ACC2000: Query Returns no Records with an Indexed Field That Contains Dashes

When you run a query against data that contains dashes, and you are using the LIKE operator as criteria in the query, no rows are returned.

The field that contains the dashes is indexed. The LIKE operator does not work for this field in this case.

Steps to Reproduce the Behavior

1. Create a new Access 2000 database.
2. Create a table named Table1 that has a single Text field named Field1.
3. Add an index to the Field1 field.
4. Switch the Table1 table to Datasheet view.
5. Add the following data to the Field1 field:

      g2-1-40
      g2-1-41
      g2-1-42
      g2-1-43
      g2-1-44
   					

6. Close and save the table.
7. On the Insert menu, click Query. Click OK in the New Query dialog box to open the Query Designer. Close the Show Tables dialog box without adding any tables.
8. In the Query Designer, click SQL View on the View menu.
9. Type the following into the SQL view:

      SELECT Table1.field1
      FROM Table1
      WHERE (((Table1.field1) Like "g2-1*"));
   					

10. Run the query. Note that no rows are returned.
11. Close and save the query as Query1.
12. Open the Table1 table in Design view, and then remove the index from the Field1 field.
13. Close and save the table.
14. Run the Query1 query again. Note that now the correct rows are returned.
