Steps to Reproduce

1. Create a database in Microsoft SQL Server with the Confluence name
2. Install Confluence 6.13
3. Connect Confluence to the Microsoft SQL Server database using the connection string url as confluence (instead of Confluence with an uppercase letter C).
4. Upgrade Confluence 6.13 to 6.15.x

Expected Results

• Confluence updates successfully

Actual Results

• Upgrade fails with:

  Caused by: java.sql.SQLException: The database name component of the object qualifier must be the name of the current database.
  

Workaround

1. Get the name of your database by running the following query:

   SELECT name, database_id, create_date FROM sys.databases;  
   

2. Compare it with the name of the database located in your <confluence_home>/confluence.cfg.xml file
3. Update the database name so it matches the exact name of the database from the SQL statement.
4. Restart Confluence
