Hello,
I have query phone number in database as follows:
[123) 456-7890
(123) 456-7890
When I query like this:
SELECT * FROM phone
WHERE phone_number ~ ('^\[123' || '[-\s\)]{0,2}' || '456' || '[-\s\)]{0,2}'
|| '7890')
it use Index but if I query like this (notice first character is
open parenthesis instead of open square blacket ) :
SELECT phn_fk_key FROM phn WHERE
phn_fk_table = 14
AND llx_decrypt(phn_phone_enc) ~ ('^\(123' || '[-\s\)]{0,2}' || '456' ||
'[-\s\)]{0,2}' || '7890')
It doesn't use Index....
co-worker suggested me to use chr(40) instead so I tried this:
SELECT phn_fk_key FROM phn WHERE
phn_fk_table = 14
AND llx_decrypt(phn_phone_enc) ~ ('^\' || chr(40) || '123' || '[-\s\)]{0,2}'
|| '456' || '[-\s\)]{0,2}' || '7890')
No success...
Also { and period doesn't seems to use index either.... but } ) [ ] $ #
works.
Could you guide me to right direction for me please?
Thank you very much for your time in advance.
