VBA SQL query result error - sql

Question

There's no result or blank excel sheet in result of following SQL query. It works fine if I remove where condition but Its required. So kindly help me to correct my code with where condition. Code is follow-
Private Sub cmdOpenQuery_Click()
Dim strTableName As String
Dim strFieldName As String
Dim strFieldValue As String
Dim strFV As String
Dim strFieldType As String
Dim strBaseSQL As String
Dim strCriteria As String
Dim varItem As Variant
Dim strSQL As String
Dim qdf As DAO.QueryDef
Dim OutPut As String
Dim intCounter As Integer
Dim xlApp As Object
For Each qdf In CurrentDb.QueryDefs
If qdf.Name = "MyQry" Then
DoCmd.DeleteObject acQuery, "MyQry"
Exit For
End If
Next
strTableName = Me.[cboSelectTblQry]
strFieldName = Me.[cboWhere]
strFV = Me.[cboEqualto]
strFieldType = CurrentDb.TableDefs(Me.cboSelectTblQry).Fields(Me.cboWhere).Type
If strFieldType = 4 Then
strFieldValue = "[" & strFV & "]"
ElseIf strFieldType = 10 Then
strFieldValue = "['" & strFV & "']"
ElseIf strFieldType = 8 Then
strFieldValue = "[#" & strFV & "#]"
End If
strBaseSQL = "SELECT "
For intCounter = 0 To lstSelectTo.ListCount
lstSelectTo.Selected(intCounter) = True
Next intCounter
For Each varItem In Me![lstSelectTo].ItemsSelected
strCriteria = strCriteria & "[" & Me![lstSelectTo].ItemData(varItem) & "],"
Next
strSQL = strBaseSQL & Left$(strCriteria, Len(strCriteria) - 1) & " FROM [" & strTableName & "]" & " Where [" & strFieldName & "] = strFieldValue "
Set qdf = CurrentDb.CreateQueryDef("MyQry", strSQL)
If cboFormat = "Excel" Then
OutPut = "D:/Export_" & strTableName & "_" & Date & ".xlsx"
DoCmd.TransferSpreadsheet acExport, , "MyQry", OutPut
MsgBox " File has been exported to " & OutPut
DoCmd.Close
DoCmd.OpenForm "frmCreateQry"
Set xlApp = CreateObject("Excel.Application")
xlApp.Workbooks.Open (OutPut)
xlApp.Visible = True
ElseIf cboFormat = "PDF" Then
OutPut = "D:/Export_" & strTableName & "_" & Date & ".pdf"
DoCmd.OutputTo acOutputQuery, "MyQry", acFormatPDF, OutPut, True
MsgBox " File has been exported to " & OutPut
ElseIf cboFormat = "Word" Then
End If
ExitSub:
Exit Sub
ErrorHandler:
Resume ExitSub
End Sub

Answer 1

Your where condition is using strFieldValue as the value to look for. You should instead use the use held by strFieldValue for comparison. You're doing that properly with strTableName already. It is the same idea here. You'd need to enclose the value of strFieldValue in quotes when you add it.
strSQL = strBaseSQL & Left$(strCriteria, Len(strCriteria) - 1) & " FROM [" & strTableName & "]" & " Where [" & strFieldName & "] = '" & strFieldValue & "'"

Answer 2

I made some corrections and it's working now fine for all format like numeric, text and date type.
Following corrections made in Type condition :-
If strFieldType = 4 Then
strFieldValue = Me.cboEqualto
ElseIf strFieldType = 10 Then
strFieldValue = "'" & strFV & "'"
ElseIf strFieldType = 8 Then
strFieldValue = "#" & strFV & "#"
End If
and following correction in strSQL:-
strSQL = strBaseSQL & Left$(strCriteria, Len(strCriteria) - 1) & " FROM [" & strTableName & "]" & " Where [" & strFieldName & "] = " & strFieldValue & ""
