如何在MySQL中加入这5张表？

Question

I have 5 tables that I need to connect to get the necessary data.

Table1

id | number
1  | 1
2  | 5

Table 2

id | number | user_id
1  | 1      | 9
2  | 5      | 8

Table 3

id | name | 
8  | john | 
9  | jane | 

Table 4

id | email
6  | johndoe@example.com

Table 5

id | table4_id | table3_id
1  | 6         | 8

Table 1 is my main table and I want to add the name and email from table 3 and 4 respectively to my select query of table 1, but in order to do so, I would need to use table 2 and 5 to connect them as there is no direct relationship between table 1 and table 3 and 4. I only know how to join 3 tables and not 5 tables and it seems confusing to me on how to proceed with this.

I followed the link here to join Table 1,2 and 3. But I don't know how to proceed with table 4 and 5.

This is the query I tried:

SELECT table1.number, table2.number, table2.user_id, table3.id, table3.name,
table4.id, table4.email, table5.table4_id, table3_id
FROM table1
LEFT JOIN table2
    INNER JOIN table3
        //this query will work if I don't include this 2 inner joins
         INNER JOIN table4
            INNER JOIN table5
            ON table3.id = table5.table3_id
         ON table5.table4_id = table4.id
       //
      ON table2.user_id= table3.id
ON table2.number = table1.number;

ERROR: (if included the inner join for table 4 and 5)

Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ON table2.user_id= table3.id

Answer 1

The right Syntax is select .. from .. join .. on .. join ..on ....

SELECT table1.number, table2.number, table2.user_id, table3.id, table3.name,  table4.id, table4.email, table5.table4_id, table3_id
FROM table1
LEFT JOIN table2 ON table2.number = table1.number
INNER JOIN table3 ON table2.user_id= table3.id
INNER JOIN table5 ON table3.id = table5.table3_id
INNER JOIN table4 ON table5.table4_id = table4.id

Answer 2

Try with the below structure. I made it from the structure you given in question

select t1.number, t2.number, t2.user_id, t3.id, t3.name,t4.id, t4.email, t5.t4_id, t3_id 
from table5 as t5 
join table4 as t4 on t5.table4_id = t4.id 
join table3 as t3 on t5.table3_id=t3.id 
join table2 as t2 on t2.user_id = t3.id 
join table1 as t1 on t2.number=t1.number

Answer 3

Try Below code. Hope this will work.

Select t3.name,t4.email,t1.number,t2.user_id 
from table3 t3 JOIN table5 t5 ON t3.id=t5.table3_id 
JOIN table4 t4 ON t4.id=t5.table4_id
JOIN table2 t2 ON t2.user_id=t3.id
JOIN table1 t1 ON t1.number=t2.number;
