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_12213 ( "Name" text, "GP-GS" text, "Gain" real, "Loss" real, "Long" real, "Avg/G" real )

### Question ###
What's the total long for more than 24 loss, a gain over 273, and an avg/g of 207.8?

### Accurate SQL ###

SELECT SUM("Long") FROM table_12213 WHERE "Loss" > '24' AND "Gain" > '273' AND "Avg/G" = '207.8'
