Extracting date from the sql query string in python

Question

I have a case where I have to extract date from a SQL query that I am running through a python script.

This is the query:

select * from COLL_DS2 where TRANSACTION_DATE between '2021.02.28' and '2021.04.08' order by CREATION_DATE

I want to extract '2021.02.28' and '2021.04.08' from the query string.

Any help please? Thanks in advance

Answer 1

You may use re.findall :

sql = "select * from COLL_DS2 where TRANSACTION_DATE between '2021.02.28' and '2021.04.08' order by CREATION_DATE"
dates = re.findall(r"'(\d{4}\.\d{2}\.\d{2})'", sql)
print(dates)  # ['2021.02.28', '2021.04.08']

Answer 2

Another way to write it. Tim Biegeleisen solution is good, just need to add the import re

import re
Query = "select * from COLL_DS2 where TRANSACTION_DATE between '2021.02.28' and '2021.04.08'"
ldat = re.findall('\d+\.\d+\.\d+', Query)

print(ldat)
# ['2021.02.28', '2021.04.08']
