c# - 如何获取水晶报表所有查询

Question

我的项目中有 24 个数据库。一个数据库已分离到另外 3 个数据库。现在，我必须更改 Crystal Report 的所有查询。

如何通过 C# 批量更新所有查询？可能吗？或者我怎样才能找出需要改变的问题？

私有字符串 getSQL(InfoObject iObject, EnterpriseSession eSession) { CrystalDecisions.CrystalReports.Engine.ReportDocument boReportDocument = new 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;

    }

这不需要开发人员拥有许可的 RAS SDK 吗？

无论如何，这适用于我的 CR 开发人员许可证的 AFAICT，所以很好。
我确实对其进行了一些修改以使用 StringBuilder 等等，如下所示......还有

• 使用 log4net 转储查询...
• 显示从 (rptSourceName) 加载 RPT 的位置

• 显示来自 RPT SummaryInfo 对象的数据

    private void DumpQueries(CrystalDecisions.CrystalReports.Engine.ReportDocument doc, string rptSourceName)
  {
      try
      {
          //CrystalDecisions.CrystalReports.Engine.ReportDocument boReportDocument = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
  
          CommandTable boCommandTable;
          var boReportClientDocument = doc.ReportClientDocument;
          var boDataDefController = boReportClientDocument.DataDefController;
          var boDatabase = boDataDefController.Database;
  
          var reportSummary = doc.SummaryInfo;
          var reportName = doc.Name ?? doc.FileName;
  
          //return; // disabled for now.
  
          //foreach (dynamic table in doc.ReportClientDocument.DatabaseController.Database.Tables)
          //{
          //    if (table.ClassName == "CrystalReports.CommandTable")
          //    {
          //        string commandSql = table.CommandText;
  
          //        Log?.DebugFormat(@"Report object: {0} - SQL: {1}", doc.Name, commandSql);
          //    }
          //}
