mysql存储过程语法错误

Question

好的，这只是我编写的第二个存储过程。我想你会明白的，我正在尝试关闭信用额度以及所有发票、费用、票据等。但我收到语法错误。目标是调用 close_account_proc(398985994)

DELIMITER $$

CREATE
    PROCEDURE `cc`.`close_account_proc`(cid INT)
    @uid_usr := uid_usr FROM credit_acc WHERE type_acc = 'init' AND credit_used_acc = cid;
    UPDATE credit_acc SET status_acc = 'closed', void_date_acc = NOW() WHERE credit_used_acc = cid;
    UPDATE payment_acc SET status_acc = 'voided', void_date_acc = NOW()  WHERE creditid_acc = cid;
    UPDATE sbal_sbl SET status_sbl = 'voided', void_date_sbl = NOW()  WHERE credit_used_acc = cid;
    INSERT INTO notes_not SET uid_usr = @uid_usr, initials_not = 'SYS',status_not = 'complete', date_not = NOW(), text_not = 'Closed credit line '.cid;
    UPDATE invoices_inv SET status_inv = 'voided', void_date_inv = NOW()  WHERE credit_used_acc = cid;
    BEGIN
    END$$

DELIMITER ;

所以，无论如何，我收到此错误:您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，了解在第 5 行的 '@uid_usr := uid_usr from Credit_acc where type_acc = 'init' and Credit_used_acc ' 附近使用的正确语法。

有什么想法吗？

DELIMITER $$

CREATE PROCEDURE `cc`.`close_account_proc`(cid INT)
BEGIN
    /* Check that it's what you wanted */
    SELECT  uid_usr
    INTO    @uid_usr
    FROM    credit_acc
    WHERE   type_acc = 'init'
            AND credit_used_acc = cid;

    UPDATE credit_acc SET status_acc = 'closed', void_date_acc = NOW() WHERE credit_used_acc = cid;
    UPDATE payment_acc SET status_acc = 'voided', void_date_acc = NOW()  WHERE creditid_acc = cid;
    UPDATE sbal_sbl SET status_sbl = 'voided', void_date_sbl = NOW()  WHERE credit_used_acc = cid;

    /* Check that it's what you wanted */

    INSERT
    INTO    notes_not (uid_usr, initials_not, status_not, date_not, text_not)
    VALUES  (@uid_usr, 'SYS', 'complete', NOW(), CONCAT('Closed credit line ', cid));

    UPDATE invoices_inv SET status_inv = 'voided', void_date_inv = NOW()  WHERE credit_used_acc = cid;
END
