Identifiers

Identifiers are the names of tables, columns, indexes and other metadata elements used in a query. Identifiers must start with a letter and can only contain letters, digits, and underscores. They are implicitly converted to lower case.

INSERT INTO test VALUES (1, 'A single quote '' needs to be doubled')

A single quote ' needs to be doubled
