CREATE TABLE table_name_24 (rd__number VARCHAR, reg_gp VARCHAR, pick__number VARCHAR)

What is the rd number where the reg GP is 0 and the pick is 150?
SELECT COUNT(rd__number) FROM table_name_24 WHERE reg_gp = 0 AND pick__number = 150
SELECT COUNT("rd__number") FROM "table_name_24" WHERE "pick__number" = 150 AND "reg_gp" = 0
