Trouble executing a MySQL delete statement in Java

Question

I am trying to have this code run and delete a certain record in a MySQL database but I get this error:

SQLException: Can not issue data manipulation stateme         


        

Answer 1

Change

ResultSet rs = statement.executeQuery("DELETE FROM content_resource WHERE RESOURCE_ID LIKE '%Hollow%'");

To

int deletedRows = statement.executeUpdate("DELETE FROM content_resource WHERE RESOURCE_ID LIKE '%Hollow%'");

As others have said, executeQuery() should be used for statements that return data, typically a select statement. For insert / update / delete statements you should use executeUpdate() instead.

Answer 2

Use execute instead of executeQuery.

As far as I know, executeQuery must be used if you are executing a query that returns a resultset (select for example).

Answer 3

To execute a DML statement (insert, create or delete), you must use executeUpdate(). Not executeQuery().

Answer 4

You use executeUpdate() for that instead.

executeQuery() is only for statements that return data. executeUpdate is for ones that won't return date (update, insert, delete, and I believe things like adding/dropping tables, constraints, triggers, and the like as well).

Answer 5

Use executeUpdate instead of executeQuery. JDBC is bummed because the delete statement does not return a record set, as executeQuery expects.

Answer 6

Ensure that you have set permissions for DELETE statements. Certain users will have certain commands disallowed for security purposes.
