declare @rowcount int;
exec ('select count(['+@Colm+']) # from ['+@Table+']')
如何将count 的值赋给@rowcount

[zlp321002]

declare @rowcount int,
@sqls nvarchar(4000)
set @sqls='select @rowcount =count('+@Colm+') from ['+@Table+']'
exec sp_executesql @sqls,N'@rowcount int output',@rowcount output
select @rowcount

改成。
exec ('select '+@Colm+' from ['+@Table+']')
set @rowcount=@@rowcount
