Using a for next loop to assemble a search string from split array
Posted on 2011-03-04
Hi all -- I'm new (back) to EE and need some help. I have a textbox on a form (TxtAttribute1) and I want to pull the string out of it and then do a split based on ;. That part seems to be fine. However, I have a search string (strWhere) to which I want to add each member of the array, along with the appropriate filtering language for each individual member. There are other boxes that add similar filtering language to strWhere (date ranges, attributes, etc) but which aren't lited here. The code below doesn't cause any errors but it only returns the first member of the array (nothing else). I've tried everything I can think of with the loop and am at wit's end. so this is max points. I'm sure it's something small, so help me out, y'all....!
Dim strWhere As String
strWhere = "1=1"
Dim i As Integer
Dim sparts() As String
If Nz(Me.TxtAttribute1) <> "" Then
sparts = Split(Me.TxtAttribute1, ";")
For i = LBound(sparts) To UBound(sparts)
strWhere = strWhere & " AND " & "BaseDataTableItemA.TxtAtt
Exit For
Next i
End If
Dim strWhere As String
strWhere = "1=1"
Dim i As Integer
Dim sparts() As String
If Nz(Me.TxtAttribute1) <> "" Then
sparts = Split(Me.TxtAttribute1, ";")
For i = LBound(sparts) To UBound(sparts)
strWhere = strWhere & " AND " & "BaseDataTableItemA.TxtAtt
Exit For
Next i
End If

try this
Dim strWhere As String
strWhere = "1=1"
Dim i As Integer
Dim sparts() As String
dim strLst as string
If Nz(Me.TxtAttribute1) <> "" Then
sparts = Split(Me.TxtAttribute1, ";")
For i = LBound(sparts) To UBound(sparts)
strLst=strLst & "," & chr(39) & sparts(i) & chr(39)
Next i
strLst=mid(strLst,2)
strWhere = strWhere & " AND " & "BaseDataTableItemA.TxtAtt
End If
Dim strWhere As String
strWhere = "1=1"
Dim i As Integer
Dim sparts() As String
dim strLst as string
If Nz(Me.TxtAttribute1) <> "" Then
sparts = Split(Me.TxtAttribute1, ";")
For i = LBound(sparts) To UBound(sparts)
strLst=strLst & "," & chr(39) & sparts(i) & chr(39)
Next i
strLst=mid(strLst,2)
strWhere = strWhere & " AND " & "BaseDataTableItemA.TxtAtt
End If
It pulled the correct values from the array (huge) but unfortunately I need it formatted like the string in the attached image. I think we're really close -- !

<It pulled the correct values from the array (huge) but unfortunately I need it formatted like the string in the attached image> Why?
what are the values in
BaseDataTableItemA.TxtAttr
and the values from Me.TxtAttribute1?

and the values from Me.TxtAttribute1?
strWhere is used to filter records in a subform that only displays after the search button is clicked. The subform's recordsource is BaseDataTableItemA, so whatever string criteria you enter in Me.TxtAttribute1 go to filter the records in the same named column in BaseDataTableItemA. I tried the code you provided and while it did get the array right, the filter didn't know what to do with the ( ) or lack of a second string.
OK - here it is.

bcbuchanan,
do you know that the table that you have is not normalized?
what is the purpose of this table?
when you have repeating field, like what you have in your table, you need to break them out into separate tables..
have a read on this link
Description of the database normalization basics
http://support.microsoft.com/?kbid=283878
see also this demo about creating a third table to break a many to many relationship between two tables
http://office.microsoft.com/en-us/access-help/demo-set-the-relationship-between-two-tables-HA010254901.aspx?pid=CH100739911033
there are also lots of information on that link regarding table normalization

I was able to go back into your first comment and reformat the filtering so it looks like this. Still needs to be optimized but it works.
If Nz(Me.TxtAttribute1) <> "" Then
sparts = Split(Me.TxtAttribute1, ";")
For i = LBound(sparts) To UBound(sparts)
strLst = strLst & " AND " & "BaseDataTableItemA.TxtAtt
Next i
strLst = Mid(strLst, 2)
strWhere = strWhere & strLst
End If
BTW, pls don't assume that the DB isn't normalized -- this was just a test DB to figure out this filtering string issue with multiple fields on one form to search through one table's records. The actual DB I'll be using this with has four or five base tables and about 3 MTM tables. But, you gave me the direction above to solve the rest of the problem on my own, so I'll be happy to give you the points.
