mysql 存储过程的问题_Mysql_脚本之家

一开始用phpMyAdmin来执行,后来出现一堆错误,后来去掉了begin,end之后可以正常执行,但要执行存储过程,在phpMyAdmn中不行,而在mysql命令行文本框中就可以。 接下来又遇到更难的问题,在存储过程中加入预处理语句,更不行了,在mysql命令行文本框下执行同样,下面的运行记录,给大家参考,能否有高手来帮助。 复制代码 代码如下: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 <= 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$$ ERROR 1064 : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'inSta rtItem;inProductsPerPage; end' at line 10 //原本的存储过程语句 EATE PROCEDURE catalog_get_products_in_category( IN inCategoryId INT, IN inShortProductDescriptionLength INT, IN inProductsPerPage INT, IN inStartItem INT) BEGIN PREPARE statement FROM "SELECT p.product_id, p.name,IF <= ?, p.description, CONCAT(LEFT,'...')) AS description, p.price, p.discounted_price, p.thumbnail FROM product p INNER JOIN product_category pc ON p.product_id = pc.product_美高梅4858官方网站,id WHERE pc.category_id = ? ORDER BY p.display DESC LIMIT ?, ?"; SET @p1 = inShortProductDescriptionLength; SET @p2 = inShortProductDescriptionLength; SET @p3 = inCategoryId; SET @p4 = inStartItem; SET @p5 = inProductsPerPage; EXECUTE statement USING @p1, @p2, @p3, @p4, @p5; END$$ mysql> delimiter $$ mysql> CREATE 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 <= ?, p.descript ion, "> CONCAT(LEFT,'...'))
