Detailed Description

Exception thrown when applying or reverting a single migration fails.

Carries structured diagnostic context so callers (CLI, GUI) can render the which migration, which step, which SQL statement and the underlying driver error as separate fields instead of parsing one opaque message string.

Constructor & Destructor Documentation

MigrationException()

Lightweight::SqlMigration::MigrationException::MigrationException	(	Operation	operation,
		MigrationTimestamp	timestamp,
		std::string	title,
		std::size_t	stepIndex,
		std::string	failedSql,
		SqlErrorInfo	driverError
	)

Constructs a migration exception that wraps a driver error with the migration identity and the exact SQL statement that failed.

Parameters

operation	Whether the failure happened during apply or revert.
timestamp	The migration that failed.
title	Human-readable migration title.
stepIndex	Zero-based step index inside the migration plan.
failedSql	The SQL statement that produced the driver error.
driverError	The ODBC-level error info as received from the driver.
