Grouping clause failing for CLOB Datatype

Hi,
I am facing error while Selecting the following expression:
ORA-00932: inconsistent datatypes: expected - got CLOB
OBJECT_CONTENT is a CLOB Datatype
SELECT
MAX(A.VERSION_ID)
OBJECT_CONTENT
FROM
VERSION_HISTORY A,
OBJECT_MASTER B
WHERE
A.BUOBJECT_ID=B.BUOBJECT_ID
GROUP BY OBJECT_CONTENT
Any help will be needful for rme

So, what's your question? You can use CLOB in the GROUP BY ....
quote from doc:
Restrictions on the GROUP BY Clause:
This clause is subject to the following restrictions:
You cannot specify LOB columns, nested tables, or varrays as part of expr.
The expressions can be of any form except scalar subquery expressions.
If the group_by_clause references any object type columns, then the query will not be parallelized.

What control i can use for Clob datatype in forms?

Hi,
Backend side
I had created a table that having a column namely sql_text which hold the query string and defined as CLOB data type.
On Form 6i
Just i created a textitem(long) for the clob datatype field
but it only hold very limited length of charter, i want to be more. Any other control is there?
please guid me what should i want to do.
kanish

There is limited support for CLOBs in Forms. I guess you could read it in piecemeal with a procedure using the DBMS_LOB package

A clob datatype and LogMiner question?

HI,
I am using Logminer to caputer all DMLs agaist rows with clob datatype, find a problem.
--log in as scott/tiger
conn scott/tiger
SQL> desc clobtest
Name Null? Type
SNO NUMBER
CLOBTYPE CLOB
--make a update
update clobtest set CLOBTYPE = 'Hello New York' where sno = 11;
commit;
after using LogMiner to analyze redo log files, to query.
select sql_redo from v$logmnr_contents where username = 'SCOTT';
update "SCOTT"."CLOBTEST" set "CLOBTYPE" = 'Hello New York' where and ROWID = 'AAD0ZqAAEAAAAhsAAC';
My quesion:
As to caputured DML
update "SCOTT"."CLOBTEST" set "CLOBTYPE" = 'Hello New York' where and ROWID = 'AAD0ZqAAEAAAAhsAAC';
it shows "where and", why there is missing after where clause????? --(anyway, I can overcome this by using REGEXP_REPLACE(sql_redo,'where and','where ')
Thanks

I checked logminer documetation:

it says 10GR2 support LOB datatype.
but why "where clause" omit the clob datatype column (becaume "where and rowid")????

SQLloder scripts not getting generated for CLOBs

I am trying to migrate MYSQL 3.23 database into Oracle 8.1.7 and after creating the Oracle model and after converting the MYSQL text datatype into CLOB of the Oracle model the SQLloader scripts is not getting generated for CLOB datatypes. I mean the scripts are getting created but there is no change in the script for CLOB datatype.
The script generates the following for the table containing CLOB datatypes:
mysqldump -h <HOST> -u <USERNAME> -p<PASSWORD> -T <DESTINATION_PATH> fields-terminated-by="<ec>" lines-terminated-by="<er>" test av_wbt_course
Please let me know how to load data when the datatype is of CLOB ?

I was able to resolve this issue by using OWM Oracle Migration instead of using offline method by sqlloader scripts.

Error in CLOB datatype for transfering data from Excel to Oracle database

Am using excel sheet as source and Oracle as target Database.
For all tables the operations works smoothly except for tables containing CLOB datatype.
Initially i have used SQL Developer to transfer some data into excell sheets, now i want to transfer those file's data into another Oracle Database.
What other options do i have?
Is excel not the right tool to transfer CLOB datatypes?

well,
I couldn't suggest an excel to do it...
You can go from Oracle to Oracle with the PL/SQL IKM. It works fine.
Does it help you?

CLOB Datatype (Assgin more than 32k fails)

Dear All
Can anyone tell me why i am getting this error if i assign more than 32k character to clob variable in pl/sql
but i can assign it from table to a variable
Pl/sql 1(ORA-06502: PL/SQL: numeric or value error: character string buffer too small)
declare
c clob;
v varchar(32767);
begin
for i in 1..90000 (just assuming it as 90k)
loop
v:=v||'x';
if length(v) > 31000 then
c:=c||v; -- here iam getting error while assigning character to clob if it is more than 32k
v:=null;
end if;
end loop;
c:=v;
end;
Pl/sql 2 (works fine when assgin from table)
declare
c clob;
begin
select clob_data into c from x; -- clob data is more than 32k;
end;
But it works fine with database 9i rel2 but in 11g i am facing this problem.
Regards

hey U r getting the error because of v varchar(32767) , but clob data type can take large amont of data atleast 1000000 this much data can be stored in clob data type try it with this. or else see below
Hi see the example below
create table temp(col clob);
declare
v_string clob;
begin
for i in 1..1000000
v_string:=v_string||'A';
end loop;
insert into temp values(v_string);
end;
now
select length(col) from temp; you will get output as
length(col)
1000000
this means that clob datatype can store minimum of 1000000 character.

Using CLOB datatypes in WHERE clause

Hi All,
I have a table with two columns as CLOB datatype. I'm using Oracle 8i Enterprise Edition. I can do a query, insert, update and even delete the data in the CLOB field using Oracle's SQL Plus.
What I want is to do a search on those fields.. that is include that field in a WHERE clause. I'm using this datatype to store large number of data.
I'd like to see this query working...
SELECT * FROM MyTable WHERE CLOBFLD LIKE 'Something...';
Now this query doesn't work. It returns: 'Inconsistent datatype' near the word CLOBFLD.
Please Help me out.
Regards,
Gopi
null

I presume you want to query based on the contents of the CLOB, right ? If that is true, then you have to create a text index, using Oracle Context and then use "Contains" in the where clause to query. Hope this helps.

Urgent Group by Having Clause Fails in Oracle and Works in Sybase

Hello EveryBody I need to select curve data of curve whose date is maximum in that curve so say if i ahve
so if records are
curveid curvename curvedate
1001 test1 12/12/1003
1001 test1 12/13/1003
1002 test2 12/12/2002
1002 test2 12/12/2004
I have query which run well in sybase but oracle screw up...My logic say having clause is use to filter the records of group so it should have worked in oracle.....
Here is query
select curveid,curvename from curve group by curveid having curvedate =max(curve_date)
This give "not a Group by " error in oracle....It work well in sybase...
ORA-00979: not a GROUP BY expression
I have query which use subquery to select these records but i don't want that to use that query
Please help

please understand what I need the result
for each curve i need that data of that curve who date is max in that curve group
so say for 1001 there are two date 1/1/2001 and 1/1/2002
I need the data of curve 1001 with date 1/1/2002
Oracle should have some alternative solution for this....
If i have to use subquery I do have subquery
select a.curveid, b.curvename from curve a group by curveid having curvedate = (select max(curvedate) from curve where a.curveid=b.curveid group by curveid );
I don't want to use that ,,,
I want to solve my probelm using having and group/....
Main purpose of having is to filter the records from group result so IT SHOULD DO THAT WHY ORACLE GIVE ORA ERROR FOR
group by curve_id having curve_date=max(curve_date)
Creators of oracle please reply

ORA-00313: open failed for members of log group 1 of thread 1

Hi
I'm restoring a database on a different host. I have the backups, from which I want to restore the database. I made the corresponding changes in the initSID.ora file and started the script to do the restore.These are the steps I followed:
connect target=/
run{
startup nomount;
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
allocate channel c4 type disk;
restore controlfile from '/tmp_backups/rman/lev0_open_cf_SID_2826_1';
alter database mount;
set newname for all datafiles
restore database;
set until logseq = 29317 thread = 1;
switch datafile all;
recover database;
alter database open resetlogs;
One mistake I made here is that logseq should have been last seq+1, which I did not do. I have it as last seq.
Restore of datafiles and switching of datafiles was fine. But I get error for redo log files.
ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: '/u13/oradata/SID/redo02a.log'

Additional information: 3
Why is it looking for at the old path yet?
I'm not sure what I missed and how to proceed. Please help.
Thanks,
Mamata

I do believe that set newname for all datafiles only means actual datafiles and no redo logs. So with open resetlogs, Oracle tries to create new redo logfiles where the backup controlfiles says they are.
As with creating a auxilliary database in another filesystem, we use DB_NAME_FILE_CONVERT and LOG_FILE_NAME_CONVERT.
I am not sure if it is possible to type "set newname for all datafiles" and expect also the redo logfiles to change location.
You might try to set these two parameters and see if it works.
good luck.

$ id

the problems seems relater to accessing /tmp
as the local disk is not enough to use the default /tmp (the DB install will fail with full disk error as the local disk space is very low )
I've created a partition from new disk to /tmp which I have then mounted (default is nfs3) :
# mount /dev/xvdc1 /tmp
# mount
/dev/xvdc1 on /tmp type ext2 (rw)
the result of DB install into /tmp is :
# cd /tmp
# ls -altr

if I umount /tmp but use the local /tmp
re-running the DB installer as user jjayet it does not raise the error above
and now local /tmp contains :
# cd /tmp
# ls -altr

do you know how to use tmp over nfs with user jjayet so that the DB can install properly ?
it seems that the files created as user jjayet into mounted /tmp are not identified properly
thks in advance
jean

thks for the pointer
I found the post you mention but it does not help
it does not explain the root cause of the problem but just propose a workaround to pass an option to installer which will popi\up an interactive messgae at install time
as installation is done automatically through ADE / DTE I cannot use this workaround
any expert in oracle DB install can help ?
thks

Hi,
Below note was taken from metalink;
Symptoms
Following errors in alert.log of standby database during startup of the standby database:
ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: '/u03/oradata/prod/redo01b.log'
ORA-27037: unable to obtain file status
Cause
Online Redo logs missing on standby database.
Solution
You can safely ignore these messages. Online redo logs will be created automatically when you activate the standby after switchover or failover.
If you want to fix these messages then please use following steps:
1. Check and set "log_file_name_convert" parameter if the location of log files are different on primary and standby.
SQL> alter system set log_file_name_convert = "'<location on primary>','<location on standby>'" scope=spfile;
If you are using pfile then set the parameter in init file after shutting down the database:
*.log_file_name_convert = '<location on primary>','<location on standby>'
For 10gR2 only : Set this parameter even if the location of the redo logs are same on both primary and standby otherwise you may get ORA-19527 and ORA-312 while or after implementing the below steps.
This is due to internal bug in 10.2.
2. Cancel Managed Recovery process on the standby:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
3. Execute the command to clear all log groups on standby for each log group (for each log group):
SQL>alter database clear logfile group 1;
4. Check the v$log view to confirm the size and status.
5. Recreate standby redo logs on standby (only if standby Redo logs are also missing) using:
(a) Drop the standby redo logfile group(s) (check v$standby_log)
SQL> alter database drop standby logfile group 4;
(b) Recreate the standby logfile group(s)
SQL> alter database add standby logfile group 4 ('/u03/redo/stby01.log') size 50m;
Hope it helps you.

ORA-00313: open failed for members of log group 2 of thread 1

We have a 4 node 32bit linux RAC (Dell/EMC) system running 9.2.0.4. It is very stable but over the past couple of months we've encountered a few ORA-00313 errors, while the system is running.
No patterns. Different loads, times of day, nodes.
The redo can't be opened, the node crashes, we look for errors, can't find any and then restart. The file is there and the permissions are fine. No other processes are accessing the files. No other Db errors. No O/S, SAN, Fiber, errors.
All the research I've done shows that this is an error you'd only get on startup.
We're going to log a TAR, but I can't believe we're the only ones to ever see this occur.
[directory and server names have been modified to protect the system. Don't get hung up on typos or possible file system config problems too much - this system has been and is running now]

The only thing I can still think of is file permissions.
If the system has recently been restored or Redo Log recreated, check the file permissions and ensure that Oracle has Read and Write Access to the Directory and Files.
At least the file permissions on the directory and files should look something like this example
$ls -l /sampledb/redo0/oradata/sampdb/
