Ответить------ MySQL Solution ------
select cust_name, email
from feedback
where email REGEXP'^[A-Za-z][A-Za-z0-9_.-]*@[A-Za-z]+\\.[A-Za-z]{2,3}$' ;
SELECT email
FROM feedback
WHERE email ~ '^[a-zA-Z][a-zA-Z0-9_.-]*@[a-zA-Z]+\.[a-zA-Z]{2,3}$';
What if I want to create a new column in an existing table with a REGEX formula to get the Invoice number from a column in that table.
ОтветитьSo cool! This is the first time I've heard about regular expressions and they seem super useful. Thanks for sharing!
ОтветитьYour videos are great.
Do you think you can also do a small tutorial video on REGEX with a couple more problems? I tried searching in your channel but could not find. It would be really helpful.
Brilliant! I'm loving this series. It's sending me into areas of SQL I never thought about.
ОтветитьCommendable. Thanks for putting this much effort.
ОтветитьAwesome! Find new concepts with great explaination. Thank you.
Ответитьselect * from feedback
where email like '[a-zA-Z]%@[a-zA-Z]%.[a-zA-Z]%'
and email not like '%[@#]%@[a-zA-Z]%.[a-zA-Z]%'
and charindex('.',REVERSE(email)) between 3 and 4;
