select 1 rn, 'A' val from dual UNION ALL
select 2 rn, 'A' val from dual UNION ALL
select 3 rn, 'B' val from dual UNION ALL

I'm trying to find a way to see if a value occurs more than once in a string. I just need to know "T/F", or "Y/N", etc.
The string will be comma delimited.
String: '1,2,3,1'
Ans: "T"
String: '1,2,3,4'
Ans: "N"
They do need to match exactly. for instance
String: '1,2,3,1a'
Ans: "N"
Using some code I found on this site, I coded this but I'm sure there's a better way. Is there??
--Check for Duplicate combination row values
BEGIN
--Query will split the string into individual pieces.
--Group the pieces to see if any 2 rows are the same
--If no rows are the same then "no_data_found" exception is thrown
SELECT 'T'
INTO vResult
[Code]...
I am using regexp_replace function to replace the string between the double quotes with the first occurance but i am able to replace first occurance but I am not getting remaining string.
For example:
select REGEXP_replace('Parent.addChildByName("DS-Id of OAL(BROBA)")||parent.add("DS-Id of OAL(BROBA)")','["]:print:+:punct::print:*["]','XXXX') from DUAL
O/P: Parent.addChildByName(XXXX)
Expected O/P : Parent.addChildByName(XXXX)||parent.add("DS-Id of OAL(BROBA)")
There's a fairly popular Ordered Hint example on the web as follows:
<CODE>
select /*+ ordered use_nl(bonus) parallel(e, 4) */
e.ename,
hiredate,
b.comm
from
emp e,
bonus b
where
e.ename = b.ename
;
</CODE>
I would like to know what the "parallel(e, 4)" clause does. Where does the "4" come from? What is "parallel" here? I also have another question: If I have 5 tables--T_OREGON, T_UTAH, T_VIRGINIA, T_TEXAS, and T_OKLAHOMA--lined up in a join right behind a FROM, coming in at row counts of
T_OREGON: [a lot of rows; a lot more than T_UTAH]
T_UTAH: [smaller than T_OREGON] 40550 rows
T_VIRGINIA: 14 rows
T_TEXAS: 66 rows
T_OKLAHOMA: 8 rows
from T_OREGON or, T_UTAH ut, T_VIRGINIA va, T_TEXAS tx, T_OKLAHOMA ok...
my question is, if an Ordered hint can be used here, is it that the smallest table (in this case T_OKLAHOMA) gets placed first in the join and the rest of the table ascension in the join doesn't matter? Or is it that T_OKLAHOMA gets placed first in the join, followed by T_VIRGINIA [at 14 rows], followed by T_TEXAS, T_UTAH, and finally T_OREGON?
My need is to locate an occurrence of symbols starting from "s." (non-capital letter), following by word (with any capital letter at the beginning) and ending with ", " (comma and space symbols).
Ex:
select 'jeklghje, s.Glkgje, u.slgjwek, 904869' as tt from dual union all
select 's.Tklgj, u.slgjwek, 23578, elslgjs' as tt from dual union all
select 's.klgj, u.ekgjes, 238573, dlsjkgj' as tt from dual
I'm looking for occurrence of "s.Glkgje, " and "s.Tklgj, ".
I think some combination of REGEXP_INSTR and REGEXP_SUBSTR should be useful, but I'm not familiar with these functions so good yet.
I have to update a column for all the records in the table with a unique contraint
ex-- select rec_no from tablename;

8
7
6

but when i am doing update tablename set rec_no=rec_no-1 i am getting unique constraint error

On AWR, I see two script that are out of ordinary, and I want to make sure that I interpret them correctly.
1) "Elap per Exec (s)" shows 3263.49 with 1 "Executions".
2) "Elap per Exec (s)" shows 3180.17 each execution with 2 "Executions".
Does this mean that this script ran for ~ 54 minutes (3263.49 / 60 seconds) for 1 "Execution" and ~ 53 minutes (3180.17 / 60 seconds) per each execution? I need to understand "Elapsed Time (s),CPU Time (s),Executions ,Elap per Exec (s), % Total DB Time" represent.
I am trying to understand "ordered" hint. I want to use it in my sql where I am using some left outer joins. I believe if I use this ordered hint it will be much faster.
But the problem is I am not able to understand the concept of this hint. As i did alot of search on this eveyone says it will be , even I got some similar references where it worked But I am getting contradicting explanation for on this.
'm using the "Highlight Words" column formating for a report. There, I'm using the item syntax: &P1_RENVOI. Problem is, when the report appear, only the first occurence of the value of item "P1_RENVOI" is in red for every field in that column.
Is this a normal feature or should all occurences be put in red?
is any way to export an Oracle database organized in manner that, both tables and constraints would be exported in the correct order.An easy sample:
- An database with 2 tables, with constraints between them. Table 1 has a FK on Table 2.
Is it possible to export both structure and data regarding the constraints, resulting in an script that makes it possibly to import it in a way that would not give me problems about constraints?

On [SQL ordered by Elapsed Time], [SQL Module] shows an indication that a SQL was executed by which process (i.e. srv_dr@ahs)outside of SQL*PLUS.If [SQL Modeule] shows as [SQL*Plus], does it mean the query was run in SQL*PLUS manually or directly?I have the SQL ID. How do I find out who, how, and exactly what time it was run?
I need to search a specific pattern from a source code. In word, I need to check whether "getCode" has been called or not, for all the string inside double-quote("). Following are sample code lines -
1.->if(val==23){ month_desc = "a sample data"; }
2.->if(val==23){ month_desc = getCode("a sample data"); }
3.->if(val==23){ month_desc = "a " + getCode("sample data"); }
4.->if(val==23){ month_desc = getCode("sample data"); var2="sample data2";}
Now, expression should be such that it will return true during check for 1, 3 and 4, although, for 3 & 4 getCode has been called for part of the String.
let's say a parameter changed in the database ex: alter system set retention_target= 1500; and i want to know what was the old value before it has been changed ,

The above function was running well. Today i have made some change as under
Create Or Replace Function Fin_Prd(V_Dte In Date,V_Rtn_Flg In Number Default 0) Return Number Is
V_Fin_Str Number;

Above function is created and working well when i use it in query in sql prompt or Toad. But problem is this that all function which used this are invalid and when i run report whose query use FIN_PRD then error is "Ora-04062. Timestamp of Fin_Prd has been changed".
I learned that Oracle uses supplemental logging mechanısm to add the changed rows to redo log files and identify the changed rows on target replication database? Is that mechanism mandatory to handle the replication of data between updated and back up databases?

I have a datablock like this
datablock name : jou_tra1_tab
No. of record dispalyed is 5
so datablock display like this

jtt_amt jtt_amt_1 ck_amt
jtt_amt jtt_amt_1 ck_amt
jtt_amt jtt_amt_1 ck_amt
jtt_amt jtt_amt_1 ck_amt

ck_amt_tot
ck_amt is checkbox..
ck_amt_tot is total of jtt_amt_1 [but total only those record whose checkbox is checked]
My task is like this When i checked checkbox whatever value in jtt_amt transfer to jtt_amt_1 field
but i can change value in jtt_amt_1 field ...i want to take addition of that changed field and show that sumation in ck_amt_tot.
I write trigger when-checkbox-changed like this
-------------------------------------------------
IF :jou_tra1_tab.ck_amt = 'Y' THEN
set_item_INSTANCE_property ('jou_tra1_tab.jtt_amt_1',CURRENT_RECORD, UPDATE_ALLOWED, PROPERTY_TRUE);
:jou_tra1_tab.jtt_amt_1 := :jou_tra1_tab.jtt_amt;
else
:jou_tra1_tab.jtt_amt_1 := 0;
END IF;
and when validation item trigger for jtt_amt_1 :
--------------------------------------------------
IF :jou_tra1_tab.ck_amt = 'Y' then
:jou_tra1_tab.ck_amt_tot := :jou_tra1_tab.ck_amt_tot + :jtt_amt_1 ;
else
:jou_tra1_tab.ck_amt_tot := :jou_tra1_tab.ck_amt_tot - :jtt_amt_1 ;

I've got a oracle install [non production, but devel] that is a tad screwed up. We moved the box and as a result changed the hostname to match the new naming scheme. Ever since then OracleEM has been somewhat confused. In anycase, I don't want OEM anyways now. Plan is to learn SQLplus.
That being said I've used emctl to shut down dbconsole, but it seems there is something somewhere that keeps restarting 2 processes that like to sit around and take up 100% cpu. I can kill them, they stay dead for a few hours then crop up again.I was able to find this out about them:
[jmacdonald@devoracle ~]$ ps auxwww|grep 2033
oracle 20334 84.1 12.3 994052 255824 ? Rs Aug10 1740:43 ora_j000_orcl
oracle 20336 80.9 14.1 998140 294288 ? Ss Aug10 1674:18 ora_j001_orcl
And then this, which caused me to conlucde its OracleEM:
SELECT sess.process, sess.status, sess.username, sess.schemaname, sql.sql_text
FROM v$session sess,
v$sql sql
WHERE sql.sql_id(+) = sess.sql_id
AND sess.process in (20334,20336)
