I have this:

This is on chars_insert, before. 

BEGIN
    IF EXISTS (SELECT * FROM chars WHERE accid = NEW.accid)
    BEGIN
            INSERT INTO `char_vars` SET `charid = NEW.charid, `varname` = `NotFirstChar`, `value` = 1;
    END

    INSERT INTO `char_equip`     SET `charid` = NEW.charid;
    INSERT INTO `char_exp`       SET `charid` = NEW.charid;
    INSERT INTO `char_jobs`      SET `charid` = NEW.charid;
    INSERT INTO `char_pet`  SET `charid` = NEW.charid;
    INSERT INTO `char_points`    SET `charid` = NEW.charid;
    INSERT INTO `char_profile`   SET `charid` = NEW.charid;
    INSERT INTO `char_storage`   SET `charid` = NEW.charid;
    INSERT INTO `char_inventory` SET `charid` = NEW.charid;
END

I had just added the IF EXISTS part...which broke the trigger. I am trying to find if one accountid has a character already and if they do, add a variable to the created character saying that this is not their first one. It says the error is on the IF EXISTS line, but I see no error...help please?

尝试以以下方式为 MySQL 更改代码：

BEGIN
    IF EXISTS (SELECT * FROM chars WHERE accid = NEW.accid) THEN
            INSERT INTO `char_vars` SET `charid` = NEW.charid, `varname` = `NotFirstChar`, `value` = 1;
    END IF;

    INSERT INTO `char_equip`     SET `charid` = NEW.charid;
    INSERT INTO `char_exp`       SET `charid` = NEW.charid;
    INSERT INTO `char_jobs`      SET `charid` = NEW.charid;
    INSERT INTO `char_pet`  SET `charid` = NEW.charid;
    INSERT INTO `char_points`    SET `charid` = NEW.charid;
    INSERT INTO `char_profile`   SET `charid` = NEW.charid;
    INSERT INTO `char_storage`   SET `charid` = NEW.charid;
    INSERT INTO `char_inventory` SET `charid` = NEW.charid;
END

此外，如果您NotFirstChars打算成为一个常量字符串（不是字段名称），您应该更改引号：'NotFirstChars'
