I tried the following (screwed up spacing due to pine autowrap :-)
exec sql
insert into
customer(uid,id,name_first,name_middle,name_last,company,
address1,address2,city,state,country,zip,phone_work,
phone_home,phone_fax,email,date_entered,billing_terms,
confirmation_method)
values (:uid,:uid:id_n,:name_first:name_first_n,
:name_middle:name_middle_n, :name_last:name_last_n,
:company:company_n,:address1:address1_n,
:address2:address2_n,:city:city_n,:state:state_n,
:country:country_n,:zip:zip_n,:phone_work:phone_work_n,
:phone_home:phone_home_n,:phone_fax:phone_fax_n,:email:email_n,
date('now'),:billing_terms:billing_terms_n,
:confirmation_method:confirmation_method_n);
Adding the indicators to the above statement causes ecpg(from the 6.4.2
distro) to seg fault while processing the statement. I defined each
indicator as the original var name with _n added to the end. I tried
type int and long. The statement preprocesses fine without the indicator
vars.
I dont know the proper method for looking into core files but by trial and
error I got gdb to produce (is this correct way to do this?)

Does anyone have a working example of using indicator vars with ecpg?
Thanks.

Strange. Please try the attached test file. I defined all your variables as
int and it works with ecpg versions 2.4.4 (PG 6.4.1), 2.4.9 and 2.5.0.

Yes.

Could you please check where in ECPGdump_a_type it dumps core? The function
is a pretty short one.

Yes the test files worked. Until I added the other variables used in the
insert statement. I put the following in the sql declare section (too
lazy to type them all).
char *uid,*id,*name_first,*name_middle,*name_last;
And then ecpg bombs with the seg fault.

Sure, if I can figure out how. Can I do that via gdb? Or do I just need
to use puts throughout the function?
I'd also be willing to try the cvs versions if someone could tell me where
to get them, I cant find cvs download instructions on the postgresql site.
