QComboBox.curfrentText() 不工作 - 我总是得到 TypeError: execute() argument 1 must be str, not tuple

Question

What's wrong with my sqlstr

def clicker(self):
        cursor = self.conn.cursor()
        sqlstr = ('''
                  SELECT t1.column3, t2.column2, t2.column3, t2.column4
                  FROM t1
                  INNER JOIN t2 ON t1.id_number = t2.id_number
                  WHERE t1.column3 = ? AND t2.column2 = ?''',
                  (self.qcombobox1.currentText()), (self.qcombobox2.currentText()))

I am getting TypeError: execute() argument 1 must be str, not tuple

Thanks in advance...

您将execute() sqlstr作为参数，尝试用execute(*sqlstr)将元组解包为不同的参数。
