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_59911 ( "Squad No." real, "Name" text, "Position" text, "League Apps" text, "League Goals" real, "FA Cup Apps" text, "FA Cup Goals" real, "League Cup Apps" text, "League Cup Goals" real, "FLT Apps" text, "FLT Goals" real, "Total Apps" text, "Total Goals" real )

What is the sum of League Goals, when Position is 'DF', when League Cup Apps is '0', when Total Apps is '7', and when FLT Goals is less than 0?

### Accurate SQL ###

SELECT SUM("League Goals") FROM table_59911 WHERE "Position" = 'df' AND "League Cup Apps" = '0' AND "Total Apps" = '7' AND "FLT Goals" < '0'
