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_64500 ( "School" text, "Location" text, "Mascot" text, "County" text, "Year Joined" real, "Previous Conference" text, "Year Left" real, "Conference Joined" text )

### Question ###
What year did the Ingots, who left after 2007, join?

### Accurate SQL ###

SELECT COUNT("Year Joined") FROM table_64500 WHERE "Mascot" = 'ingots' AND "Year Left" > '2007'
