Multiple tables records deletion. How?

Hi,

I’ve 4 tables from which i need to delete rows. Below are the tables:

Table s
Table a
Table v
Table p

  1. Column a_sid of table “a” references column s_id of table “s” where s_id is primary key so as a_sid.
  2. Column v_sid of table “v” references column s_id of table “s”
  3. Column p_sid of table “p” references column s_id of table “s”

I need to delete all rows of 4 tables where a_type of “a” table = “AC”

Please help.
Thanks,
Ramki

From the manual:


DELETE t1, t2, t3 FROM t1 INNER JOIN t2 INNER JOIN t3
WHERE t1.id=t2.id 
AND   t1.id=t3.id

You just need to change it a bit and adapt it to your situation

Thanks guido. It worked :slight_smile:

eeeeeeeeewwwwwwwwwwwwww!!! :mad: :mad: :mad:

i didn’t believe it until looked it up, and that is indeed what it says

please, let’s not ever show anyone that particular example again

instead, let’s show them this –

DELETE t1, t2, t3 
  FROM t1 
INNER 
  JOIN t2 
    [COLOR="Blue"][B]ON[/B][/COLOR] t2.id = t1.id
INNER 
  JOIN t3
    [COLOR="Blue"][B]ON[/B][/COLOR] t3.id = t1.id

thank you

You know, I had some doubts, so I read it twice and looked at the whole page in search of some ‘ON’ clause, but there wasn’t, so I assumed in the case of multiple table deletes the MySQL syntax was different…
I’m glad you confirm my doubts :smiley:
