英文:
store values from snowflake table into variable in python
问题
我需要从Snowflake表中获取值，并使用Python将其存储到变量中。
之后，我需要将该值与文件名（product_yyyymmdd.csv）合并。
以下是我的代码：
HA_file_path = '''select CONFIG_VALUE from CONFIGURATIONS where CONFIG_NAME ='HA' '''
file_path = cs.execute(HA_file_path)
它没有返回任何值，而是打印了类似于以下内容：
snowflake.connector.cursor.SnowflakeCursor object at 0x7fefbe68a070
有任何帮助吗？

after that i need to merge that value with file name(product_yyyymmdd.csv).
below is my code
HA_file_path = ''' select CONFIG_VALUE from CONFIGURATIONS where CONFIG_NAME =\ 'HA''''
-- syntax is correct
file_path = cs.execute(HA_file_path)
its not returning any value and printing something like this :
snowflake.connector.cursor.SnowflakeCursor object at 0x7fefbe68a070

在这一行中：file_path = cs.execute(HA_file_path)，你将一个变量分配给了游标对象，但你没有获取结果。如果你想将表中的一个值存储为变量，你可以在execute之后使用fetchone方法：
cs.execute(HA_file_path)
file_path = cs.fetchone()[0]
print(file_path)
英文:
In the line: file_path = cs.execute(HA_file_path) you assigned a variable to the cursor object, but you are not fetching results. If you want to store just one value from the table as a variable, you can use fetchone method after execute:
cs.execute(HA_file_path)
file_path = cs.fetchone()[0]
print(file_path)
