Hi,

I have a set of libraries and C/C++ programs with embedded access to
a PG database. I'm using ecpg. I'm working on a Linux RedHat9 platform.

Until now I was in PG 7.4.2 :
[clipg@li SrcLib]$ ecpg --version
ecpg (PostgreSQL 7.4.2) 3.1.1
[clipg@li SrcLib]$ g++ --version
g++ (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
Copyright (C) 2002 Free Software Foundation, Inc.

and without any problem.

I installed PG 8.0.0beta2 :
[clipg@li SrcLib]$ ecpg --version
ecpg (PostgreSQL 8.0.0beta2) 3.2.0

And if I try to recompile I find pre-compiled errors, variables which
are defined in an include file are not "seen".
Is there any known problem or bug about this ?

Detail :
======= Precompiling DbTablesFk.pgc =======

ecpg DbTablesFk.pgc -I/VALE/users/clipg/Server/Include -o DbTablesFk.cc
DbTablesFk.pgc:144: ERROR: trying to access an undeclared cursor MAX_FK

DbTablesFk.pgc:144: ERROR: syntax error at or near "IN"


and in the program :
....
EXEC SQL INCLUDE DbTablesUtilPg.hh;
....

EXEC SQL PREPARE S FROM :sqlstmt;
EXEC SQL DECLARE C_FK_COL CURSOR FOR S;
EXEC SQL OPEN C_FK_COL;
EXEC SQL FETCH MAX_FK IN C_FK_COL INTO :fk_id_L , :valid_L, :target_t_L;

with MAX_FK a variable defined in the file
/VALE/users/clipg/Server/Include/DbTablesUtilPg.hh :
exec sql define MAX_FK 100;

If I replace the MAX_FK variable by its value it's OK.
If I define the MAX_FK variable directly in the program (and not
in an include file) it's OK.

Any idea ? Thanks for all, Valerie.

I think your problem is the semicolon.

I received this bug report and will take care of it as soon as I find
time. Since I am travelling next week to give PostgreSQL training, this
will take at least a week or so.

This works nicely for me with ecpg 3.2.0. It may be that ecpg
does not find the include file. But then it should also print that.

I had the file in "." where ecpg found it and the constant was correctly
translated.

I'm not even sure this is the reason. Could you please try moving the
file to "." to see if it works?

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match

But why ecpg found it in the 7.4 version ?
Following a remark I removed the semi-colon at the end of each
exec sql define xxxxxx
(I had : exec sql define xxxxxx ; )
in the include file. No result.

Someone from the pgsql-fr-generale list seems to have the same problem.

Thanks for your reply, Valerie.
