This can be any SQL statement, such as INSERT, UPDATE, DELETE, SELECT&#8230;<\/p><p>For SQL ROWCOUNT to function correctly, it is imperative that both queries (ROWCOUNT and the statement affecting the rows) are in the same execution. If they are executed separately, the value returned will be 1, which does not correspond to the number of rows affected by the previously executed statement.<\/p><p>The aim of @@ROWCOUNT is to avoid infinite loops when a database is analyzed in a loop. When all rows have been processed, SQL ROWCOUNT automatically stops the analysis process.<\/p><p>In addition to processing data in a loop, this query can also be used to check the number of rows allocated in a statement.
