我正在寻找内置UDF或任何其他方法,以便在我的凤凰表中将字符串列的值转换为整数,以便使用SELECT和ORDER BY进行排序。我搜索了apache语言手册,但没有用。任何其他建议也欢迎。

我尝试了以下方法,但没有工作
from appium import webdriver
import unittest
import os
class LoginTests(unittest.TestCase):
def setUp(self):
desired_caps = {}
desired_caps['platformName'] = 'iOS'
desired_caps['platformVersion'] = '11.0'
desired_caps['deviceName'] = 'iPhone Simulator' # Run on simulator
desired_caps['bundleId'] = 'com.matchbook.MatchbookApp'
desired_caps['app'] = os.path.abspath('/Users/majdukovic/Library/Developer/Xcode/DerivedData/MatchBook-bgvchkbwrithuaegnjgpoffewdag/Build/Products/Debug-iphonesimulator/MatchBook.app') # Path to .app
self.wd = webdriver.Remote('http://0.0.0.0:4723/wd/hub', desired_caps)
self.wd.implicitly_wait(60)
loginButton = self.wd.find_element_by_id("JOIN/LOGIN") # Button ID
self.assertTrue(loginButton.is_displayed())
loginButton.click()
if __name__ == '__main__':
suite = unittest.TestLoader().loadTestsFromTestCase(LoginTests)
unittest.TextTestRunner(verbosity=2).run(suite)

TO_NUMBER返回十进制,但您可以将结果转换为INTEGER
从MY_DB中选择CAST(TO_NUMBER(MY_COLUMN)作为整数)
答案 1 :(得分:0)
select TO_NUMBER(values) from test_table;
