使用MySQL触发语法错误

Question

我想在MySQL中创建触发器，但出现语法错误。 我试图用PHPMyAdmin或直接从MySQL Client运行查询。

这是错误：

1064-您的SQL语法有误； 检查与您的MySQL服务器版本相对应的手册以获取在第5行的''附近使用的正确语法

CREATE TRIGGER asterisk.bi_queueEvents BEFORE INSERT ON aasterisk.queue_log
FOR EACH ROW
BEGIN
IF (NEW.event = 'ADDMEMBER')THEN
INSERT INTO agent_status (agentId,agentStatus,timestamp,callid) VALUES (NEW.agent,'READY',FROM_UNIXTIME(NEW.time),NULL) ON DUPLICATE KEY UPDATE agentStatus = "READY", timestamp = FROM_UNIXTIME(NEW.time), callid = NULL;
ELSIF (NEW.event = 'REMOVEMEMBER')THEN
INSERT INTO agent_status (agentId,agentStatus,timestamp,callid) VALUES (NEW.agent,'LOGGEDOUT',FROM_UNIXTIME(NEW.time),NULL) ON DUPLICATE KEY UPDATE agentStatus = "LOGGEDOUT", timestamp = FROM_UNIXTIME(NEW.time), callid = NULL;
ELSIF (NEW.event = 'PAUSE')THEN
INSERT INTO agent_status (agentId,agentStatus,timestamp,callid) VALUES (NEW.agent,'PAUSE',FROM_UNIXTIME(NEW.time),NULL) ON DUPLICATE KEY UPDATE agentStatus = "PAUSE", timestamp = FROM_UNIXTIME(NEW.time), callid = NULL;
ELSIF (NEW.event = 'UNPAUSE')THEN
INSERT INTO agent_status (agentId,agentStatus,timestamp,callid) VALUES (NEW.agent,'READY',FROM_UNIXTIME(NEW.time),NULL) ON DUPLICATE KEY UPDATE agentStatus = "READY", timestamp = FROM_UNIXTIME(NEW.time), callid = NULL;
END IF;
END ;
//

Answer 1

您是否已尝试使用ELSIF代替ELSEIF？

IF(boolean_expression 1)THEN 
   S1; -- Executes when the boolean expression 1 is true 
ELSIF( boolean_expression 2) THEN
   S2;  -- Executes when the boolean expression 2 is true 

Answer 2

我找到了解决方案，这是一个很好的要求：

delimiter |
CREATE TRIGGER bi_queueEvents
BEFORE INSERT ON queue_log
FOR EACH ROW
BEGIN
    IF NEW.event = 'ADDMEMBER' THEN
        INSERT INTO agent_status (agentId,agentStatus,timestamp,callid)
        VALUES (NEW.agent,'READY',FROM_UNIXTIME(NEW.time),NULL) ON DUPLICATE KEY UPDATE agentStatus = "READY", timestamp = FROM_UNIXTIME(NEW.time), callid = NULL;
    ELSEIF NEW.event = 'REMOVEMEMBER' THEN
        INSERT INTO agent_status (agentId,agentStatus,timestamp,callid)
        VALUES (NEW.agent,'LOGGEDOUT',FROM_UNIXTIME(NEW.time),NULL) ON DUPLICATE KEY UPDATE agentStatus = "LOGGEDOUT", timestamp = FROM_UNIXTIME(NEW.time), callid = NULL;
    ELSEIF NEW.event = 'PAUSE' THEN
        INSERT INTO agent_status (agentId,agentStatus,timestamp,callid)
        VALUES (NEW.agent,'PAUSE',FROM_UNIXTIME(NEW.time),NULL) ON DUPLICATE KEY UPDATE agentStatus = "PAUSE", timestamp = FROM_UNIXTIME(NEW.time), callid = NULL;
    ELSEIF NEW.event = 'UNPAUSE' THEN
        INSERT INTO agent_status (agentId,agentStatus,timestamp,callid)
        VALUES (NEW.agent,'READY',FROM_UNIXTIME(NEW.time),NULL) ON DUPLICATE KEY UPDATE agentStatus = "READY", timestamp = FROM_UNIXTIME(NEW.time), callid = NULL;
    END IF;
END |
delimiter ;
