When querying objects such as tables and columns with upper case letters in their name, remember to enclose the identifier name in quotes. For example:
SELECT * FROM "Company". Postgres changes identifier names to lower case unless they are quoted. The same applies when creating objects in Postgres. For example,
CREATE TABLE DEPARTMENT(id INT) creates a table named
department in Postgres. For more information about how quoted and unquoted identifiers are treated by Postgres, see
Identifiers and Key Words in the PostgreSQL documentation.
