我的Sql存储的先例不能正常工作

标签： php mysql codeigniter

我正在尝试编码存储的先验来管理公司的叶子，因为叶子应该定期记入每个员工。我正在使用表格

erp_leave_policy => Describing Leave policy, 
erp_employees    => Describing Employees, 
erp_clients      => Describing Employees are belonged to which Client, 
erp_employee_leave_policy => Describing leave policy of employees.

我在存储过程中使用以下查询

SELECT lpc_id,emp_id  FROM erp_leave_policy,erp_employees,erp_clients,erp_employee_leave_policy 
                WHERE emp_status=1 AND cli_status=1 AND lpc_status=1 AND 
                emp_id = elp_fk_employees AND lpc_id = elp_fk_leave_policy AND cli_id = emp_fk_clients;

它没有问题，工作正常。

但是在我的存储过程中，此查询无效。我正在使用codeigniter。我的代码如下。

$this->db->query("DROP FUNCTION IF EXISTS inserter;");
$q = "  CREATE FUNCTION inserter(emp_id bigint,lpc_id int) RETURNS boolean DETERMINISTIC
            BEGIN

            INSERT INTO aaa_test (aaa_lpc_id,aaa_emp_id) VALUES (lpc_id, emp_id);   

             RETURN 1;
            END;";

$this->db->query($q);
$this->db->query("DROP PROCEDURE IF EXISTS start_credit_test;");
$q = " CREATE PROCEDURE start_credit_test()
        BEGIN
            DECLARE v_finished INTEGER DEFAULT 0;
            DECLARE lpc_id INT(11) DEFAULT 0;
            DECLARE emp_id BIGINT(20) DEFAULT 0;


            DEClARE emp_cursor CURSOR FOR 

            SELECT lpc_id,emp_id  FROM erp_leave_policy,erp_employees,erp_clients,erp_employee_leave_policy 
            WHERE emp_status=1 AND cli_status=1 AND lpc_status=1 AND 
            emp_id = elp_fk_employees AND lpc_id = elp_fk_leave_policy AND cli_id = emp_fk_clients;

            DECLARE CONTINUE HANDLER 
                   FOR NOT FOUND SET v_finished = 1;

            OPEN emp_cursor;

                get_emp: LOOP

                    FETCH emp_cursor INTO lpc_id,emp_id;

                    IF v_finished = 1 THEN 
                    LEAVE get_emp;
                    END IF;

                    inserter(emp_id,lpc_id);

                END LOOP get_emp;

            CLOSE emp_cursor;

           END ";


$this->db->query($q);

$query = $this->db->query("CALL start_credit_test();");

错误如下

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(emp_id,lpc_id); END LOOP get_emp; CLO' at line 27

CREATE PROCEDURE start_credit_test() BEGIN DECLARE v_finished INTEGER DEFAULT 0; DECLARE lpc_id INT(11) DEFAULT 0; DECLARE emp_id BIGINT(20) DEFAULT 0; DEClARE emp_cursor CURSOR FOR SELECT lpc_id,emp_id FROM erp_leave_policy,erp_employees,erp_clients,erp_employee_leave_policy WHERE emp_status=1 AND cli_status=1 AND lpc_status=1 AND emp_id = elp_fk_employees AND lpc_id = elp_fk_leave_policy AND cli_id = emp_fk_clients; DECLARE CONTINUE HANDLER FOR NOT FOUND SET v_finished = 1; OPEN emp_cursor; get_emp: LOOP FETCH emp_cursor INTO lpc_id,emp_id; IF v_finished = 1 THEN LEAVE get_emp; END IF; inserter(emp_id,lpc_id); END LOOP get_emp; CLOSE emp_cursor; END

我尝试使用

替换inserter(emp_id,lpc_id);而不调用函数inserter（）来尝试此代码 
INSERT INTO aaa_test (aaa_lpc_id,aaa_emp_id) VALUES (lpc_id, emp_id);

现在它没有显示错误。但没有插入表aaa_test。 此外，在DELIMITER //之前使用CREATE PROCEDURE start_credit_test()时，以及当我致电$this->db->query()时，它也会显示错误。例如

$q = " DELIMITER //
        CREATE PROCEDURE start_credit_test()
        BEGIN
         .........
        .............";
 $this->db->query($q);

错误如下

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER // CREATE PROCEDURE start_credit_test() BEGI' at line 1

你能帮忙吗

关于分隔符的问题

$q = " DELIMITER $$;
CREATE PROCEDURE start_credit_test()
    BEGIN
        DECLARE v_finished INTEGER DEFAULT 0;
        DECLARE lpc_id INT(11) DEFAULT 0;
        DECLARE emp_id BIGINT(20) DEFAULT 0;


        DEClARE emp_cursor CURSOR FOR 

        SELECT lpc_id,emp_id  FROM erp_leave_policy,erp_employees,erp_clients,erp_employee_leave_policy 
        WHERE emp_status=1 AND cli_status=1 AND lpc_status=1 AND 
        emp_id = elp_fk_employees AND lpc_id = elp_fk_leave_policy AND cli_id = emp_fk_clients;

        DECLARE CONTINUE HANDLER 
               FOR NOT FOUND SET v_finished = 1;

        OPEN emp_cursor;

答案 1 :(得分：0)

调用inserter过程附近的语法错误，您应该使用CALL命令 - 

...
CALL inserter(emp_id,lpc_id);
...

另一个，我认为你可以简化你的任务：

  1. 只使用一个存储过程，甚至只使用一个语句 -
  2. 使用
    3. 避免光标

    有INSERT...SELECT statement在一个命令中插入来自另一个数据集的记录，例如 - 

    INSERT INTO aaa_test (aaa_lpc_id, aaa_emp_id)
  SELECT
    lpc_id,
    emp_id
  FROM erp_leave_policy,
       erp_employees,
       erp_clients,
       erp_employee_leave_policy
  WHERE emp_status = 1
  AND cli_status = 1
  AND lpc_status = 1
  AND emp_id = elp_fk_employees
  AND lpc_id = elp_fk_leave_policy
  AND cli_id = emp_fk_clients;

错误可能包含在：DECLARE v_finished INTEGER DEFAULT 0;

中

更改为：DECLARE v_finished INT(11) DEFAULT 0;

答案 3 :(得分：0)

谢谢大家。 我按照你的建议纠正了我的代码。并更改了我使用存储过程声明的变量的名称。那就是我改变了     DECLARE lpc_id INT(11) DEFAULT 0; DECLARE emp_id BIGINT(20) DEFAULT 0; 如     DECLARE my_lpc_id INT(11) DEFAULT 0; DECLARE my_emp_id BIGINT(20) DEFAULT 0; 然后我改变了     call inserter(emp_id,lpc_id); 如     INSERT INTO aaa_test (aaa_emp_id,aaa_lpc_id) VALUES (my_emp_id,my_lpc_id);

现在我的总代码为

DELIMITER $$;
CREATE PROCEDURE start_credit_test()
BEGIN
    DECLARE v_finished INT(11) DEFAULT 0;
    DECLARE my_lpc_id INT(11) DEFAULT 0;
    DECLARE my_emp_id BIGINT(20) DEFAULT 0;


    DEClARE emp_cursor CURSOR FOR 

    SELECT lpc_id,emp_id  FROM erp_leave_policy,erp_employees,erp_clients,erp_employee_leave_policy 
            WHERE emp_status=1 AND cli_status=1 AND lpc_status=1 AND 
            emp_id = elp_fk_employees AND lpc_id = elp_fk_leave_policy AND cli_id = emp_fk_clients;

    DECLARE CONTINUE HANDLER FOR NOT FOUND SET v_finished = 1;

    OPEN emp_cursor;

        get_emp: LOOP

            FETCH emp_cursor INTO my_lpc_id,my_emp_id;

            IF v_finished = 1 THEN 
            LEAVE get_emp;
            END IF;

            INSERT INTO aaa_test (aaa_emp_id,aaa_lpc_id) VALUES (my_emp_id,my_lpc_id);  

        END LOOP get_emp;

    CLOSE emp_cursor;

    END$$;
    DELIMITER ;

它会将值aaa_test插入为 Click Here

但是当我调用函数插入器时，它又出现了错误

PROCEDURE abn_erp.inserter does not exist

我将整个代码放在

之下 
            DROP FUNCTION IF EXISTS inserter;

            DELIMITER $$;
            CREATE FUNCTION inserter(emp_id bigint, lpc_id int) RETURNS boolean DETERMINISTIC
            BEGIN

                INSERT INTO aaa_test (aaa_emp_id,aaa_lpc_id) VALUES (emp_id,lpc_id);   

                RETURN 1;
            END $$;
            DELIMITER ;


            DROP PROCEDURE IF EXISTS start_credit_test;

            DELIMITER $$;
            CREATE PROCEDURE start_credit_test()
                BEGIN
                    DECLARE v_finished INT(11) DEFAULT 0;
                    DECLARE my_lpc_id INT(11) DEFAULT 0;
                    DECLARE my_emp_id BIGINT(20) DEFAULT 0;


                    DEClARE emp_cursor CURSOR FOR 

                    SELECT lpc_id,emp_id  FROM erp_leave_policy,erp_employees,erp_clients,erp_employee_leave_policy 
                            WHERE emp_status=1 AND cli_status=1 AND lpc_status=1 AND 
                            emp_id = elp_fk_employees AND lpc_id = elp_fk_leave_policy AND cli_id = emp_fk_clients;

                    DECLARE CONTINUE HANDLER FOR NOT FOUND SET v_finished = 1;

                    OPEN emp_cursor;

                        get_emp: LOOP

                            FETCH emp_cursor INTO my_lpc_id,my_emp_id;

                            IF v_finished = 1 THEN 
                            LEAVE get_emp;
                            END IF;

                             call inserter(my_emp_id,my_lpc_id);  

                        END LOOP get_emp;

                    CLOSE emp_cursor;

                    END $$;
                    DELIMITER ;

但是当我调用start_credit_test（）时 $this->db->query("CALL start_credit_test();") 收到错误PROCEDURE abn_erp.inserter does not exist
