下面为您介绍的是查询表的字段名的sql语句写法，sql语句可以实现许多的功能，希望可以您在学习sql语句使用方面获得启示。 1. select name from syscolumns where id = (select id from sysobjects where type = 'u' and name = '相应表名') 2. 3. 或者 4. 5. select name from syscolumns where id = object_id('相应表名') 用以上sql语句输入
在Oracle中查询锁表及解锁:
锁表查询的代码有以下的形式:
select count(*) from v$locked_object;
select * from v$locked_object;
查看哪个表被锁:
select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id;
查看是哪个session
