Arranging inquiries
Access enables you to apply various sorts without a moment's delay while you're planning your question. This enables you to see your information precisely the way you need.
A sort that incorporates in excess of one arranged field is known as a multilevel sort. A multilevel sort enables you to apply an underlying sort, at that point additionally arrange information with extra sorts. For example, on the off chance that you had a table loaded with clients and their locations, you may decide to first sort the records by city, at that point one after another in order by last name.
At the point when in excess of one sort is incorporated into an inquiry, Access peruses the sorts from left to right. This implies the furthest left sort will be connected first. In the case underneath, clients will be arranged first by the City where they live and after that by the Zip Code inside that city.
To apply a multilevel sort:
- Open the inquiry and change to Design see.
- Find the field you need to sort first. In the Sort: push, tap the drop-down bolt to choose either an Ascending or Descending sort.
- Rehash the procedure in alternate fields to include extra sorts.

Concealing fields inside inquiries
Once in a while you may have fields that contain imperative criteria, yet you should not have to really observe the data from that field in the last outcomes. For instance, take one of the questions we worked in our last lesson: an inquiry to discover the names and contact data of clients who had put orders. We included Order ID numbers in our inquiry since we needed to ensure we just pulled clients who had put orders.
Notwithstanding, we truly didn't have to see this data in our last inquiry comes about. Truth be told, in the event that we were simply searching for client names and addresses, seeing the request number blended in there might have been diverting. Luckily, Access makes it simple to shroud fields while as yet including any criteria they contain.
To conceal a field inside a question:
- Open the question and change to Design see.
- Find the field you need to cover up.
- Tap the checkbox in the Show: column to uncheck it.
- To see the refreshed question, select the Run charge. The field will be covered up.
To unhide a concealed field, essentially come back to Design view and tap the checkbox in the field's Show: push once more.
