CREATE FUNCTION sqlserver用户定义函数 创建用户定义函数，它是返回值的已保存的 Transact-SQL 例程。用户定义函数不能用于执行一组修改全局数据库状态的操作。与系统函数一样，用户定义函数可以从查询中唤醒调用。也可以像存储过程一样，通过 EXECUTE 语句执行 创建用户定义函数，它是返回值的已保存的 Transact-SQL 例程...

I suppose you could do what you want if you're okay with building your query using dynamic SQL, for example you could create a function like this: CREATE FUNCTION dbo.Limit(@pn VARCHAR(12), @ps VARCHAR(12)) RETURNS NVARCHAR(255) WITH SCHEMABINDING AS BEGIN RETURN (N' OFFSET ' + @pn...
are deterministic. Deterministic expressions always return the same result whenever they're evaluated with a specific set of input values. Only deterministic functions can participate in deterministic expressions. For example, theDATEADDfunction is deterministic because it always returns the same result for...
