💖 FirebirdEmbedded(3pm) — bestie edition 💖

okay so you found the FirebirdEmbedded(3pm) page, and honestly? it's giving main character of the "no server needed" cinematic universe. sit down, get comfy, let's go 🫶

✨ NAME ✨

DBD::FirebirdEmbedded — embedded Firebird server (and client). yes, BOTH. it's an overachiever and we love that for it 💅

---

🌸 SYNOPSIS 🌸

use DBI;

$dbh = DBI->connect("dbi:FirebirdEmbedded:db=$dbname", undef, undef);

# See the DBI module documentation for full details

no cap, that's the whole vibe. also, lowkey important: go peek at the DBI module documentation for the full deets, because this page is not about to re-explain DBI to you 💀

---

🦋 DESCRIPTION 🦋

DBD::FirebirdEmbedded is a variant of DBD::Firebird, except it's linked against the Firebird embedded library, libfbembed. iconic behavior.

so here's the tea: it can still talk to remote Firebird servers (because it's also linked with the Firebird client library, libfbclient — she contains multitudes ✨), AND it can work with Firebird databases with no dedicated Firebird server at all. zero. zilch. the server is just… inside the library. obsessed.

🎀 but first, set these up, bestie 🎀

• Username/password — these should be unset. both in the DBI->connection(...) call and in the environment (the ISC_USER, ISC_PASSWORD, DBI_USER, and DBI_PASSWORD variables). unset them. fr fr.
• Firebird lock directory — you need to set the FIREBIRD_LOCK environment variable to some place where the process can write. 🚨 and listen: if you're planning for several processes to access the database file directly, they all need FIREBIRD_LOCK set to the same directory, or else database corruption will occur. that's not a vibe, that's a tragedy.
• No host in the DSN — obviously, don't set any host when calling DBI->connection(...). not even localhost. not even as a lil treat. 🙈
• Permissions to read/write the database — obviously, the process needs to be able to read/write the database file. like, that one's kind of self-explanatory but here we are.

👑 COMPARISON WITH DBD::FIREBIRD 👑

DBD::FirebirdEmbedded provides exactly the same functionality as the Firebird server of the same version as the libfbembed library. so it's not a diet version, it's the full meal.

and it can still work with remote databases — in that case, the usage is exactly the same (same DSN, same environment) as with the regular DBD::Firebird. no extra hoops, no new syntax, we love consistency 💜

⭐ Pros

• Standalone work with Firebird databases — no need to set up or administer a Firebird server. all the server functionality is available through the libfbembed library. shared access to databases is still possible (but go read "Firebird lock directory" above — seriously, go read it). 🫶
• No network latency — working directly with the database file eliminates possible network delays, even if the server is on the local host. it's giving speed, it's giving efficiency. 🔥

💀 Cons

• Memory footprint — the libfbembed library contains a fully functional Firebird server, so it's bigger than the ordinary client library, libfbclient. she's thicc. that's the price of greatness. 😭
• Setup complexity — it is very important to make sure that all processes that access a given database use the same lock directory. see "Firebird lock directory" above. this is the one thing you cannot skip, bestie.
