Re: Application compile file using Embeded SQL in P

I don't think that's what Paul was asking... It might help if you post
a small example program. I think you're talking about something like:

int main(int argc, char **argv)
{
EXEC SQL BEGIN DECLARE SECTION;
const char *target = "db";
const char *user = "username";
EXEC SQL END DECLARE SECTION;

EXEC SQL CONNECT TO :target USER :user;
printf("sqlca.sqlcode: %ld\n", sqlca.sqlcode);

return( 0 );
}

which gives the following:

lkind(at)kelvin:~% ecpg test.pgc
lkind(at)kelvin:~% gcc -Wall -lecpg test.c
lkind(at)kelvin:~% ./a.out
sqlca.sqlcode: -402

So, if that's not what you have...
