rowsUpdated

rowsUpdated refers to a property or variable commonly found in database interactions and programming contexts. Its primary function is to indicate the number of rows that have been successfully modified, inserted, or deleted by a database operation. When a query such as an UPDATE, INSERT, or DELETE statement is executed, the database system typically returns a value representing the count of affected rows. This count is often stored in a variable or returned as part of the result set, and this value is what is commonly referred to as rowsUpdated.

Developers utilize rowsUpdated to verify the outcome of database operations. For instance, after attempting to update a record, checking rowsUpdated can confirm whether the record was actually modified. A value of zero might indicate that no matching records were found, or that the update operation did not result in any changes. Conversely, a positive integer signifies the number of records that were altered. This feedback mechanism is crucial for error handling, debugging, and ensuring the integrity of data within an application. In various programming languages and database connectors, this value is accessible through specific methods or properties associated with the executed query or statement object.
