Question

See more:

CREATE TABLE `Teste01` (
	`id_01`	INTEGER,
	`id_02`	INTEGER,
	PRIMARY KEY(`id_02`)
);

CREATE TABLE `Teste02` (
	`id_001`	INTEGER,
	`id_primary`	INTEGER,
	PRIMARY KEY(`id_primary`)
);

<pre>CREATE TABLE `Teste03` (
	`id_003`	INTEGER,
	`id_primary`	INTEGER,
	PRIMARY KEY(`id_primary`)
);

What I have tried:

select teste01.id_01, teste02.id_002, teste03.id_003 from teste01 inner join teste02 on teste01.id_01=teste02.id_primary;

So, how I make a inner join with three tables?

Thanks.

Solution 1

SQL

SELECT t1.[id_01]
     , t2.[id_002]
     , t3.[id_003]
  FROM [dbo].[Teste01] t1
    LEFT JOIN [dbo].[Teste02] t2 ON t2.[id_primary] = t1.[id_01]
    LEFT JOIN [dbo].[Teste03] t3 ON t3.[id_primary] = t1.[id_02];
