Maximum number of table joins is 61 as per https://stackoverflow.com/questions/23389820/what-is-the-maximum-number-of-table-joins-in-mariadb Tested out as follows:
1CREATE TABLE t (i INT(10) NOT NULL);
2select *
3from t a01 join t a02 join t a03 join t a04 join t a05 join t a06 join t a07 join t a08 join t a09 join t a10
4join t a11 join t a12 join t a13 join t a14 join t a15 join t a16 join t a17 join t a18 join t a19 join t a20
5join t a21 join t a22 join t a23 join t a24 join t a25 join t a26 join t a27 join t a28 join t a29 join t a30
6join t a31 join t a32 join t a33 join t a34 join t a35 join t a36 join t a37 join t a38 join t a39 join t a40
7join t a41 join t a42 join t a43 join t a44 join t a45 join t a46 join t a47 join t a48 join t a49 join t a50
