Sql server 2005 获取具有列值约束的记录

我有一张像

    Name              Privilege                                                           
     x                   1                                                                
     y                   2                                                                
     x                   3                                                                
     A                   1                                                                

SELECT
    *
FROM
    <table> t
         LEFT JOIN
    <table> t2
         ON
             t.Name = t2.Name and
             t2.Privilege <> 1
WHERE
    t2.Name is null and
    t.Privilige = 1

现在，我只想获取拥有特权1的姓名。 也就是说，它应该是

    Name           Privilege                                                           
     A                1             

SELECT
    *
FROM
    <table> t
         LEFT JOIN
    <table> t2
         ON
             t.Name = t2.Name and
             t2.Privilege <> 1
WHERE
    t2.Name is null and
    t.Privilige = 1

有人能帮我吗

选择
SELECT
    *
FROM
    <table> t
         LEFT JOIN
    <table> t2
         ON
             t.Name = t2.Name and
             t2.Privilege <> 1
WHERE
    t2.Name is null and
    t.Privilige = 1

*
从…起
T
左连接
t2
在…上
t、 Name=t2。名称和
t2.特权1
哪里
t2.名称为null，并且
t、 特权=1

或者，您也可以将其作为NOT EXISTS子句和相关子查询编写

SELECT
    *
FROM
    <table> t
         LEFT JOIN
    <table> t2
         ON
             t.Name = t2.Name and
             t2.Privilege <> 1
WHERE
    t2.Name is null and
    t.Privilige = 1

编辑

SELECT
    *
FROM
    <table> t
         LEFT JOIN
    <table> t2
         ON
             t.Name = t2.Name and
             t2.Privilege <> 1
WHERE
    t2.Name is null and
    t.Privilige = 1

在注释中，您希望找到“匹配此集合，并且仅匹配此集合”-将您的条件放在另一个表中（可能是临时表或表变量），然后开始查看“关系划分”。在谷歌上搜索这个词会得到一个不错的答案。“精确除法”下的示例与您所说的相同。

非常感谢您的回答。如果约束条件发生变化，例如，仅使用特权（1和2）、（1和3）、（1,2和3）获取名称，我如何使用相同的方法。，

SELECT
    *
FROM
    <table> t
         LEFT JOIN
    <table> t2
         ON
             t.Name = t2.Name and
             t2.Privilege <> 1
WHERE
    t2.Name is null and
    t.Privilige = 1

;WITH set1 AS (SELECT * FROM Privileges WHERE Privilege IN (1, 3))
SELECT up.UserId
FROM UserPrivileges up
INNER JOIN set1 ON set1.Privilege = set1.Privilege
GROUP BY up.UserId
HAVING COUNT(up.Privilege) = (SELECT COUNT(*) FROM set1);
