mysql - 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。我尝试使用 PHPMyAdmin 或直接从 MySQL 客户端运行查询。

错误如下:

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 '' at line 5

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 ;

您是否尝试过 ELSE IF 而不是 ELSE IF？

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
