How to Select a substring in Oracle SQL up to a specific character?

i have a column containing hostnames in the format of :
oraclehost.server.region.company.net
How to extract the oraclehost part from the hostname i.e the string before the first ..
Please sugges.Thanks.
SELECT REGEXP_SUBSTR(HOSTNAMES, '[^.]+', 1, 1) FROM MYTABLE;
Alternatively, substr + instr combination which would probably perform better for large data sets:
substr(hostnames, 1, instr(hostnames, '.') - 1)
For example:
SQL> with mytable (hostnames) as
2 (select 'oraclehost.server.region.company.net' from dual)
3 select substr(hostnames, 1, instr(hostnames, '.') - 1) result
4 from mytable;
RESULT
----------
oraclehost

I need to parse a string like 112^3^1^1^ into separate values.
The first ('112') is order_no, second one is line_no, third one is release_no, and the fourth one is receipt_no.
What kind of regex can I use in Oracle?
with demo (str) as
( select '112^3^1^1^' from dual )
select str
, regexp_substr(str,'[^^]+',1,1) as order_no
, regexp_substr(str,'[^^]+',1,2) as line_no
, regexp_substr(str,'[^^]+',1,3) as release_no
, regexp_substr(str,'[^^]+',1,4) as receipt_no
from demo;
STR ORDER_NO LINE_NO RELEASE_NO RECEIPT_NO
---------- ---------- --------- ------------ ----------
112^3^1^1^ 112 3 1 1
This depends on each component having a value, because the pattern it is using is 'one or more characters that are not ^'. It would need a bit of tweaking if a value was missing, e.g. '112^3^^1^' (no release_no).

How to concatenate text from multiple rows into a single text string in SQL Server
(47 answers)
Closed 8 years ago.
Using simple query , I can do something like
SELECT hobbies FROM peoples_hobbies WHERE person_id = 5;
and get:
shopping
fishing
coding
but instead I just want 1 row, 1 col:
shopping, fishing, coding
for ref-- Can I concatenate multiple MySQL rows into one field?
I want to do this in sql server ??
SQL Server doesn't have great support for aggregate string concatenation. But you can do:
select stuff((select ', ' + hobbies
from peoples_hobbies
where person_id = 5
for xml path ('')
), 1, 2, '') as hobbies;
