摘要： A method, apparatus, and article of manufacture for accessing data in a computer system. Compression and decompression functions are associated with a column of the table, in order to perform compression of decimal, numeric or date data stored in the column when the data is inserted or updated in the table, and in order to perform decompression of the data stored in the column when the data is retrieved from the table. The compression function compresses and stores the data in a fixed-length compressed field in the column without a length value, and the fixed-length compressed field has a size that is determined by a range of values for the data stored in the fixed-length compressed field. The decompression function retrieves and decompresses the data from the fixed-length compressed field.
摘要翻译：一种用于访问计算机系统中的数据的方法，装置和制品。压缩和解压缩功能与表的列相关联，以便当在表中插入或更新数据时执行存储在列中的十进制，数字或日期数据的压缩，并且为了执行对存储的数据的解压缩在从表中检索数据的列中。压缩功能将数据压缩并存储在列中的固定长度压缩字段中，没有长度值，固定长度压缩字段具有由存储在固定长度中的数据的值的范围确定的大小压缩场。解压缩功能从固定长度压缩字段中检索和解压缩数据。
