What is your field?

Variables, operators, if, loops and your first try/exception: learn MQL step by step.

Atom lists, data types, constants, translations, session variables and error patterns.

Typed scripts, execute / call / include, generated calls and URLs, parameters and logs.

Calendars, business days, time zones, ISO and epoch, durations, quarters and week numbers.

Cleaning, case styles, regex, URL/HTML/Base64 encodings, number bases and encryption.

IBAN, BIC, SIRET, Luhn, email, IP, UUID, JSON and date checks gathered in a validation report.

In-memory JSON documents, persistent nodes and sequences: build, walk, sort, clean up.

Full script lifecycle in the MQL editor: typed parameters, read back, generate, patch, deploy, copy, grant, delete.

execute, call, include, sub_include, parallel, stack: which environment, which checks, which logs.

A small REST resource with get, post, put and delete scripts: validation, JSON answers, codes, grants, URLs and API docs.

Asynchronous processing with the stack: push runs now or later, priorities and parallel limits, errors and replays, flows and cleanup.

Cron jobs and delayed runs: add, resume, pause, update and remove jobs, prove they ran, and postpone stack runs with a delay condition.

Event-driven scripts: file watchers that push each file event to the stack, validation, archiving, errors and safe restarts.

Parameters (private, described, locked, deployed), environment variables, sessions and connections used by your scripts.

Group your scripts, commit, compare, roll back, export, import and package a release.

Coded errors with try/exception, logs with correlation ids, timing, metrics and defensive checks.

Connections, DDL and DML with sql encode, transactions, cursors, parse, and exports to JSON, CSV, Excel and PDF on a real local database. Run the recipes in order: the first one creates the tuto_db_h2 database.

Generate SCRUD scripts from a table, patch and install them, write typed read and write APIs, check data quality and manage connections per environment. Uses the tuto_db_h2 database of the SQL developer recipes; the last recipe removes it.
