Question

I would like to extract the SQL queries from Crystal Report .rpt files, is there a way to do this?

I don\'t have any of the Crystal Reports products, just the .rpt files

Answer 1

JoshL's answer worked for several of my reports, but not all of them. The following method, using ReportClientDocument.RowsetController.GetSQLStatement, was able to extract some of the queries that the other method missed.

foreach (string file in Directory.GetFiles("c:\\projects\\Reports", "*.rpt"))
{
    Console.WriteLine(String.Format("Processing {0}...", file));
    var doc = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
    doc.Load(file);

    var controller = doc.ReportClientDocument.RowsetController;

    var groupPath = new CrystalDecisions.ReportAppServer.DataDefModel.GroupPath();
    string temp = String.Empty;
    string commandSql = controller.GetSQLStatement(groupPath, out temp);
    //TODO: do something with commandSql
}

In "Crystal Reports ActiveX Designer Design and Runtime Library" (craxddrt.dll), the Report.SQLQueryString property will do what you want.

I can't seem to find an equivalent property in the .Net SDK, and believe me, I've been looking.

** edit **

It appears that one can make use of the In-Process RAS Server to get this information:

CrystalDecisions.ReportAppServer.DataDefModel.CommandTableClass.CommandText

Answer 3

In the Visual studio, select the .rpt file and Go to field explorer, right click on DatabaseFields. Click on SQL query option to view the query.

Answer 4

Here's a .Net example of code that grabs the Command Sql from all Crystal Reports in a given directory. It requires the Crystal 2008 .Net SDK to be installed (you can download a trial from SAP):

foreach (string file in Directory.GetFiles("c:\\projects\\Reports", "*.rpt"))
{
    Console.WriteLine(String.Format("Processing {0}...", file));
    var doc = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
    doc.Load(file);

    foreach (dynamic table in doc.ReportClientDocument.DatabaseController.Database.Tables)
    {
        if (table.ClassName == "CrystalReports.CommandTable")
        {
            string commandSql = table.CommandText;

            //TODO: do something with commandSql
        }
    }
}

To get the SQL as Crystal would build it when running a report, see this link: SAP Note 1280515 - How to extract SQL query from Crystal reports using RAS sdk.

I believe to do this, you need to supply the report parameter values so that Crystal can connect to the database in order to build the SQL. In the example, since a Report Viewer control is used, Crystal can prompt the user for the parameters.

My experience is with older versions of Crystal (8,9) - I've no idea what the file formats look like for more recent versions. However, it's worth opening the files up in a text editor just in case, but for the file formats I've seen, the query text is not accessible this way.

If I remember correctly, some versions of Visual Studio 2003 came with tools for manipulating Crystal .rpt files (but I guess this isn't of much use to you, since if you had this already, you wouldn't be asking!).

It's not a very imaginative suggestion, but perhaps your quickest route would be to download the 30-day trial version of the current Crystal Reports, and see if that will open the files for you.

Answer 6

The other way around this is if you can run the reports, you can hook up SQL Profiler to your DB and capture the incoming SQL on the database side.
