Use parameter in the query


Is it possible to use following query with parameter for the number.

SELECT TOP 5 Table1.[Section No], Table1.[Field Value]
FROM Table1;

Can I use instead of 5 expression [Enter Parameter Value].

I need query which runs top records to be dynamic

You might dynamically change the query SQL in vba with an InputBox.

However, you could use a form to select how many records you want the query to return, then modify the query, or build the query on the fly in the Click event of a button on your form.  That is normally the way I do this when I want to select a variable number of records at a time.

Thanks a lot, fyed

If I need to input percentage value (instead of number) into text box do I need to change vba code?

Or I should not use percentage value with the form?
Dale FyeCommented:
Yes, if you want to use a percentage rather then an actual # of records, you should use something like

strSQL = "SELECT TOP " & me.txt_Percent & "PERCENT Table1.* FROM Table1"

If you want to configure it so that the user can select "Percent or Number", you could add a combo box following the text box with value list and Rowsource values of 'Percent' and 'Number'

Then the SQL might look something like:

     strSQL = "SELECT TOP " & me.txt_Number _
                 & IIF(me.cboPctOrNum = "Percent", " PERCENT ", " ") _
                 & "Table1.* FROM Table1"
