Re: Control PhoneNumber Via SQL

Hi All,

Thanks for the suggestions especially the article for formatting
international phone numbers.

I also implement the suggestion of Sir Wolfgang:

cur_t.execute("""
SELECT mobilenumber,
CASE
WHEN mobilenumber ~'^0[1-9]'
THEN regexp_replace(mobilenumber, '0', '+63')
ELSE mobilenumber
END
FROM studeprofile
ORDER BY lastname
""")
x = cur_tdc.fetchone()
print x[1]

['09xxxxxxxxx', '+639xxxxxxxxx']

The output shows 2 values in a list. I only need to get the one that starts
with country code. I can do it by using x[1]. I think this has been
explained by Sir Adrian in my previous question. I'll review that.
