因此,在多字节格式中所需要的字节数取决于长度值。
Therefore, the number of bytes required in multi-byte format depends upon the length value.
回想在本系列第一篇文章中的讨论,在希望使用多字节整数格式的时候,必须将第一个长度字节的最左边一位设置为1。
Recall from the discussion in the first article of this series that whenever I want to use multi-byte integer format, I must set the leftmost bit of the first length byte to 1.
LVARCHAR (IDS)存储可变长度的单字节或多字节文本字符串(最高可达32,739个字节)。
LVARCHAR (IDS) Stores single-byte or multibyte text strings of varying length (up to 32,739 bytes).
回想一下在本系列的第一篇文章中对表2的讨论,有两种表示字节长度的方法:单字节表示法和多字节表示法。
Recall from the discussion of Table 2 in the first article of this series that there are two ways of representing length bytes: single-byte length notation and multi-byte length notation.
但是对于多字节编码,字符的字节长度随使用编码模式的不同而不同,每个字符的长度可能是一个字节或多个字节。
However, in the case of a multi-byte encoding, the length of the character in bytes varies according to the encoding used, and each character can be one or more bytes in length.
VARCHAR存储可变长度的单字节或多字节文本字符串(最高可达255个字节);在整理文本数据时支持使用代码集顺序。
VARCHAR Stores single-byte or multibyte text strings of varying length (up to 255 bytes); supports code-set order collation of text data.
CHAR存储固定长度的单字节或多字节的文本字符串(最高可达32,767个字节);在整理文本数据时支持使用代码集顺序。
CHAR Stores single-byte or multibyte text strings of fixed length (up to 32,767 bytes); supports code-set order in collation of text data.
CHAR存储固定长度的单字节或多字节的文本字符串(最高可达32,767个字节);在整理文本数据时支持使用代码集顺序。
CHAR Stores single-byte or multibyte text strings of fixed length (up to 32,767 bytes); supports code-set order in collation of text data.
