--drop table xxx
create table xxx(id int,abc varchar(100),xxx varchar(100))
insert into xxx
select 1,'163.com','.com' union all
select 2,'xxx','163.com'
运行上面的查找代码,会返回这样的查询结果:
/*table_name column_name column_search_value
xxx abc 163.com
xxx xxx 163.com*/
if OBJECT_ID('temp_search_table') is not null
drop table temp_search_table
