为什么 GETDATE() 是无效标识符

Why is the GETDATE() an invalid identifier says Oracle Sql Developer tool when I debug this code:

CREATE OR REPLACE TRIGGER SPName
AFTER UPDATE
ON TableName 
FOR EACH ROW
BEGIN
    UPDATE TableName SET LastModifiedDate = GETDATE() WHERE TableName.DET_ID = :new.DET_ID;
END;

推荐答案

我想你想要的是 SYSDATE，而不是 GETDATE().试试看:

UPDATE TableName SET LastModifiedDate = (SELECT SYSDATE FROM DUAL);
