Table schema:
CREATE TABLE table_name_12 (sfc_in_g__kn INTEGER, engine_type VARCHAR, sfc_in_lb__lbf·h_ VARCHAR)

Question: What is the highest SFC in g/(kN*s) for Rolls-Royce/Snecma Olympus 593 engines and SFCs under 1.195 lb/(lbf*h)?
SQL: SELECT MAX(sfc_in_g__kn) AS ·s_ FROM table_name_12 WHERE engine_type = "rolls-royce/snecma olympus 593" AND sfc_in_lb__lbf·h_ < 1.195
