update the indexed column
I got a name emp table that holds at least 30000 lines and I had created an index on emp_city
What happens if I update a value of emp_city? What effect will create it on the index or table?
the index will be updated automatically?
the index become invalid?
the line in the journal in the index will be deleted and inserted?
or updated in the journal will take place?
According to the name of the field, I understand that the distribution is pretty sparse for normal index on emp_city.
Will be better to create a bitmap index where you apply to this table with OLAP queries or not create an index on this field.
I don't care
If you have an index on emp_city or emp_city is a part of some regular index and you will upadate all value emp_city:
the index will be automatically updated. (Yes)
the index become invalid? (No, but I suggest that you run statistics on index or table wole)
the line in the journal in the index will be deleted and inserted? or updated in the journal will take place?
It's block of sheets (not rank of petals). Entire block will be replaced.
Best,

Identify the weekend and the days of the week a date and update the empty column
Hi, I look at previous posts that are similar to my question, but nothing helps.
I have a column called incident_date that is in this format and comes from the Nov_Final table
In Nov_Final, I created a column called weekend01-JUL-2009 20.10 04-NOV-2009 17.00 16-DEC-2009 16.00
What I want to do is to perform an update, something like this:

Weekend would be Saturday or Sunday. In short I need to find out if the incident_date falls on a weekend and if it does update the weekend column as 'Y' else 'N' if it's not.
You can use TO_CHAR function with a format mask as "fmDAY" to your needs:

Classic generic column report - update the list column
Consider a dynamic pivot statement as follows (as described by the AMIS) which
select * from table( pivot( 'select deptno, job, count(*) c from scott.emp group by deptno,job' ) )
I used this as a SQL source for the classic report, by selecting "use generic column names.
The report looks like
I can set up the data displayed with a selection list and including a clause where clause
where job =v(''P39_JOB'') or v(''P39_JOB'') is null
List select not PPR on the region,demonstrated here:
https://Apex.Oracle.com/pls/Apex/f?p=73000:39:
Note: , and all swivel jobs are still visible in the form of columns, data is limited
-other jobs are empty
-departments with no clerks are not shown
Let's say you have another list of selection than the work of groups, say the "Présidents" and "close".
How can you update the region to exclude certain jobs?
Reload the page with the value of P39_JOB already set will not affect the result, while including a literal string made.
It seems maybe ODCI function analyzes the query on Lees null, and then fills with actual results.
Does anyone have any suggestions?
Update: it seems a workaround is to inject the value as a substitution string, for example:
and employment as ' & P39_CEO. »
where P39_CEO is lacking in session state %
I've only had this concept works in my client application (4.2, 11 2 GR), not my demo (5.0, 12 c), to even try to meet the relevant quotes and when null. I kept getting
error report: ORA-1403: no data found

Hi Scott
What approach I described in this post: matrix report?
It eliminates the need for any dynamic SQL and I think filtering options might be implemented using SQL/XML features.

Hi all
I'm looking for some API which will help me to update the columns attribute on the lines of PO. I searched in metalink also but I have not found any idea for that.

Ravi Raj.API in general do not update or manipulate ATTRIBUTE columns from these customer data defined in the store. You will need to update these columns directly.

I created a new table and inserted the number of lines (for example near 1000), the index database is updated to take into account (or view) the newly inserted rows. How to find the time to update the taken by the index of prior State to a new State, referring to the newly inserted rows of 1000?
You can try to use the runstats tool to compare 2 different scenarios SQL and deduct the time required for maintenance of indexes.
Scenario1:
Insert 1000 rows in a table without indexes on the tablescenario2:
Insert 1000 rows in the table with the index on the tabletime for scenario2 - time for scenario1 is time for index maintenance, provided that you run these tests on hosts/databases without concurrent activity.

Cannot insert or update the password column
For the site that I am building, I have problems with the Member to add, change, and change password pages. I determined that the problem lies in the insert or update the password for the database column. If I remove the field of password in both add and edit pages members, they work very well (in doing so, to change the password page would go on to defeat its purpose, so have not tried it). I have Dream Weaver 8 allows to design and was wondering if there is something in the log in user and restrict access (user, password and level) it is tool that creates some how would lock the column preventing the modification of the server behaviors. Can someone help me with this you problem?It's probably a reserved word, try to escape the domain name with brackets
(for example [password]), or rename it.

update the column of type char to stem after insert or update the same column
I have the table "people":
DESC PEOPLE
Name Null? Type
------------------------------- -------- ------------
ID NOT NULL NUMBER
NAME VARCHAR2 (25) NOT NULL
and I need to make sure that the NAME column is always in uppercase letters, so I did as he illustrated in this link:
http://asktom.Oracle.com/tkyte/mutate/
I did this: -.
==================================
CREATE OR REPLACE TRIGGER parent_bi

BEGIN
state_pkg.newrows: = state_pkg.empty;

-----------------------------------------------------------------
CREATE OR REPLACE TRIGGER parent_aifer

NAME = UPPER (NAME)
People WHERE. ROWID = state_pkg.newrows (i);
END LOOP;
END;

======================================
but nothing is coming, as the same that these triggers do not exist.
So, what is wrong?
and how I workaround to make this statement:-
Setting a DAY people SET NAME = UPPER (NAME);
whenever I update or insert in the name column.It is much simpler that that - you just need a BEFORE INSERT trigger
CREATE OR REPLACE TRIGGER your_trigger_name BEFORE INSERT OR UPDATE ON persons FOR EACH ROW BEGIN :new.name := UPPER( :new.name); END; /
As you can see from this example, which will force all uppercase
SQL> create table persons ( 2 name varchar2(10) 3 ); Table created. SQL> CREATE OR REPLACE TRIGGER your_trigger_name 2 BEFORE INSERT OR UPDATE ON persons 3 FOR EACH ROW 4 BEGIN 5 :new.name := UPPER( :new.name); 6 END; 7 / Trigger created. SQL> insert into persons values( 'justin' ); 1 row created. SQL> insert into persons select lower(ename) from emp; 14 rows created. SQL> select * from persons; NAME ---------- JUSTIN SMITH ALLEN WARD JONES MARTIN BLAKE CLARK SCOTT KING TURNER ADAMS JAMES FORD MILLER 15 rows selected.
Also, you generally want to add a check constraint to ensure that NAME = UPPER (NAME).

Update the same column in the same table

I have purchase_order of the table. Consists of column ID, color, Purchase_No, Sub purchase.

Create table Purchase_Order)
Identification number,

purchase_No varchar2 (5).
purchase_sub varchar2 (2));

ID color Purchase_No purchase Sub
6416 S1406 PURPLE 3

6414 S1406 GREEN 1
6419 S1406 3
6417 S1406 1
6418 S1406 2
< pre >
6 unique ID records is in the same site. But 2 ID will be confined to a purchase_sub.
For example
6416,6419 purchase_no S1406 but has the same purchase_sub who need 3.I 6419 color "Purple".
Expected results:
< pre >
ID color Purchase_No purchase Sub
6416 S1406 PURPLE 3
6415 S1406 GREEN 2
6414 S1406 GREEN 1

update of NULL in the column with the values of the adjacent column
Examples of data
with test_data as (select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual union all select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual) select * from test_data;
This is one of those cases, the case may be where any value of a column can be null
or two similar columns can be null. If the column is null then I want to update the adjacent column
average value of the column, if the first column is null so I want to take the next non-null column and update, if the last column is null
so I want to take prev not zero column and to update.
In this case would be my expected output
