Left
Left 英音:[left]美音:[lɛft]
功能得到字元串左部指定个数的字元。
语法Left (string,n)
参数string:string类型,指定要提取子串的字元串n:long类型,指定子串长度返回值String。函式执行成功时返回string字元串左边n个字元,发生错误时返回空字元串("")。如果任何参数的值为NULL,Left()函式返回NULL。如果n的值大于string字元串的长度,那幺Left()函式返回整个string字元串,但并不增加其它字元。
例如,在学生课表course中,分别有cno,cname,cpno,credit四列。其中有一项记录为:1,资料库,5,4。在SQL分析器中输入:
INSERT course
(cno,cname,cpno,credit)
select'0001'+left(cno,1),cname,cpno,credit
from course
go
此时course表中会多出一条记录:00011,资料库,5,4。
LEFT
根据所指定的字元数,LEFT 返回文本字元串中第一个字元或前几个字元。
LEFTB 基于所指定的位元组数返回文本字元串中的第一个或前几个字元。
要点 函式 LEFT 面向使用单位元组字元集 (SBCS) 的语言,而函式 LEFTB 面向使用双位元组字元集 (DBCS) 的语言。您计算机上的默认语言设定对返回值的影响方式如下:
- 无论默认语言设定如何,函式 LEFT 始终将每个字元(不管是单位元组还是双位元组)按 1 计数。
- 当启用支持 DBCS 的语言的编辑并将其设定为默认语言时,函式 LEFTB 会将每个双位元组字元按 2 计数,否则,函式 LEFTB 会将每个字元按 1 计数。
支持 DBCS 的语言包括日语、中文(简体)、中文(繁体)以及朝鲜语。
语法
LEFT(text,num_chars)
LEFTB(text,num_bytes)
Text 是包含要提取的字元的文本字元串。
Num_chars 指定要由 LEFT 提取的字元的数量。
- Num_chars 必须大于或等于零。
- 如果 num_chars 大于文本长度,则 LEFT 返回全部文本。
- 如果省略 num_chars,则假设其值为 1。
Num_bytes 按位元组指定要由 LEFTB 提取的字元的数量。
