Yup, that is what I would like to get rid of. ns_pg_exec is not
something I would like to use. I'd like to think we are above the
PHP-esque pg_connect/my_connect/pg_exec/etc!
Considering how easy tcl makes such things, I'm rather surprised
oacs doesn't do something like
rename ns_db _ns_db
proc ns_db {args} {
if {[is_postgres]} {
eval ns_pg_exec $args
} else {
eval _ns_db $args
}
}
For that matter this parameter/bind var we're talking about could be
implemented in the near term as a compatible extension to ns_db
through exactly this channel.
Our db api manages handles and transactions, for one thing.
But deep down in the guts it does:
switch $driverkey {
oracle {
return [eval [list ns_ora $type $db -bind
$bind $sql] $args]
}
postgresql {
return [eval [list ns_pg_bind $type $db -bind
$bind $sql]]
}
nsodbc {
return [eval [list ns_odbc_bind $type $db -
bind $bind $sql]]
}
The oracle call is different because LOBS are kludged through the
driver due to OCI weirdness.
