sqlsim

Run SQL scripts and ad-hoc queries against the Ward General Azure SQL Hyperscale database (and any SQL Server / Azure SQL) for the hyperscale-developer talk, using the sqlsim.exe bundled in this kit. Use when: deploying the sql/ scripts, running a quick query against wardgeneral, connection testing, or driving a multi-threaded / scale workload. Full Microsoft Entra support (token, interactive, managed identity) — the passwordless path that works when sqlcmd -G fails.

# sqlsim — bundled SQL runner for the hyperscale-developer talk This kit ships its own copy of `sqlsim.exe` so the whole presentation folder is self-contained (the tool's source repo is not public). It is a standalone, xcopy-deploy executable — the only dependency is **ODBC Driver 18 for SQL Server**. Use this instead of `sqlcmd -G` (Entra-integrated `sqlcmd` fails on some machines with "unknown error"). sqlsim's token path is the reliable passwordless option. ## Path (relative to the presentation root) ``` .\utilities\sqlsim\sqlsim.exe ``` Run commands from `presentations/hyperscale-developer/`, or substitute the full path. ## Live talk environment - Server: `collierhealth-17.database.windows.net` - Database: `wardgeneral` (Hyperscale HS_Gen5_8) - Auth: Microsoft Entra as `bobward@microsoft.com` ## Entra authentication (choose one) - `-T <token>` — Azure access token (most reliable; see example below) - `-A` — Entra interactive (`ActiveDirectoryInteractive`, default) - `-A ActiveDirectoryMsi` — managed identity (e.g. from App Service) - `-E` — Windows integrated (local SQL Server only) ## Common commands ```powershell # Ad-hoc query against wardgeneral via Entra token (the reliable path) $token = (az account get-access-token --resource https://database.windows.net/ --query accessToken -o tsv) & '.\utilities\sqlsim\sqlsim.exe' -S collierhealth-17.database.windows.net -d wardgeneral -T $token -Q "SELECT @@VERSION" # Deploy a schema/seed script (GO batch separators handled natively) & '.\utilities\sqlsim\sqlsim.exe' -S collierhealth-17.database.windows.net -d wardgeneral -T $token -i .\build\sql\05-seed.sql # Entra interactive (no token needed, pops a browser) & '.\utilities\sqlsim\sqlsim.exe' -S collierhealth-17.database.windows.net -d wardgeneral -A -Q "SELECT DB_NAME()" # Multi-threaded scale workload: 16 threads x 100 iterations, quiet, with server stats & '.\utilities\sqlsim\sqlsim.exe' -S collierhealth-17.database.windows.net -d wardgeneral -T $token -i .\workload.sql -n 16 -r 100 -q -querystats ``` ## Notes - `-q` quiet (metrics only), `-v` verbose, `-json` machine-readable, `-o <file>` tee output. - `-R` read-only intent (route to an HA secondary) — for the "Make it HA" beat. - `-Q`, `-i`, and `-workload` are mutually exclusive query sources. - Exit code 0 = success, 1 = error. Full parameter reference lives next to the binary: `utilities/sqlsim/sqlsim-usage.md`.
