Syntax for input parameters in a MySQL query
提问by Simon
We recently switched a database from MSSQL to MySQL and the queries that uses parameters does'nt work anymore.
我们最近将数据库从 MSSQL 切换到 MySQL,并且使用参数的查询不再有效。
Here's an example of a query in MSSQL:
以下是 MSSQL 中的查询示例:
SELECT * FROM users u WHERE u.ID = :id
Normally, the parameter browser would popup and ask me for a value for :id, but in MySQL I get this error :
通常,参数浏览器会弹出并要求我输入 :id 的值,但在 MySQL 中我收到此错误:
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 ':id'
您的 SQL 语法有错误;检查与您的 MySQL 服务器版本相对应的手册,了解在 ':id' 附近使用的正确语法
I tried using a @ or ? instead of : and it does'nt work.
我尝试使用 @ 或 ? 而不是 : 它不起作用。
Thanks in advance for the help.
在此先感谢您的帮助。
