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.

• The method Statement.getGeneratedKeys, which can be called to retrieve the value of such a key, returns a ResultSet object with a column for each automatically generated key. A flag indicating that any auto generated columns should be returned is passed to the methods execute, executeUpdate or prepareStatement when the statement is executed.
• JDBC's auto-generated keys feature provides a way to retrieve values from columns that are part of an index or have a default value assigned. Derby supports the auto-increment feature, which allows users to create columns in tables for which the database system automatically assigns increasing integer values. Users can call the method Statement.getGeneratedKeys to retrieve the value of such a.

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.

How to get primary key value (auto-generated keys) from inserted queries using JDBC? Description: When we are inserting a record into the database table and the primary key is an auto-increment or auto-generated key, then the insert query will generate it dynamically. Using the JdbcTemplate. 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. MySQL and Java « Previous Message. Openssl generate pkcs8 rsa key pair. 1.4 Notice that the word key is plural, meaning if a statement causes the creating of more than one key then the ResultSet object should return all keys. Re: retrieving auto-generated keys on bulk insert: Christopher Taylor: 8 Jan. 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 GENERATEDKEYS. If generated keys are requested on a table that has no IDENTITY column, the JDBC driver will return a null result set. Get a MySQL Connection from the Driver Manager: 20.34.2.

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.
