Server Utilities :: Creating SQL Loader Ctl File With Over 1000 Columns?
Dec 3, 2010Next week I will be getting an input file which will contain over 1000 data columns to be loaded into ORACLE. It's about 6,400 characters in length.
My question is...has ever created a huge ctl file like this to be used for SQLLoader, using so many columns? I will be sending certain columns(data) to certain tables, so it's not just going into 1. It will be about 6 tables.

View 4 Replies View RelatedSQL & PL/SQL :: Can't Exceed 1000 Expressions In Query
Nov 18, 2011I am trying to run the following query below in Oracle:
Select Acct_Num, Customer_Name
From Database
Where Acct_Num IN (
1,
4,
104
..,
..,
192384,
200002
)
When I attempt to run the query, I get the error message: "ORA-01795 maximum number of expressions in a list is 1000"
Is there any way I can execute this query w/o having to break the 'IN' list up by 1,000 Acct_Num over numerous amount of times? I know the 50,000+ accounts I want the info on but they are not ordered and they mix ranges with accounts I don't want. Therefore I can't use a 'BETWEEN' clause. Also, I don't have the ability to create a temp table.
SQL & PL/SQL :: BULK COLLECT And Employ LIMIT Of 1000 With FORALL
Oct 19, 2011I have an app that reads records from a driver table in order to update another (account) table. The idea is that it runs quickly but does not impact other processes on the system. In total I have around 1M records to update.
Originally I wanted to BULK COLLECT and employ a LIMIT of 1000 with a FORALL. The problem with this approach though is that I make two updates. One to the target table but I also need to update the driver table showing that I have processed the record. Therefore I cannot use this option to commit every time I reach the LIMIT by having a COMMIT inside the LOOP.
So instead I I have a FOR LOOP and test the count, if it is 1000 then I want to commit. I thought this syntax would be fine but I get the 'Fetch Out of Sequence' error. Below is a copy of the code.. Is this being caused by the double update... as the format of the code looks correct to me (though it is late!!)?
PROCEDURE update_set IS
CURSOR cur_get_recs IS
SELECT account_num,
ttw_active_flag,
acct_rowid,
rowid driver_rowid
FROM driver_table
FOR UPDATE OF processed;

SQL & PL/SQL :: How To Commit After 1000 Records In Simple Insert Statement
Oct 10, 2011I am using Oracle 11g Release 11.2.0.1.0
OS: windows
I am taking an example of EMP table in a scott schema.
EMP_1 is also a same structure of EMP.
Here is the Insert statement used.(i might get where clauses etc in the real scenario i am taking a simple example here)
INSERT INTO SCOTT.EMP_1(JOB,ENAME,EMPNO) SELECT JOB,ENAME,EMPNO FROM SCOTT.EMP
table EMP is having around 25 million records.
i would like to do a commit after every 1000 records. as my redo log is getting full if i use a single commit at the end.
Quote:pls note: Increasing of redo log is not possible as of now
is there anyway i can acheive this without cursor bulk collect.

SQL & PL/SQL :: Create Complete Hierarchical Table From Table With Only Two Columns - Parent And Child
Aug 13, 2012We have a table in the client database that has two columns - column parent and column child. The whole hierarchy of DB table dependencies is held in this table.If Report 1 is dependent on Table A and Table A in turn is dependent on two tables Table M and Table N. Table N is dependent on table Z it will appear in the db table as,
Hierarchy Table
Parent Child
Report1Table A
Table ATable M
Table ATable N
Table NTable Z
Requirement :
From the above structure, we need to build a table which will hold the complete hierarchy by breaking it into multiple columns.The o/p should look like this
-ParentChild 1Child 2 Child 3
-Report1Table ATable M
-Report1Table ATable N Table Z
Child 1, Child 2, Child 3 ....and so on are columns.The number of tables and the no of hierarchical relationships are dynamic.
SQL Statements to create hierarchy table:
create table hierarchy (parent varchar2(20), child varchar2(20));
insert into hierarchy values ('Report1','Table A');
insert into hierarchy values ('Report1','Table B');
insert into hierarchy values ('Table A','Table M');
insert into hierarchy values ('Table B','Table N');
insert into hierarchy values ('Report2','Table P');
insert into hierarchy values ('Table M','Table X');
insert into hierarchy values ('Table N','Table Y');
insert into hierarchy values ('Report X','Table Z');
Approached already tried :
1) Using indentation : select lpad(' ',20*(level-1)) || to_char(child) P from hierarchy connect_by start with parent='Report1' connect by prior child=parent;
2)Using connect by path function :
select *
from (select parent,child,level,connect_by_isleaf as leaf, sys_connect_by_path(child,'/') as path
from hierarchy start with parent='Report1'
connect by prior child =parent) a where Leaf not in (0);
Both the approaches give the information but the hierarchy data appears in a single column.Ideally we would like data at each level to appear in a different column.

Truncate / Drop Partitions In Table Having Nested Table Columns
Sep 7, 2012I have a table that has 2 columns of type nested table. Now in the purge process, when I try to truncate or drop a partition from this table, I get error that I can't do this (because table has nested tables). how I will be able to truncate/drop partition from this table? IF I change column types from nested table to varray type, will it work?
Also, is there any short method of moving existing data from a nested table column to a varray column (having same fields as nested table)?
All Columns Of A Table Are Part Of Primary Key Column Of That Table?
Feb 22, 2011if a table contains two columns and both are part of the primary key of that table (Kind of obvoius).
should i opt for a index organized tbale in this case ?Or should i opt for another running sequential colum which would serve as a primary key of this table and define the actual two columns of the system as unique keys.
there is a drawback if a most of the tables of a database contain composite primary keys?

from TableB
where A.CODE=B.CODE)
Query 2

Append Columns From One Table To Another
Nov 14, 2011Perhaps this is a common request : I have 2 tables:
Table A
-------
ID Value
1 a
2 b
3 c
Table B
-------
ID AnotherValue
1 x
2 y
I am hoping to append a column from Table B to Table A based on a simple sql join (e.g:
Table A
ID Value AnotherValue
1 a x
2 b y
3 c (null)
)
I would rather stay away from the standard update statement since it takes far to long and I'd prefer not to use create table as I don't want to duplicate any data...is this possible to do ? (e.g: just insert the columns into this table ?) - or if it's possible the performance overhead just wouldn't make it worth it ?
Joining Two Columns In Same Table?
Jan 30, 2007We have a table for reports. If user A submits a report ...and say the sequence # is 242. When this report goes to Admin ...he submits this request then in same table we add another row with say sequence # 245. THEN we update column called 'Asctd ID' for 242 and add 245 in there. and then update Asctd ID for 245 and add 242 in there.
(This table has many fields, one of which is report Name field)
Now i am running a query like this...
SELECT b.JOB_ID, a.DESC, TO_CHAR(a.CREATE_DATE,'MM/DD/YYYY'),
DECODE(a.DLVRY_TYPE,'','PDF',a.DLVRY_TYPE), DECODE(a.FLG,'','N/A',
a.FLG), ((TO_DATE(a.CREATE_DATE,'DD-MON-YY')) + 21) -
TO_DATE(SYSDATE, 'DD-MON-YY'), c.STATUS_DESC, a.SIZE_NUM,
b.PRVDR_ID, a.asctd_id, d.NM
FROM REQUEST_DIM a, PROVIDER_DIM b, STATUS_DIM c, DIM d
WHERE a.FLAG = 'P' and RTRIM(a.RPT_RQST_USER_ID) = 'TEST02' AND a.RPT_RQST_TYPE = 'D'
AND a.RPT_RQST_ACTIVE_IND = 'A' and a.asctd_id is not null and a.RPT_RQST_ID = b.RPT_RQST_ID
and b.JOB_ID = c.JOB_ID and b.PRVDR_ID = d.PRVDR_ID
AND c.CREATE_DT = (SELECT MAX(d.CREATE_DT)
FROM STATUS_DIM d
WHERE d.RPT_RQST_ID = b.RPT_RQST_ID and d.JOB_ID = b.JOB_ID )
ORDER BY a.RPT_RQST_ID, a.CREATE_DATE
Now this query is run by the admin (job 245) ...it returns a bunch of stuff and also the name of the report that the admin gave this. But when admin sees this we want to be able to displace the report name that user A gave it (asctd ID 242). so the row 245 HAS a asctd ID 242. and there is a row 242 from which we can get the name easily. But i dont know if this is possible in ONE QUERY??
Search All Columns In A Table
Jan 15, 2009I have an application which deploys the data to Oracle database. It has more than 25 tables and many columns. It does not have any document explaining the deployment, so I am kind of doing reverse engineering here.
I need a script which will fetch the column name or at least table names which will match with either some string or number? I found few examples on net to find out number. But I am struggling to make it work for string.
I can not work on stored proc, as I do not have access to create that on server. So, any script will work.

View 3 Replies View RelatedPartition The Same Table Using Different Columns
Mar 5, 2013I’m facing an issue in my current project where we have to run batch jobs and interfaces on the same master tables. These tables are huge (millions) and we get very poor response time.
We thought of partitioning the tables, but the problem is our batch jobs queries are based on dates (some run on monthly data, some runs on yearly data..) but interfaces uses primary keys.
I’m not sure on how to partition the tables in this situation, is there any way I can partition the tables in such a way that both batches and interfaces will get benefit out of it?
Our database infrastructure has a 3 Node RAC (each with 8 CPUs) and oracle 10g R2. We have almost 60gig of RAM allocated to oracle.
PS: We are not thinking about Mviews now because client wants to explore the partition option first.
