契约
- Statement mutation methods are immutable and return clones without modifying the caller instance in place
- Statement::create() triggers E_USER_DEPRECATED directing callers to use new Statement() constructor
- Statement slicing offset skips data rows while getRecords() preserves original reader line offset keys
- ResultSet nth(0) and first() access records by zero-based position within ResultSet rather than CSV record offset
- fetchColumn() returns an Iterator whose converted array retains original reader record offset keys
- select() and selectAllExcept() project specified columns into associative records with projected headers
- andWhere() accepts column, comparison operator string, and value arguments rather than a single callback
