How to handle empty fields in database....

Hi,


I'm using Recordset to retrieve data records from the database and place

them in a ListView.


The problem I'm facing now is that some of the fields in the recordset is

empty. When I tried to run my application, it just stop at the record which

has an empty field and returns "Invalid use of Null'.


I would like to know what I should do for the recordset to retrieve empty

fields from the database.


Thanks in advance

Hi


This is covered in the Open FAQ in the CodeGuru/vb site - to fix your problem, simply append an empty string (ie. "") to the assignment,


e.g.


Text1.Text = oRecordSet.Fields("TestField") & ""


That way, any null value is converted to an empty string.


Look at then Open FAQ for more help

Hello Angus,


the other way as that of Chris is that you check in your program, if a field is empty, with the function isnull.


if not isnull(Recordset!Field) then ... else ...

You could probably check with the ISnull Function when you are retriveing from the databse , branch off when it is Null
