SQLite supports neither RIGHT OUTER JOIN nor FULL OUTER JOIN.The following are the list of unsupported features and limitations in SQLite: SQLite limitations and Unsupported Features Just attach those databases, and then you can access all the databases’ objects (tables, views, etc.) at the same time. With SQLite, you can work at multiple databases on the same session on the same time.With this statement, you can tell SQLite to try to do an insert on a table and if it found rows with the same primary keys, then update them with the values from the inserted values. SQLite variables are dynamically typed, meaning that the type of the variable is not determined until it is assigned a value, and not defined at the time of declaration.A broad range of SQLite APIs – SQLite provides APIs for a broad range of programming language, for example.Net languages (Visual Basic, C#), PHP, Java, Objective C, Python and a lot of other programming languages.For example, if you have a varchar(200) column, and you put a 10 characters’ length value on it, then SQLite will allocate only 20 characters’ space for that value and not the whole 200 space. So SQLite will allocate only space a field needs. SQLite offers an efficient way of storing data, the length of the columns is variable and is not fixed.It can also be used on a lot of embedded operating systems like Symbian, and Windows CE. It can be used on a broad range of platforms like Windows, Mac OS, Linux, and Unix. SQLite is cross-platform database management system.SQLite is an open source, no commercial license required to work with it. Copy the SQLite libraries in your computer, and you are ready to learn.įollowing guide will help you determine whether you should choose SQLite for your next project As we explained earlier, no installation or configuration is required. When you need a database system for learning and training purposes, SQLite is a good fit.For example, you are developing a program where you have to perform calculations on some records. You can create an SQLite database and insert the records there, and with only one query, you can select the records and perform calculations. It gives you an easy and efficient way to process using in-memory variables.You can extract the data in a format you want to display in your application. You can load the data into an SQLite in-memory database and execute the desired queries. If you want to do processing on some data within an application, you can use SQLite as a temporary dataset.
