在oracle中可以使用这个'INSERT INTO'语句吗？

Question

INSERT INTO PHOENIX_AUDITTRAIL SET
audit_module = 'Location Master',
audit_message = 'Delete location',
datecreated = NOW(),
author = '".$_SESSION['username']."',
status = '".ADT_NOTICE."';

Answer 1

不，这句话的标准方法是：

INSERT INTO PHOENIX_AUDITTRAIL(audit_module, audit_message, datecreated, author, status)
    select 'Location Master', 'Delete location', NOW(), '".$_SESSION['username']."', '".ADT_NOTICE."'
    from dual

但是，在Oracle中，我认为您将使用sysdate而不是now()：

INSERT INTO PHOENIX_AUDITTRAIL(audit_module, audit_message, datecreated, author, status)
    select 'Location Master', 'Delete location', sysdate, '".$_SESSION['username']."', '".ADT_NOTICE."'
    from dual

除日期变量和from dual外，这是标准的SQL语法。
