sql server学习笔录1（sql存储过程，表变量的运用）

这篇博客旨在存储过程的写法，表变量的运用，及如何执行存储过程

一 存储过程

use BookStoreZone

Go

CREATE  PROCEDURE [dbo].[UP_InsertBookCatalog]
@StoreID INT,
@Priority INT,
@BookID1 INT,
@BookType1 INT,
@BookID2 INT,
@BookType2 INT
AS
BEGIN
DECLARE @itemNum VARCHAR(15),  --sp内部的变量
SET @itemNum=RTRIM(CAST(@ItemNumber AS varchar(15)))
SET @Priority=1 ;
DECLARE @TableId TABLE (table_id INT NOT NULL primary key,
						BookId INT,BookType INT)
INSERT INTO @TableId
(
	table_id,
	BookIId,
	BookType )
VALUES
(
	1,
	@BookID1 ,
	@BookType1
 )

INSERT INTO @TableId
(
	table_id,
	BookId2,
	BookType2
)
VALUES
(
	2,
	@BookId2,
	@BookType2
)
BEGIN
INSERT INTO dbo.BookStore
(StoreID, BookId,BookName, BookType, Priority)
SELECT @StoreID, a.BookId,c.BookName,c.BookType,@Priority 
FROM dbo.BookMenu a WITH(NOLOCK)
INNER JOIN User c WITH(NOLOCK)
ON a.BookId = c.BuyBookId
	AND (
		CASE a.BookType WHEN 'D' THEN 2
		ELSE 1 END
	) = c.BuyBookType
WHERE a.BookId IN (SELECT ti.BookID FROM @TableId ti WHERE ti.BookType=3)
	AND a.[Status] = 1
	AND NOT EXISTS ( --返回1 则有值，exists=true ，整个and的结果为false
		SELECT TOP 1 1 FROM dbo.BookMenu d WITH(NOLOCK)
		WHERE d.BookID = @StoreID
			AND d.BookId = a.BookId
			AND d.BookType = (
				CASE a.BookType WHEN 'D' THEN 2
				ELSE 1 END))
END	
END	
GO
 

二 执行存储过程

在sql server 2008 中有自动执行的方法，只要给出参数变量就成了，一下是自动执行后的sql脚本。

DECLARE	@return_value int

EXEC	@return_value = [dbo].[UP_InsertBookCatalog]
		@StoreID = 105,
                @Priority = 1,
                @BookID1=3,
		@BookType1=5,
		@BookID2=3,
		@BookType2=5,

SELECT	'Return Value' = @return_value

也可

EXEC [dbo].[UP_InsertBookCatalog] 105,1,3,5,3,5
