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 float4[]);
in my C++-program a piece of code is:
main()
{
char *nr_string, *some_other_string;
PgDatabase test(pgenv, "test");
test.Exec("begin");
test.Exec("declare c cursor for select * from test");
for(int i=0; i<test.Tuples();i++)
{
nr_string = test.GetValue(i, "nr"); // obtaining the value in 'nr' is easy
some_other_string = test.GetValue(i, "some_value[1]"); // this gives an error
// PQgetvalue: ERROR! field number -1 is out of range
// so how do I obtain values in some_value[1], some_value[2] .... ?
}
}
any help would be appreciated.
bye
