小编use*_*110的帖子

嗨,我有一个列与列

id desc rate  rates_id

1   NYC  0.1    0001
2   NYC  0.25   0003
3   KYC  0.12   0001
4   KYC  0.15   0003

我需要以这种方式显示行

desc  rate where rates_id = 0001  rate where rates_id=0003
NYC    0.1                        0.25
KYC    0.12                       0.15

我讨论了这个问题,但没有工作

SELECT desc,
       rate,
       (SELECT rate
        FROM   tablea p
        WHERE  rates_id LIKE '0003'
               AND p.desc = t.desc) AS rate2
FROM   tablea t
WHERE  rates_id LIKE '0001';  

任何暗示???

我有这个字符串

 Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"

并想要检索一个字符串

newstr = 12,32,15,16,14

我试过这么多

Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"
Dim word As String
Dim uc As String() = test.Split(New Char() {","c})
For Each word In uc
' What can i do here?????????
Next

只有唯一的数字我怎么能在vb asp.net中做到这一点

正确答案

Dim test As String = "12,32,12,32,12,12,32,15,16,15,14,12,32"
                Dim word As String
                Dim uc As String() = test.Split(New Char() {","c}).Distinct.ToArray
                Dim sb2 As String = "-1"
                For Each word In uc
                    sb2 = sb2 + "," + …
