Flask ve MySQL hatası nasıl çözülür?

@app.route("/dashboard")
def bookingOwners():
 cursor = mysql.connection.cursor()
 sorgu = "SELECT * FROM masters WHERE username IN(SELECT username FROM booking WHERE owner_id IN(SELECT id FROM masters WHERE username = %s))"
 sorgu2 = "SELECT * FROM masters WHERE username IN(SELECT username FROM booking WHERE username=%s)"
 result2 = cursor.execute(sorgu2,(session["username"],))
 result = cursor.execute(sorgu,(session["username"],))
 if result > 0:
 bookingOwners = cursor.fetchall()
 return render_template("dashboard.html",bookingOwners = bookingOwners)
 if result2 > 0:
 bookingOwners = cursor.fetchall()
 return render_template("dashboard.html",bookingOwners = bookingOwners)
 else:
 return render_template("dashboard.html")
