[Bug]: Upgrade to stable32 with oracle database fails

[grnd-alt]

Upgrading to any stable32 version of 32.0.4 or higher fails when using an oracle database.
this line tries truncating the table oc_mounts.The oracle driver seems to somehow make that table name uppercase so when updating the table OC_MOUNTS does not exist.
removing that line, truncating the table manually and doing the upgrade resolves the issue.

I think the root cause is the connection->truncateTable call but I don't know what the appropriate call would be to use.

steps to reproduce

• setup 32.0.1
• update to 32.0.4
