Обсуждение: PG 8.2.7, ECPG & Composite types..

Hey folks,

Running PG 8.2.7 and we have decided to use composite types.  However,
we are coming up against an issue with ECPG when trying to insert data
into tables using composite types.  It's almost like ECPG doesn't allow
composite types.  We are novices in this regard so please be gentle. :-)

Here's something really basic that we can get working in psql but not in
ECPG:
       create type C_AMT as (           amt         float8,           iso         integer           );
       create table items (           itemNum     serial8 primary key,           name        varchar(127),
price      C_AMT,           stock       integer           );
 

and in ECPG we have tried various things which either end up with a
mismatch between column count & value count; or generate an error
where the values for the embedded composite type have been melded
together as a text string and telling us that the resulting string
is an invalid floating point value.  Following is an example of the
latter error:
   exec sql insert into items ( name, price.amt, price.iso, stock )               values ( 'Test Item', 99.2, 1, 101
);

Similarly,   exec sql insert into items ( name, price, stock )               values ( 'Test Item', ( 99.2, 1 ), 101 );

Are we chasing a dream or just misguided?

Any help would be greatly appreciated.

Fred.

It says this has an invalid floating point?

Could you produce a small test case so we can work on the same example?
Also could you enable logging and post the logs?
