【问题描述】：

您能帮我找出存储过程中的错误吗？谢谢！！！

创建过程 realiza_tracking_primer_lectura ( 在 v_campaign_id int(11) 中，在 v_ares_emails_id int(11) 中，在 v_userid int(11) 中，在 v_country varchar(2) 中，在 v_ip varchar(15) 中，在 v_useragent varchar(255) 中，在 v_time int(11)) 开始 DECLARE ReadBefore int DEFAULT null; 如果 v_campaign_id 为 Null 则 SELECT userid FROM tracking_lecturas WHERE ares_emails_id = v_ares_emails_id and userid = v_userid into ReadBefore; 别的 SELECT userid FROM tracking_lecturas WHERE campaign_id = v_campaign_id and userid = v_userid into ReadBefore；万一; 如果 ReadBefore 为 Null 则插入 tracking_lecturas (campaign_id, ares_emails_id, userid, ip, useragent, timestamp) 值 (v_campaign_id, v_ares_emails_id, v_userid, v_ip, v_useragent, v_time); 万一; 结尾分隔符；

请分享您遇到的错误 - 无法编译？编译但运行时错误？运行但结果不正确？
运行或编译出错？

试试这个：

-- Dumping structure for procedure test.realiza_tracking_primer_lectura
DROP PROCEDURE IF EXISTS `realiza_tracking_primer_lectura`;
DELIMITER //
CREATE PROCEDURE `realiza_tracking_primer_lectura`(IN `v_campaign_id` int(11),IN `v_ares_emails_id` int(11),IN `v_userid` int(11),IN `v_country` varchar(2),IN `v_ip` varchar(15),IN `v_useragent` varchar(255),IN `v_time` int(11))
BEGIN
    #Routine body goes here...
        DECLARE ReadBefore int DEFAULT null;
        if v_campaign_id is Null then
            SELECT userid FROM tracking_lecturas WHERE ares_emails_id = v_ares_emails_id and userid = v_userid into ReadBefore;
         Else
            SELECT userid FROM tracking_lecturas WHERE campaign_id = v_campaign_id and userid = v_userid into ReadBefore;
         end if;

         if ReadBefore is Null then
            insert into tracking_lecturas (campaign_id, ares_emails_id, userid, ip, useragent, timestamp) values (v_campaign_id, v_ares_emails_id, v_userid, v_ip, v_useragent, v_time);
        end if;

END//
DELIMITER ;

【解决方案2】：

在CREATE PROCEDURE 之前缺少分隔符定义DELIMITER //。还需要通过在END 前面添加// 来终止程序，如下所示：

DELIMITER // -- define your delimiter here
CREATE PROCEDURE 
        realiza_tracking_primer_lectura (
        in v_campaign_id int(11), 
        in v_ares_emails_id int(11), 
        in v_userid int(11), 
        in v_country varchar(2),
        in v_ip varchar(15),
        in v_useragent varchar(255),
        in v_time int(11)) 
        BEGIN
            DECLARE ReadBefore int DEFAULT null;
            if v_campaign_id is Null then
                SELECT userid FROM tracking_lecturas WHERE ares_emails_id = 
                v_ares_emails_id and userid = v_userid into ReadBefore;
            Else
                SELECT userid FROM tracking_lecturas WHERE campaign_id = v_campaign_id and userid = v_userid into ReadBefore;
            end if;

            if ReadBefore is Null then
            insert into tracking_lecturas (campaign_id, ares_emails_id, userid, ip, useragent, timestamp) values (v_campaign_id, v_ares_emails_id, v_userid, v_ip, v_useragent, v_time);
            end if;

        END // -- terminate the procedure
DELIMITER ; -- revert to default delimiter
