在SQL查询分析器 动态SQL语句中where条件为变量时该如何写？

Answer 1

给你个参考吧：把要执行的语句写成sql字符串变量，执行变量即可

declare @sql varchar(1000)
declare @filter varchar(400)
declare @orderby varchar(50)
set @sql = ' select * from 你的表 '
set @filter = ' where 1=1 '
set @orderby = ' order by id desc '
if ....
set @filter = @filter + ' and 条件1 '
if ...
set @filter = @filter + ' and 条件2 '
-- 执行sql
exec( @sql + @filter + @orderby )

Answer 2

select * from table_name t where t.table_column=:B1
