Dynamically Enable SQL Statements
(1) If the checkbox is set, a variable selected here controls the execution of SQL statements. If no variable is selected, the setting of the checkbox applies. If the selected variable has the value true, the SQL statements are executed. Note: The variable is evaluated after the mapping. In the logging for phase 4, it will be stated whether the SQL execution was activated/deactivated due to the variable.
So the SQL statements in phase 4 will only be executed if
at least one destination structure node has a database alias and an SQL table assigned (see section Phase 4 - SQL Execution),
at least one field under this node has a SQL column name assigned (see section Phase 4 - SQL Execution) and
condition (1) is met (see section Phase 2 (GUI)).
