How to add a column in a table
Consider a situation where the requirement of the
client gets changed and you have asked to modify the structure of the table. In
reality it is the work of the database administrator but as a Java programmer
you should know how you can modify the structure of the table. The problem is
that we have to add a new column to our database by using the java program.
There is no need to get panic. What we simply need is to use a query for
adding a new column in the database table.
To get the desired result firstly we need to make a
connection with our database. After connection has been established pass the
query in the prepareStatement() for adding new column in the database.
This method will return the PreparedStatement object. By the object of
the PreparedStatement we will call the executeUpdate() which will
tell the status of the table.
