java.sql.SQLException : Parameter number 2 is not an OUT parameter

Question

我在运行时遇到错误:

1. cs = getCon1().prepareCall("{CALL SaveLabourWageDetails(?,?)}");

2. cs.setString(1, user.getUserId());

3. cs.registerOutParameter(2, java.sql.Types.INTEGER); //<--- ERROR at this line

4. cs.execute();

5. String lastIsertId=cs.getString(2);

存储过程是:

CREATE

    PROCEDURE `cheque_alert`.`SaveLabourDetailsHead`(IN wage_entered_by VARCHAR(10),OUT LastInsertId INT)

    BEGIN
    INSERT INTO `cheque_alert`.`labour_wage_head`
            (
             `wage_entered_by`,
             `entered_date_time`)
    VALUES (wage_entered_by,
         NOW());

          SELECT LAST_INSERT_ID() INTO LastInsertId;

    END$$

DELIMITER ;

请指出这段代码的问题..

Answer 1

您调用了错误的程序。您有过程 SaveLabourDetailsHead 并且您正在调用

1. cs = getCon1().prepareCall("{CALL SaveLabourWageDetails(?,?)}");  
                                         ↑  

更改为，

1. cs = getCon1().prepareCall("{CALL SaveLabourDetailsHead(?)}");  

设置字符串参数wage_entered_by。
