Prerequisites

1. Downloading, installing and configuring the database

See the installation and configuration note for your database.

2. Create table and insert data as:

Create table employee(empName varchar(20), id int PRIMARY KEY)

insert into employee values (‘name1’,1)

insert into employee values (‘name2’,2)

We can define columns in databases which will auto increment its values whenever we add a new row. Different databases have different ways to do so and even call them differently like auto increment, identity column etc. We will discuss the auto increment for some databases here. Please feel free to add other database details that you know through the comments.

Auto Increment in MySQL

 The AUTO_INCREMENT attribute can be used to generate a unique identity for new rows:

Here we will list down the sample connection urls used in the jdbc examples at javajee.com.

Driver names include ojdbc5.jar for java 5,  ojdbc6.jar for java 6 etc.

Here we discuss examples for different cases of usage for stored procedures and stored functions. Please refer to the note on ‘Stored Procedures and Stored Functions in MySQL’ for more theory, details and explanations.

A stored routine allow users to define a set of statements that they can later call together. Stored procedures and stored functions are the two types of stored routines in MySQL. A stored procedure takes in zero or more input parameters and runs specified SQL statements. A stored function takes in zero or more parameters, runs specified SQL, and returns exactly one scalar value.
