WHERE Clause

The WHERE clause specifies any filters to apply to the data. This allows you to select only a subset of the data in which you are interested. Logically the WHERE clause is applied immediately after the FROM clause.

Examples​

-- select all rows that have id equal to 3
SELECT *
FROM table_name
WHERE id=3;
-- select all rows that match the given case-insensitive LIKE expression
SELECT *
FROM table_name
WHERE name ILIKE '%mark%';
-- select all rows that match the given composite expression
SELECT *
FROM table_name
WHERE id=3 OR id=7;
