PHP SQL UPDATE查詢問題

Question

我在使用此更新查詢時遇到問題。INSERT可以正常工作。我的INSERT查詢和UPDATE查詢如下所示，

這是我一直得到的錯誤。

db_exec:DB Error:

                )

        )

                )

            [function] => require
        )

)

謝謝你的幫助 ：）

Answer 1

刪除WHERE之前的最后一個逗號

Answer 2

在Where子句之前，您有一個多余的逗號

UPDATE vms2 set invoiceid='', slicenseinfo='testVM',  manufacturerid='692', hyp='6', stitle='UBER', vmg='UBER', sversion='1716',  sinfo='', purchdate='1367712000', licqty='7', lictype='192', dns='', ipv4='10.2.36.3', ipv4dns='102.32.3.55', remip='110.2.3.3', remipdns='100.32.3.32', ipv6='', hdd='', ram='', cores=''  WHERE id=14

這應該工作。

Answer 3

將UPDATE命令更新為此

 UPDATE vms2 set invoiceid='', slicenseinfo='testVM',  manufacturerid='692', hyp='6', stitle='UBER', vmg='UBER', sversion='1716',  sinfo='', purchdate='1367712000', licqty='7', lictype='192', dns='', ipv4='10.2.36.3', ipv4dns='102.32.3.55', remip='110.2.3.3', remipdns='100.32.3.32', ipv6='', hdd='', ram='', cores=''  WHERE id=14`
