SQl Server 动态SQL给变量赋值 和OBJECTPROPERTY函数使用及判断表 存储过程 视图等是否存在

--------------------------------------------SQl Server 判断表 存储过程 视图等是否存在--------------------------------------

select * from dbo.sysobjects

where id = object_id(N'ViewName')

and OBJECTPROPERTY(id, N'IsView') = 1

select * from dbo.sysobjects

where id = object_id(N'TableName')

and OBJECTPROPERTY(id, N'IsUserTable') = 1

select * from dbo.sysobjects

where id = object_id(N'ProcecureName')

and OBJECTPROPERTY(id, N'IsProcedure') = 1

--------------------------------------------SQl Server OBJECTPROPERTY函数使用--------------------------------------------

--注:函数当中不能用动态SQL

DECLARE @Sql NVARCHAR(200);

DECLARE @TableName NVARCHAR(100);

DECLARE @TOTAL_COUNT INT;--要返回的值

SET @TableName='YourTableName';

SET @Sql=N'SELECT @COUNT =ISNULL(MAX(IDENTITYCOL),0) FROM '+@TableName;

EXECUTE SP_EXECUTESQL @Sql,N'@COUNT INT OUTPUT', @TOTAL_COUNT OUTPUT;

SELECT @TOTAL_COUNT AS CurMaxID;
