If you insert records into a table which contains auto-incremented column, using a Statement or, PreparedStatement objects.
You can retrieve the values of that particular column, generated by them object using the getGeneratedKeys() method.
Example
Let us create a table with name sales in MySQL database, with one of the columns as auto-incremented, using CREATE statement as shown below −
Retrieving auto-generated values (PreparedStatement object)
Following JDBC program inserts 3 records into the Sales table (created above) using PreparedStatement, retrieves and displays the auto-incremented values generated by it.
Example
Output
Retrieving auto-generated values (Statement object)
Borderlands 2 shift key generator. Following JDBC program inserts 3 records into the Sales table (created above) using Statement, retrieves and displays the auto-incremented values generated by it.

Here is a small write-up which should help those who still write plain Java JDBC code. I know we have some wonderful persistence frameworks like Hibernate that make ones life comfortable but the reality is we still have to deal with plain old JDBC apis. If you are poor chap like me, below code should make your life easy.
Problem statement:
I just inserted a record in Oracle database using Java JDBC. The primary key column was auto populated by a sequence value. How should I get the last inserted records auto generated primary key?
Solution:
The solution should be getGeneratedKeys(). This method was added in JDBC 3.0 and it should be used to get last auto generated key value.
Jdbc Batch Insert
See code snippet below:
The above code should give us auto generated primary key value. The one thing to note here is method prepareStatement(). We passed two arguments first the insert query string and second an array of column name. The column name should be the primary key column name of table where you inserting the record.
Check below source code to see complete solution.

We have a database table called
STUDENTS
. We also have an oracle sequence called STUDENT_SEQ
that we uses to generate primary key for STUDENTS table. Unreal tournament cd key generator.Jdbc Batch Query
In Java, we use plain JDBC calls to insert a record in
STUDENTS
Openssl generate ecc key with password. table. We uses sequence STUDENT_SEQ
to generate primary key. Once the record is inserted, we want the last inserted primary value.Spring Jdbc Batch Insert
The above code is filled with comments and is pretty self explanatory. Finally we have last inserted value in
studentId
variable.Jdbc Batch Insert Generated Keys Mysql File
The
getGeneratedKeys()
method is key here. It gives us the result set of all auto generated key values. In our case as we have only one auto generated value (for student_id column) we get only single record in this result set.
