Over the past few years, XML has emerged as the new standard for data transmission, and its use is becoming more prevalent as companies continue to adopt XML-based solutions.

Data Bind() this is wht i have wht i found is that i get the count a 0 though when i execute the query uisng sql i get the records but here i get the count to 0 anything missing hi, try this code (please convert into VB language) may be problem in ur query or Report class step 1:- create dataset and format the report step 2:- Bind crystal reportviewer /////Code behid using Crystal Decisions. so check your query again in sql i get the records rm tthe table everytime as u said i even tried with that sql frm which i get the records but still the same so i am sure the prblm is with xsd dataset is there anything else to configure in the xsd dataset or any other method how u creating dataset(xsd).

Another consideration when using Oracle XML DB is that the insertion time for a single XML file is generally limited by a single CPU's speed.In other words, having multiple processors does not help the throughput of a single document.For example, consider a situation in which a complex, single-rooted 700MB document needs to be inserted by use of schema-based storage.when i click on the button a new page is opened with crysatl report viewer my temp datable gets generated dynamically and gets populated with the few selected records as the table name is genearted dynamically i dont have the table name to refer it in the dataset first i tried ds. its in normalpath as files in my xsd file it has the same fields as in the query] SQLSTR = " SELECT * into rpttemp FROM temp1 WHERE code=1 order by name" Dim da As Sql Data Adapter = New Sql Data Adapter(SQLSTR, conn) da. Write Xml Schema("C:\folder\report.xsd") thr' code i wrote this line on report button click before callingg/ setting the crystal report viewer when i exeuted this code the was ceated then i build the solution and in the databse expert of crystal report i tried to make new connection nd refrenced this , but when i clicked it further it showed no items and hence selected table pane was blank and no fileds were avaliable so i manually created using add items and selecting dataset(dataset1) and in that i referenced my main table which had all the records frm field exploerer i set the fields that i need in crystal report using drag methood and tried setting the ds to crystal report but its displayed balnk this is my while code sql = " SELECT * into rpttemp FROM maintable WHERE fldcode=1 order by name" Dim da As Sql Data Adapter = New Sql Data Adapter(sql, conn.
