Re: how to store a query, that results in a table

Hi, there,

If the client machine is a trusted machine in your company, use remote
shell 'rsh' can
call a script of SQL.
If not , you had better use embeded SQL.

I don't know how visual basic embed SQL, but I think is same way as other
language,
in postgres:
#db> create user robot with password 'wowwow';
$db> grant all on table1 to robot;

In perl , it's very similar like this:
use Pg;
my $conn;
sub connectDb {
$conn = Pg::connectdb("dbname=db host=dbserver port=5432
user=robot password=wowwow");
if ( $conn->status != Pg::PGRES_CONNECTION_OK ) {
die "Cant open postgres! : " . $conn->errorMessage . "\n";
}
return;
}
#main
connectDb();
my $query="select * from table1 where row1=parameter1";
print $query,"\n";
my $res=$conn->exec($query);
$res->cmdStatus || die $conn->errorMessage.":$!\n";
my $rows= $res->ntuples;
for (my $k = 0 ; $k < $rows; $k++){
my $field1=$res->getvalue($k,0);
my $field2=$res->getvalue($k,1);
print $field1,"\t",field2,"\n";
}
