3. Create the PackageBases table:
----
CREATE TABLE PackageBases (
ID INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
Name VARCHAR(64) NOT NULL,
CategoryID TINYINT UNSIGNED NOT NULL DEFAULT 1,
NumVotes INTEGER UNSIGNED NOT NULL DEFAULT 0,
OutOfDateTS BIGINT UNSIGNED NULL DEFAULT NULL,
SubmittedTS BIGINT UNSIGNED NOT NULL,
ModifiedTS BIGINT UNSIGNED NOT NULL,
SubmitterUID INTEGER UNSIGNED NULL DEFAULT NULL,
MaintainerUID INTEGER UNSIGNED NULL DEFAULT NULL,
PRIMARY KEY (ID),
UNIQUE (Name),
INDEX (CategoryID),
INDEX (NumVotes),
INDEX (SubmitterUID),
INDEX (MaintainerUID),
FOREIGN KEY (CategoryID) REFERENCES PackageCategories(ID) ON DELETE NO ACTION,
-- deleting a user will cause packages to be orphaned, not deleted
FOREIGN KEY (SubmitterUID) REFERENCES Users(ID) ON DELETE SET NULL,
FOREIGN KEY (MaintainerUID) REFERENCES Users(ID) ON DELETE SET NULL
) ENGINE = InnoDB;
----
4. Migrate data from Packages to PackageBases:
----
INSERT INTO PackageBases SELECT ID, Name, CategoryID, NumVotes, OutOfDateTS,
SubmittedTS, ModifiedTS, SubmitterUID, MaintainerUID FROM Packages;
----
5. Delete unneeded foreign keys from Packages:
First, drop the foreign keys on CategoryID, SubmitterUID and MaintainerUID. The
following queries should work in most cases:
----
ALTER TABLE Packages
DROP FOREIGN KEY Packages_ibfk_1,
DROP FOREIGN KEY Packages_ibfk_2,
DROP FOREIGN KEY Packages_ibfk_3;
----
You can use `SHOW CREATE TABLE Packages;` to check whether you should use
different names for your setup.
6. Delete unneeded fields from Packages:
----
ALTER TABLE Packages
DROP COLUMN CategoryID,
DROP COLUMN NumVotes,
DROP COLUMN OutOfDateTS,
DROP COLUMN SubmittedTS,
DROP COLUMN ModifiedTS,
DROP COLUMN SubmitterUID,
DROP COLUMN MaintainerUID;
----
7. Add package base references to the Packages table:
----
ALTER TABLE Packages
ADD COLUMN PackageBaseID INTEGER UNSIGNED NULL,
ADD FOREIGN KEY (PackageBaseID) REFERENCES PackageBases(ID) ON DELETE CASCADE;
UPDATE Packages SET PackageBaseID = ID;
ALTER TABLE Packages MODIFY PackageBaseID INTEGER UNSIGNED NOT NULL;
----
8. Delete foreign keys from PackageVotes, PackageComments and CommentNotify:
----
ALTER TABLE PackageVotes
DROP FOREIGN KEY PackageVotes_ibfk_1,
DROP FOREIGN KEY PackageVotes_ibfk_2;
ALTER TABLE PackageComments
DROP FOREIGN KEY PackageComments_ibfk_3;
ALTER TABLE CommentNotify
DROP FOREIGN KEY CommentNotify_ibfk_1,
DROP FOREIGN KEY CommentNotify_ibfk_2;
----
We highly recommend to use `SHOW CREATE TABLE PackageVotes;` etc. to check
whether you should use different names for your setup.
9. Delete indexes from PackageVotes and CommentNotify:
----
ALTER TABLE PackageVotes DROP INDEX VoteUsersIDPackageID;
ALTER TABLE CommentNotify DROP INDEX NotifyUserIDPkgID;
----
10. Migrate PackageVotes, PackageComments and CommentNotify to refer to package
bases:
----
ALTER TABLE PackageVotes ADD COLUMN PackageBaseID INTEGER UNSIGNED NOT NULL;
UPDATE PackageVotes SET PackageBaseID = PackageID;
ALTER TABLE PackageVotes DROP COLUMN PackageID;
ALTER TABLE PackageComments ADD COLUMN PackageBaseID INTEGER UNSIGNED NOT NULL;
UPDATE PackageComments SET PackageBaseID = PackageID;
ALTER TABLE PackageComments DROP COLUMN PackageID;
ALTER TABLE CommentNotify ADD COLUMN PackageBaseID INTEGER UNSIGNED NOT NULL;
UPDATE CommentNotify SET PackageBaseID = PkgID;
ALTER TABLE CommentNotify DROP COLUMN PkgID;
----
11. Recreate missing foreign keys and indexes:
----
ALTER TABLE PackageVotes
ADD FOREIGN KEY (UsersID) REFERENCES Users(ID) ON DELETE CASCADE,
ADD FOREIGN KEY (PackageBaseID) REFERENCES PackageBases(ID) ON DELETE CASCADE;
ALTER TABLE PackageComments
ADD FOREIGN KEY (PackageBaseID) REFERENCES PackageBases(ID) ON DELETE CASCADE;
ALTER TABLE CommentNotify
ADD FOREIGN KEY (PackageBaseID) REFERENCES PackageBases(ID) ON DELETE CASCADE,
ADD FOREIGN KEY (UserID) REFERENCES Users(ID) ON DELETE CASCADE;
CREATE UNIQUE INDEX VoteUsersIDPackageID ON PackageVotes (UsersID, PackageBaseID);
CREATE UNIQUE INDEX NotifyUserIDPkgID ON CommentNotify (UserID, PackageBaseID);
----
