tblunnormalize
 transId(Pk)       docname    username  ZoneName  dateInsert
-------------      -------    --------  --------  ----------

我想要的是有一个unnormalize表，其中包含与所有这些表相关的数据。是否有可能编写程序在运行时插入数据意味着何时在tblmedAssign中插入数据表数据应该插入到unnormalize表中的特定时间？

你走了：

DELIMITER $$

DROP PROCEDURE IF EXISTS `medAssignProcedure`$$

CREATE

    PROCEDURE medAssignProcedure(IN transId INT, IN doctorId INT, IN medId INT )

    BEGIN
    DECLARE doctorname VARCHAR(100);
    DECLARE user_Name VARCHAR(100);
    DECLARE zone_name VARCHAR(100);
    DECLARE userId INT;
    DECLARE datetimenow DATETIME;
    SET datetimenow = NOW();
    INSERT INTO tblmedassign VALUES (transId,doctorId,medId,datetimenow);
    SET doctorname = (SELECT docname FROM tbldoctor WHERE docid = doctorId);
    SET userId = (SELECT usrid FROM tbldoctor WHERE docid = doctorId);
    SET user_Name = (SELECT username FROM tbluser WHERE usrid = userId);
    SET zone_name = (SELECT zonename FROM tblzone WHERE zone_id = (SELECT userzoneId FROM tbluser WHERE usrid = userId));   
    INSERT INTO tblunnormalize VALUES (transId, doctorname, user_Name, zone_name, datetimenow);

    END$$

DELIMITER ;

怎么写程序？
