sql判断存储过程是否存在
1 判断是否存在
Sql代码
if exists ( * from sys.databases where name = ’数据库名’)
drop database [数据库名] if exists (select * from sys.databases where name = ’数据库名’)
drop database [数据库名]
2 判断表是否存在
Sql代码
if exists (select * from sysobjects where id = object_id(N’[表名]’) and OBJECTPROPERTY(id, N’IsUserTable’) = 1)
drop table [表名] if exists (select * from sysobjects where id = object_id(N’[表名]’) and OBJECTPROPERTY(id, N’IsUserTable’) = 1)
drop table [表名]
3 判断存储过程是否存在
Sql代码
if exists (select * from sysobjects where id = object_id(N’[存储过程名]’) and OBJECTPROPERTY(id, N’IsProcedure’) = 1)
drop procedure [存储过程名] if exists (select * from sysobjects where id = object_id(N’[存储过程名]’) and OBJECTPROPERTY(id, N’IsProcedure’) = 1)
drop procedure [存储过程名]
4 判断临时表是否存在
