Hello Mr. Nicholas,
You can try the following: THIS IS WHAT I TRIED TO SOLVE YOUR PROBLEM, BUT IN ORACLE DBMS
(SORRY I DON'T HAVE POSTGRESQL INSTALL ON MY COMPUTER)
i GUESS YOU CAN TRY TO CHANGE THE SQL COMMANDS IN POSTGRESQL
create table numbers (
id number not null primary key,
description varchar2(100)
);
insert into numbers values (300, 'Three hundred (300)');
insert into numbers values (350, 'Three hundred fifty (350)');
insert into numbers values (6709, 'Six thousand seven hundred and nine (6709)');
select id, description, substr(description, instr(description, '(') +1, instr(description, ')')-(instr(description, '(') +1)) extracted_character
from numbers;
This is the Results: ID DESCRIPTION EXTRACTED_CHARACTERS
----------------------------------------------------------------------------------------------------------------
300 Three hundred 300
350 Tree hundred fifty 350
6709 Six thousand seven hundred and nine 6709 But if you run the following query you will get exactlly what: select substr(description, instr(description, '(') +1, instr(description, ')')-(instr(description, '(') +1)) extracted_character
from numbers: This is the Results: EXTRACTED_CHARACTERS
-------------------------
300
350
6709
