Table schema:
CREATE TABLE table_name_93 (population_density INTEGER, population__2011_ VARCHAR, population__2006_ VARCHAR, county VARCHAR, area__km²_ VARCHAR)

Question: In the County of Prince, what was the highest Population density when the Area (km²) was larger than 3.02, and the Population (2006) was larger than 786, and the Population (2011) was smaller than 1135?
SQL: SELECT MAX(population_density) FROM table_name_93 WHERE county = "prince" AND area__km²_ > 3.02 AND population__2006_ > 786 AND population__2011_ < 1135
