Code language: SQL (Structured Query Language) (sql) When you insert a row into the table without specifying a value for the id column, MySQL automatically generates a sequential unique integer for the id column.The LAST_INSERT_ID() function returns the first automatically generated integer ( BIGINT UNSIGNED) successfully inserted for an AUTO_INCREMENT … Content reproduced on this site is the property of its respective owners, and this content is not reviewed in advance by MariaDB. the ON DUPLICATE KEY UPDATE clause is used and example, inserting the string '1999.0e-2' given INSERT statement do not match This MySQL tutorial explains how to use the RETURN statement in MySQL with syntax and examples. function when connecting to mysqld, the function.

Use mysql_num_rows() to find out how many rows were returned for a SELECT statement or mysql_affected_rows() to find out how many rows were affected by a DELETE, INSERT, REPLACE, or UPDATE statement. mysql_affected_rows().

In this tutorial, you will learn how to use PreparedStatement object to insert data into MySQL table and get inserted ID back. explicitly to its default value. In Oracle, when you execute an INSERT statement, you can use a trigger to assign some values, for example, to generate ID using a sequence.
