灵活搜索检查报告定义 Hybris

问题描述

我想在后台创建一个报告定义项，以检索一些列。查询需要像这样来检索我需要的内容：

SELECT {a},{b},{c} FROM {model} WHERE {d} IS NULL AND {e} IS NULL

所有值 (a,b...e) 都是字符串。我想参数化 {d} 和 {e} 列，但我希望能够准确搜索我之前编写的查询。 我开始做类似的事情：

SELECT {a},{c} FROM {model} WHERE {d}=?dStatus AND {e}=?eStatus

、dStatus 和 eStatus 参数是 java.lang.String 类型，但这不起作用。

是否可以使用参数化的 {d} 和 {e} 列进行这个灵活的搜索查询，以在报告定义中搜索空值？

解决方法

嗨，如果您想将报告定义参数化，这是可能的。

您可以通过以下步骤来完成。

这里baseStoreParam,orderStartDateParam,orderEndDateParam是参数。

注意：根据预期的结果值和类型，我们需要在 <attributes> 标签中定义该属性的位置和类型。

您可以拆分原始查询及其条件

String query = "SELECT {a},{b},{c} FROM {model} WHERE {d} %s AND {e} %s";
String dStatusParam = "";
String eStatusParam = "";
if (null == dStatus) {
   dStatusParam = "IS NULL";
} else {
   dStatusParam = "= '" + dStatus + "'";
}
if (null == eStatus) {
   eStatusParam = "IS NULL";
} else {
   eStatusParam = "= '" + eStatus + "'";
}
query = String.format(query,dStatusParam,eStatusParam);
