sqliteHow can I use SQLite functions to achieve a specific task?

SQLite functions can be used to achieve a specific task by writing an SQL query. For example, to get all the records of a table named users:

SELECT * FROM users;

This will return all the records of the users table.

Code explanation

• SELECT: a keyword used to specify which columns to return
• *: a wildcard used to select all columns
• FROM: a keyword used to specify from which table to select
• users: the name of the table from which to select

Other SQLite functions can be used to achieve other tasks. For example, to get the sum of all values in a score column of the users table:

SELECT SUM(score) FROM users;

This will return the sum of all values in the score column.

Code explanation

• SELECT: a keyword used to specify which columns to return
• SUM: a function used to calculate the sum of a column
• score: the name of the column to sum
• FROM: a keyword used to specify from which table to select
• users: the name of the table from which to select
