你可以使用的另一种方式是这样的查询:

SELECT DISTINCT
    LTRIM(m.n.value('.[1]','varchar(8000)')) as columnName
FROM 
    (SELECT CAST('<XMLRoot><RowData>' + REPLACE(t.val,',','</RowData><RowData>') + '</RowData></XMLRoot>' AS XML) AS x
     FROM (SELECT '1, 1, 1, 2, 5, 1, 6') AS t(val)
    ) dt
  CROSS APPLY 
    x.nodes('/XMLRoot/RowData') m(n);

如果您只想从单个表中选择某些值，您可以尝试这样做

select distinct(*) from table_name where table_field in (1,1,2,3,4,5)

eg:

select first_name,phone_number from telephone_list where district id in (1,2,5,7,8,9)

如果你想从多个表中选择，那么你必须选择UNION。

如果你只是想选择值1,1,1,2,5,1,6，那么你必须这样做

select 1 
union select 1 
union select 1 
union select 2 
union select 5 
union select 1 
union select 6

这适用于SQL Server 2005，如果有最大数量:

SELECT * 
FROM
  (SELECT ROW_NUMBER() OVER(ORDER BY a.id) NUMBER
  FROM syscomments a
  CROSS JOIN syscomments b) c
WHERE c.NUMBER IN (1,4,6,7,9)

PostgreSQL提供了两种方法:

SELECT DISTINCT * FROM (VALUES('a'),('b'),('a'),('v')) AS tbl(col1)

or

SELECT DISTINCT * FROM (select unnest(array['a','b', 'a','v'])) AS tbl(col1)

使用数组方法，你也可以这样做:

SELECT DISTINCT * FROM (select unnest(string_to_array('a;b;c;d;e;f;a;b;d', ';'))) AS tbl(col1)

如果你需要一个数组，用逗号分隔数组列:

SELECT * FROM (VALUES('WOMENS'),('MENS'),('CHILDRENS')) as X([Attribute])
,(VALUES(742),(318)) AS z([StoreID])

使用SQL In函数

就像这样:

SELECT * FROM mytable WHERE:
"VALUE" In (1,2,3,7,90,500)
