The download is categorized by versions, so browse a directory for a specific version you want: 3.5.9, 3.6.16, 3.7.2, etc. Download SQLite JDBC driverYou can download the latest version of JDBC driver for SQLite here. Although there is no official JDBC driver library from there is one provided by – an XML Database Management System project. As long as the stored procedure is updated to reflect the change, the application won’t break.SQLite is a simple, small, fast, reliable, server-less, zero-configuration and no-installation SQL database library which is running in-process with the client application. If there’s a structural change to the database, if some tables get renamed for example, this need not break the application. Therefore, a stored procedure can provide advanced database functionality for users who wouldn’t normally have access to these tasks, but this functionality is made available in a tightly controlled way. Users can execute a stored procedure without having to execute any of the statements directly. The only network traffic will be the parameters supplied and the results of any query. Running the code on the database server (as a stored procedure) eliminates the need to send this code over the network. Reduced network traffic: If you send many lines of SQL code over the network to your database server, this will impact on network performance.When you send a query from your application, it requires the database to compile and optimise your SQL code every time it runs. This means that it will execute a lot faster than sending a query from your application to the database. Faster execution: Stored procedures are parsed and optimised as soon as they are created and the stored procedure is cached.Stored procedures provide faster code execution and reduce network traffic. The application can then pass parameters to the stored procedure for processing, rather than processing it itself. You can avoid duplicate code turning up all over an application by having the business logic handled in one place – the stored procedure. You can even call it from multiple applications. You can write a stored procedure once, then call it again and again, from different parts of the application. Here are some of the main advantages of stored procedures: Modular programming Changing this value would process a different customer. The above passes a parameter called CustomerId with a value of 7. In SQL Server, you could call the above stored procedure like this: EXECUTE GetCustomer = 7 You can call (or execute) a stored procedure with a single line of code. Prefix the parameter name with the symbol.įor example to add a parameter called CustomerId with a datatype of Integer: CREATE PROCEDURE GetCustomer int ASĬheck with your DBMS documentation for the exact syntax to use for that DBMS. If the stored procedure is to accept parameters, add these and their data type to the first line. The exact syntax will depend on which DBMS you use.įor example, to create a stored procedure in SQL Server called GetCustomer, start with the following: CREATE PROCEDURE GetCustomer ASįollow that with the SQL code for the stored procedure. Stored procedures are created using the CREATE PROCEDURE statement. Stored procedures can also accept parameters. Stored procedures often contain conditional programming such as IF. However, one of the benefits of stored procedures is that they allow you to store complex scripts on the server. Stored procedures can be as simple or as complex as you like. A stored procedure is a series of SQL statements compiled and saved to the database.
