Hello,
I have a dataset with three data tables. And my database is in MS Access. I fill all of them with separate OleDBDataAdapters. But when I run the windows form it returns empty crystall report. In fact when debugging, I see that the dataset is empty, all of the tables remain empty.
Here are the select strings that I use to fill the datatables:
1. For filling the first table "baraniotselect1" in the dataset I use this select
SELECT MAGACIN.GBR, [@data1] AS Datapoc, [@data2] AS Datakr, Sum(IIf([MAGACIN.SIFRA]="0992201",MAGACIN.KOL,0)) AS Addblue, Sum(IIf([MAGACIN.SIFRA]="0999001",MAGACIN.KOL,0)) AS Antifriz, Sum(IIf([MAGACIN.SIFRA]="0991000",MAGACIN.KOL,0)) AS Gorivo, Sum(IIf((([MAGACIN.SIFRA])="0993050" Or ([MAGACIN.SIFRA])="0993051"),MAGACIN.KOL,0)) AS Motmaslo, Round(((Sum(IIf(([MAGACIN.SIFRA]="0992201") And ([MAGACIN.DATA]>=[@data1]) And ([MAGACIN.DATA]<=[@data2]) And ([MAGACIN.GBR] Between [@gbr1] And [@gbr2]) And ((NOVI.AB)=[@ab1] or (NOVI.AB)=[@ab2]) ,[MAGACIN.KOL],0))/(Sum(IIf(([MAGACIN.SIFRA]="0991000") And ([MAGACIN.DATA]>=[@data1]) And ([MAGACIN.DATA]<=[@data2]) And ((NOVI.AB)=[@ab1] or (NOVI.AB)=[@ab2]),[MAGACIN.KOL],0))))*100),2) AS Addbluegor
FROM NOVI INNER JOIN MAGACIN ON NOVI.GBR = MAGACIN.GBR
WHERE (((MAGACIN.DATA) Between [@data1] And [@data2]) AND ((MAGACIN.GBR) Between [@gbr1] And [@gbr2]) AND ((NOVI.AB)=[@ab1] or (NOVI.AB)=[@ab2]) )
GROUP BY MAGACIN.GBR
HAVING ((Sum(IIf([MAGACIN.SIFRA]="0991000",[MAGACIN].[KOL],0))>0));
2. For filling the second table "PocKrajRazl" in the dataset I use:
SELECT NALOG1.GBRV, Min(IIf(([NALOG1.DATA]>=[@data1]) And ([NALOG1.DATA]<=[@data2]) And ([NALOG1].[POCKM]>0) And ([NALOG1.GBRV] Between [@gbr1] And [@gbr2]),[NALOG1.POCKM],Null)) AS pockm, Max(IIf(([NALOG1.DATA]>=[@data1]) And ([NALOG1.DATA]<=[@data2]) And ([NALOG1.GBRV] Between [@gbr1] And [@gbr2]),[NALOG1.KRAJKM],Null)) AS krajkm, (Max(IIf(([NALOG1.DATA]>=[@data1]) And ([NALOG1.DATA]<=[@data2]) And ([NALOG1.GBRV] Between [@gbr1] And [@gbr2]),[NALOG1.KRAJKM],Null))-Min(IIf(([NALOG1.DATA]>=[@data1]) And ([NALOG1.DATA]<=[@data2]) And ([NALOG1].[POCKM]>0),[NALOG1.POCKM],Null))) AS RAZLIKA, Max(NOVI.DATAP) AS Poslprov, Max(NOVI.DATAS) AS Poslserv, Sum(NALOG1.KM) AS SUMKM, IIf([SUMKM]>=(([NOVI].[KMS1]+[NOVI].[KMS2])-1000),"ZA SERVIS",
(IIf(Sum(NALOG1.KM)>=(([NOVI].[KMP1]+[NOVI].[KMP2])-1000),"PROVERKA",""))) AS Zabeleska
FROM NALOG1 INNER JOIN NOVI ON NALOG1.GBRV = NOVI.GBR
WHERE ((NOVI.AB)=[@ab1] or (NOVI.AB)=[@ab2]) AND ( (NALOG1.GBRV)>=[@gbr1] And (NALOG1.GBRV)<=[@gbr2] )
GROUP BY NALOG1.GBRV, NOVI.KMP1, NOVI.KMP2, NOVI.KMS1, NOVI.KMS2;
in my C# windows form.
And I use these selects i.e. tables to fill the third table with this select:
SELECT baraniotselect1.GBR, baraniotselect1.Datapoc, baraniotselect1.Datakr, baraniotselect1.Gorivo, PocKrajRazl.SUMKM, ROUND(((baraniotselect1.Gorivo/PocKrajRazl.SUMKM)*100),2) AS Prospotrgor, baraniotselect1.Addblue, baraniotselect1.Addbluegor, baraniotselect1.Antifriz, baraniotselect1.Motmaslo, PocKrajRazl.pockm, PocKrajRazl.krajkm, PocKrajRazl.RAZLIKA, PocKrajRazl.Poslprov, PocKrajRazl.Poslserv, PocKrajRazl.Zabeleska
FROM baraniotselect1 LEFT JOIN PocKrajRazl ON baraniotselect1.GBR = PocKrajRazl.GBRV;
Can anybody tell me please what am I doing wrong? Why the dataset remains empty?
I appreciate any help a lot
