New Tables And Indexes Created Not Show In Dba-segments View?
Aug 8, 2012I have created 3 tables and some indexes, but these objects do not show up in dba_segments view. Is this a normal behaviour? Previously, with dictionary managed tablespace, I can specify the minimum extent to create, when the table/index is created. But I'm not sure how the locally managed tablespace work.
I'm using Oracle 11g R2 (11.2.0.1.0) for Microsoft Windows (x64), running on Windows 7.For the purpose of reproducing this issue, I have created the tablespaces as follow:
CREATE TABLESPACE CUST_DATA
DATAFILE 'd:appasusoradataorcl11gr2CUST_DATA01.DBF' SIZE 512K
AUTOEXTEND ON NEXT 256K MAXSIZE 2000K
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K

Apr 8, 2012I'm stuck on the CREATE VIEW part and the SELECT statement to get the output of the CREATE VIEW. We were instructed not to use AND and simply use JOIN on this exercise.

Trigger When View Created?
Aug 24, 2011I want to create a meta data table which has all the views users can access with a description of what the view was supposed to do.
Is there a trigger that can be created that fires when a view is created? To make it easy only one user in this system (oracle 9.2.0.8) has the create view privilege.
I know I could write a procedure to create views with dynamic sql that would do this but that seems a bit of overkill.
the sequence of events should go like this:
view created
trigger fires
record with view name and creation date inserted in a table
later, manually go to the table and add explanatory comment
or can I add a comment to a view like you can to tables?

Performance Tuning :: Index Has Been Created On Both Depart_id For Two Tables
Jul 30, 2010SELECT department_id
FROM (SELECT department_id
FROM employees
UNION
SELECT department_id
FROM employees_old )
WHERE department_id=100;
[code]....
The index has been created on both depart_id for the two tables. The only difference between the two I observed was the 1 recursive call for the 1st sql.and also, one additional view in the plan.There is a little difference in bytes sent over the network.
Statistics
----------------------------------------------------------
0 recursive calls
0 db block gets
6 consistent gets
0 physical reads
0 redo size
[code]....
Is there any performance impact you find in those above two sqls if you compare?
Server Utilities :: Load 780 CSV Files Into 12 Tables Created In Database - Sql Loader?

sqlldr abc@tns/pwd control='E:htmlctlhtml_broken_jobs_rpt.ctl' log='E:htmlreportloghtml_broken_jobs_rpt.log'

we know creating 780 control files is the difficult task.So I have created only 12 control files. is there any mechanism to pass a varible (planning to declare it in the sqlldr line) to the infile clause like below in sql loader?
infile "E:htmlreportoutput&a_html_broken_jobs_rpt.csv"
here a is the variable name. it will change every 12 csv files once.

SQL & PL/SQL :: Multiple Row View From Splitting Table?

where in the data's are as follows
chitta_enn varavu_patti pattru_patti Thogai
101 panam null 101.00
101 null sambalam 51.00
101 null kamishan 50.00
I need to create the view as follows
View Name : Pattiyal
vivaram varchar2(2000)
varavu number(10,2)
pattru number(10,2)
The view data should get display as follows
vivaram varavu pattru
sambalam kamishan null 101.00
panam kamishan 51.00 null
panam sambalam 50.00 null
Logic:
Each table row will have only one value either in varavu_patti or in pattru_patti. On selecting the row, thogai must be posted in varavu when varavu_patti is not null or should be posted in pattru when pattru_patti is not posted.on selecting the table row, vivaram should contain all other rows varavu_patti and pattru_patti on equating chitta_enn
Is it possible to create a view as above

SQL & PL/SQL :: How To Sum Over Multiple Tables
Feb 21, 2010I'm trying to do a sum over 2 different tables but can't get it to work...This is the idea:I have a table A with client ID, time-id (per day), purchase amount and segment code.
In another table (let call it B) I have a lot of client ID's and also their purchase amount, time-id and segment code. I want to sum the purchase amount for every client from table A and B for clients with certain segment code from table B.
This is what I have now:
select client_id, purchase_amountA+ purchase_amountB from tableA, tableB where
A.client_id = B.client_id
and time_id between 20090101 and 20091001
and B.segment_code = 'A'
This does the job, but it selects only client_id's which are in both tables. I want to select all client_id from table B with segment_code 'A' and add the purchase_amount from table A to their purchase amount from table B, at least, if they have any purchase amount in table A.

SQL & PL/SQL :: How To Create A View Having All Rows From Tables
Apr 21, 2010I have a table as shown below,
SQL> select * from Main_Table;
AA
--------------------
SUB1
SUB2
Here the SUB1 and SUB2 are "tables" and are similar in their structure. The "Main_Table" will be update dynamically and the no of rows in this table will vary.
Now my question , i need to create a view which will have all the rows from these tables ,in the current case it is something like
create or replace view sample
as
select * from SUB1 union all
select * from SUB2
How can this be achived. I tried as shown below:
spool file_to_exe.sql
select 'select * from ' || AA ||' union all ' from Main_table;
spool off
i will end up in a union all "extra" , if i do like this.
how can achieve this ?..
SQL & PL/SQL :: Store Data From Multiple Places In Materialized View?
Apr 14, 2011I have a PL/SQL procedure which gathers data from multiple places as well as calculates some data. I want to store all this in a materialized view.So, I created an object type (I've shortened the definitions):
CREATE OR REPLACE TYPE mf_record_type AS OBJECT
(identifier VARCHAR2(6),
name VARCHAR2(100));
Then created the table type of the object:
CREATE OR REPLACE TYPE mf_table_type IS TABLE OF mf_record_type;
Then in the stored procedure defined a variable of the table type:
v_mf_record mf_table_type := mf_table_type();
Then I loop and populate the record type:
v_mf_record.EXTEND(1);
v_mf_record(x) := mf_record_type(v_rec.identifier, v_mf_detail.name);
When all that is done I try and create the materialized view:
EXECUTE IMMEDIATE ('CREATE MATERIALIZED VIEW mf_snapshot_mv AS
SELECT * FROM TABLE (CAST (v_mf_record AS mf_table_type))');
ORA-00904: "V_MF_RECORD": invalid identifier
Am I doing something wrong here? Can't I create the materialized view based on something other than a physical table?

SQL & PL/SQL :: Get Sum Amounts From Multiple Tables?
Mar 2, 2011I have a primary table and some secondary tables. I need to use the key from Primary table and get the sum/totals from the other tables with a single query.
For example, I have 3 tables employee, employeesal and employeerewards in which employee is the primary table. I need to get the total salary for an employee from employeesal table and total rewards from the employeerewards table using one query.
I am pasting the test data below:
create table employee (eno number(9), ename varchar2(40));
insert into employee values(1,'Jack');
insert into employee values(2,'Jim');
[Code]....
I am looking for a better way of doing this in terms of performance. In my projecct, those 3 tables are very big tables and I doubt if I do two inner queries and then use a outer query may not be the best way to do it.
Is there any better way to write this query in terms of performance?
SQL & PL/SQL :: JOIN For Multiple Tables
Mar 29, 2011Here is what I'm trying to do:
I have three tables:
TABLE1 TABLE2 TABLE3
NCI 1AB OPEN
NCI (NULL) (NULL)
INV (NULL) (NULL)
NCI 2AB REOPEN
What I want to do is to return all of the rows from TABLE1 that are NCI regardless, and if they are NCI, I want to return the corresponding records from TABLE2 and TABLE3.
If TABLE1 has a record of NCI but there are no corresponding records in TABLE2 or TABLE3, then of course the columns for TABLE2 and 3 would be blank.
I can get all of the NCI records from TABLE1 when I LEFT JOIN with TABLE2, but when I try to specify TABLE3 in the FROM statement, only the records that are NCI in TABLE1 AND have data in TABLE2 are returned, not just all records with NCI in TABLE1.
Let me know if I can further clarify.
I know that you do not have access to my tables, but here is an example of my code so that you may understand my quandary further:
SELECT l.sku AS "SKU",
l.loc AS "LOC",
l.qty AS "QTY",
o.ncikey AS "NCI",
r.description AS "NCI DESC",
o.qtyexpected AS "NCI QTY EXP",
o.qtyreceived AS "NCI QTY REC",
o.loc AS "NCI LOC",
o.status
