Question

I am having some issues with a parameterized SQL Lite query. I can’t seem to get the SQL Lite Parameter to accept the String value

Using cmd As SQLiteCommand = pConn.CreateCommand()
    If tblLang = "en" Then
        cmd.CommandText = "UPDATE [AT_Strings] SET [Data] = @tblData + 1 WHERE [RecordID] = @ID AND [language] = @tblLang1"
        Dim tblData As New SQLiteParameter("@tblData")
        Dim ID As New SQLiteParameter("@ID")
        Dim tblLang1 As New SQLiteParameter("@tblLang1")
        cmd.Parameters.Add(dataText)
        cmd.Parameters.Add(ID)
        cmd.Parameters.Add(tblLang)
    Else
         cmd.CommandText = "UPDATE [AT_Strings] SET [Data] = @dataText + 1 WHERE [RecordID] = @ID AND [language] = @tblLang1"
         Dim tblData As New SQLiteParameter("@dataText")
         Dim ID As New SQLiteParameter("@ID")
         Dim tblLang1 As New SQLiteParameter("@tblLang1")
         cmd.Parameters.Add(dataText)
         cmd.Parameters.Add(ID)
         cmd.Parameters.Add(tblLang)
    End If

    cmd.ExecuteNonQuery()
 End Using

The error is as follows….

Unable to cast object of type 'System.String' to type 'System.Data.SQLite.SQLiteParameter'.

This is how I solved this issue…

Dim SqlString As String 
SqlString = "UPDATE [AT_Strings] SET [Data] = @Data WHERE [ID] = @ID AND [Language] = @Language"  

Using cmd As New SQLiteCommand(SqlString, pConn)    
    cmd.CommandType = CommandType.Text     
    cmd.Parameters.AddWithValue("Data", dataText)    
    cmd.Parameters.AddWithValue("ID", f4)    
    cmd.Parameters.AddWithValue("Language", tblLang)     

    pConn.Open()    
    cmd.ExecuteNonQuery()    
    pConn.Close() 
End Using 

Hope this helps someone else!!
