I have a table containing regular expresion patterns for matching phone numbers with the mobile operators.
For instance, my phone number is '+385911234567', and the regexp for this mobile operator is: "^\+38591\d{7}$". Now, when I do a regexp match in a single select, it behaves as expected: octopussy2=# select '+385911234567' ~ '^\\+38591\\d{7}$'; ?column? ---------- t (1 row) Now, as I've mentioned, I have a table with operators and their patterns for phone numbers: octopussy2=# select * from operators; operator_id | operator_name | operator_phonenumber_pattern -------------+---------------+------------------------------ 1 | FreeSMSC | ^\\+38590\\d{6,7}$ 2 | VipNet | ^\\+38591\\d{7}$ 3 | T-Mobile | ^\\+3859[9|8]\\d{6,7}$ 4 | Tele2 | ^\\+38595\\d{7}$ (4 rows) Now, if I construct my query like this: octopussy2=# select '+385911234567', operator_phonenumber_pattern, '+385911234567' ~ operator_phonenumber_pattern from operators; ?column? | operator_phonenumber_pattern | ?column? ---------------+------------------------------+---------- +385911234567 | ^\\+38590\\d{6,7}$ | f +385911234567 | ^\\+38591\\d{7}$ | f +385911234567 | ^\\+3859[9|8]\\d{6,7}$ | f +385911234567 | ^\\+38595\\d{7}$ | f (4 rows) Why do I get all the "f"'s? I tought that the operator_id 2 should return "t", esp. when I wrote the first query it seems that the regex match was ok. Or I can't do regexp matching from the table columns?
