由于字段中的逗号导致MS Access 2010 SQL查询语法错误

Question

I've been having issues with this code I've written to update a field (txtUOM) in MS Access 2010.

Private Sub cboSelector_Change()

  Dim myItemCode As String
  Dim QfindUOM As String

  myItemCode = Me.cboSelector.Column(0)
  QfindUOM = ("SELECT item_details.uom from item_details 
              where item_details.itemCode=" & myItemCode & " end")

  DoCmd.RunSQL (QfindUOM)

End Sub

At this point, I haven't gotten around to actually updating txtUOM since the SQL won't even run. The syntax error hits me,because myItemCode has commas inside (ie 822,60 or 6,01) and I can't get rid of this because the database I've been asked to work with has this as the 'item numbers' of the inventory. Any suggestions on how I might be able to manage this? I've tried adding parenthesis and apostrophes but they don't seem to help. For example, in the case of item 6,09:

Run-time error '3075': 
Syntax error (comma) in query expression 'item_details.itemCode=6,09 end'.

There are also some items with itemCodes that don't have commas inside (ie 6909), and the error I get is as follows:

Run-time error '3075':
Syntax error (missing operator) in query expression 'item_details.itemCode=6909 end'.

I'm guessing there's something going terribly wrong in my code and would really appreciate any suggestions you can give!

Thanks for taking the time to read this question!

Answer 1

Add single quotes:

 QfindUOM = ("SELECT item_details.uom from item_details 
          where item_details.itemCode='" & myItemCode & "' end")

or Double, I forget with access:

 QfindUOM = ("SELECT item_details.uom from item_details 
          where item_details.itemCode=""" & myItemCode & """ end")
