SQLite SELECT DISTINCT Keyword
The SQLite SELECT DISTINCT keyword is used to select different (distinct) data from a database table. It eliminates any duplicate records and fetches only unique records.
Syntax
The syntax for using SELECT DISTINCT keyword in SQLite is given below:
SELECT DISTINCT column1, column2, .... FROM table_name;

|---|---|---|---|---|
| 1 | John | London | 25 | 3000 |
| 2 | Marry | New York | 24 | 2750 |
| 3 | Jo | Paris | 27 | 2800 |
