SQL & PL/SQL :: Finding Maximum Value Of Two Independent Columns Of Single Table
Jan 18, 2012The challenge I am currently facing is finding the maximum value of two independent columns of a single table. Here is the structure of the table:
[FiscalYear] [AccountingPeriod]
------------ ------------------
[2012] ------------- [2]
[2011] ------------- [12]
[2012] ------------- [1]
What I need to be able to do is to:
1) Determine the maximum value present in column FiscalYear, and then the maximum value available for this FiscalYear under the column Accounting Period.
I can do this fairly easy on Microsoft SQL server, but so far was not able to do this easily on Oracle database. My other observation is that using the MAX function on Oracle is very slow (even with thse fields being indexed). Is it possible to run this query on Oracle with only one pass through the table where the returned result will show 2012 for FiscalYear, and 2 for Accounting Period?

PL/SQL :: Merge Multiple Rows Into Single Row (but Multiple Columns)
Oct 17, 2012How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5
23 asdc 1 Location USA NM ABQ Four Seasons 87106
23 asdc 1 Stats 2300 91.7 8.2 85432

65 affc 2 Stats 5510 42.7 46 9999
65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country
Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population
Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:

View 5 Replies View RelatedSQL & 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?
Performance Tuning :: Update Columns Of One Table Using Another Table
Feb 6, 2011I am trying to update columns of Table A with the columns of Table B. Both these tables have 60,000 rows each. I tried this operation using following 2 queries:
Query 1
Update TableA A
set

from TableB
where A.CODE=B.CODE)
Query 2
Update TableA A
set
(A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3
from TableB
where A.CODE=B.CODE)
where exists
A.code = (select B.code

Loading Single Column Into Table?
Nov 16, 2012I am trying to load a single column into a Table. Below is the ctl file:
OPTIONS (ERRORS=10000)
LOAD DATA
TRUNCATE
INTO TABLE "ECOMM"."CC_ECOMM"
TRAILING NULLCOLS
(EMAIL_ID)
Calling loader:
sqlldr silent=ALL userid=username/password@DB control=/home/DEV/control/CC_ECOMM.CTL log=/home/DEV/log/Unsubs.log bad=/home/DEV/log/Unsubs.bad discard=/home/DEV/log/Unsubs.dis data=/home/DEV/files/CC_ECOMM.TXT
Though the count in the Table after load is the same as the input file, they are all NULL.
I tried adding FIELDS TERMINATED BY X'A' for new line and also FIELDS TERMINATED BY X'D' for carriage return. Both times bad file was created and the records that were loaded were again NULL.
The input file has a list of emails:
iatraveler2008@aol.com
iaz65@aol.com
2blue2brown@comcast.net
2c3mwilson@embarqmail.com
abigailolschan@comcast.net
imisskoco@aol.com
I tried FIELDS TERMINATED BY X'10' and FIELDS TERMINATED BY X'13' too for new line and carriage return respectively. This time there were no bad file created, but the Table has Null values.
Log File contents:
Number to load: ALL
Number to skip: 0
Errors allowed: 10000
Bind array: 64 rows, maximum of 256000 bytes
Continuation: none specified
Path used: Conventional

SQL & PL/SQL :: How To Create Single Table Cluster
Mar 6, 2010I have one table called posh, which has about 50,000 ids (millions of rows) so far. It is currently at about 50 gb. So each series of rows for a particular id is about 1 mb.
CREATE CLUSTER posh_cluster (id int)
SIZE 2M
STORAGE (initial 2000K next 2000K)
PARALLEL 4;
CREATE INDEX posh_cluster_index ON CLUSTER posh_cluster;
[code].......
According to the Oracle documentation size is "the average cluster key size", I am not really sure what that means. Is this the 1mb in posh table space I am using for each series of rows for an id, or the space used for the index? Secondly, the storage parameter for 'CREATE CLUSTER' should be what?

Single Table Hash Clusters
Mar 16, 2013I created a single table hash cluster like this :
create tablespace mssm datafile 'c:appmssm01.dbf' size 100m
segment space management manual;
create cluster hash_cluster_4k
( id number(2) )
size 8192 single table hash is id hashkeys 4 tablespace mssm;
-- Created a table in cluster with row size such that only one record fits one block and inserted 5 records each with a distinct key value
CREATE TABLE hash_cluster_tab_8k
( id number(2) ,
txt1 char(2000),
txt2 char(2000),
txt3 char(2000)
)
CLUSTER hash_cluster_8k( id );
[code]....
If I issue the same query after creating unique index on hash_cluster_tab(id), the execution plan shows hash access and single I/O (cr = 1).Does it mean that to have single I/o in a single table hash cluster, we have to create unique index? Won't it create additional overhead of maintaining an index?
What is the second I/O needed for in case unique index is absent?
