Search Form Using Three Criteria

L

Londa Sue

Hello,

I'd like to develop a search form that will allow users to search using
three criteria. The criteria are via combo boxes:

CSISystem
DocumentType
Status

I have a command button named "Retrieve Records" which should find all
records in tbl_record or qyr_record that match the selected criteria. These
values will populate a list box named "SrchList" so that users can
double-click on the desired record. What I've tried has not worked, so any
help is appreciated.

Thank you,

Ken,

You're marvelous. I'm almost there.

The application has a search form (frm_search) that is built on a secondary
query of qry_record2. On this page in the header, there are three combo
boxes from which users will be able to select for searching. They are (1)
CSISystem; (2) DocumentType, and (3) Status. The values that will be
filtered are in a list box (SrchList). Everything is working except the
filter on the list box, and I'm sure that's because I'm not a programmer so
all the language isn't clear to me right off. In any case, I'm having some
trouble with the following. What am I supposed to put in this section?

Private Sub cmdSearch_Click()
Dim strSQL As String

On Error Resume Next

DoCmd.Hourglass True

' move focus to clear button
Me.cmdClear.SetFocus
' build sql string for form's RecordSource
strSQL = BuildWhereString
strSQL = "SELECT * FROM " & strMainformRecordSource & _
IIf(strSQL = "", "", " WHERE ") & strSQL & ";"

Me.RecordSource = ""
Me.RecordSource = strSQL

Call SetVisibility(True)

DoCmd.Hourglass False


End Sub

Here's what I put in this section that is not working:

Private Sub cmd_search_Click()
Dim strSQL As String

On Error Resume Next

DoCmd.Hourglass True

' move focus to clear button
Me.cmd_clear.SetFocus
' build sql string for form's RecordSource
strSQL = BuildWhereString
strSQL = "SELECT * FROM " & SrchList & _
IIf(strSQL = "", "", " WHERE ") & strSQL & ";"

Me.SrchList = ""
Me.SrchList = strSQL

Call SetVisibility(True)

DoCmd.Hourglass False


End Sub

Okay. That does the job. This help on this site is a wonder.

I've another issue now. When other data related to record is added (such as
"Author"), that data is showing up in the list box, although the list box is
based on qry_record2 which is only ID, DocumentID, DocumentTitle,
DocumentType, ReleaseDate, Revision, System, and Status. Should I do a
SELECT FROM to keep this list to just those I want? I've never had this
happen with list boxes. I'll check the rest of the code and make sure I
haven't mixed my queries. (I think for efficiency I should have put the
search features on the main form but that has filter buttons of another sort
and there are plenty of those.)

Thank you so very much,

Londa Sue

It'll be easier for us to troubleshoot if you can show actual example of
what you mean by "showing up". Also, not knowing the SQL statement of
qry_record2, and not knowing the other properties of the listbox, it's hard
to give any suggestions yet.

I changed the source to qry_record since it was the same data. I currently
only want to display seven fields (the primary key is hidden--set at width
0"). When the Search button is clicked, the records are filtered
appropriately, but I get some extra fields that I do not want to display
(such as author, owner). The other fields are shifted two to the right.
Here is the code for the form:

Option Compare Database
Option Explicit


Private Const strContainWildCard As String = "*'"
Private Const strEqual_1 As String = "= '"
Private Const strEqual_2 As String = "'"
Private Const strMainformRecordSource As String = "qry_record"
Private Const strNoStartWildCard As String = "Like '"
Private Const strStartWildCard As String = "Like '*"

Private Function BuildWhereString() As String
Dim strWhere As String
Dim varItemSel As Variant

On Error Resume Next

strWhere = ""

' ... build "CSI System" criterion expression
If Len(Me.CSISystem.Value & "") > 0 Then _
strWhere = strWhere & "CSISystem='" & Me.CSISystem.Value & "' And "

' ... build "Document Type" criterion expression
If Len(Me.DocumentType.Value & "") > 0 Then _
strWhere = strWhere & "DocumentType='" & Me.DocumentType.Value & "' And "

' ... build "Status" criterion expression
If Len(Me.Status.Value & "") > 0 Then _
strWhere = strWhere & "Status='" & Me.Status.Value & "' And "

' Strip off the trailing " And " text string
If Len(strWhere) > 0 Then strWhere = Left(strWhere, Len(strWhere) - _
Len(" And "))


BuildWhereString = strWhere
Exit Function
End Function

Private Sub SrchList_AfterUpdate()
' Find the record that matches the control.
Dim rs As Object

Set rs = Me.Recordset.Clone
rs.FindFirst "[ID] = " & Str(Nz(Me![SrchList], 0))

End Sub

I apologize that I didn't reply sooner.. somehow, I missed your reply in the
thread.

Are you saying that you see extra fields in the form's data set? Or in a
listbox's data set?
