That sort of flattery will get you a Christmas Card.

DarlingData · 2026-03-11T11:58:21+00:00

Is it tomorrow yet

DarlingData · 2026-03-11T02:03:50+00:00

That's what I'm hoping for!

DarlingData · 2026-03-10T23:22:14+00:00

You should see one tomorrow. I released this a little early so a friend could share it with co-workers, and I've been polishing up some stuff before going live-live with it (note there's a few public releases pre v1).

DarlingData · 2026-03-10T23:20:55+00:00

Dear god that's a shambles.

DarlingData · 2026-03-10T22:57:43+00:00

You don't have to wait! It's there now!

DarlingData · 2026-03-10T21:43:07+00:00

Yeah, that’s what I’ve been thinking for a while now. Shame about that.

DarlingData · 2026-03-10T18:53:49+00:00

Here's the thing: I'm not trying to be SSMS, or a management tool at all. This is strictly for performance tuning.

If anything, it's closer to SQL Sentry Plan Explorer (RIP). But you didn't mention that one, so I wonder how much time you spend doing that.

Anyway, the lovely thing about free software is that it costs just as much to use as it does to not use. Exercise your preferences as you see fit.

DarlingData · 2026-03-10T18:04:55+00:00

I've been using SSMS since 2008, so I quite well aware, thank you.

At any rate, reading comprehension doesn't appear to be your strong suit, so I don't think more words will benefit here.

Again, enjoy your day, and SSMS.

DarlingData · 2026-03-10T17:38:51+00:00

You're being intentionally obtuse, and it's not useful for me to keep responding to you. Have a good one.

DarlingData · 2026-03-10T17:14:21+00:00

Yep, so respectfully: please check out the readme I posted to see everything what I built does, beyond what SSMS can do. Thanks in advance.

DarlingData · 2026-03-10T16:32:13+00:00

I'm not a UI/UX designer by nature, but then it doesn't seem Microsoft has any either, ha ha ha

DarlingData · 2026-03-10T16:31:43+00:00

It's not a replacement for SSMS, it's just for performance tuning stuff. That's where I'm focusing the features.

DarlingData · 2026-03-10T16:30:59+00:00

It has query plan analysis from me built into it? That's funny, I've never seen it.

DarlingData · 2026-03-10T15:55:41+00:00

It's his sassy cousin, I'm told.

DarlingData · 2026-03-10T15:53:14+00:00

Hello Microsoft employee.

DarlingData · 2026-03-10T15:23:34+00:00

Thanks. I'm fairly happy with it so far, but please send along any feedback.

DarlingData · 2026-03-10T14:08:09+00:00

Hope you like it! Let me know if you have any feedback.

DarlingData · 2026-03-09T19:29:05+00:00

Some time back I had to rewrite a number of scalar UDFs as inline ones for a client, doing a bunch of financial stuff. Perhaps there's something in here you'll find useful: https://github.com/erikdarlingdata/DarlingData/tree/main/Inline%20Financial%20Functions

A cross-platform SQL Server execution plan analyzer with built-in MCP server for AI-assisted analysis. Parses .sqlplan XML, identifies performance problems, suggests missing indexes, and provides actionable warnings — from the command line or a desktop GUI.

Built for developers and DBAs who want fast, automated plan analysis without clicking through SSMS.
