Question

我在mysql中编写了UNION代码，但它无效。

请帮忙。

SELECT * FROM (`am_glmaster`) WHERE 
`logid_status` IN ('DISPATCHED','DELIVERED', 'COMPLETE') 
 AND `dispatch_from` =  'New Delhi'
UNION SELECT *
FROM (`glmaster_history`)
WHERE `logid_status` IN ('DISPATCHED', 'DELIVERED', 'COMPLETE') 
AND `glmaster_history`.`dispatch_from` =  'New Delhi'

给出错误 - ＃1064 - 您的SQL语法出错;检查手册，对应右边的MySQL服务器版本语法在＆＃39; WHERE logid_status IN附近使用（＆＃39; DISPATCHED＆＃39;，＆＃39;交付＆＃39;，＆＃39;完成＆＃39;）和'glmaster_h＆＃39;在第4行

试试这个：

SELECT * 
    FROM 
        am_glmaster 
    WHERE 
        logid_status IN ('DISPATCHED','DELIVERED', 'COMPLETE') 
    AND 
        dispatch_from =  'New Delhi'
UNION 
SELECT *
    FROM 
        glmaster_history
    WHERE 
        logid_status IN ('DISPATCHED', 'DELIVERED', 'COMPLETE') 
    AND 
        dispatch_from =  'New Delhi'

联盟不在Mysql中工作
