sqliteHow do I use SQLite keywords to query a database?
To query a database using SQLite keywords, you can use the SELECT
statement. This statement is used to retrieve data from a table in the database. For example, the following code will select all rows from the table users
:
SELECT * FROM users;
The output of this statement will be a list of all the rows in the users
table.
You can also use the WHERE
clause to filter the results of the query. For example, the following code will select all rows from the users
table where the age
column is greater than 18:
SELECT * FROM users WHERE age > 18;
The output of this statement will be a list of all the rows in the users
table that have an age greater than 18.
You can also use the ORDER BY
clause to sort the results of the query. For example, the following code will select all rows from the users
table and sort them by the name
column in descending order:
SELECT * FROM users ORDER BY name DESC;
The output of this statement will be a list of all the rows in the users
table sorted in descending order by the name
column.
Other SQLite keywords that can be used to query a database include GROUP BY
, HAVING
, LIMIT
, and JOIN
. For more information about these keywords and how to use them, please refer to the SQLite documentation.
