Here we will use mysql_insert_id() function to get the id generated after the insert command . If you insert multiple rows using a single INSERT statement, LAST_INSERT_ID() returns the value automatically generated for the first inserted row only, see Practice #4 . This enables multiple-row inserts to be reproduced correctly on other servers in a replication setup. En versiones modernas MySQL utiliza una tabla de estado para generar los nuevos ID, por lo que no hay un impacto de "lentitud" cuando hay muchos registros. in that textfield i want to show the next auto_increment id from mysql database.

For example when we issue a student ID number, where student ID is an auto increment field we can generate IDs with values 100001 from the first record. Copy and paste the following query to create the Table (search), Column names (Id, Name), and then insert dummy data. They will all show the same next ID, but after they submit a different ID will actually be used. Creating a table, with “id” as auto-increment. MDB2 can emulate this behaviour for RDBMS that do not support autoincrement at table creation time when using the createTable() method. Decrementing null values has no effect too, but incrementing them results in 1.
