When asking or editing a question, is it better (from SEO or user perspective) for the title of the question to be an actual question? Do we even care? If the preference is for questions, is there any preference for how the questions starts ("How do I", "What is", etc)?
For example, given Get list of all tables in Oracle?, would any of these titles be preferable:
- SQL Query to display all tables in an Oracle database (current title)
- What is the SQL query to display all tables in an Oracle database?
- Is there an SQL query to display all tables in an Oracle database?
- How do I display all tables in an Oracle database with SQL?
- Can I display all tables in an Oracle database with SQL?
- something else?
Obviously, we want the format that will make it easiest to find duplicate questions, so that fewer duplicates are asked. But I don't know which format that is.
