Table schema:
CREATE TABLE table_name_21 (aam_member VARCHAR, city VARCHAR, astc_member VARCHAR, aam_accredited VARCHAR, state VARCHAR)

Question: What is AAM Member, when AAM Accredited is No, when State is California, when ASTC Member is Yes, and when City is Sacramento?
SQL: SELECT aam_member FROM table_name_21 WHERE aam_accredited = "no" AND state = "california" AND astc_member = "yes" AND city = "sacramento"
