Specify data types in Access parameter queries

Are your Microsoft Access users having a difficult time getting a parameter query to work? The problem may be due to a mismatched data type. Learn how to change the data type for the query parameter.

When Microsoft Access users complain that a parameter query does not work, it may be that the Query Parameter's data type does not match the field's data type.

For example, to obtain a listing of the hours each employee worked for the week ending 05/20/2005, the user might enter 5/20/05. Since, by default, the data type for a query parameter is text, it would not match a Week Ending field whose data type is Date/Time and formatted as mm/dd/yyyy.

If you don't want your users to concern themselves with date formats, change the data type for the query parameter by following these steps:

  1. Open the Parameter Query in design view.
  2. Right-click the table pane.
  3. Select Parameters.
  4. Under Parameter, type Enter Week Ending Date (your parameter prompt without the brackets).
  5. Select Date/Time from the Data Type drop-down box.
  6. Click OK.

Now users can enter the week ending date in any format and still obtain the correct results.
