I'm using the DB2 10.1 fixpack 1 Enterprise Edition on Linux.
I would like to drop function
I checked if the function exists with:
select * from syscat.functions where funcschema = 'TEST' and funcname = 'REC1'
and have got the output:

I tried to drop a function with:
drop function TEST.REC1
And I got the error:
SQL0204N "TEST.REC1" is an undefined name. SQLSTATE=42704
How to drop this function?
Try
ALTER MODULE IZPISI DROP FUNCTION TEST.REC1

select current_setting('my.session_id');

-----------------
14
(1 row)
select set_config ( 'my.session_id', 15::text , true) ;

select current_setting('my.session_id');

As seen above, SET is working, but set_config is behaving slightly differently. Probably I am missing something.
set my.session_id = 14;
select current_setting('my.session_id');
current_setting
-----------------
14
(1 row)
select set_config ( 'my.session_id', 15::text , false) ;
set_config
------------
15
(1 row)
select current_setting('my.session_id');
current_setting
-----------------
15
(1 row)
as per manual:
Sets the parameter setting_name to new_value, and returns that value. If is_local is true, the new value will only apply during the
current transaction. If you want the new value to apply for the rest of the current session, use false instead.
I have following tables with Table1 with rows: >25million rows

I am running following postgres query through dbvisualizer. At the moment, the query is running very slow (still waiting for the output.. >10 mins).
SELECT
chrom, strand, ref_base, alt_base, pos, gene_ensembl_identifier, mut.seq_window_mut_9mers substring
FROM table1
LEFT JOIN table2 ON mer9.seq_window_mut_9mers = table1.seq_window_mut_9mers;
How can I make it run faster? Any suggestions will be really helful.
Thanks
It looks like you don't really need to join with table2. You can generate it on the fly with substring function, like this:
select
table1.*,
offsets.start,
substring(seq_window_mut_9mers from offsets.start for 9) as substring
from
table1,
(select generate_series(1,9) as start) as offsets;
It will be much faster that a join.
I have some performance issue when querying on dictionary views. When using RULE hint the query is very fast. What can be the problem ? I have optimizer_mode=RULE in init.ora. Oracle 12.1.0.2.0 with p26635880_121020_Linux-x86-64.zip patch applied

I have a text looking like this:
>Sequenz: Test 1
MTEITAAMVKELRESTGAGMMDCKNALSETNGDFDKAVQLLREKGLGKAAKKADRLAAEG
>Sequenz 2 1234 Organism: Treponema
MTEITAAMVKELRESTGAGMMDCKNALSETNGDFDKAVQLLREKGLGKAAKKADRLAAEG
>Sequenz 3
MTEITAAMVKELRESTGAGMMDCKNALSETNGDFDKAVQLLREKGLGKAAKKADRLAAEG
There is not necessarily a blank line between the text chunks and it might be a various number of lines of 'MTEITAAMVKELRESTGAGM'. The only thing, which is known for sure is a > before each line.
I want resulting in a table like this:
HEADER
----------
Sequenz: Test 1
----------
Sequenz 2 1234 Organism: Treponema
----------
Sequenz 3
I tried:
SELECT regexp_matches(regexp_split_to_table( 'text from above', '\n>'),'([A-Z,a-z,0-9]+\s)');
resulting in
HEADER
----------
Sequenz
----------
Sequenz
----------
Sequenz
and
Select regexp_split_to_table('text from bove', '[\\\n>+(.)\\\n]+')
resulting in
HEADER
----------
----------
Sequenz: Test 1
----------
MTEITAAMVKELRESTGAGMMDCKNALSETNGDFDKAVQLLREKGLGKAAKKADRLAAEG

----------
Sequenz 2 1234 Organism: Treponema

----------
----------
Sequenz 3
----------
MTEITAAMVKELRESTGAGMMDCKNALSETNGDFDKAVQLLREKGLGKAAKKADRLAAEG
Try this:
SELECT split_part(regexp_split_to_table(trim(leading '>' from '>Sequenz: Test 1
MTEITAAMVKELRESTGAGMMDCKNALSETNGDFDKAVQLLREKGLGKAAKKADRLAAEG
>Sequenz 2 1234 Organism: Treponema
MTEITAAMVKELRESTGAGMMDCKNALSETNGDFDKAVQLLREKGLGKAAKKADRLAAEG
>Sequenz 3
MTEITAAMVKELRESTGAGMMDCKNALSETNGDFDKAVQLLREKGLGKAAKKADRLAAEG'), E'>'),E'\n', 1) AS res
Remove trim() function if you want to keep first empty row.

I am trying to connect to oracle and execute one query
I have created abc.BAT
#ECHO off
sqlplus -S scott/tiger#orcl
ECHO SPOOL text.out
select * from emp;
ECHO SPOOL OFF
But i am not able to get any output when i execute abc.bat ,Whats wrong in this?
I suspect that you want to separate the SQL*Plus commands from the BAT file.
For example, if you create a SQL*Plus script (abc.sql)
C:\Users\jcave>type abc.sql
spool text.out;
select * from emp;
spool off;
exit;
And then create a batch file that calls SQL*Plus and passes in the SQL*Plus script you just created (abc.bat)
C:\Users\jcave>type abc.bat
sqlplus scott/tiger #abc.sql
Then when you invoke the BAT file, you'll get the output you want
C:\Users\jcave>abc.bat
C:\Users\jcave>sqlplus scott/tiger #abc.sql
