Cannot issue data manipulation statements with executeQuery()


java mysql jdbc

To manipulate data you actually need executeUpdate() rather than executeQuery().

Here's an extract from the executeUpdate() javadoc which is already an answer at its own:

Executes the given SQL statement, which may be an INSERT, UPDATE, or DELETE statement or an SQL statement that returns nothing, such as an SQL DDL statement.

java mysql jdbc

When executing DML statement , you should use executeUpdate/execute rather than executeQuery.

Here is a brief comparison :

executeQueryVSexecuteUpdateVSexecute

java mysql jdbc

If you're using spring boot, just add an @Modifying annotation. 

@Modifying@Query(value = "UPDATE user SET middleName = 'Mudd' WHERE id = 1", nativeQuery = true)void updateMiddleName();
