Pergunta
My innodb table has the following structure: 4 columns (CountryID, Year, %Change, Source)
, with the 2 columns (CountryID, Year)
as the primary key. How do I delete multiple rows other than using a for-loop to delete each row?
I'm looking for something similar to
DELETE FROM CPI
WHERE CountryID AND Year IN (('AD', 2010), ('AF', 2009), ('AG', 1992))
Solução
The answer in Oracle is:
delete from cpi
where (countryid, year) in (('AD', 2010), ('AF', 2009), ('AG', 1992))
It's fairly standard SQL syntax and I think MySQL is the same.
