Jdbc Batch Insert Get Generated Keys Spring
Mar 18, 2015 Introduction JDBC has long been offering support for DML statement batching. By default, all statements are sent one after the other, each one in a separate network round-trip. Batching allows us to send multiple statements in one-shot, saving unnecessary socket stream flushing. Hibernate hides the database statements behind a transactional write-behind abstraction layer. An intermediate layer. Mar 01, 2012 Let’s see how we can perform batch insert in Java using JDBC APIs. Although you might already knew this, I will try to explain the basic to a bit complex scenarios. In this note, we will see how we can use JDBC APIs like Statement and PreparedStatement to insert data in any database in batches. Now, let's implement a method which will use JDBCTemplate to insert the new record and return the auto-generated id. Therefore, we'll use the JDBCTemplate update method which supports the retrieval of primary keys generated by the database. JDBI, a Nice Spring JDBC Alternative. (for example it not being able to handle getting the generated keys for a batch insert in an easy way). I’m always interested in giving other solutions a.

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.

Because SQL Server doesn't support pseudo columns for identifiers, updates that have to use the auto-generated key feature must operate against a table that contains an IDENTITY column. SQL Server allows only a single IDENTITY column per table. The result set that is returned by getGeneratedKeys method of the SQLServerStatement class will have only one column, with the returned column name of GENERATED_KEYS. If generated keys are requested on a table that has no IDENTITY column, the JDBC driver will return a null result set.
As an example, create the following table in the sample database:

In the following example, an open connection to the sample database is passed in to the function, an SQL statement is constructed that will add data to the table, and then the statement is run and the IDENTITY column value is displayed.
