The process for obtaining distinct rows from several interconnected tables that have foreign keys while also including a key to an independent table involves the use of SQL JOIN statements. The following steps outline the process:
Identify the tables involved in the query, including any foreign keys and the independent table.
Use the appropriate JOIN statement to connect the tables. This will depend on the relationship between the tables and the type of JOIN required.
Specify the columns that need to be included in the result set. This will include the foreign keys and any additional columns from the independent table.
Use the DISTINCT keyword to ensure that only unique rows are returned.
Specify any additional filtering criteria, such as WHERE clauses, to further refine the results.
Execute the query and review the results to ensure that the desired output has been achieved.
