请帮忙解决以下更新问题!!!偶想了三天半没解决~
zd1
C
C
C
如果要在zd1后面加上数字,要怎么写语句?(C1,C2,C3...C12,c13...c20,c21)
请注释以下语句的意思:(有能修复表 'sysindexes '一致性错误的语句吗?)
exec sp_msforeachtable 'DBCC CHECKTABLE( ' '? ' ',REPAIR_REBUILD) '
exec sp_msforeachtable 'DBCC DBREINDEX( ' '? ' ') '
------解决方案--------------------select id=identity(int,1,1) , * into test from tb
select zd1 + cast(id as varchar) from test
------解决方案--------------------declare @t table(CODE varchar(8))
insert into @t select 'C '
insert into @t select 'C '
insert into @t select 'C '
insert into @t select 'C '
insert into @t select 'C '
insert into @t select 'C '
insert into @t select 'C '
insert into @t select 'C '
declare @i int
set @i=0
update @t set @i=@i+1,CODE=CODE+rtrim(@i)
select * from @t
