Question

我的表格包含以下数据

 ID  | Name
 --- | ---------
 1   | Apple
 2   | Microsoft
 3   | Samsung       and so on...

就我而言，输入是＆＃39; 1,2,3＆＃39;。

我需要的输出是＆＃39; Apple,Microsoft,Samsung＆＃39;。

Answer 1

SELECT STUFF((
       SELECT ','+ Name 
       FROM MyTable
       WHERE ID in (1, 2, 3)
       FOR XML PATH('')
    ), 1, 1, '') AS Names

结果：

苹果，微软，三星

Answer 2

您可以使用package collectionFramework; import java.util.Iterator; import java.util.LinkedList; public class LinkedListDemo{ public static void main(String[] args) { Demo obj = new Demo(); obj.addToList(); obj.displayList(); } } class Demo{ LinkedList<String> al; Iterator<String> itr; Demo(){ al = new LinkedList<String>(); itr = al.iterator(); } void addToList(){ al.add("Aniruddha"); al.add("Hitesh"); al.add("Rahul"); al.add("Kshitij"); } void displayList(){ while(itr.hasNext()){ System.out.println(itr.next()); } } }

XML PATH

结果看起来像SELECT ( SELECT T.Name + ', ' FROM Tbl T WHERE Id in (1, 2, 3) FOR XML PATH ('') ) DesiredOutput

Answer 3

USE [Database Name]

SELECT COLUMN_NAME,* 
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'YourTableName'

由于SQL服务器在运行时不支持输入，您可以创建存储过程并在执行时传递输入值。或者只是运行以下查询。
