USE database_name GO SELECT tab.name AS tableName, col.name AS column_name, per.value AS column_comment, col.is_identity AS column_key, type.name AS data_type, col.max_length AS column_length FROM sys.columns col INNER JOIN sys.tables tab ON col.object_id = tab.object_id LEFT JOIN sys.extended_properties per ON col.column_id = per.minor_id AND per.major_id = tab.object_id INNER JOIN sys.types type ON col.user_type_id = type.user_type_id ORDER BY tab.name, col.is_identity DESC二、查出某个库的所有字段说明(查出数据详细格式化版)
