mysql - Using Excel column data to create sql statement that queries database

Question

I am looking for any advice on how i can read a single column in excel that contains 500 user_id's and query a database to display results in a WPF application. A user can own or rent so the SQL would look like;

SELECT * FROM users WHERE own= 'user_id' or rent= 'user_id'

This is fine for one user but i want to read each user_id and concatenate it to the SQL statement to pull out all results from the database. Any one have any easy way of doing this?

Replace the range as necessary, credit to brettdj on the join - Simple VBA array join not working

Sub test()

    Dim strQuery As String
    Dim strVals As String

    Dim rngTarget As Range
    Set rntTarget = Range("A1:A7")

    Dim varArr
    Dim lngRow As Long
    Dim myArray()
    varArr = rntTarget.Value2

    ReDim myArray(1 To UBound(varArr, 1))

    For lngRow = 1 To UBound(varArr, 1)
        myArray(lngRow) = varArr(lngRow, 1)
    Next

    strVals = "('" & Join$(myArray, "','") & "') "

    strQuery = "SELECT * FROM users WHERE own in " _
        & strVals & "or rent in " & strVals


End Sub
