Question

这是复制记录的查询

CREATE TABLE test(
    id int,
    name varchar(20),
    nameID int
);

insert into test
values(1,'test1',1),
      (1,'test2',2),
      (1,'test3',3),
      (1,'test4',4),
      (1,'test5',5)

select 
    t1.name,
    t2.name
from 
    (select * from test where nameID in (1,2)) t1 left join 
    (select * from test where nameID in (3,4,5)) t2 on t1 .id = t2.id

当前输出为

test1 test3
test1 test4
test1 test5
test2 test3
test2 test4
test2 test5

但是我想在SSRS中显示的是

test1 test3
test4
test2 test5

基本上，在每个id组中，我只想显示不同的值。（背后的逻辑是一个id组（一个文档）可以有多个批准者和soignee）到目前为止，我一直没有运气尝试HideDuplicates和group。

你在这里

CREATE TABLE test(
    id int,
    name varchar(20),
    nameID int
);

insert into test
values(1,'test1',1),
      (1,'test2',2),
      (1,'test3',3);

SELECT T2.Name, T1.Name
FROM Test T1 LEFT JOIN
     (SELECT * FROM Test WHERE NameID IN (1, 3)) T2 
ON T1.NameID = T2.NameID;

或

SELECT T1.Name, T2.Name
FROM Test T1 LEFT JOIN
     (SELECT * FROM Test WHERE NameID % 2 = 1) T2 
ON T1.NameID = T2.NameID;

结果：

+-------+-------+
| Name  | Name  |
+-------+-------+
| test1 | test1 |
| test2 |       |
| test3 | test3 |
+-------+-------+

在组SSRS中显示不同的行
