JOIN => Add USING statement

[abbadon1334]

In PHP 7.1.15 if you do something like :
SQL :
SELECT
tbl_a.col_a, tbl_a.col_b,
tbl_b.col_ba, tbl_b.col_bb
FROM tbl_a
LEFT JOIN tbl_b ON (tbl_a.ID = tbl_b.ID)

results will be nulled for all tbl_b columns

with USING this problem is solved.

it works but i don't like my conditional : strpos(array_values($val)[0],'.')

@abbadon1334 I will investigate the USING statement.

However, the PHP count and strpos functions are very slow. I try to not use them entirely, as inserting only a couple slows things dramatically. I will try to find alternative ways to do this.
