SQL & PL/SQL :: Best Method To Populate Calendar Entries On A Table
Jun 2, 2011
I have a table :
Product
A
B
C
D
and I was wondering if there is a quick method of populating it with calendar data so it would look like the following:
Product Year Month
A 2008 Jan
A 2008 Feb
A 2008 Mar
A 2008 Apr
A 2008 May
A 2008 Jun
A 2008 Jul
A 2008 Aug
A 2008 Sep
A 2008 Oct
A 2008 Nov
A 2008 Dec
A 2009 Jan
A 2009 Feb
Etc.
This would be done for all products for 4 years.

I have a calendar region based on a simple query from a table which has date and name columns. The calendar type is monthly with 3 buttons - previous, today & next. It works perfectly.
I have added a date picker in a calendar region now. If i choose any date, the calendar month should be refreshed accordingly. Ie... by default it would show July 2012 month. When i choose the month as March 2012 in the date picker, it should show March month data.

I am abolute new in PL SQL and I am working on following topic:
I have to check if an entry exists in a table.
- if it exists ...... do something
- if not ...... simply go on
I tried the following:
select Count(*)from products p
where p.productNbr = temp_Nbr
Group By t.produkt;
I fetched the result into a variable entries
if entries > 0 .....
MY problem is the following:
If there are entries (entries>0) --> it works
If there are no entries, entries is not 0 but 'no data found' --> crash
I cannot work with Exceptions because this all happens in a Loop which must go on in both cases!

I'm trying to generate count of the number of entries in a table for each day.The problem is the date column is of datatype timestamp and looks like this "2006-12-30 18:42:03.0"
How would I generate a report of number of entries in the table for each date (I'm not intrested in the "time" only the "date" i.e YYYY-MM-DD)?
SELECT COUNT(*) FROM my_table_name
WHERE my_date_column LIKE '2006-12-30%'
GO
It returns zero rows ( and I kno there are rows in the table) I'm using Oracle 10g.

I use APEX 4.2.0. In Tabular form, I have column of Select list type. This list has too many values and the end user must choose all these values along the tabular form rows. In other words, If the LOV consists of X, Y , Z, The End user should add three rows and choose a unique value for each row.
The problem is : This LOV is supposed to have too many values. What comes to mind is:
1- Whenever the end user picks a value, this value should disappear from the LOV of the second row ? But I have no clue how to do it?
OR
2- Whenever the end use picks a value, I should notify him/her about the remaining values that he should pick . But I have no clue how to do it ?
At the end the purpose is to make the user aware that he still has some rows to add ( values to choose ... )
I simplified the issue in simple example here:
[URL]......
workspace: somefeto
user: test
pwd: test

I have a table like this
Desc Salesperson;
Emp_name varchar2(20),
emp_id number,
begin_date date,
end_date date,
is_current varchar2(3)
This is the first time the table is getting loaded. I get the distinct emp name from table 'X' and insert into teh sales person table to list out all teh emp present in the company and give the corresponding details.
I am not sure how to write a proc to populate the whole table. emp id is sequence generated.
begin date any date say 10/01/2010 (mm/dd/yyyy)
end date is 99/99/9999 indicating that the emp is not terminated
is_current flag = 'Y' if end date is 99/99/9999.
I have done a distinct empname from table 'X' and inserted into the salesperson table. Do i proceed to update the table for individual columns? *is that the right approach*?

Having trouble creating a trigger to populate another table.
The SQL:

BEGIN
INSERT INTO PAGE_MAKER VALUES(:NEW.D_NAME, :NEW.USER_ID);
END P_M_YES;
/
ALTER TRIGGER "P_M_YES" ENABLE

Which is the correct method to calculate actual data size in a table? becaue when I serach in google, I saw the below line.
"Oracle thumb rule says (actual space required for a table + 30 % space) will calculate the original space requirement for a table."
Method 1:
actual space = num_rows*avg_row_len
Method 2:
actual space = (Num of rows in a table) * (Avg_row_len) + ((Num of rows in a table) * (Avg_row_len)* 0.3)

I've a staging table STG_TABLEA which has a primary key discount_seq_no.
I am creating a pl/sql procedure to populate a primary key (discount_seq_no) with a database sequence. The intent is to keep this populated with next value incrementing by 1.
I am using Oracle 11.2.0.2 version.
I've put together the below code, not sure on next steps...
BEGIN
UPDATE STG_TABLEA
SET A.DISCOUNT_SEQ_NO = "INSERT A SEQUENCE HERE AND KEEP INCREMENTING the seq value by 1
COMMIT;
EXCEPTION

create table src(id number,val number,data varchar2(100)) insert into src values (1,1,'SUN');
insert into src values (2,2,'WED');
insert into src values (3,3,'MON');
create table trg(id number,val number,data varchar2(100)) required rows to be inserted in the target table.
insert into trg values (1,1,'SUNDAY');
insert into trg values (2,0,NULL);
insert into trg values (2,0,NULL);
insert into trg values (3,0,NULL);
insert into trg values (3,0,NULL);insert into trg values (3,0,NULL);
{code} based on the column value of the source table src's column val , i need to populate my target table trg . If the value of val is 1 then only one target row is created in the target .If the value of val in the source table src is 2 then the target is populated with 2 rows .The values of the target columns are mapped as follow:
1)id -as it is
2)val - if the val of src is 1 then map the val as it is .If the value of val is more than one then create as many rows as the value of val ,id will be as it is and the value of val and data will be null
3)data - if the val of src is 1 then expand the abbreviation else null .

12345 1/1/2000 Accounting Exp Unit
12345 2/1/2000 Acct. Expense Unit
12345 5/1/2000 Account Expense Unit
12345 10/1/2000 Account Exp Unit

DEPTID EFFDT ...DESCRIPTION BEGIN_DT END_DT
12345 1/1/1900 Accounting 1/1/1900 12/31/1999
12345 1/1/2000 Accounting Exp Unit 1/1/2000 1/31/2000

I would like to create a trigger on a table which populates a log table. In addition to using the table where the trigger will exist, I would like to populate a couple more fields in the log table with with data from 2 other tables.
e.g.
NAME_TABLE
-reg_id
-name
ADDRESS_TABLE *trigger to be fired when a new record is created here.
-reg_id
-srv_id
PROCESS_TABLE
-srv_id
-start_time
-end_time
This is what I would like the logging table to look like:
LOGGING_TABLE
-address_table_reg_id
-address_table.srv_id
-name_table.name
-process_table.start_time
-process_table.end_time
How can I go about creating this type of trigger?

Here is the log from sqlplus. When I select on RI field, it shows 2 rows. But when I select on SCNUM field, it shows only 1 row. This SCNUM has an unique index on it.
And it is still in VALID state

I've created a materialized view log on table with the following statement:
CREATE MATERIALIZED VIEW LOG ON table_a
WITH ROWID, SEQUENCE (column_a, column_b, column_c)
INCLUDING NEW VALUES;
The insert is done with the following statement:
INSERT
/*+ APPEND PARALLEL("table_a") */
INTO
"table_a"
("column_a",
"column_b",
"column_c",
"column_d_sum")
(select
column_a",
"column_b",
"column_c",
"column_d_sum"
from table_B)
But the Log is empty when the insert is finished. When I insert rows without the APPEND hint, rows are created in the log table. So, doesn't the log record bulk loads?

I have a table DN_ACTIONS with 9.5 million records. Column DA_OBJECT_NAME is not unique and same object name can have multiple entries. Column DA_ACTION_STATUS can have any values between 1 to 5.
I want to find all the DA_OBJECT_NAME in DN_ACTIONS where all of its entries has DA_ACTION_STATUS=3.
CREATE TABLE DN_ACTIONS
(
DA_ID NUMBER,
DA_OBJECT_NAME VARCHAR2(192 BYTE),
DA_ACTION_STATUS NUMBER(1)
);
best way as it does a self join on big table of 9.5 million.
(select distinct a.DA_OBJECT_NAME from DN_ACTIONS a where not exists ( select distinct DA_OBJECT_NAME from DN_ACTIONS b where a.DA_ OBJECT_NAME = b.DA_OBJECT_NAME and b.DA_ACTION_STATUS != 3))
What are the better ways to rewrite this query?

Tabular form works fine for first entries, but upon going back to add more records Page 55 has a button that links to the 'Approval' page which is a tabular form (Page 56).A text field at top of this tabular form receives the pass of a varchar2 field from page X which is an identifier (not PK). Tabular form query has condition WHERE ISO_NUMBER = :P56_ISO_NUMBER
When I add records on the first pass to the tabular form and click submit all is fine and dandy.When I get out of the tabular form and go back to it and add additional records I get this error:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "C4B43B9A17A41D287D55DEFE9B035944", item checksum = "607C07E22C9B03E6A45AF44EDC06BB31"., update "SPICE_HUNTER1"."DOC_APPRV_DOC" set "APPRV_DOC_ID" = :b1, "DOC_INFO_ID" = :b2, "ISO_NUMBER" = :b3, "DOC_APPROVER" = :b4, "DOC_APPROVED" = :b5, "DOC_APPROVAL_DT" = :b6, "DOC_COMMENT" = :b7, "APP_USER" = :b8Here's what I've done to try to figure it out:
1. Ran debug and saw it was happening in my MRU; and
2. In the past what I have cleaned out tabular form table data because I've found that when I'm in this testing mode going back and forth with changes gets fouled up, but with a clean slate it still happens.
3. I had Hidden the ID fields, and then remembered this was one of the issues with versions of this error. (I actually logged this one to remember!). So I made them Display as Text (Saves State) and unchecked their boxes.

We have a custom portal application that uses a bunch of application servers. Our connection pool max size is 1100. For the past two days, we had two incidents when the cpus reached the max limit and the db was not allowing connections to come thro' for 10 minute periods. The alert log does not have any entry and the listener log does not have any entry for that 10 minute period.

I am trying to ultimately as the title says separate a user input list into one column of entries. I am doing this through Cognos not a normal SQL editor which is what makes this a little harder to do. So far I have gotten that in general I can use the
SELECT 'First Entry' Asset FROM Dual Union
SELECT 'Second Entry' Asset FROM Dual Union
SELECT 'Third Entry' Asset FROM Dual
and this will give me 3 entries of data in one column. More can be added as long as the last statement doesn't have the union on it. So, the next step it would seem is to have a for loop combined with an if then or case statement that would find the number of entries and loop until we reach the number of entries and give me either SELECT 'First Entry' Asset FROM Dual Union or SELECT 'First Entry' Asset FROM Dual if we are on the last entry. I don't know the lingo to do this though. I have tried to get this to work with a simple test like cat, dog, horse, cow, pig, etc but it's frustrating that I can't get it to work. I can do all the individual steps I just can't seem to get it to work together. I have all the functions I need, I just need to the syntext to do a for loop along with an if then or case statement where the outcome is a valid select statement.

I have created a table: INDEX_SIZE_TRACKING with the following attributes
Index Name: name of the index. Type: VARCHAR(255). This is the primary key of the table.
Allocated Space: the memory space (in bytes) allocated to the index. Type: NUMBER
Used Space: the memory space used by the index. Type: NUMBER
Last Update: the time when index details are updated to this table. Type: VARCHAR(255)
I want to write a PL/SQL script to query index statistics data and update tracking entries in the INDEX_SIZE_TRACKING table. If there is no existing entry for the index, create a new one; otherwise, update the existing one. have a PL/SQL statement that can do this in oracle XE?
