Question

我正在尝试将我的发货日期分解为各种组件，以便我可以按照我需要的方式查询。我在Oracle查询中使用以下代码：

EXTRACT (DAY FROM "AR_TRX_HEADER"."SHIPDATETIME") AS DofM,
EXTRACT (YEAR FROM(ADD_MONTHS ("AR_TRX_HEADER"."SHIPDATETIME", 1))) AS FY,

我把YEAR拉得很好，但是每次尝试拉扯DAY时我都会收到错误。它告诉我，我错过了一个正确的括号。有什么想法吗？

任何帮助将不胜感激。谢谢！

这是整个查询（你会在这个查询中看到我一直把DayOfMonth作为一个字符字段 - 我现在正在重写它，试图把它作为一个数字。我只是修改了提取月来做那个它工作正常。我将在下一个财政季度工作。）：

Answer 1

使用以下查询测试chk

 select EXTRACT (DAY FROM to_date('24-june-2016')) AS DOFM ,TO_CHAR(to_date('24-june-2016'), 'Day') from dual;

然后尝试使用您的查询

select EXTRACT (DAY FROM "AR_TRX_HEADER"."SHIPDATETIME") AS DofM from your_table;

注意： - “AR_TRX_HEADER”。“SHIPDATETIME”应为日期类型，否则您需要转换为日期类型。

我能够让这个工作。它可能不是最有效的方法来完成它，但它确实有效，它给了我我需要的东西。谢谢你的输入。开始向他人解释一些内容总是有帮助的。它让你自己更多地思考。
