MySQL update a joined table

Question

I want to update a table in a statement that has several joins. While I know the order of joins doesn\'t really matter (unless you you are using optimizer hints) I ordered

Answer 1

Another correct construction, which we can use in this situation:

UPDATE T1, T2,
[INNER JOIN | LEFT JOIN] T1 ON T1.C1 = T2. C1
SET T1.C2 = T2.C2, 
    T2.C3 = expr
WHERE condition

The above example is take from: MySQL UPDATE JOIN.

Reaching for the MySQL 8.0 Reference Manual we will find such a description of multiple-table UPDATE syntax:

UPDATE [LOW_PRIORITY] [IGNORE] table_references
SET assignment_list
[WHERE where_condition]

The table_references clause lists the tables involved in the join.

So multiple-table MySQL's syntax doesn't support FROM, ORDER BY or LIMIT clauses as opposed to single-table syntax.
