请教一个更新问题。将lsh=SC123-2013--9-01-111更新成SC123 A-2013--9-01-111
数据表kc表，里边有lsh一项，有多条数据，都是SC123-开头，现在想把所有SC123替换成SC123 A-,如何成批替换?LSH是唯一的。
kc:
lsh mc
SC123-2013--9-01-111 A
SC123-2013--9-01-113 B
SC123-2013--10-01-111 C
SC123-2013--11-01-111 D
SC123-2013--9-01-25 E
SC123-2013--9-01-26 F
替换完后为
lsh mc
SC123 A-2013--9-01-111 A
SC123 A-2013--9-01-113 B
SC123 A-2013--10-01-111 C
SC123 A-2013--11-01-111 D
SC123 A-2013--9-01-25 E
SC123 A-2013--9-01-26 F

[解决办法]

update [kc] set [lsh] =stuff([lsh],6,0,'A') from [kc]
