Hi all,

我将a和b传递给SP，我想保存在数据库中，例如

I am passing a and b to SP and I want to save in DB like

a   b
1  admin
2  admin
3  admin
4  admin

how can we do it?

推荐答案

SQL没有数组的概念，因此有点儿麻烦.
将列表作为字符串参数传递:

SQL doesn''t have a concept of arrays, so this gets a bit fiddly.
Pass a list as a string parameter:

DECLARE @INSTR as VARCHAR(MAX)
SET @INSTR = '2,3,177,'
DECLARE @SEPERATOR as VARCHAR(1)
DECLARE @SP INT
DECLARE @VALUE VARCHAR(1000)
SET @SEPERATOR = ','
WHILE PATINDEX('%' + @SEPERATOR + '%', @INSTR ) <> 0 
BEGIN
   SELECT  @SP = PATINDEX('%' + @SEPERATOR + '%',@INSTR)
   SELECT  @VALUE = LEFT(@INSTR , @SP - 1)
   SELECT  @INSTR = STUFF(@INSTR, 1, @SP, '')
   INSERT INTO myTable (a, b) VALUES (@VALUE, 'admin')
END
