using your data, assuming 'tom', 'ron', 'chris' and 'bert' are table names.

DELETE tom.*, ron.*, chris.*, bert.*
FROM tom, ron, chris, bert
WHERE id = '$value';

In syntax "markup" anything in angle brackets, < >, is a required field, anything inside brackets [ ], is optional. So DELETE FROM <table> means that you must have something where it says <table>, ie., DELETE FROM someTable .

That said the query format is

DELETE FROM <table > [, table [...]] [WHERE <col> = <value> [LIMIT <offset>[,<number>]

Meaning that you can do DELETE FROM someTable, someSecondTable WHERE row = 3 LIMIT 0,2 Which would delete everything from someTable and someSecondTable where row is equal to 3. Or I could simply do, DELETE FROM someTable WHERE row = 3
