PeopleSoft 查询管理器表达式

Question

使用 Microsoft SQL 服务器，我正在尝试将 A.CHECK_DT 格式化为 mmddyyyy - 带有前导零，因此今年的 1 月 11 日看起来像：01112019。 麻烦的是我尝试的一切都不对。我最接近改变格式的是：

CONCAT(MONTH((CONVERT(CHAR(10),A.CHECK_DT,101))),DAY((CONVERT(CHAR(10),A.CHECK_DT,101))),YEAR((CONVERT(CHAR(10),A.CHECK_DT,101))))

但这会将日期转换为 1182019，没有前导零。有人有什么想法吗？

[edit] 下面的评论适用于 Oracle 数据库，但事实证明这个问题是针对 Microsoft SQL 服务器的。我将留下答案，以防它对通过搜索找到此问题的其他人有用。

Assuming you are on oracle, try using an additional parameter on the TO_CHAR function to tell it how you want to format the output.

You can format the date using TO_CHAR. the syntax is something like TO_CHAR(YOURDATE,YOURFORMAT). And for your specific example, it would be TO_CHAR(A.CHECK_DT,'MMDDYYYY')

Here is a web page that shows this SQL as a working query:

• http://sqlfiddle.com/#!4/f2c01/3

Here are some good resources I found by searching for: Oracle TO_CHAR:

• https://www.techonthenet.com/oracle/functions/to_char.php

• http://psoug.org/definition/TO_CHAR.htm

• http://www.dba-oracle.com/f_to_char_sql.htm

And of course, there is always Oracle documentation (although it tends to have fewer examples):

• https://docs.oracle.com/cd/B19306_01/server.102/b14200/functions180.htm

• https://docs.oracle.com/cd/B19306_01/server.102/b14200/sql_elements004.htm#i34510

Answer 2

我想通了：

此脚本将为您提供格式为 MMDDYYYY

替换(CONVERT(VARCHAR(10), CAST(A.CHECK_DT AS DATE), 101),'/','')

(表达式类型 = 字符，长度 10)
