Question

sqlserver 查询字段在哪个表里

Answer 1

1、创建两张测试表，

create table test_col1(factory_id int, factory_name varchar2(20));

create table test_col2(factory_id int, factory_name varchar2(20));

2、查看test_col1的表结构，select * from user_tab_cols t where table_name = 'TEST_COL1'，有两个字段，

3、查看test_col2的表结构，select * from user_tab_cols t where table_name = 'TEST_COL2'，同样有两个字段，

4、查看factory_id、factory_name字段存在的所有表中记录情况，select * from user_tab_cols t where column_name in ('FACTORY_ID','FACTORY_NAME')，

Answer 2

下边是SQLSERVER中查询某字段在哪些表中含有的语法：
select sysobjects.name from syscolumns inner join sysobjects on syscolumns.id = sysobjects.id and sysobjects.xtype = 'u' where syscolumns.name = '字段名字'
