I have the following SQL query that (appears to have some kind of whitespace at the end)is returning data in my XML output and I am trying to remove this upfront in the SQL from being shown in the XML output:

Is there a beautiful simple solution how to check if two tables have one-to-many relationship between each other using only their names as parameters? I’ve seen solutions with joining tables on specific fields but can I do it without knowing what foreign keys my tables have? (Or possibly get it from system tables like user_tab_columns etc.)

I have a table where each record represents a transaction by a user. I need to find out if any user has inserted 1000 or more records within a 1 hour time window on a specific date. For example, if a user inserts more than 1000 records between 12:15 PM to 01:15 PM, I want to capture that information.
