Context: CREATE TABLE table_name_8 (mpg_uk_urban__cold_ VARCHAR, l_100km_urban__cold_ VARCHAR, engine_capacity VARCHAR, fuel_type VARCHAR, mpg_uk_extra_urban VARCHAR)
Question: What is the mpg-UK urban (cold) for a fuel type of diesel, extraurban MPG in the UK over 68.9, engine capacity of 1422, and L/100km urban (cold) over 5.1?
Answer: SELECT mpg_uk_urban__cold_ FROM table_name_8 WHERE fuel_type = "diesel" AND mpg_uk_extra_urban > 68.9 AND engine_capacity = 1422 AND l_100km_urban__cold_ > 5.1
