Hi all

I have the following problem:

I'm using libpq++ to acces a = Postgres-Database.

The table was created in psql using:

create table test values (nr int4, some_value=20 float4[]);

in my C++-program a piece of code=20 is:

main()

{

char *nr_string,=20 *some_other_string;

PgDatabase test(pgenv,=20 "test");

=20 test.Exec("begin");

test.Exec("declare c = cursor for=20 select * from test");

for(int i=3D0;=20 i<test.Tuples();i++)

{

nr_string = =3D=20 test.GetValue(i, "nr"); // obtaining the value in 'nr' = is=20 easy

= some_other_string =3D=20 test.GetValue(i, "some_value[1]"); // this gives an = error

//=20 PQgetvalue: ERROR! field number -1 is out of range

// so how = do I obtain=20 values in some_value[1], some_value[2] .... ?

}

any help would be = appreciated.

bye
