SQL MySQL

Contract

Prereqs:

• bash available on PATH.
• mysql client available on PATH (or install via Homebrew; this skill will try to add mysql-client/bin to PATH when available).
• Connection settings provided via exported env vars and/or an env file.

Inputs:

• --prefix <PREFIX>: env var prefix (example: QB → QB_MYSQL_HOST, QB_MYSQL_PORT, ...).
• --env-file <path>: file to source for env vars (use /dev/null to rely on already-exported env vars).
• One of:
  • --query "<sql>" (maps to mysql -e)
  • --file <file.sql> (runs file via stdin redirection)
  • -- <mysql args...> (pass-through to mysql)
