下面是一个完整的示例,演示了如何在存储过程中使用临时表: CREATEPROCEDUREExampleProcedureASBEGIN-- 创建临时表CREATETABLE#TempTable (Column1INT,Column2VARCHAR(50));-- 插入数据INSERTINTO#TempTable (Column1, Column2)VALUES(1,'Data 1'),(2,'Data 2');-- 查询数据SELECTColumn1,Column2FROM#TempTable;...
Once your session or batch ends, SQL Server will clean up the temp table. On another note the ##Temp table behaves like a normal table. Everyone can see it, and there cannot be more than 1 ##Temp table with the same name. SQL Server will clean these ##Temp tables when the server ...

If a temporary table is created with a named constraint and the temporary table is created within the scope of a user-defined transaction, only one user at a time can execute the statement that creates the temp table. For example, if a stored procedure creates a temporary table with a name...

Note, however, that you can’t create another temporary table with the same name in the same session. SQL Server will tell you it already exists. See the example below: How to Avoid Slowing Down Your Database When Using SELECT INTO Temp Table ...

其实在SQL Server中存在两种临时表:局部临时表和全局临时表,局部临时表(Local temp table)以#前缀来标识,并且只能被创建它的连接所使用.全局临时表(Global temp table)以##前缀来进行标识,并且可以和其它连接所共享.局部临时表局部临时表不能够被其它连接所共享的原因其实是在SQL Server 2000中自动为局部临时表的表...
