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 where the id is 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;
