触发错误

Question

我无法为触发器解决此错误。怎么了？

CREATE OR REPLACE TRIGGER update_count
AFTER UPDATE ON form_data 
IS
BEGIN
   SET NOCOUNT ON;
   IF(UPDATE(januaryValue))  
       BEGIN
           UPDATE form_count C
           SET value = januaryValue
           FROM form_data D
           INNER JOIN form_count ON C.idData = D.idData;
       END;
   END IF; 
END;

我改变它并且我有另一个错误：第3行出错：PLS-00103：遇到符号＆＃34; BEGIN＆＃34;什么时候     期待以下之一：     ），*＆amp; = - +＆lt; /＆gt; at in mod mod not rem =＆gt;      ＆LT;＆GT;或！=或〜=＆gt; =＆lt; =＆lt;＆gt;或者喜欢喜欢2     like4 likec之间重叠||多星年的成员     SUBMULTISET

CREATE OR REPLACE TRIGGER update_count
AFTER UPDATE ON form_data 
FOR EACH ROW
BEGIN
IF(UPDATE(januaryValue))
       BEGIN
           UPDATE form_count 
           SET value = new.januaryValue
           WHERE idData = new.idData
       END; 
END IF; 

END
