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()7 days to die steam key generator. 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.
Statement.executeUpdate(sql-statement, Statement.RETURNGENERATEDKEYS); The following forms are valid only if the data source supports SELECT FROM INSERT statements. Sql-statement can be a single-row INSERT statement or a multiple-row INSERT statement. With the first form, you specify the names of the columns for which you want automatically.
Next, you supply values for placeholders by calling setYYY() method of the PreparedStatement object.

Problem with Statement.RETURNGENERATEDKEYS ra.416892.us Mar 15, 2004 4:05 PM Dear Colleagues, I am using Oracle 9i Enterprise Edition Release 9.2.0.1.0 with Java 1.4.101 on Red Hat Linux 8.0 and I am observing the following problem. MySQL Connector/J 5.1 Developer Guide / JDBC Concepts / Retrieving AUTOINCREMENT Column Values through JDBC 6.4 Retrieving AUTOINCREMENT Column Values through JDBC Before version 3.0 of the JDBC API, there was no standard way of retrieving key values from databases that supported auto increment or identity columns.
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.
