macro to remove field and restore original qry

As I mentioned in your previous question - I don't think this is the best/most efficient way of doing this.

What are you ultimately using these queries for?
Why not just select the fields you need from your table when and where you need them rather than building on and reverting your query to its original state?

Hi mbizup

using the qry to populate figures.....year end...

i understand what u are saying but the end users have no working knowledge of access. ..very limited. ..so hence the vba route they are happy to click buttons. .

so would strsql = DELETE * FROM qry xxxx WHERE Region
do????

The reason I'm suggesting the form approach is that it is more standard, generally considered 'best practice' to show the data through a form interface rather than directly displaying tables or queries (it gives you more control).  

That way, your users can see the data they want at the click of a button, and you as the developer are working with a single form and a single query, which have plenty of possibilities for *easily* displaying the data in a wide variety of ways.

Your criteria can also be easily handled like this.

Assuming you have a textbox on your form for CORE, set the SQL of your query to include all fields, but NOT the where clause:

SELECT Field1, Field2, Region FROM YourTable

Then this will display all fields with the core criteria:

Private sub cmdShowAll_Click()
       Docmd.OpenForm "YourFormName", WhereCondition := "Core = '" & me.txtCore & "'"
End Sub

Select allOpen in new window

Then this will display without the region and without the core criteria

Private sub cmdShowAll_Click()
       Docmd.OpenForm "YourFormName"
       Forms!YourFormName.txtRegion.Visible = False
End Sub

Select allOpen in new window
