Hello,
I've found a solution, may be it isn't "chic" and may be it is a ECPG bug but it
work.
Follow this example:
-- This is the stored function
CREATE FUNCTION myfunc(refcursor) RETURNS refcursor AS'
DECLARE
ref ALIAS FOR $1;
BEGIN
OPEN ref FOR SELECT * FROM mytable;
RETURN ref;
END;
-- This is a piece of ECPG that call the stored function above
EXEC SQL SELECT myfunc('mycursor');
while (sqlca.sqlcode != 100)
{
EXEC SQL FETCH mycursor INTO ... ... ;
... ... ...
}
EXEC SQL CLOSE mycursor;
compiling the above piece of code the ECPG compiler will output:
filename.pgc:xx: ERROR: trying to acces an undeclared cursor mycursor
but it will produce a complete filename.c output anyway and compiling it with cc
or gcc you
will the SELECT output.
It isn't nice but work :)
If you have any other ideas please post it to me, thank you.
