using a variable to Set rst - ms-access

Question

I'm trying to open a record set using a SQL string. I get run time error 3061 "Too Few Parameters." any help would be appreciated.
Dim stAppName As String
Dim stURL As String
Dim rst As Recordset
Dim dbs As Database
Dim stringToSearch As Integer
Dim strSQL As String
Set dbs = CurrentDb
stringToSearch = InputBox("What is your route #?", "Enter route #: ")
strSQL = "SELECT ESRP.* FROM ESRP WHERE ESRP.Route=stringToSearch"
Set rst = dbs.OpenRecordset(strSQL)

Answer 1

Please change the code line of strSQL as follows, as suggested by Fionnuala you need to use variable outside the quotes.
Assuming Route field is Text data type, we need to put single quote for strings, if its number no single quote, for dates put # instead of single quote
strSQL = "SELECT ESRP.* FROM ESRP WHERE ESRP.Route='" & stringToSearch & "'"

Answer 2

It's a little sample, maybe it can help you
Public Function fn_SQL_dbOpenRecordset(Optional vsql As String = "") As Recordset
Dim dbs As DAO.Database
Dim rs As Recordset
On Error GoTo END_CODE
'Set the database
Set dbs = CurrentDb
Set rs = dbs.OpenRecordset(vsql, dbOpenForwardOnly) 'you can use: dbOpenDynamic; dbOpenSnapshot; dbOpenTable
Set fn_SQL_dbOpenRecordset = rs
Exit Function
END_CODE:
Set fn_SQL_dbOpenRecordset = Nothing
End Function
Public Sub Program_Test()
On Error GoTo ERROR_SUB
Dim rs As Recordset
Dim sName As String
sName = "Joe"
sName = "'" & sName & "'" 'WARNING: BE CAREFUL WITH SQL INJECTION !!! Google it
Set rs = fn_SQL_dbOpenRecordset("select * from table1 d where PersonName = " & sName)
Dim i As Long
i = 0
While Not rs.EOF
Debug.Print rs(0).Value & " - " & rs(1).Value
rs.MoveNext
Wend
ERROR_SUB:
On Error Resume Next
If Not rs Is Nothing Then rs.Close
Set rs = Nothing
End Sub
