the length of each one of these columns must still fall within the limit of 8, 000 bytes per row; however, their combined widths can exceed the 8, 060-byte limit 这些列中每一列的长度仍然必须在每行8000字节的限制内,但它们的合并宽度可以超过8060字节的限制。
data types . if the combined widths of these variable-length columns cause the row to exceed the page size limit, the database engine may move data from variable-length columns to separate pages 如果这些长度可变列的组合宽度导致行超出页大小的限制,那么数据库引擎可能将数据从长度可变的列移到单独的页中。
data of type varchar, nvarchar, varbinary, or sql variant that is stored off the main data page of a table or index because the combined widths of these columns exceeds the limit of 8, 060 bytes per row 为特定目的(例如搜索、排序和重新组合数据)而组织和表示的信息、表和其他对象的集合。数据库存储在文件中。
