Failed to execute SQL: DROP INDEX IF EXISTS ofMucConvLog_msg_id;

Hi experts,

I was upgrading the embedded Openfire in our product from 3.9.3 to 4.3.1 (DB: MS SQLServer) and found the upgrade stopped at db version 25.

The error log:

2019.02.28 13:59:09 org.jivesoftware.database.SchemaManager - SchemaManager: Failed to execute SQL:

DROP INDEX IF EXISTS ofMucConvLog_msg_id;

2019.02.28 13:59:09 org.jivesoftware.database.SchemaManager - Must specify the table name and index name for the DROP INDEX statement.

java.sql.SQLException: Must specify the table name and index name for the DROP INDEX statement.

at net.sourceforge.jtds.jdbc.SQLDiagnostic.addDiagnostic(SQLDiagnostic.java:372) ~[jtds-1.3.1.jar:1.3.1]

The SQL should be changed to:
DROP INDEX IF EXISTS ofMucConvLog_msg_id ON ofMucConversationLog;

I’m not sure if the upgrade of the official Openfire will also fail in this case, or if there are some other logic to prevent it from happening.

Thanks!

Thank you for the bug report; even more appreciated it has the fix! I’ve raised https://issues.igniterealtime.org/browse/OF-1698 to track this.

Greg’s fix has been merged. The new update script will be part of 4.3.3 as well as 4.4.0. I’d appreciate if someone could test the fix using a nightly build.

The solution had been verified on SQL server before I posted this topic.

BTW, Oracle has no such IF EXISTS option. Need use plsql block to achieve this:
[
DECLARE
index_count INTEGER;
BEGIN
SELECT COUNT(*) INTO index_count
FROM USER_INDEXES
WHERE INDEX_NAME IN (‘ofMucConvLog_msg_id’, UPPER(‘ofMucConvLog_msg_id’));
IF index_count > 0 THEN
EXECUTE IMMEDIATE ‘DROP INDEX ofMucConvLog_msg_id’;
END IF;
END;
]

Note that by default, all text tokens are converted to uppercase and then indexed in Oracle, so should also compare upper cased index name.
