mysql 存儲(chǔ)過程的問題

更新時(shí)間：2009年06月05日 23:57:46 作者：

最近我接觸了一本php 與 mysql,老外寫的一本書，書中有個(gè)tshirtshop網(wǎng)店代碼，其中操作數(shù)據(jù)庫(kù)的大多用的是mysql存儲(chǔ)過程

一開始用phpMyAdmin來執(zhí)行，后來出現(xiàn)一堆錯(cuò)誤，后來去掉了begin,end之后可以正常執(zhí)行，但要執(zhí)行存儲(chǔ)過程，在phpMyAdmn中不行，而在mysql命令行文本框中就可以。
接下來又遇到更難的問題，在存儲(chǔ)過程中加入預(yù)處理語(yǔ)句，更不行了，在mysql命令行文本框下執(zhí)行同樣，下面的運(yùn)行記錄，給大家參考，能否有高手來幫助。

復(fù)制代碼代碼如下:

mysql> CREATE PROCEDURE catalog_get_products_in_category( 
-> IN inCategoryId INT, IN inShortProductDescriptionLength INT, 
-> IN inProductsPerPage INT, IN inStartItem INT) 
-> begin 
-> SELECT p.product_id, p.name,IF(LENGTH(p.description) <= inShortProductD 
escriptionLength, p.description, 
-> CONCAT(LEFT(p.description, inShortProductDescriptionLength),'...')) AS 
description, p.price, p.discounted_price, p.thumbnail 
-> FROM product p INNER JOIN product_category pc ON p.product_id = pc.pro 
duct_id 
-> WHERE pc.category_id = inCategoryId 
-> ORDER BY p.display DESC 
-> LIMIT inStartItem;inProductsPerPage; 
-> end$$ 
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that 
corresponds to your MySQL server version for the right syntax to use near 'inSta 
rtItem;inProductsPerPage; 
end' at line 10 

//原本的存儲(chǔ)過程語(yǔ)句
EATE PROCEDURE catalog_get_products_in_category(
IN inCategoryId INT, IN inShortProductDescriptionLength INT,
IN inProductsPerPage INT, IN inStartItem INT)
BEGIN
PREPARE statement FROM
"SELECT p.product_id, p.name,IF(LENGTH(p.description) <= ?, p.description,
CONCAT(LEFT(p.description, ?),'...')) AS description, p.price, p.discounted_price, p.thumbnail
FROM product p INNER JOIN product_category pc ON p.product_id = pc.product_id
WHERE pc.category_id = ?
ORDER BY p.display DESC
LIMIT ?, ?";
SET @p1 = inShortProductDescriptionLength;
SET @p2 = inShortProductDescriptionLength;
SET @p3 = inCategoryId;
SET @p4 = inStartItem;
SET @p5 = inProductsPerPage;
EXECUTE statement USING @p1, @p2, @p3, @p4, @p5;
END$$

上面有兩個(gè)存儲(chǔ)過程，一個(gè)不用預(yù)處理語(yǔ)句，一個(gè)用了預(yù)處理語(yǔ)句，
之后，向作者發(fā)過郵件，沒有答復(fù)，又給mysql官方發(fā)過郵件，同樣沒答復(fù)?，F(xiàn)今只能求助諸位高人。
