Aug 23, 2013 Oracle Java JDBC: Get Primary Key of Inserted record. By Viral Patel August 23, 2013. It gives us the result set of all auto generated key values. In our case as we have only one auto generated value (for studentid column) we get only single record in this result set. How to set custom Favicon in Spring Boot. In the general case, the keys are returned as a List containing one Map for each row of keys. Most applications only use on key per row and process only one row at a time in an insert statement. In these cases, just call getKey to retrieve the key. The returned value is a Number here, which is the usual type for auto-generated keys.
This post provides code example that gets the value of the newly inserted record in database using JDBC.
Some database operations, especially those involving parent-child relationships (one-to-many), you may want to insert a record into the parent table first, then into the child table. But the records in the child table must have a foreign key that refers to the parent table’s primary key. In such case, you need a technique that retrieves the value of the primary key of the last record inserted (usually auto-incremented by the database engine). JDBC provides such mechanism but implementation is slightly different for different database systems.

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.

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.
