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])

对我来说行之有效的一种技术是查询一个您知道其中有大量记录的表，其中只包括结果中的Row_Number字段

Select Top 10000 Row_Number() OVER (Order by fieldintable) As 'recnum' From largetable

将返回从1到10000条记录的结果集，在另一个查询中使用这个来给你想要的结果

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)

总的来说:

SELECT 
  DISTINCT 
      FieldName1, FieldName2, ..., FieldNameN
FROM
  (
    Values
        ( ValueForField1, ValueForField2,..., ValueForFieldN ),
        ( ValueForField1, ValueForField2,..., ValueForFieldN ),
        ( ValueForField1, ValueForField2,..., ValueForFieldN ),
        ( ValueForField1, ValueForField2,..., ValueForFieldN ),
        ( ValueForField1, ValueForField2,..., ValueForFieldN )
  ) AS TempTableName ( FieldName1, FieldName2, ..., FieldNameN )

在你的情况下:

Select 
  distinct
  TempTableName.Field1 
From 
  (
  VALUES
    (1), 
    (1), 
    (1), 
    (2), 
    (5), 
    (1), 
    (6)
  ) AS TempTableName (Field1)
