Preparedstatement Conn Sql Statement.return_generated_keys

An interface for a precompiled SQL Statement. An SQL Statement is put into a PreparedStatement and is precompiled so that it can be executed efficiently multiple times. Setter methods are supplied in the PreparedStatement interface for the setting of IN parameters for the statement.

The following are Jave code examples for showing how to use setInt of the java.sql.PreparedStatement class. You can vote up the examples you like.
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.

The PreparedStatement interface is a subinterface of Statement. It is used to execute parameterized query.

Let's see the example of parameterized query:

Java Sql Preparedstatement

As you can see, we are passing parameter (?) for the values. Its value will be set by calling the setter methods of PreparedStatement.

Why use PreparedStatement?

Improves performance: The performance of the application will be faster if you use PreparedStatement interface because query is compiled only once.

How to get the instance of PreparedStatement?

The prepareStatement() method of Connection interface is used to return the object of PreparedStatement. Syntax: Crack playon license key generator.

Methods of PreparedStatement interface

The important methods of PreparedStatement interface are given below:

Method	Description
public void setInt(int paramIndex, int value)	sets the integer value to the given parameter index.
public void setString(int paramIndex, String value)	sets the String value to the given parameter index.
public void setFloat(int paramIndex, float value)	sets the float value to the given parameter index.
public void setDouble(int paramIndex, double value)	sets the double value to the given parameter index.
public int executeUpdate()	executes the query. It is used for create, drop, insert, update, delete etc.
public ResultSet executeQuery()	executes the select query. It returns an instance of ResultSet.

Example of PreparedStatement interface that inserts the record
