Extending MERGE in Oracle SQL: Strategies for Handling Unmatched Rows with Soft Deletes
This article explores how to elegantly handle rows that are not matched in the source table when using the MERGE statement for data synchronization in Oracle databases, particularly in scenarios requiring soft deletes instead of physical deletions. Through a detailed case study involving syncing a table from a main database to a report database and setting an IsDeleted flag when records are deleted in the main database, the article presents the best practice of using a separate UPDATE statement. This method identifies records in the report database that do not exist in the main database via a NOT EXISTS subquery and updates their deletion flag, overcoming the limitations of the MERGE statement. Alternative approaches, such as extending source data with UNION ALL, are briefly discussed but noted for their complexity and potential performance issues. The article concludes by highlighting the advantages of combining MERGE and UPDATE statements in data synchronization tasks, emphasizing code readability and maintainability.
