6.4 Retrieving AUTO_INCREMENT Column Values through JDBC

Before version 3.0 of the JDBC API, there was no standard way of retrieving key values from databases that supported auto increment or identity columns. With older JDBC drivers for MySQL, you could always use a MySQL-specific method on the Statement interface, or issue the query SELECT LAST_INSERT_ID() after issuing an INSERT to a table that had an AUTO_INCREMENT key. Using the MySQL-specific method call isn't portable, and issuing a SELECT to get the AUTO_INCREMENT key's value requires another round-trip to the database, which isn't as efficient as possible. The following code snippets demonstrate the three different ways to retrieve AUTO_INCREMENT values. First, we demonstrate the use of the new JDBC 3.0 method getGeneratedKeys() which is now the preferred method to use if you need to retrieve AUTO_INCREMENT keys and have access to JDBC 3.0. The second example shows how you can retrieve the same value using a standard SELECT LAST_INSERT_ID() query. The final example shows how updatable result sets can retrieve the AUTO_INCREMENT value when using the insertRow() method.

In this article, we looked at the JDBC abstraction in the Spring Framework, covering the various capabilities provided by Spring JDBC with practical examples. Also, we looked into how we can quickly get started with Spring JDBC using a Spring Boot JDBC starter. The source code for the examples is available over on GitHub. Spring JDBC provides extraction over plain JDBC by providing various templates such jdbctemplate, named parameter template and better exception handling compared to plain JDBC.It makes mapping easier between a relational database and java beans with the help of different mapper classes. Also, there are cleaner ways to execute stored proc. Following are some of the tutorials on spring jdbc. This example shows how to retrieve auto generated primary key by the database (via an insert statement). Following method of JdbcTemplate takes KeyHolder argument which will contain the generated key on the successful insert execution.

Retrieving auto-generated keys using SPRING JDBC. By Yashwant Chavan, Views 22771, Last updated on 14-Feb-2019. Welcome to another spring jdbctemplate tutorial. In our todays article we are going to learn how to retrieve the auto generate key using spring JDBC template. The Microsoft JDBC Driver for SQL Server supports the optional JDBC 3.0 APIs to retrieve automatically generated row identifiers. The main value of this feature is to provide a way to make IDENTITY values available to an application that is updating a database table without a requiring a query and a second round-trip to the server. May 28, 2017 In this video you will learn How to get primary key value (auto-generated keys) from inserted queries in JDBC using a demo project. Below is the GitHub link to download source code. Spring provides KeyHolder which helps to get auto generated key. KeyHolder is supported by JDBC 3.0.

The private key is generated simultaneously with the CSR (certificate signing request), containing the domain name, public key and additional contact information. The CSR is to be sent to the certificate authority for validation and signing immediately after the certificate activation in. Jul 09, 2019  The private key gets generated along with your Certificate Signing Request (CSR). The CSR is submitted to the certificate authority right after you activate your certificate, while the private key must be kept safe and secret on your server or device. Later on, this key is used for installation of your certificate.

At times, it can be tricky to use the SELECT LAST_INSERT_ID() query, as that function's value is scoped to a connection. So, if some other query happens on the same connection, the value is overwritten. On the other hand, the getGeneratedKeys() method is scoped by the Statement instance, so it can be used even if other queries happen on the same connection, but not on the same Statement instance.
