pro_vb thread: Inserting a Null Value


Message #1 by =?iso-8859-1?B?Ld7keuvxa/as?= <news@l...> on Fri, 15 Nov 2002 10:22:44 +0800
I think you can change to this:
If (Trim(lblLabel(38).Caption) =3D "" Then
	strSQL =3D "Update ra set raCode =3D NULL"
else
...
end if
cn.execute strSQL

Because the sql statement will be evaluated by the rdbms.

does anyone know why this can't insert a null value to a particular 
field
i'm using vb6 and mySQL

strSQL =3D "Update ra " & _
"set raCode =3D '" & IIf(Trim(lblLabel(38).Caption) =3D "", Null,
lblLabel(38).Caption) & "' "
cn.execute strSQL

everytime i execute this statement the raCode fields always contain a 0
