OAF實現客戶化查詢

在OAF中，存在標準的查詢面板，但是標準的查詢只能實現基礎、簡單的查詢，所以在真正的項目當中，一般情況下都是使用自己開發的客戶化查詢，開發客戶化查詢的一般步驟如下：

 

1. 建立頁面PG，修改Region

ID	PageLayoutRN
Region Style	PageLayout
AM Definition	RootAM
Window Title	xxx
Title	xxx

 

2. 在PageLayoutRN下建立Region，屬性如下：

ID	MessageComponentLayoutRN
Region Style	MessageComponentLayout
Width	100%
Rows	2
Columns	6

 

3. 在MessageComponentLayoutRN下新建搜索項（lov形式）

 

ID	SearchProject
Item Style	MessageLovInput
External LOV	XXX
Prompt	XXX

這裏的External LOV是來源於lov的region。

 

 

4.建立LOV的頁面，建立一個listOfValues的region

Region Style	ListOfValues
Scope	Public
AM Definition	LovAM

 

5. 基於vo，建立resultTable，ProjectId項的屬性

ID	ProjectId
Item Style	Formvalue

 

6. 在建立的lov組件下建立map映射

ID	ProjectNameMap
LOV Region Item	ProjectName
Return Item	SearchProject
Criteria Item	SerachProject

 

7.下拉框形式組件

ID	SearchProjectPhase
Item Style	MessageChoice
Picklist View Definition	cux.oracle.apps.pa.lov.server.ProjectPhaseVO
Picklist Display Attribute	ProjectStatusName
Picklist Value Attribute	ProjectStatusName
Prmpt

 

8. 建立ResultTable

Width

100%

 

9. 在messageComponentLayout Components下添加footer，在region下添加query按鈕

ID	Query
Item Style	SubmitButton
Prompt	搜索(&S)

10．繼續添加SpaceBean

ID	SpacerBean
Item Style	Spacer
Width	5

11. 繼續添加cancel按鈕

ID	Cancel
Item Style	SubmitButton
Disable Client Side Validation	True
Prompt	清除(&C)

上面的步驟是建立好一個搜索面板，下面編寫搜索邏輯代碼。

 

首先在co中捕捉點擊搜索按鈕的事件：

public void processFormRequest(OAPageContext pageContext, OAWebBean webBean) { super.processFormRequest(pageContext, webBean); OAApplicationModule am = pageContext.getApplicationModule(webBean); if (pageContext.getParameter("Cancel") != null) { String[] webBeanNames = { "SearchProject", "SearchCustomer", "SearchAreaCode", "SearchWindCode", "SearchMachineModel", "SearchProjectPhase", "SearchReportStartDate", "SearchReportEndDate", "SearchProjectManager", "SearchProjectId", "SearchPartyId" }; WebBeanUtil.resetWebBean(pageContext, webBean, webBeanNames); } else if (pageContext.getParameter("Query") != null) { String searchProjectId = pageContext.getParameter("SearchProjectId"); String searchPartyId = pageContext.getParameter("SearchPartyId"); String searchAreaCode = pageContext.getParameter("SearchAreaCode"); String searchWindCode = pageContext.getParameter("SearchWindCode"); String searchMachineModel = pageContext.getParameter("SearchMachineModel"); String searchProjectPhase = pageContext.getParameter("SearchProjectPhase"); Date searchReportStartDate = DateUtil.toDate(pageContext, pageContext.getParameter("SearchReportStartDate")); Date searchReportEndDate = DateUtil.toDate(pageContext, pageContext.getParameter("SearchReportEndDate")); String searchProjectManager = pageContext.getParameter("SearchProjectManager"); Serializable[] params = { searchProjectId, searchPartyId, searchAreaCode, searchWindCode, searchMachineModel, searchProjectPhase, searchReportStartDate, searchReportEndDate, searchProjectManager }; Class[] classes = { String.class, String.class, String.class, String.class, String.class, String.class, Date.class, Date.class, String.class }; am.invokeMethod("queryStatusReport", params, classes); } }

搜索邏輯代碼：

public void queryStatusReport(String searchProjectId, String searchPartyId, String searchAreaCode, String searchWindCode, String searchMachineModel, String searchProjectPhase, Date searchReportStartDate, Date searchReportEndDate, String searchProjectManager) { StatusReportVOImpl vo = getStatusReportVO1(); vo.setWhereClause(null); vo.setWhereClauseParams(null); int bindCount = 0; StringBuffer whereClause =new StringBuffer(400); whereClause.append(" 1=1"); Vector params = new Vector(9); if (searchProjectId!=null && !("".equals(searchProjectId))){ whereClause.append(" AND project_id = :"); whereClause.append(++bindCount); params.addElement(searchProjectId); } if (searchPartyId!=null && !("".equals(searchPartyId))){ whereClause.append(" AND party_id = :"); whereClause.append(++bindCount); params.addElement(searchPartyId); } if (searchAreaCode!=null && !("".equals(searchAreaCode))){ whereClause.append(" AND area_code = :"); whereClause.append(++bindCount); params.addElement(searchAreaCode); } if (searchWindCode!=null && !("".equals(searchWindCode))){ whereClause.append(" AND wind_code = :"); whereClause.append(++bindCount); params.addElement(searchWindCode); } if (searchMachineModel!=null && !("".equals(searchMachineModel))){ whereClause.append(" AND cux_pa_util_pkg.get_pa_machine_model(project_id,:"); whereClause.append(++bindCount); whereClause.append(") = 'Y'"); params.addElement(searchMachineModel); } if (searchProjectPhase!=null && !("".equals(searchProjectPhase))){ whereClause.append(" AND current_phase_name = :"); whereClause.append(++bindCount); params.addElement(searchProjectPhase); } if (searchReportStartDate!=null && !("".equals(searchReportStartDate))){ whereClause.append(" AND report_start_date >= :"); whereClause.append(++bindCount); params.addElement(searchReportStartDate); } if (searchReportEndDate!=null && !("".equals(searchReportEndDate))){ whereClause.append(" AND report_start_date <= :"); whereClause.append(++bindCount); params.addElement(searchReportEndDate); } if (searchProjectManager!=null && !("".equals(searchProjectManager))){ whereClause.append(" AND project_manager = :"); whereClause.append(++bindCount); params.addElement(searchProjectManager); } if (bindCount >0){ vo.setWhereClause(whereClause.toString()); Object[] bindParams = new Object[bindCount]; params.copyInto(bindParams); vo.setWhereClauseParams(bindParams); } vo.executeQuery(); }

 

結果如下
