如何在动态 sql 中写入 '1=1'
How to write a '1=1' within dynamic sql
有人可以更正吗？
declare @g varchar(max)
set @g = 'select *
from person.person
where firstname like '%t' '
set @g = @g + 'or firstname like''' +('a'= 'a')+ ''''
exec (@g)
您的基本查询应该有 1=1
set @g = 'select *
from person.person
where 1=1 '
set @g = @g + 'and firstname like ''%t'' '
set @g = @g + 'or firstname like ''' +('a'= 'a')+ ''''
如果您需要对条件进行分组，它们都需要在一起：
set @g = @g +'(firstname like ''%t%'' or firstname like ''%a'')'
