如何仅在 App Engine PeopleCode 的日期时间字段中评估日期

Question

首先我想说我是 PeopleSoft AppEngine 和 PeopleCode 开发的新手。

我在 PeopleSoft App Engine 程序中执行以下步骤（OnExecute 步骤），该程序检索 table 中的记录，然后获取这些现有值并使用新的商品价格创建新行。

程序正在执行 table 'PS_ITM_VNDR_UOM_PR' 中的 SQLExec 语句，并使用 EFFDT 作为 WHERE 子句标准的一部分。对于 EFFDT，它正在填充变量值，格式为 'YYYY-MM-DD'。问题是 table PS_ITM_VNDR_UOM_PR 中的某些行对于 EFFDT 具有日期和时间：（即 2018-03-19 10:04:03.040），而不仅仅是日期默认空白时间：（即 2018-03-16 00:00:00.000）。

这是另一种看待问题的方式，这是 SQL 程序是运行，它的结果是：

SQL 在 WHERE 子句中使用标准 EFFDT 的代码/结果（不选取任何行）：

与 EFFDT 日期转换逻辑相同的 SQL 代码/结果（选取一行）：

有没有办法修改代码中的 SQL 语句，类似于我在上面的本机 SQL 服务器中所做的，或者我可以定义一个仅日期程序变量的方法我可以在 SQLExec code?

中使用

我在下面的代码中发表了评论，我认为该行包含需要修改的 SQL 语句。

非常感谢您提供的任何意见！

Answer 1

如果这是一个 Oracle 数据库，您也许可以在 EFFDT 字段上使用 TRUNC。

...UNIT_OF_MEASURE = :4 AND TRUNC(EFFDT) = :5

不确定 SQLServer 或其他数据库上的等效项是什么。我认为那样会忽略时间而只是加入约会。尽管您随后可能会遇到返回多行的问题，或其他重复行问题。 EFFDT 字段通常不应包含时间组件，因此该环境可能存在数据问题。

Answer 2

将 &MaxEffdt 定义为日期。

您已将其定义为字符串，但您 select 将日期放入其中，从而强制进行隐式转换。
