  • sqlserver 多语句表值函数例子

    多语句表值函数顾名思义是返回了一张表,可以传入多个参数

    1.定义

     1 Use AdventureWorks2014;
     2 go
     3 if exists(select * from sys.objects where name='udf_SEL_SalesQuota')
     4 drop function dbo.udf_SEL_SalesQuota;
     5 go
     6 CREATE FUNCTION dbo.udf_SEL_SalesQuota ( @BusinessEntityID int, @ShowHistory bit )
     7 RETURNS @SalesQuota TABLE 
     8     (
     9         BusinessEntityID int, 
    10         QuotaDate datetime, 
    11         SalesQuota money
    12     )
    13 as
    14 begin
    15     INSERT Into @SalesQuota(BusinessEntityID, QuotaDate, SalesQuota)
    16     SELECT BusinessEntityID, ModifiedDate, SalesQuota
    17     FROM Sales.SalesPerson
    18     WHERE BusinessEntityID = @BusinessEntityID;
    19 
    20     IF @ShowHistory = 1
    21          begin
    22             INSERT Into @SalesQuota(BusinessEntityID, QuotaDate, SalesQuota)
    23             SELECT BusinessEntityID, QuotaDate, SalesQuota
    24             FROM Sales.SalesPersonQuotaHistory
    25             WHERE BusinessEntityID = @BusinessEntityID;
    26          end
    27 
    28     return
    29 
    30 end

    2.调用

    1 Use AdventureWorks2014;

    3 SELECT BusinessEntityID, QuotaDate, SalesQuota      
    4 FROM dbo.udf_SEL_SalesQuota (275,0);
