Обсуждение: Problem with exec sql include

Hello.

I have a 2 files:  test.h and test.pgc.

In test.h, I defined:

typedef struct {
        long curid;
        char curnombre[20];
        char curfecha[10];
} struct_cursor;

And, in test.pgc, I want to declare:

    EXEC SQL BEGIN DECLARE SECTION;
        struct_cursor t_cursor;
    EXEC SQL END DECLARE SECTION;

But, when I do:  ecpg -I/<include_file_path> test.pgc,
I get:  test.pgc:7: ERROR: invalid datatype 'struct_cursor'

I know that I can include the typedef at DECLARE SECTION, but I don't
want to use that (test.h and test.pgc are only examples of the problem
bigest).

How can I resolve this?

Thanks.

ECPG does not parse anything outside EXEC SQL blocks, so how else should
it lear about your struct definition? You can of course use a EXEC SQL
TYPE command to define it for ECPG as well.

Thanks for you suggestion.

In the test.pgc file, I do:

   EXEC SQL BEGIN DECLARE SECTION;
        exec sql include test;
        struct_cursor t_cursor;
   EXEC SQL END DECLARE SECTION;

... and it works fine.  It is correct????

Thank you again.

Depends on what test.h contains. ecpg has to learn the definition of
your struct somewhere.
