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？ 要么 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;
}

这不是要求开发人员具有许可的RAS SDK吗？
无论如何，只要使用我的CR开发者许可证，该软件都可以在AFAICT上使用，非常好。 我确实对其做了一些修改以使用StringBuilder等，如下所示... 也是
呈现RPT SummaryInfo对象中的数据
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);
// }
//}

var sb = new StringBuilder();
sb.AppendLine();
sb.AppendLine("---------- Summary -----------");
sb.AppendLine($@"Report source: {rptSourceName}");
sb.AppendLine($"Title: {reportSummary.ReportTitle}");
sb.AppendLine($"Subject: {reportSummary.ReportSubject}");
sb.AppendLine($"Comments: {reportSummary.ReportComments}");
sb.AppendLine($"Author: {reportSummary.ReportAuthor}");
sb.AppendLine($"Keywords: {reportSummary.KeywordsInReport}");
sb.AppendLine($"Last Saved By: {reportSummary.LastSavedBy}");
sb.AppendLine($"Revision #: {reportSummary.RevisionNumber}");
sb.AppendLine("------------------------------");
for (var i = 0; i < boDatabase.Tables.Count; i++)
{
ISCRTable tableObject = boDatabase.Tables[i];
if (tableObject.ClassName == "CrystalReports.Table")
{
sb.AppendLine(@"Table " + i + ": " + tableObject.Name);
}
else
{
boCommandTable = (CrystalDecisions.ReportAppServer.DataDefModel.CommandTable)boDatabase.Tables[i];
sb.AppendLine(@"Query " + i + ": " + boCommandTable.CommandText);
}
}
sb.AppendLine("------------------------------");
sb.AppendLine("");
sb.AppendLine("--------- Subreports ---------");
foreach (string subName in boReportClientDocument.SubreportController.GetSubreportNames())
{
SubreportClientDocument subRcd = boReportClientDocument.SubreportController.GetSubreport(subName);
sb.AppendLine($@"Subreport object: {subRcd.Name}");
sb.AppendLine("------------------------------");
for (var i = 0; i < boDatabase.Tables.Count; i++)
{

}
else
{

sb.AppendLine(@"Query " + i + ": " + boCommandTable.CommandText);
}
//sql += Environment.NewLine;
}
}
Log?.Debug($@"Report contents: { sb.ToString()}");
}
catch (Exception ex)
{
Log?.Error(ex);
throw;
}
}
生成：
