Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: 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?

### Accurate SQL ###

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
