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_8669 ( "Province" text, "Capital" text, "Population at 2010 Census" real, "Area (km\u00b2)" real, "Density (2010)" real, "Geographical unit" text, "Number of Cities (kota)" real, "Number of Regencies (kabupaten)" real, "Number of Districts (kecamatan)" real, "Villages" real )

### Question ###
What is the sum of the number of cities (kota) with an area less than 47,799 km , the capital yogyakarta, and a 2010 density greater than 1,138?

### Accurate SQL ###

SELECT SUM("Number of Cities (kota)") FROM table_8669 WHERE "Area (km\u00b2)" < '47,799' AND "Capital" = 'yogyakarta' AND "Density (2010)" > '1,138'
