Get the new record key ID from MySQL insert query?
We can get new record key with the help of LAST_INSERT_ID() function from MySQL. First, we will create a table and for inserting record, we will use LAST_INSERT_ID().
Let us create a table with the help of create command.
The query is as follows −
mysql> create table LastInsertRecordIdDemo -> ( -> id int auto_increment, -> value varchar(100), -> primary key(id) -> ); Query OK, 0 rows affected (0.52 sec)
After creating a table, we will insert records and set it using LAST_INSERT_ID() function.
mysql> insert into LastInsertRecordIdDemo values(1,'Low'); Query OK, 1 row affected (0.10 sec) mysql> insert into LastInsertRecordIdDemo values(LAST_INSERT_ID(),'High'); Query OK, 1 row affected (0.11 sec)
Now we can display all the records with the help of select statement.
The query is as follows −
mysql> select *from LastInsertRecordIdDemo;
The following is the output.
+----+-------+ | id | value | +----+-------+ | 1 | Low | | 2 | High | +----+-------+ 2 rows in set (0.00 sec)
Now to insert records, we need to add 1 in the function LAST_INSERT_ID (). The query is as follows −
mysql> insert into LastInsertRecordIdDemo values(LAST_INSERT_ID()+1,'Medium'); Query OK, 1 row affected (0.08 sec)
Now we can display all records with the help of select statement.
mysql> select *From LastInsertRecordIdDemo;
The following is the output.
+----+--------+ | id | value | +----+--------+ | 1 | Low | | 2 | High | | 3 | Medium | +----+--------+ 3 rows in set (0.00 sec)
