sqlalchemy-azure-sql

Uses SQLAlchemy correctly against Azure SQL Database, where the dialect appends an OUTPUT clause to INSERT statements and that single clause explains two failures agents never connect: a hard error on any table carrying a trigger, and fast_executemany appearing to do nothing. Use when a user says "SQLAlchemy with Azure SQL", "mssql+pyodbc", "implicit_returning", "fast_executemany", "insertmanyvalues", "Alembic against Azure SQL", or pastes "the target table of the DML statement cannot have any enabled triggers if the statement contains an OUTPUT clause without INTO clause". Also use when an ORM insert fails on one table only, or a bulk load is no faster after fast_executemany was set. Covers the engine URL, the generated DML, type mapping and Alembic. Driver choice is connect-from-python and retry connect-to-azure-sql.
