SELECT 1
SELECT 1 + 2
SELECT LEN("Clang Query Language")
SELECT "One" IN ("One", "Two", "Three")
SELECT "Clang Query Language" LIKE "%Query%"

SELECT name, source_loc FROM functions WHERE m_function(ast_function, (m_public() && m_constructor()) || m_default_constructor());

SELECT * FROM functions
SELECT COUNT(name) from functions WHERE return_type = "int"
SELECT DISTINCT name AS function_name FROM functions
SELECT name, source_loc FROM functions WHERE m_function(ast_function, m_constructor());
SELECT name, source_loc FROM functions WHERE m_function(ast_function, m_copy_constructor());
SELECT name, source_loc FROM functions WHERE m_function(ast_function, m_move_constructor());
SELECT name, source_loc FROM functions WHERE m_function(ast_function, m_pure_virtual());

SELECT * FROM globals
SELECT COUNT(name) from globals WHERE type = "int"
SELECT * FROM globals WHERE is_volatile
