BIRT（maximo data）：在脚本化数据集中重载了fetch脚本

Question

我继承了BIRT .rptdesign，它没有在＆＃34;预览结果中返回任何记录。＆＃34;涉及一个打开的脚本，以及一个fetch脚本，其中包含大约5个以上的sql查询。我为解决方案尝试的大部分内容涉及将fetch脚本中涉及的这些查询分解为它们自己的dataSet，然后将它们与开放脚本相关联（或者我尝试形成联合数据集，没有运气）。即使从fetch脚本中取出一个小查询，我也无法在结果预览中生成记录。我尝试上传了布局的图片，但没有这样做的声誉...如果您需要设计文件来帮助我看到所有内容都落地的地方，请告诉我们。

打开脚本：

maximoDataSet = MXReportDataSetProvider.create(this.getDataSource().getName(), this.getName());
maximoDataSet.open();

var sqlText = new String();
var printed = params["Printed"].toUpperCase().replace("Y","1");
var printed1 = printed.replace("N","0");
var where = new String(params["where"]);

if (params["Printed"].value)
    where += " and workorder.em_printed = '" + printed1 + "' "; 

// Add query to sqlText variable.
sqlText = "select workorder.wonum, workorder.workorderid as workorderid1, (select min(w2.workorderid) from maximo.workorder w2 where w2.istask=1 and w2.parent=workorder.wonum and w2.siteid=workorder.siteid) as workorderid, "
+ " workorder.pmnum as pmnum, workorder.targstartdate, workorder.siteid, workorder.description as wdesc, workorder.worktype, a.assetnum, a.description as adesc, a.em_relaymajor, a.em_relayminor, "
+ " workorder.location, l.description as ldesc, a.em_circuit, a.em_manfmodl, a.serialnum, j.em_craft, a.assetuid, "
+ " (select al.description from alndomain al where al.value=j.em_craft and al.domainid='EM_CRAFT') as cdesc, "
+ " (select wt.wtypedesc from maximo.worktype wt where wt.worktype=workorder.worktype) as wtdesc "
+ " from maximo.workorder "
+ " left outer join maximo.asset as a on a.assetnum=workorder.assetnum and a.siteid=workorder.siteid "
+ " left outer join maximo.jobplan as j on j.jpnum=workorder.jpnum and j.pluscrevnum=workorder.pluscjprevnum "
+ " left outer join maximo.locations as l on l.location=workorder.location and l.siteid=workorder.siteid"
// Include the Maximo where clause
+ " where workorder.istask=0 and workorder.status='INPRG' and workorder.siteid='EM' and " + where
;

maximoDataSet.setQuery(sqlText);

获取脚本：

if (!maximoDataSet.fetch())
    return (false);

// The specific get method should match the data type of the output column.
