Why Does `executeQuery()` Cause a Data Manipulation Exception in MySQL?

MySQL executeQuery() Data Manipulation Exception

In MySQL, when executing queries that involve data manipulation, such as INSERT, UPDATE, or DELETE statements, an error may occur if executeQuery() is used instead of executeUpdate().

Error Message:

"can not issue data manipulation statements with executeQuery()"

Explanation:

executeQuery() is used for executing SELECT statements, which retrieve data from tables without modifying them. However, when attempting to manipulate data, such as inserting, updating, or deleting records, executeUpdate() should be utilized instead.

Solution:

To resolve this issue, replace executeQuery() with executeUpdate() in the code, as shown below:

executeUpdate(query1);
executeUpdate(query2);

Note:

The executeUpdate() method returns an integer value representing the number of rows affected by the data manipulation query.
