无法使用JDBC插入表中

Question

The following query was successful when I used in mysql

INSERT INTO user(`dev_id`,`email`) VALUES('123','456@gmail.com');

But in java jdbc I got this exception:

Can not issue data manipulation statements with executeQuery().
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:910)
    at com.mysql.jdbc.Statement.checkForDml(Statement.java:417)
    at com.mysql.jdbc.Statement.executeQuery(Statement.java:1140)

My table have 5 columns and 3 columns have default value =null;

Answer 1

executeQuery is only for issuing query statements. You need to be using executeUpdate for an insert, which is for statements (like INSERT ) that modify data. Ideally, you should also be using a PreparedStatement

Answer 2

而不是executeQuery()尝试使用execute()或executeUpdate()

Answer 3

如果u正在发出INSERT/UPDATE/DELETE语句，而不是用于执行SELECT语句的executeQuery() ，则调用executeUpdate()

Answer 4

You should use executeUpdate() instead of executeQuery() . JavaDoc:

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.

Note:This method cannot be called on a PreparedStatement or CallableStatement.

Parameters: sql - an SQL Data Manipulation Language (DML) statement, such as INSERT, UPDATE or DELETE; or an SQL statement that returns nothing, such as a DDL statement.

Also whenever problem arise - check javadoc and try googling first. Stackoverflow is a little bit delicate for your case.
