如何獲取Crystal報告所有查詢

Question

我的項目中有24個數據庫。一個數據庫已被分離到另外3個數據庫。現在，我必須更改Crystal Report的所有查詢。

如何通過C＃批量更新所有查詢？可能嗎？ 或 如何找出需要更改的問題？

私人字符串getSQL（遍歷infoObject IObject提取，EnterpriseSession eSession） { CrystalDecisions.CrystalReports.Engine.ReportDocument boReportDocument =新CrystalDecisions.CrystalReports.Engine.ReportDocument（）; CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument boReportClientDocument; CrystalDecisions.ReportAppServer.Controllers.DataDefController boDataDefController; CrystalDecisions.ReportAppServer.DataDefModel.Database boDatabase; CrystalDecisions.ReportAppServer.DataDefModel.CommandTable boCommandTable;

 // Load the report using the CR .NET SDK and get a handle on the ReportClientDocument 
     boReportDocument.Load(iObject,eSession); 
     boReportClientDocument = boReportDocument.ReportClientDocument; 

     // Use the DataDefController to access the database and the command table. 
     // Then display the current command table SQL in the textbox. 
     boDataDefController = boReportClientDocument.DataDefController; 
     boDatabase = boDataDefController.Database; 

     string sql; 
     sql = ""; 

     for (int i = 0; i < boDatabase.Tables.Count; i++) 
     { 
      CrystalDecisions.ReportAppServer.DataDefModel.ISCRTable tableObject = boDatabase.Tables[i]; 

      if (tableObject.ClassName == "CrystalReports.Table") 
      { 
       sql = sql + "Table " + i + ": " + tableObject.Name; 
      } 
      else 
      { 
       boCommandTable = (CrystalDecisions.ReportAppServer.DataDefModel.CommandTable)boDatabase.Tables[i]; 
       sql = sql + "Query " + i + ": " + boCommandTable.CommandText; 
      } 
      sql += Environment.NewLine; 

     } 

     foreach (string subName in boReportClientDocument.SubreportController.GetSubreportNames()) 
     { 
      CrystalDecisions.ReportAppServer.Controllers.SubreportClientDocument subRCD = boReportClientDocument.SubreportController.GetSubreport(subName); 

      for (int i = 0; i < boDatabase.Tables.Count; i++) 
      { 
       CrystalDecisions.ReportAppServer.DataDefModel.ISCRTable tableObject = boDatabase.Tables[i]; 

       if (tableObject.ClassName == "CrystalReports.Table") 
       { 
        sql = sql + "Table " + i + ": " + tableObject.Name; 
       } 
       else 
       { 
        boCommandTable = (CrystalDecisions.ReportAppServer.DataDefModel.CommandTable)subRCD.DatabaseController.Database.Tables[i]; 
        sql = sql + "Subreport " + subName + " - Query " + i + ": " + boCommandTable.CommandText; 
       } 
       sql += Environment.NewLine; 
      } 

     } 


     // Clean up 
     return sql; 

    }
