It gives double the LENGTH function value if double-byte data type is used as input.
如果使用双字节数据类型作为输入，它就会给出双倍的length函数值。
Null and default value Compression (V8 GA) : Compression for null, zero length data in variable length columns and system default value.
null值和缺省值压缩(V 8GA)：对变长列中的零长度空数据和系统缺省值进行压缩。
The parsing overhead is a result of having to read and evaluate the tags and length fields in the message to determine how to handle the data value following the tag.
解析开销是因为必须计算消息中的标记和长度字段以便决定如何处理标记后面的数据值而造成的。
If the length value is greater than 127, I have to use multi-byte length notation, which USES at least 2 bytes of data.
如果长度值大于127，那么我必须使用多字节长度表示法，它至少使用2字节数据。
The run length encoding (RLE) compression algorithm requires very little processor time and works well for data that has lots of the same byte value repeated in consecutive locations.
行程编码(RLE)压缩算法需要非常少的处理器时间，适用于在连续位置重复许多相同字节值的数据。
Attribute validators verify that a single attribute is set to a valid value, length, format, or data type.
Attribute确认器会证实单个的属性会设置为一个有效的值，长度，格式，或者数据类型。
Message digests are secure one-way hash functions that take arbitrary-sized data and output a fixed-length binary hash value.
消息摘要是安全的单向哈希函数，它可以接受任意大小的输入数据，并输出固定长度的二进制哈希值。
If the internal representation of the spatial value requires less bytes than specified in the inline length setting, then it will be stored inline as VARCHAR FOR BIT DATA.
如果空间值的内部表示需要的字节数少于inlinelength设置中指定的值，那么它将以内联(inline)的方式存储为VARCHAR FORBIT DATA。
A hash value is a numeric value of a fixed length that uniquely identifies data.
杂凑值是唯一识别资料的固定长度数值。
