问题描述

我有2个表,我想用一个存储过程从两个表中检索数据。



第二个表有多行链接到一个排在第一桌。



表1



Field 1 < br $>
Field 2

Field 3



表2



Field 1_1

Field 2_1

Field 3_2

Field 4_2

Field 5_3

Field 6_3



表格通过PK和FK链接



字段1_1,指第二个表字段(字段1)链接到第一个表字段(_1)



我的问题是...我想从单个存储过程查看两个表中的数据,当我执行存储过程时,结果应如下所示:



字段1 - Field 1_1

Field 1 - Field 2_1

Field 2 - Field 3_2

Field 2 - Field 4_2

等等...


到目前为止我尝试了什么...



I have 2 tables, I want to retrieve the data from both tables with a single stored procedure.

The 2nd table has multiple rows that link to a single row in the 1st table.

Table 1

Field 1
Field 2
Field 3

Table 2

Field 1_1
Field 2_1
Field 3_2
Field 4_2
Field 5_3
Field 6_3

The tables are linked via a PK and FK

Field 1_1, refers to the 2nd tables field (Field 1) linking to the 1st tables field (_1)

My question is ... I would like to view data from both tables from a single stored procedure, when i execute the stored procedure the result should be as follows:

Field 1 - Field 1_1
Field 1 - Field 2_1
Field 2 - Field 3_2
Field 2 - Field 4_2
etc...

What i have tried so far...

Create Proc usp_Test
As
Select t1.Field1, t1.Field2, t1.Field3, t2.Field1, t2.Field2, t2.Field3, etc
From tbl_Table1 t1 right outer join tbl_Table2 t2 on t1.PK = t2.FK







请帮忙......




Please help...

推荐答案

我认为可以通过使用来实现简单INNER JOIN



I think that can be achieved by using simple INNER JOIN

SELECT
TABLE1_FIELD, TABLE3_FIELD
FROM TABLE1
INNER JOIN TABLE2 ON TABLE1_FIELD = TABLE2_FIELD


Create Proc usp_Test
As
Select t1.Field1, t1.Field2, t1.Field3, t2.Field1, t2.Field2, t2.Field3, etc
From tbl_Table1 t1 left outer join tbl_Table2 t2 on t1.PK = t2.FK
Order By t1.Field1
