You're trying to return a value inside a callback, which is useless. What
you need to do instead is add a callback parameter to `sql_file` and call
the callback with the `data` value (or `error` if that is set) using the
node callback style:
function sql_file(cb) {
var fileName = "./SQLs/inventory.sql";
fs.readFile(fileName, function(err, buffer) {
if (err) return cb(err);
return cb(null, buffer.toString());
});
}
// use the function ...
sql_file(function(err, sqlstatement) {
if (err) throw err;
console.log('sql statement is: ' + sqlstatement);
});
