Do While Skip in Selecting...

Hello:

I have one table and it contains a column named ID Number, and a column named Date. I have a Do While statement that runs a SQL select statement a few times based on the number of records with the same ID Number. During the Do While statement the information is copied into another table and deleted from the old table. After I look at the results, I see that at the second Do While loop, the data was not selected and the Select statement did not run... so the old variable value from varValue is used again... Any reasons on why?

Here is a code snippet of what is going on:

 Do While varCount < varRecordCount
 conSqlConnect.Open()
 cmdSelect = New SqlCommand ("Select * From temp_records_1 where [id number]=@.idnumber and date<@.date", conSqlConnect)
 cmdSelect.Parameters.Add( "@.accountnumber", "10000" )
 cmdSelect.Parameters.Add( "@.date", dtnow )
 dtrdatareader = cmdSelect.ExecuteReader()
 While dtrdatareader.Read()
 If IsDbNull(dtrdatareader("value")) = false Then
 varValue = dtrdatareader("value")
 End If
 End While
 dtrdatareader.Close()
 conSqlConnect.Close()
'#####The information above is copied to another table here
'#####The record where the information was received is deleted.
 varCount = varCount + 1
 Loop

Any ideas?After playing around with this for a while, I found that the select statement is incorrect. The part where it says date<@.date... this selects more than one row, instead of just selecting one row.

I read articles that discuss using select MAX(column) but that will only return one column... how can I select a row based on a column with the maximum value?|||ok... great got it working now... just post the answer here for future reference... I went ahead and did Select Top 1 * instead of Select *... it solved everything...
