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.
