先创建一个分割表名的分割函数
--表值函数用以截取字符串
--如果为其添加一列主键id,则其顺序就会固定了
create FUNCTION [Split](@text NVARCHAR(max))
RETURNS @tempTable TABLE(value NVARCHAR(1000))
AS
BEGIN
DECLARE @StartIndex INT --开始查找的位置
DECLARE @FindIndex INT --找到的位置
DECLARE @Content VARCHAR(4000) --找到的值
--初始化一些变量
SET @StartIndex = 1 --T-SQL中字符串的查找位置是从1开始的
SET @FindIndex=0 --开始循环查找字符串逗号
WHILE(@StartIndex <= LEN(@Text))
BEGIN
--查找字符串函数 CHARINDEX 第一个参数是要找的字符串
-- 第二个参数是在哪里查找这个字符串
-- 第三个参数是开始查找的位置
--返回值是找到字符串的位置
SELECT @FindIndex = CHARINDEX(',' ,@Text,@StartIndex)
--判断有没找到 没找到返回0
IF(@FindIndex =0 OR @FindIndex IS NULL)
BEGIN
--如果没有找到就表示找完了
SET @FindIndex = LEN(@Text)+1
END
--截取字符串函数 SUBSTRING 第一个参数是要截取的字符串
-- 第二个参数是开始的位置
-- 第三个参数是截取的长度
SET @Content =SUBSTRING(@Text,@StartIndex,@FindIndex-@StartIndex)
--初始化下次查找的位置
SET @StartIndex = @FindIndex+1
--把找的的值插入到要返回的Table类型中
INSERT INTO @tempTable (Value) VALUES (@Content)
END
RETURN
END
