Flyway upgrade from 3.2.1 to 4.0 fails with Oracle error ORA-00955: name is already used by an existing object

See original GitHub issue

What version of Flyway are you using?

3.2.1

What database are you using (type & version)?

Oracle 11g (11.2.0.1.0)

What operating system are you using?

Windows 7 SP1

What did you do?

After replacing flyway-core-3.2.1.jar with flyway-core-4.0.jar and redeploying my application, Flyway attempts to upgrade the “schema_version” table, but fails with the following Oracle error:

ORA-00955: name is already used by an existing object

At issue is the fact that the upgrade script removes the old PK constraint using the following statement:

ALTER TABLE "schema_version" DROP CONSTRAINT "schema_version_pk";

While this does remove the PK constraint, it does not always remove the implicit index created with the same name. As a result, the upgrade script fails when attempting to create a new constraint with the name “schema_version_pk”. Replacing the above statement with the one below in the Oracle upgrade script resolves this issue:

ALTER TABLE "schema_version" DROP PRIMARY KEY DROP INDEX;

What did you expect to see?

I expected to see the flyway “schema_version” table successfully upgraded.

What did you see instead?
