I am not deeply acquainted with Oracle Sql Queries, therefore I face a problem on deleting some rows from a table which must fulfill a constraint which includes fields of another (joining) table. In other words I want to write a query to delete rows including JOIN.
In my case I have a table ProductFilters and another table Products joined on fields ProductFilters.productID = Products.ID. I want to delete the rows from ProductFilters having an ID higher or equal to 200 and the product they refer has the name 'Mark' (name is a field in Product).
I would like to be informed initially if JOIN is acceptable in a Delete Query in Oracle. If not how should I modify this Query in order to make it work, since on that form I receive an error:
DELETE From PRODUCTFILTERS pf
where pf.id>=200
And pf.rowid in
(
Select rowid from PRODUCTFILTERS
inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID
And PRODUCTS.NAME= 'Mark'
);
Based on the answer I linked to in my comment above, this should work:
delete from
(
select pf.* From PRODUCTFILTERS pf
where pf.id>=200
And pf.rowid in
(
Select rowid from PRODUCTFILTERS
inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID
And PRODUCTS.NAME= 'Mark'
)
);
or
delete from PRODUCTFILTERS where rowid in
(
select pf.rowid From PRODUCTFILTERS pf
where pf.id>=200
And pf.rowid in
(
Select PRODUCTFILTERS.rowid from PRODUCTFILTERS
inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID
And PRODUCTS.NAME= 'Mark'
)
);
