Question

我想计算postfix smtp服务器的别名用法。使用virtual_alias_maps中的后缀指令“main.cf”通过MySQL查询别名。

user = user
password = pwd
hosts = 127.0.0.1
dbname = dbname
query = SELECT destination FROM view_aliases WHERE email='%s'

查找工作顺利，没有什么可抱怨的。我现在需要的是，在postfix查找别名的任何时候增加一个计数器（MySQL表中的列）。我试图将查询链接起来：

query = UPDATE view_aliases SET hitcount = hitcount+1 WHERE email='%s'; SELECT destination FROM view_aliases WHERE email='%s'

但是这会导致错误消息和后缀的查找问题：

Mar  7 11:04:01 host postfix/trivial-rewrite[32546]: warning: mysql query failed: 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 'SELECT destination FROM view_aliases WHERE email='mydomain.com'' at line 1

有没有办法像我需要的那样为postfix别名用法创建一个hitcounter？

更新：根据ethrbunny的提示，我尝试编写以下程序（这次是在测试数据库中）：

DELIMITER & 
CREATE PROCEDURE mailbox(IN recipient VARCHAR(255)) 
BEGIN
    SELECT * FROM test WHERE email=recipient; 
    UPDATE test SET value=value+1 WHERE email=recipient; 
END & 
DELIMITER ;

当我用CALL mailbox('test@test.com')调用该过程时，我收到来自服务器的Thread stack overrun错误消息...
