IF EXISTS (SELECT*FROMdbo.SysObjectsWHEREID = object_id(N'TEMP_TBL')ANDOBJECTPROPERTY(ID,'IsTable') = 1) PRINT'存在' ELSE PRINT'不存在' 2、临时表是否存在: 方法一: 1 2 3 4 5 6 7 use fireweb; go if exists(select*fromtempdb..sysobjectswhereid=object_id('tempdb..##TEMP_TBL')) ...
判断临时表是否存在方法如下: ifOBJECT_ID(N'tempdb..#TempTable',N'U')isnotnullprint'存在'elseprint'不存在'ifexists(select*fromtempdb.dbo.sysobjectswhereid=object_id(N'tempdb..#TempTable')andtype='U')print'存在'elseprint'不存在' 临时表本身也是一张表,所以判断存在的方法和普通表相同,只不过需...

if exists ( object_id('Tempdb..#temp') ) 也不行，因为无论是否存在表#temp都会返回一行的，所以这个条件永远成立 应该用 if ( object_id('Tempdb..#temp') is not null)DROP TABLE #temp GO
下面我们来看一个创建SQL Server临时表的例子: CREATE TABLE dbo.#News ( News_id int NOT NULL, NewsTitle varchar(100), NewsContent varchar(2000), NewsDateTime datetime ) 1. 2. SQL Server临时表可以创建索引,也可以定义统计数据,所以可以用数据定义语言(DDL)的声明来阻止临时表添加的限制,约束,并参照...
IF NOT EXISTS (SELECT * FROM sysobjects where id = OBJECT_ID(N'temp_tableSpaceInfo') AND OBJECTPROPERTY(id, N'IsUserTable') = 1) BEGIN --不存在则创建 CREATE TABLE temp_tableSpaceInfo (name NVARCHAR(128), rows char(11), reserved VARCHAR(18), ...

以SQL Server为例,可以使用INFORMATION_SCHEMA.TABLES视图来查询表的信息,以下是一个查询示例,用于检查名为TempTable的临时表是否存在: IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = 'TempTable' AND TABLE_TYPE = 'LOCAL_TEMPORARY') ...
if object_id('tempdb..#my_table_temp')isnotnullbeginprint('存在')endelsebeginprint('不存在')end 【创建临时表】 1)可以先判断是否存在,存在先删除再创建临时表 drop table #my_temp_table 2)创建临时表和创建普通表一样 create table #my_temp_table(字段名 数据类型,...) ...
if exists( select 1 from tempdb.sys.tables where upper(name) like upper('%tempTabIndall%') ) drop table #tempTabIndall ; create table #tempTabIndall( ObjectID bigint, IndexId bigint, PartitionID bigint, allocation_unit_id bigint ...
