Spring Jdbc Insert Sql Get Generated Key
To get the generated key from a MySQL database table, just use the MySQL LASTINSERTID function, calling it as shown below, immediately after performing your INSERT command (and very importantly, also using the same connection): SELECT LASTINSERTID; Here's a blurb from this MySQL page. LASTINSERTID (with no argument) returns the first automatically generated value that was set for.
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. 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.

JDBC 3.0 introduced to get auto generated keys using getGeneratedKeys() method, It return the ResultSet object with the help of next() method of result set we retrieve the auto generated key value.

Mysql Auto generated Key Value
Sometimes we need to retrive auto generated key for the inserted statement. Refer the below example to get the Auto generated emp_id column value using JDBC.Get the Statement from Jdbc Connection. Statement object use to sending SQL statements to the database.
Executes the below program, Which insert the record in the trn_employee table. After record insertion it return the auto generated primary key value
getGeneratedKeys() method returns the ResultSet object and from that we retrive the primary key number.

Note : On Every execution of program , it generates next auto incremented number.

-->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.
