http://www.egbolig.dk/drift_bo_syd.rpt (HERE IS THE REPORT)
We are using SAP Crystal Report .NET Runtime files (http://scn.sap.com/docs/DOC-7824 newest version 13.0.9.1312) in our web asp.net application. Everything have been working fine, but we have can into problems when showing the certain kinda reports.
In our code get the reports sql statement using getSQLStatement.
Dim gp As New GroupPath() Dim sql As String = report.ReportClientDocument.RowsetController.GetSQLStatement(gp)
This will get the sql, and we use this sql (getSqlStatement) and attach a sql WHERE clause from the code to only get a certain number of records.
The report Drift_bo_syd.rpt has 5 tables, and the following sql statement.
Database/Show Sql Statement
SELECT "rekvstam"."Sel", "rekvstam"."Afd", "rekvstam"."Levadresse", "rekvstam"."Rekvisition", "rekvstam"."Lejemaal", "rekvstam"."Lejer", "rekvstam"."Udfoertaf", "rekvstam"."Udfoertdato", "rekvstam"."Krit", "Selskab"."Adresse", "Selskab"."Postby", "Selskab"."Tlf", "Selskab"."Fax", "rekvstam"."Kontor", "rekvstam"."Hjemme", "rekvstam"."Rekvdato", "rekvstam"."Aftale", "rekvstam"."InitialRet", "rekvstam"."Arbejde", "kreditor"."Att", "rekvstam"."Konto", "Selskab"."Navn", "Selskab"."Email", "Interessentadresse"."Navn", "Interessentadresse"."Adresse", "Interessentadresse"."Postby", "Interessentadresse"."Email1", "Interessentadresse"."Telefon_Fax", "Interessentadresse"."Type", "Interessentadresse"."Tlf1", "rekvstam"."tlfLejer", "kreditor"."Kred", "Interessentadresse"."Interessentnr" FROM (("Rekvstam" "rekvstam" INNER JOIN "Selskab" "Selskab" ON "rekvstam"."Sel"="Selskab"."Sel") LEFT OUTER JOIN "Kreditor" "kreditor" ON "rekvstam"."Kred"="kreditor"."Kred") INNER JOIN "Interessentadresse" "Interessentadresse" ON "kreditor"."Interessentnr"="Interessentadresse"."Interessentnr" WHERE "Interessentadresse"."Type"='K'
But if we run the report from our asp.net code, we get the following error:
Cannot determine the queries necessary to get data for this report. Failed to retrieve data from the database. Error in File Drift_Bo_Syd {97FED382-1BAC-4DB1-970F-9E098ECE28F1}.rpt: Failed to retrieve data from the database.
After a long time searching for a solution, we found out that if we place the column kred from the kreditor table on the report, the report will work. (field explorer / database fields / kreditor (table) / kred (column)
Very important is that the field "kreditor.kred" is a primary key of the table kreditor, and also used in the linking.!
(We can get the report to work if we call the sql statement with the "kreditor"."kred" in the SELECT statement.
SELECT "kreditor"."kred", "rekvstam"."Sel", "rekvstam"."Afd", "rekvstam"."Levadresse", "rekvstam"."Rekvisition", "rekvstam"."Lejemaal", "rekvstam"."Lejer", "rekvstam"."Udfoertaf", "rekvstam"."Udfoertdato", "rekvstam"."Krit", "Selskab"."Adresse", "Selskab"."Postby", "Selskab"."Tlf", "Selskab"."Fax", "rekvstam"."Kontor", "rekvstam"."Hjemme", "rekvstam"."Rekvdato", "rekvstam"."Aftale", "rekvstam"."InitialRet", "rekvstam"."Arbejde", "kreditor"."Att", "rekvstam"."Konto", "Selskab"."Navn", "Selskab"."Email", "Interessentadresse"."Navn", "Interessentadresse"."Adresse", "Interessentadresse"."Postby", "Interessentadresse"."Email1", "Interessentadresse"."Telefon_Fax", "Interessentadresse"."Type", "Interessentadresse"."Tlf1", "rekvstam"."tlfLejer", "kreditor"."Kred", "Interessentadresse"."Interessentnr" FROM (("Rekvstam" "rekvstam" INNER JOIN "Selskab" "Selskab" ON "rekvstam"."Sel"="Selskab"."Sel") LEFT OUTER JOIN "Kreditor" "kreditor" ON "rekvstam"."Kred"="kreditor"."Kred") INNER JOIN "Interessentadresse" "Interessentadresse" ON "kreditor"."Interessentnr"="Interessentadresse"."Interessentnr" WHERE "Interessentadresse"."Type"='K'
But it should not be necessary to include this field (which is the primary key and used in linking the report) in the sql statement,
BECAUSE it is not used in the report. So maybe this is a bug?
It has not been necessary in RDC Crystal Report or RAS Crystal Report in a classic asp envoriment.
Here is the code we use to set the reports SQL Statement)
Try
Dim conn As New SqlConnection(connString)
conn.Open()
Dim sd As New SqlDataAdapter(New SqlCommand(nySQL, conn))
Dim ds As New Data.DataSet()
Dim navn As String = report.Database.Tables.Item(0).Name
sd.Fill(ds, navn)
report.SetDataSource(ds)
conn.Close()
Catch ex As Exception
Throw
End Try
