Answer 1

删除WHERE之前的最后一个逗号

Answer 2

You have an extra comma before the Where clause which is not required

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

This should work.

Answer 3

将UPDATE命令更新为此

 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`
