECTgetRows() validates $uidIndexField parameter now. If the specified field is not present in the database result an InvalidArgumentException is thrown.

Impact

This change will affect only broken usages of DatabaseConnection::exec_SELECTgetRows() with an invalid last parameter.

It is very unlikely that existing code affected by this change, since using the method in a wrong way had the consequence that it only returned the last row from the result.

Affected Installations

Any code using the DatabaseConnection::exec_SELECTgetRows() method with $uidIndexField being set to a field name not present in the queried result set.

Migration

Fix your call to the method and correct the $uidIndexField parameter.
