B4J Question jSQL 1.51 NullPointerException Issue

[Mashiane]

Kinda confused...

Public Sub ExecuteMap(jSQL As SQL, Query As String, StringArgs() As String) As Map
    Dim res As Map
    Dim cur As ResultSet
    If StringArgs <> Null Then
        cur = jSQL.ExecQuery2(Query, StringArgs)
    Else
        cur = jSQL.ExecQuery(Query)
    End If
    If cur.NextRow = False Then
        'Log("No records found.")
        Return res
    End If
    res.Initialize
    For i = 0 To cur.ColumnCount - 1
        Dim fName As String = cur.GetColumnName(i)
        Dim fValue As String = cur.GetString2(i)
        Log(GetType(fValue))
        Log(fName)
        Log(fValue)
        'If fValue = "null" Then fValue = ""
        res.Put(cur.GetColumnName(i).ToLowerCase, fValue)
    Next
    cur.Close
    Return res
End Sub

A funny thing here, some records in my database table return the field names properly and the column values and some just return NullPointerException at the Log(GetType(fValue)) line. If I comment out the

If fValue = "null" then fValue = ""

, it also just crashes on that line. An intergrity check

PRAGMA integrity_check

returns ok. What could I be doing wrong?

I want the map that is returned not to have null values as those need to be just blank.

[Erel]

You should check whether it is null before you try to log its type.

If fvalue = Null Then Continue

@Erel, perfect! thanks
