mysql - SQL CONCAT 函数

Question

我想创建一个像这样的连接:

CONCAT(PEEL.orderno+'-'+PEEL.ordersuf+'-'+PEEL.product) AS“唯一”

    SELECT        OEEL.invoicedt, UCASE(OEEL.whse) AS Whse, OEEL.orderno, OEEL.ordersuf, OEEL.custno, UCASE(OEEL.shipto) AS Shipto, UCASE(OEEL.slsrepin) AS Slsrepin, 
                         UCASE(OEEL.slsrepout) AS Slsrepout, OEEL.returnfl, OEEL.netamt, OEEL.wodiscamt, OEEL.discamtoth, OEEL.qtyship, OEEL.commcost, ICSS.csunperstk, 
                         UCASE(ICSD.name) AS Name, UCASE(ICSD.region) AS Region, UCASE(OEEL.prodcat) AS Prodcat, UCASE(SASTA.descrip) AS Descrip, UCASE(OEEL.transtype) 
                         AS Transtype, UCASE(ARSS.user2) AS User2, OEEL.transdt, ICSS.transdt AS "ICSS.Transdt", ICSD.transdt AS "ICSD.Transdt", SASTA.transdt AS "SASTA.Transdt", 
                         ARSS.transdt AS "ARSS.Transdt", { fn CURDATE() } AS CURDATE1, { fn CURTIME() } AS CURTIME2, 
                         CASE WHEN OEEL.returnfl = '0' THEN (OEEL.netamt - OEEL.wodiscamt - OEEL.discamtoth) ELSE (- 1 * (OEEL.netamt - OEEL.wodiscamt - OEEL.discamtoth)) 
                         END AS "SALES", CASE WHEN OEEL.returnfl = '0' THEN (OEEL.qtyship * OEEL.commcost * NVL(ICSS.csunperstk, 1)) 
                         ELSE (- 1 * OEEL.qtyship * OEEL.commcost * NVL(ICSS.csunperstk, 1)) END AS "COST", 
                         (CASE WHEN OEEL.returnfl = '0' THEN (OEEL.netamt - OEEL.wodiscamt - OEEL.discamtoth) ELSE (- 1 * (OEEL.netamt - OEEL.wodiscamt - OEEL.discamtoth)) END) 
                         - (CASE WHEN OEEL.returnfl = '0' THEN (OEEL.qtyship * OEEL.commcost * NVL(ICSS.csunperstk, 1)) 
                         ELSE (- 1 * OEEL.qtyship * OEEL.commcost * NVL(ICSS.csunperstk, 1)) END) AS GP

FROM            { oj { oj { oj { oj PUB.oeel OEEL LEFT OUTER JOIN
                         PUB.icss ICSS ON OEEL.cono = ICSS.cono AND OEEL.shipprod = ICSS.prod AND OEEL.icspecrecno = ICSS.icspecrecno } LEFT OUTER JOIN
                         PUB.icsd ICSD ON OEEL.cono = ICSD.cono AND OEEL.whse = ICSD.whse } LEFT OUTER JOIN
                         PUB.sasta SASTA ON OEEL.cono = SASTA.cono AND OEEL.prodcat = SASTA.codeval } LEFT OUTER JOIN
                         PUB.arss ARSS ON OEEL.cono = ARSS.cono AND OEEL.custno = ARSS.custno AND OEEL.shipto = ARSS.shipto }
WHERE        (OEEL.cono = 1) AND (OEEL.invoicedt BETWEEN { d '2014-06-02' } AND { d '2014-06-03' }) AND (SASTA.codeiden IN ('C', 'c'))



ORDER BY OEEL.custno, OEEL.shipto, OEEL.prodcat

Answer 1

该函数的变量之间有 +(在 MySQL 中不是连接符号)。

尝试:-

CONCAT_WS('-', OEEL.orderno, OEEL.ordersuf, OEEL.prodcat) AS `Unique`

CONCAT_WS 进行连接与分隔符。第一个参数是分隔符，其他参数连接在一起。
