إعدادات التنسيق

إذا كان الإعداد input_format_with_names_use_header مضبوطًا على 1، فستُطابَق الأعمدة الواردة في بيانات الإدخال مع أعمدة الجدول بناءً على أسمائها، وسيتم تخطي الأعمدة ذات الأسماء غير المعروفة إذا كان الإعداد input_format_skip_unknown_fields مضبوطًا على 1. وإلا فسيتم تخطي الصف الأول. إذا كان الإعداد input_format_with_types_use_header مضبوطًا على 1، فستُقارَن الأنواع الواردة في بيانات الإدخال بأنواع الأعمدة المقابلة في الجدول. وإلا فسيتم تخطي الصف الثاني.
