I want something like this, not sure if my syntax is correct though. I will be executing this with php.
SELECT
a.column1,
a.column2,
b.column1,
c.column1,
IF a.column3 NOT NULL
THEN (
SELECT c.column1, c.column2, c.column3, d.column1
FROM table_d d
INNER JOIN table_c c
ON d.column1 = c.column1 AND c.column4 = 1
WHERE d.column2 = a.column3
);
END IF;
FROM table_a a
INNER JOIN table_b b
ON a.column1 = b.column1 AND b.column2 = 1
INNER JOIN table_c c
ON a.column1 = c.column1 AND c.column2 = 1
WHERE
a.column1 = 1000
AND b.column3 = 1
AND c.column3 = 0
ORDER BY
a.column1 ASC
So the output will be something like this:
It would be ok if it has multiple rows with the same data on the first few columns. Something like this:
grey area is from the outer SELECT and white area is from the inner SELECT
Note that both outer and inner select statement has table_c. If without the IF statement, can I do this?
SELECT
a.column1,
a.column2,
b.column1,
c.column1,
cc.column1,
cc.column2,
cc.column3,
d.column1
FROM table_a a
INNER JOIN table_b b
ON a.column1 = b.column1 AND b.column2 = 1
INNER JOIN table_c c
ON a.column1 = c.column1 AND c.column2 = 1
LEFT JOIN table_d d
ON a.column3 = d.column2
INNER JOIN table_c cc
ON d.column1 = cc.column1 AND cc.column4 = 1
WHERE
a.column1 = 1000
AND b.column3 = 1
AND c.column3 = 0
ORDER BY
a.column1 ASC
It kinda feels wrong to me.
What if I use fetch_assoc?
Is it even possible to do this in one query?

To select multiple values, you can use where clause with OR and IN operator.
To select more than one row in the data view, click one row, then hold the Control (Windows) or Command (Mac) key and select each of the other rows you wish to edit or remove. To select a continuous list, click one row, then hold the Shift key and click the last row.
Select multiple items in a table or list using shift-click and ctrl-click. This can be useful to add multiple resources to a graph or modify multiple items at a time. To select a range of items, hold down the shift key and then click on the top item followed by the bottom item.
Try something like this:
SELECT
a.column1,
a.column2,
b.column1,
c.column1,
IF (a.column3 NOT NULL,c_2.column1,''),
IF (a.column3 NOT NULL,c_2.column2,''),
IF (a.column3 NOT NULL,c_2.column3,''),
IF (a.column3 NOT NULL,d.column4,'')
FROM table_a a
INNER JOIN table_b b
ON a.column1 = b.column1 AND b.column2 = 1
INNER JOIN table_c c
ON a.column1 = c.column1 AND c.column2 = 1
INNER JOIN table_c as c_2
ON d.column1 = c.column1 AND c.column4 = 1
INNER JOIN table_d
ON a.column1 = c.column1 AND c.column2 = 1
WHERE
a.column1 = 1000
AND b.column3 = 1
AND c.column3 = 0
ORDER BY
a.column1 ASC
