A. SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. It is a database, which is zero-configured, which means like other databases you do not need to configure it in your system.SQLite engine is not a standalone process like other databases, you can link it statically or dynamically as per your requirement with your application. SQLite accesses its storage files directly.The URL to connect with SQLite database is jdbc:sqlite:test.db and, the driver class name to connect to it is org.sqlite.JDBC.Before you proceed with the example:Download latest version of sqlite-jdbc-(VERSION).jar from sqlite-jdbcrepository.Add downloaded jar file ...

You can call a function using CallableStatement object just like stored procedures, to call a function using a JDBC program you need to.Connect to the database.Create a PreparedStatement object and to its constructor pass the function call in String format.Set values to the place holders.Execute the Callable statement.Following is the query to call a function from JDBC:{? = call getDob(?)}As you observe the query contains place holders (?) just like prepared and callable statements.In the above query, the first place holder represents the return value of the function and the second placeholder represents the input parameter.You need to register the ...

Like procedures, you can also create function in a database and store them.SyntaxFollowing is the syntax of creating a function in a(MySQL) database:CREATE FUNCTION Function_Name(input_arguments) RETURNS output_parameter BEGIN declare variables; statements . . . . . . . . . . return data_type; ENDTo create a function in a database using JDBC API you need to:Register the driver: class using the registerDriver() method of the DriverManager class. Pass the driver class name to it, as parameter.Establish a connection: Connect ot the database using the getConnection() method of the DriverManager class. Passing ... Read More

A. Stored procedures are sub routines, segment of SQL statements which are stored in SQL catalog. All the applications that can access Relational databases (Java, Python, PHP etc.), can access stored procedures.Stored procedures contain IN and OUT parameters or both. They may return result sets in case you use SELECT statements. Stored procedures can return multiple result sets.You can call a stored procedure using the following syntax:CALL procedure_name (input_parameter1, input_parameter2, input_parameter3)JDBC provides a standard stored procedure SQL escape syntax using which you can procedures in all RDBMSsTo call a stored procedure using a JDBC program you need to:Register the driver: ...
