Hye all..I am facing a problem to pass the result from query to a label.
When I try with a gridview like code below, it works (displaying 'SEP3FM' in the gridview). However when I replace the code to ;
Dim loc1 As String = OracleDbLib.OracleDbBase.ExcuteScalar(sqlDATE)
Me.lblLoc.Text = loc1
it shows no error but nothing appear. When I debug, the 'loc1' value contains "Nothing". The result is in varchar datatype.How to display the value in label? Thanks for your help guys. :)

Dim sqlDATE As String = " Select DVLPER.MANUFACTURERESULTS.WORKWARD" & _
                                " From (Select Max(DVLPER.MANUFACTURERESULTS.RESULTINPUTNO) As MAX1" & _
                                " From(DVLPER.MANUFACTURERESULTS)" & _
                                " Where DVLPER.MANUFACTURERESULTS.JOBNO = '404001039232') DB1 Inner Join" & _
                                " DVLPER.MANUFACTURERESULTS On DB1.MAX1 =" & _
                                " DVLPER.MANUFACTURERESULTS.RESULTINPUTNO"

Dim loc1 As DataTable = OracleDbLib.OracleDbBase.BuildDataTable(sqlDATE)
GridView2.DataSource = loc1
GridView2.DataBind()

Solution 1

Whats the return type of OracleDbLib.OracleDbBase.ExcuteScalar(sqlDATE) I think you need to cast it to string.

Can you add a watch while debugging and see what is stored in this(loc1)?

Will this work with following code?
Dim loc1 As String = OracleDbLib.OracleDbBase.ExcuteScalar(sqlDATE)

Nilesh Patil Kolhapur 23-May-12 6:40am

yes add .toString() at end

By using Rows[0][0], do u mean that I need to pass the value from gridview into the label? I am inteding to remove the gridview and straightly display the value into the label.
