So the function can be use for INSERT, UPDATE and DELETE operations also any operation that doesn’t need a return result sets. This function accepts a parameter as sql command and send to execute on MySQL Server. Note: You can use ExecuteNonQuery to perform any type of database operation, however any result sets returned will not be available. For all other types of statements, the return value is -1. For INSERT, UPDATE and DELETE statements, the return value is the number of rows affected by the command. So I use ExecuteNonQuery() Method from MySqlCommand Class. When I perform these operations to database, there is no need to get records from the database. The result of the query shows the first and second columns in the output window.Ĭoding on INSERT, UPDATE and DELETE SQL operations are identical except only sql command that is executed.
