SQL & PL/SQL :: REGEXP_SUBSTR / Executing Prepare Statement
Jan 26, 2011
I am using embedded sql in a Fortran program on IBM AIX. Whenever I execute a SQL statement other than connect I get a coredump. So I wrote a small test program, but same thing happens. This is the test program -
PROGRAM TEST
EXEC BEGIN DECLARE SECTION
CHARACTER*20 UDPWD
EXEC END DECLARE SECTION
[code]....
And then when I run test, I see the 'Connected' print & then coredump. Same thing happens for EXEC SQL Prepare statement. Am I not linking some library ?

refer following sql statements and code
Session 1
create table tab1 as select * from dba_objects where object_id is not null;
alter session set events '10046 trace name context forever, level 12';
declare
x number;
begin
for i in 1..4
loop
[code]....
Session 2
after "starting" the above pl/sql block from Session 1, I keep on querying tab2 from Session 2 And as soon as 2 records are inserted in tab2, I create index from Session 2
select * from tab2;
select * from tab2;
select * from tab2;
N
----------
1
2
create index i on tab1(object_id);
As I have tested from a single session (just before this test) such index is used for the sql statement
select count(1) into x from tab1 where object_id=2331;
However when I checked the trace file I am not geeting results as expected
I am expecting 4 execution plans - 2 FTS and 2 Index Access scans and for this I am issuing following command
tkprof dst1_ora_7369.trc dst1_ora_7369.txt aggregate=no sys=no
But unfortunately I am getting following output
SELECT COUNT(1)
FROM
TAB1 WHERE OBJECT_ID=2331
call count cpu elapsed disk query current rows
------- ------ -------- ---------- ---------- ---------- ---------- ----------
Parse 1 0.00 0.00 0 1 0 0
Execute 4 0.00 0.00 0 2 0 0
[code]....
1) Why I am unable to see 4 execution plans - 2 with FTS and 2 with Index access when I mentioned 'aggregate=no'?
2) Whether the index i will be used for last 2 iterations after first 2 iterations of FTS?
If answer to above question 2) is 'No'
By which method I can force an ongoing sql statement in loop to take different execution path? Of course I can't hard parse sql in 'that' current session Will flushing Shared pool work in above case?

I need tablespace name,tablespace total size and used size of every tablespace for my 106 databases. bcz I am planning to prepare tablespace growth report for my 106 dbs. If I have the 2 months data from now in xl sheet, then I can predict the growth rate of every tablespace accurate almost.
it is not a easy task to fill the space detail manually in xl sheet everyday.Hence I need some mechanism to do this activity automatically.
I know we can collect this detail in a csv file every day while running the script. but is there any mechanism to store these detail in a particular xl sheet one by one column automatically?

I got a record in the column:
<li class='tbl-b'>Ram card: Yes, typ: MicroSD, max. 16 GB </li>
And I would like to extract just:
Ram card: Yes, typ: MicroSD, max. 16 GB
Without <li class='tbl-b'> and </li>.
I try to do this by REGEXP_SUBSTR but not successfully.

My Database is in Oracle 11g.
My query returns the 3rd field from a CSV string. If the third field in the string is empty I want the select to return a null but it returns the 4th field :
SELECT REGEXP_SUBSTR( 'A,B,,D,E','[^,]+',1,3) from dual;
.. this returns 'D'.
Can we somehow make the REGEX_SUBSTR return a NULL for the third field ?

I'm trying to get this down from two regexp to a single one, but I'm not sure it can be done and if so, its beyond me to work out how atm.

The expression itself contains all the rules I'm aware of (nothing to say they won't move the goalposts again mind!) of and the desired output is as shown above. I should add that the actual data is more complex (many tags per record) so it rules out a regexp_replace

I can separate numbers from string (info) and the first value of the string using REGEXP_SUBSTR (see below):
with dat as (select '35263304 Alcatel One Touch 806' info from dual)
select info, REGEXP_SUBSTR ( info, '[[:digit:]]+',1 ) tac,
REGEXP_SUBSTR ( info, '[[:alpha:]]+',1) brand
from dat
But how can I get rest of the values from that string (red color) ?
I just would like to get separately like:
35263304 Alcatel One Touch 806

I'm trying to query an array where we will have mathnames that have the follow format: variablemathname[00000]
have been digging around for a few days to try and simplify my existing query. As of right now i'm hacking it together to bring back the bracketed array value by using INSTR and SUBSTR. This works and gets me the correct results but I want to clean the code up by using regexp_SUBSTR.
In my reading up on regular expression I've tried to create my pattern by using [.] which I believe to be [any character]. I want it to start at the beginning of the string so I've used [^ and I only want the one occurrence so I've ended my expression with ]
I tried using the escape before my pattern as I know that [ is a metacharacter but I receive the same results.i'm trying to use to get the expression correct.
SELECT REGEXP_SUBSTR('variablemathname[00000]', '[.],[^,],') RESULT
FROM DUAL;
My expectation is it will bring back the following [00000] but the way it is written now is bringing back nothing.

I am using regexp_substr to break the pipe delimited string. Want to use the output as the NUMBER input to a cursor.Its not working and not getting any error also.
Here is an example.
initial input : '5545|4124|12456'
using the sql below to break the string into columns.
select regexp_substr('5545|4124|12456','[^|]+', 1, level)) from dual
connect by regexp_substr(, '[^|]+', 1, level) is not null;
But when i try to pass the output of the above query to a cursor with input defined as number, its not accepting. I tried using to_number for the output of above query.

I don't know how to control if a call to a PL function return errors.
I have this ksh:
executeFunction () {
echo "[executeFunction ]-> Phoebus DB started"
sqlplus -s /nolog <<!EOF!
CONNECT $USER/$PWD@$DB
@/sql/ejecutaFuncion.sql
EXIT;
!EOF!
}
executeFunction
And the code of "ejecutaFuncion.sql" is:
executeusers.startProcessing();
EXIT
How i can controle if the "startProcessing" function has any problems from the ksh?

I'm trying to execute a procedure within a Declare/Begin/End statement and using variables as input parameters in my procedure but I keep on getting an Invalid SQL Statement Error. My code is below:
declare
START_dt VARCHAR2(30);
END_DT VARCHAR2(30);
begin
SELECT '01-APR-2011'
INTO END_DT
FROM DUAL;
[code]....
The table the procedure is pulling data from doesn't have proper date/time stamps but my procedure takes the varchar dates above and turns them into dates in the procedure so the input date parameters are left as just string characters.

Database 1(sm01):
=============
oracle, 9.2.0.6
there are 4 jobs scheduled in oracle dbms_job. 3 jobs will run everyday at 4.00AM. 1 job will run at every hour.Daily jobs are running fine. But hourly job is not executing automatically. If forced (exec dbms_job.run(<enter here job number>), this execute fine.
job_queue_processes=5
total jobs in schema=2503
total jobs in db = 2614
Even there are many jobs scheduled, next_date for 2234 jobs are lesser than the sysdate. Again in 269(2503-2234) jobs, 2265 are having NULL in the interval column.
Database 2(sm02):
=============
oracle, 9.2.0.6
there are 4 jobs scheduled in oracle dbms_job. 3 jobs will run everyday at 4.00AM. 1 job will run at every hour.All the jobs are not running automatically. If forced (exec dbms_job.run(<enter here job number>), these execute fine.
job_queue_processes=5
total jobs in schema=7
total jobs in db = 7
I planning to follow the below steps to avoid the above issue.
1.) Restart the job queue process by executing alter system set job_queue_processes=0
2.) Increase the value for the job_queue_processes.
3.) Restart the database
But I got stuck in the 2nd step. what value I need to put for this job_queue_processes parameter?
