Solved: Table Location Error Oracle and SqlServer

Former Member · ‎2010 Feb 09

I would like to use the same report for several data base providers (ODBC, OLEDB SqlServer and OLEDB Oracle).

My original report is designed with ODBC by another department. When I try to change the data base provider to Oracle or SqlServer I have an error at line:

<code>

 //this line throw an exception if the report was not designed with the

same database provider.

switch (provider)

{

case Provider.SqlServer:

        crTable.Location =

String.Format("{0}.dbo.", crConnectionInfo.DatabaseName, crTable.Name); //database.dbo.tablename         break;     case Provider.Oracle:         crTable.Location = String.Format(".", crConnectionInfo.DatabaseName, crTable.Name);

//schema.tablename

break;

default:

break;

}</code>

Even setting the same location, like this crTable.Location = crTable.Location; the code throws an exception.

I have to change the report schema location at runtime because we have several databases (SqlServer) or schemas (Oracle) and we have to use the same report.

I use Crystal Reports Version=12.0.2000.0

Here is my complete code:

<code>

private CrystalDecisions.Shared.ConnectionInfo FixDatabaseSqlServer()

{

CrystalDecisions.Shared.DbConnectionAttributes dbAttributes = new

DbConnectionAttributes();

dbAttributes.Collection.Set("Server", this.ServerName.Text);

dbAttributes.Collection.Set("Trusted_Connection", "false");

dbAttributes.Collection.Set("Data Source", this.ServerName.Text);

dbAttributes.Collection.Set("Initial Catalog", this.DatabaseName.Text);

dbAttributes.Collection.Set("Integrated Security", "false");

dbAttributes.Collection.Set("Provider", "SQLOLEDB");

//setup the connection

CrystalDecisions.Shared.ConnectionInfo crConnectionInfo = new ConnectionInfo();

crConnectionInfo.DatabaseName = this.DatabaseName.Text;

crConnectionInfo.ServerName = this.ServerName.Text;

crConnectionInfo.UserID = this.UserID.Text;

crConnectionInfo.Password = this.Password.Text;

crConnectionInfo.IntegratedSecurity = false;

crConnectionInfo.Attributes.Collection.Set("Database DLL", "crdb_ado.dll");

crConnectionInfo.Attributes.Collection.Set("QE_DatabaseName",

this.DatabaseName.Text);

crConnectionInfo.Attributes.Collection.Set("QE_DatabaseType", "OLE DB (ADO)");

crConnectionInfo.Attributes.Collection.Set("QE_LogonProperties", dbAttributes);

crConnectionInfo.Attributes.Collection.Set("QE_ServerDescription",

this.ServerName.Text);

crConnectionInfo.Attributes.Collection.Set("QE_SQLDB", "True");

crConnectionInfo.Attributes.Collection.Set("SSO Enabled", "False");

crConnectionInfo.Type = CrystalDecisions.Shared.ConnectionInfoType.CRQE;

crConnectionInfo.LogonProperties = dbAttributes.Collection;

return (crConnectionInfo);

}

private CrystalDecisions.Shared.ConnectionInfo FixDatabaseOracle()

{

CrystalDecisions.Shared.DbConnectionAttributes dbAttributes = new

DbConnectionAttributes();

dbAttributes.Collection.Set("Server", this.ServerName.Text);

dbAttributes.Collection.Set("Trusted_Connection", "False");

dbAttributes.Collection.Set("Data Source", this.ServerName.Text);

dbAttributes.Collection.Set("Provider", "MSDAORA");

//setup the connection

CrystalDecisions.Shared.ConnectionInfo crConnectionInfo = new ConnectionInfo();

crConnectionInfo.DatabaseName = "";

crConnectionInfo.ServerName = this.ServerName.Text;

crConnectionInfo.UserID = this.UserID.Text;

crConnectionInfo.Password = this.Password.Text;

crConnectionInfo.IntegratedSecurity = false;

crConnectionInfo.Attributes.Collection.Set("Database DLL", "crdb_oracle.dll");

crConnectionInfo.Attributes.Collection.Set("QE_DatabaseName", "");

crConnectionInfo.Attributes.Collection.Set("QE_DatabaseType", "OLE DB (ADO)");

crConnectionInfo.Attributes.Collection.Set("QE_LogonProperties", dbAttributes);

crConnectionInfo.Attributes.Collection.Set("QE_ServerDescription",

this.ServerName.Text);

crConnectionInfo.Attributes.Collection.Set("QE_SQLDB", "True");

crConnectionInfo.Attributes.Collection.Set("SSO Enabled", "False");

crConnectionInfo.Type = CrystalDecisions.Shared.ConnectionInfoType.CRQE;

crConnectionInfo.LogonProperties = dbAttributes.Collection;

return (crConnectionInfo);

}

private void FixDatabase(ReportDocument report, Provider provider)

{

bool setLocationError = false;

string tableLocationPattern = String.Empty;

CrystalDecisions.Shared.ConnectionInfo crConnectionInfo = null;

switch (provider)

{

case Provider.SqlServer:

crConnectionInfo = FixDatabaseSqlServer();

tableLocationPattern = String.Format("{0}..", crConnectionInfo.DatabaseName, ""); break; case Provider.Oracle: crConnectionInfo = FixDatabaseOracle(); tableLocationPattern = String.Format(".", crConnectionInfo.UserID, ""); break; case Provider.Undefinded: default: break; } //set database login information for the entire report object report.SetDatabaseLogon(crConnectionInfo.UserID, crConnectionInfo.Password, crConnectionInfo.ServerName, crConnectionInfo.DatabaseName); CrystalDecisions.CrystalReports.Engine.Database crDatabase = report.Database; //Set the CrDatabase Object to the Report's Database CrystalDecisions.CrystalReports.Engine.Tables crTables = crDatabase.Tables; //Set the CrTables object to the Tables collection of the Report's dDtabase foreach (CrystalDecisions.CrystalReports.Engine.Table crTable in crTables) { TableLogOnInfo crTableLogOnInfo = null; crTableLogOnInfo = crTable.LogOnInfo; if (crTableLogOnInfo != null) { crTableLogOnInfo.ConnectionInfo = crConnectionInfo; crTable.ApplyLogOnInfo(crTableLogOnInfo); // //Set location. // try { //this line throw an exception if the report was not designed with the same database provider. switch (provider) { case Provider.SqlServer: crTable.Location = String.Format(".dbo.", crConnectionInfo.DatabaseName, crTable.Name); //database.dbo.tablename break; case Provider.Oracle: crTable.Location = String.Format(".", crConnectionInfo.DatabaseName,

crTable.Name); //schema.tablename

break;

default:

break;

}

crTable.Location = crTable.Location;

}

catch (Exception ex)

{

setLocationError = true;

//throw;

}

crTable.TestConnectivity();

}

//call this method recursively for each subreport

foreach (ReportObject reportObject in report.ReportDefinition.ReportObjects)

{

if (reportObject.Kind == ReportObjectKind.SubreportObject)

{

FixDatabase(report.OpenSubreport(((SubreportObject)reportObject).SubreportName),

provider);

}

}

</code>

I tried everything I found at forums with no success.

Please, Is there anyone with the same problem who had solved it?

Is it possible to have the same report and several database providers?

What have do I have to do?

Thank you very much.

I am still struggling with a similar issue. Our large base of Crystal reports has been deployed to customers (since Crystal 4) with our own application system which resets the logon information to the customers' own database and user information. Our current deployment uses VS 2008, Crystal 11.5 runtime and CRAXDRT which we now understand is not supported with VS 2008.

We are trying to upgrade to Crystal 2008 and have successfully set logon information for ODBC and OLE DB references but have been unable to do some of the database relocation that we could previously in CRAXDRT. We have some reports that were able to be run both against an Access database or a SQL Server database. Is this still possible in the Crystal 2008 object model? If Inproc RAS is required, is that still freely distributable with the Crystal runtime? Is there any documentation that helps converting CRAXDRT code to the Crystal 2008 ReportDocument model? So far the only missing functionality I have found is the progress bar, but I worry about what's around the next corner in the conversion. Thanks for any help you can give.
