You can use literal values normally the same way you use column names in the SELECT clause. This will select all the columns from the students table only:Ī literal value is a constant value that can be specified in the select statement. This will select all the columns from only the table “tablename”. This will select all the columns from both the tables students and the departments tables: INNER JOIN Departments ON Students.DepartmentId = Departments.DepartmentId This command will select all the columns from all the referenced tables (or subqueries) in the FROM clause. In the SELECT clause, you can select not only a column name but you have a lot of other options to specify what to select. Now you are ready to run any type of query on the database. Step 2) Open the database “ TutorialsSampleDB.db” by the following command: Open My Computer and navigate to the following directory “ C:\sqlite” and.Note that, for all the following examples, you have to run the sqlite3.exe and open a connection to the sample database as flowing: In the from clause, you can specify one or more table or subquery to select the data from, as we will see later on the tutorials. The FROM clause is used to specify where do you want to select data. But before the select clause, let’s see from where we can select data using the FROM clause. In the SELECT clause, you state what to select. The SELECT clause is the main statement you use to query an SQLite database. To write SQL queries in an SQLite database, you have to know how the SELECT, FROM, WHERE, GROUP BY, ORDER BY, and LIMIT clauses work and how to use them.ĭuring this tutorial, you will learn how to use these clauses and how to write SQLite clauses.
