字符串中的Teradata转义字符

Question

I have some query to match a URL address, but the URL contains a special character '?' which I don't know how to escape.

the query is like:

select *
from table
where url = 'www.someaddress.com/**?something**=sth';

Any ideas?

Answer 1

You need to use an ESCAPE.

where url = 'www.someaddress.com/**?something**=sth';

would be

where url = 'www.someaddress.com/**@?something**=sth' ESCAPE '@';
