That would depend on the SQL file itself.
I'm assuming your SQL file is a backup of a mysql database.
If the backup is formatted in a way that is compatible than wordpress, then yes it will integrate well if you use something such as PHPmyAdmin to import it.
Otherwise, if the names and values of the fields/rows/tables of the backup are not what Wordpress goes by, you'll be trying to fit a square block into a sphere holder.
You can still view the SQL file yourself and salvage whatever data is inside it, but you didn't give much information O.o
