Question

This code doesn’t work on mysql:

update member
set member.xy = memba.surba
from memba
where member.id =memba.id

The code below0 works:

update member inner join memba on member.id =memba.id
set member.xy = memba.surba

Could you please explain what’s wrong with the first code?

Answer 1

Multiple-table syntax:

UPDATE [LOW_PRIORITY] [IGNORE] table_references
    SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
    [WHERE where_condition]

It would seem that you have a FROM clause that is not part of the update statement in MySQL.
