在JasperReports中使用SQL“Where IN（val1，val2，val3）”

Question

我有一个Jasper报告，其中Where子句作为参数：

我传递的where子句是：

WHERE vw.computer_number IN ("12635, 34657, 35477")

当我在IReport中预览报表时，它返回所有3个页面，其中每个页面id =在IN（）中指定的computer_number。

但是当我在HashMap中将它作为参数传递时，它只返回带有第一个计算机编号的1页。

参数定义：

<parameter name="paySlipWhereClause" class="java.lang.String" isForPrompting="false"> 
  <defaultValueExpression>
    <![CDATA[" Where vw.computer_number IN(12635, 34657, 35477)"]]>
  </defaultValueExpression> 
</parameter>

构建参数值的Java代码：

String computer_numbers[] = {"12635", "34657", "3547"}; 
String computer_nos = ""; 
for (int i = 0; i < computer_numbers.length; i++) { 
  computer_nos = computer_nos + "," + computer_numbers[i]; 
} 
String comp_numbers = computer_nos.replaceFirst(",", ""); 
HashMap param = new java.util.HashMap<String, String>(); 
param.put("payroll_tag", payroll_tag); 
//" WHERE vw.computer_number IN (29875,31775,29929)" 
param.put("paySlipWhereClause", "WHERE vw.computer_number IN (" + comp_numbers + ")");
