The INSERT statement is generated based on the configuration of SimpleJdbcInsert and all we need is to provide the Table name. To allow the database to generate the primary key. We looked into how we can quickly get started with Spring JDBC using a Spring Boot JDBC starter. 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. This method takes an instance of the PrepareStatementCreator interface as the first argument and the other argument is the. Following example will demonstrate how to make a batch update using Spring JDBC. We'll update the available records in Student table in a single batch operation. To understand the above-mentioned concepts related to Spring JDBC, let us write an example which will update a batch operation. Microsoft office student 2010 product key generator.

Following example will demonstrate how to make a batch update using Spring JDBC. We'll update the available records in Student table in a single batch operation.
Syntax
Where,
- SQL − Update query to update student's age.
- jdbcTemplateObject − StudentJDBCTemplate object to update student object in database.
- BatchPreparedStatementSetter − Batch executor, set values in PerparedStatement per item identified by list of objects student and index i. getBatchSize() returns the size of the batch.
- updateCounts − Int array containing updated row count per update query.
To understand the above-mentioned concepts related to Spring JDBC, let us write an example which will update a batch operation. To write our example, let us have a working Eclipse IDE in place and use the following steps to create a Spring application.
Step | Description |
---|---|
1 | Update the project Student created under chapter Spring JDBC - First Application. |
2 | Update the bean configuration and run the application as explained below. |

Once you are done creating the source and bean configuration files, let us run the application. If everything is fine with your application, it will print the following message.
In this tutorial, you will learn how to use PreparedStatement object to insert data into MySQL table.
In the previous tutorial, we have shown you how to use the PreparedStatement object to update data. When you call the
executeUpdate()
method, you get the number of rows affected. When you insert a record into a table, you may want to get the inserted ID back to the program for further processing. Let’s see how we can do it.First, as always, you open a new connection to MySQL. You can utilized the utility class
MySQLJDBCUtil
that we developed in the previous tutorial.Then, you construct an
INSERT
statement with placeholders and create a new PreparedStatement
object by calling the prepareStatement()
method of the Connection
object. You pass the INSERT statement as the first argument and an integer with value Statement.RETURN_GENERATED_KEYS
as the the second argument to the method. The second argument instructs JDBC to give the inserted ID back.Jdbc Batch Insert Get Generated Keys Spring Texas
Next, you supply values for placeholders by calling
setYYY()
method of the PreparedStatement
object.After that, you call the
executeUpdate()
method to execute the INSERT
statement. This method returns the number of rows affected. We check the return value to see if the record has been inserted successfully.Finally, to get the inserted id, you call the
getGeneratedKeys()
method of the PreparedStatement
object. The method returns a ResultSet
. You just need to get data out of this ResultSet
as follows:The following is the complete example of inserting data into the
candidates
table and get the inserted ID back.Let’s run the program.
It shows that you have successfully inserted a new candidate into the
candidates
table with id 134.In this tutorial, we have shown you how to use PreparedStatement object to insert a new record into a MySQL table and get the inserted ID back for further processing.
