Field list is blank

Greetings eveyone. I am using Access 2003 and SQL Server 2000. I am trying
to make a procedure the record source of a new form, but in design view the
field list is empty. The procedure has several variables, all of which may
be null, and the where clause is constructed dynamically. I have many other
forms with the *exact* same set up. I use an unbound form with text boxes to
pass the parameters to the procedure and open the main form. If I execute
the procedure manully, all the records are returned as expected. I tried
using the form wizard to make the form, but when I choose the procedure as
the record source, the field list is blank there also. Even without being
able to add fields to the form, when I open the form I can see the correct
record count at the bottom. I am completely flumoxed. I seem to remember
having this problem maybe a year ago, but I can not remember what I did to
fix it. Below is the procedure if it matters. Thank you.

Greg

What are you expecting? The metadata is not available because the select
query is dynamically created. Build the form, add the controls (text box,
combobox, etc.) and either their control source manually.
 
Thanks for the reply. What is the most important part of my post, is that I
have many other forms set up the *exact* same way. In fact, since there were
so many variables used to construct the where clause here, I copied another
procedure I had written, with the same number of variables, and simply
changed the variable and table and field names. If I open the form wizard,
and choose the procedure i copied, then all the fields show up in the field
list. If I choose this new procedure, however, no fields appear.

What version of Access are you using?

It's quite possible that once the SP has been executed at least one time,
Access remember the metadata that has been used this last time and reuse it.
However, if anything changes, then you will be using some metadata that
possibly won't be available the next time the procedure is run.

I've just made a test with one of my one SP based on a dynamically build
query string and with it, Access 2003 didn't remember the metadata from
execution to execution. Later, I will repeat the test with a simpler SP but
I don't see the point to it: if the fields list viewer is empty, then all
you have to do is to fill manually the control source.

Thank you again Sylvain. Ok, I created a new form with my sp as the record
source. Then I added a text box, and tried to manually type in the control
source. I tried both the field name only, and also three part name. I get
the error "no such field in the field list". Is there another way I need to
manually set the control source? I am using Access 2003.

Well, I got it to work. For some reason it did not like the @Order variable.
I took it out
and the fields appeared in the field list. There are only 20 or so records
in the table, so I guess
I can live without the order by.

Why can't you use Order instead of @Order?

I tried this

SELECT @SELECT = @SELECT + ' ORDER BY region,[name]'

in the line before EXECUTE, but as soon as I introduce the ORDER BY, either
by hard coding it or
by using a variable, the fields would not show up in the field list. My
understanding of what is going on
behind the scenes is not great enough to figure out why this would happen.
All I know is that when
I took out the ORDER BY, the fields appeared.
