我想在后台创建一个报告定义项目，它将检索一些列。查询需要像这样才能检索我需要的内容：

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

，并且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} 列进行此灵活搜索查询，以在报告定义中搜索空值？

嗨，如果您想让报告定义参数化，这是可能的。

您可以通过以下步骤进行操作。

        </itemtype>

这里baseStoreParam,orderStartDateParam,orderEndDateParam是参数。

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

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);
