Query Table Entries With A (timestamps) Column?
Jan 11, 2007
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 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?

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?

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 have one table which has 90 columns all has varchar2 datatype except one Column[primary key (Number)]. In this Table we have 1000 records, I want to fetch those records from Table which has value in all 90 columns means there is no null value in any column.
I know simple method Like this :-
column_name1 IS NOT NULL AND Column_name2 IS NOT NULL.
Like this we can write IS NOT NULL condition for all column.Is there any other way to write this Query because it makes Query very longer and it is very tedious job to write this Condition for all Columns.

I was looking for application column name corresponding to "Draft Invoice Number" ra_interface_lines_all table.
I tried the below.
/* Get descriptive_flexfield_name for the application table name*/
SELECT *
FROM FND_DESCRIPTIVE_FLEXS_VL
WHERE application_id = 222
AND APPLICATION_TABLE_NAME=upper('ra_interface_lines_all');
/* Get the application column name and end user column name*/
SELECT *
FROM FND_DESCR_FLEX_COLUMN_USAGES
WHERE application_id = 222
AND descriptive_flexfield_name = 'RA_INTERFACE_LINES';
There are many DESCRIPTIVE_FLEX_CONTEXT_CODEs obtained. I could finally trace out that draft invoice number corresponds to INTERFACE_LINE_ATTRIBUTE2. How can I know what DESCRIPTIVE_FLEX_CONTEXT_CODE should I look for?
I want to build a single query to fetch the application column name and flex field name for a specific table .

I'm trying to do a pivot query in oracle to get the years from a column and make a separate column for each. I found an example of the code to use on the internet and i changed it for my own tables but i'm getting errors. Namely a "FROM keyword not where expected" error at the beginning of the 'avg(...' statements.
I have copied the code used in
select stud_id, 2006, 2007, 2008, 2009
from (
select stud_id,
avg(case when year=2006 then ((present/poss)*100) else null end) 2006,
avg(case when year=2007 then ((present/poss)*100) else null end) 2007,
avg(case when year=2008 then ((present/poss)*100) else null end) 2008,
avg(case when year=2009 then ((present/poss)*100) else null end) 2009
from attendance.vw_all_attendance_perc
group by stud_id
);

We are using Oracle 11g with Apex 3.2 on AIX. We are reporting data from customer satisfaction surveys. I'm using the following sql to create my report
<code>select * from(
select month,'Overall Satisfaction' as q_group, 1 as srt,Overall Satisfaction,site,
case when count(*) < 31 then '*' else
round((sum(ttos)/count(*))*100,0)||'/'|round((sum(bfos)/count(*))*100,0)||'/'||count(*) end ospct
from v_XXX_report a,(select distinct month_dt month from v_XXX_report) b
where Overall_Satisfaction is not null and year_dt = 2012
[Code]....
The problem is that site is not allways present and sometimes I have other variables in addition to site. This creates a situation where the month columns will not allways appear at the same column number. For example, When I run this query as is then the "JAN" column is Col3 (first column is a break, col2 is not shown). When I run this query without site then "JAN" is the second column. I would like to create column links for the "JAN" - "DEC" columns but not for any other columns.
Another issue - in the column link creation screen I can create up to 3 variables that I can pass to the next page. Since my query is a pivot I'm uncertain how to pass the column heading or the row value (for col2)
ie
Overall Satisfaction JAN FEB MAR APR MAY ...
Overall Satisfaction 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240...
Recommend 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240...
etc.
So if I clicked on the values at Recommend:FEB how can I get "Recommend" and "FEB" into variables that I can use on the next page? I've tried #column_name#, #month#, #q_name# and #APEX_APPLICATION.G_F10# but no luck.

How to select the transactions out of the database that occurred within 70 seconds of each other. The toll_date field is a TIMESTAMP field.
Problem is, I seem to only get transactions that occurred within 70 minutes of each other. On the timestamp field I break the math down into the seconds in a day and I add 70. I then subtract that value and add that value to the timestamp and I should get anything between those values right?
SELECT Acct_ID, Ln, Tag_Rd, COUNT(*)
FROM (
SELECT T1.Account_ID Acct_ID, T1.Tag_Read Tag_Rd, T1.Revenue_Date Rev_Date, T1.Toll_Date, T1.Lane_ID, T1.Plaza, T1.Lane Ln, T2.Toll_Date, T2.Plaza, T2.Lane

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 to create the following table. The fields Trend_Date, Price and Trend are already given. I have to calculate the field permanently and to insert the value in this permanent table.
Fields:
The field price belong to the value of a product during the trade.
The field trade_date belongs to the moment of the trade.
The field trend belongs to the future behavior of the the price. Here, the price of the present moment is compared to the following price (possible characteristics: 'UP', 'DOWN', 'STABLE').
The field permanently belongs to the time (in seconds) how long the value of the field Trend_Date (depending on the price) is still true.
For example:
Row 1: The trend in row 1 is 'UP' and it has a price of '11'. Until row 3 this remains true (the price is greater or equal to 11). In this case, the difference between row 1 and row 3 are 9801 (rounded) seconds.
Row 2: The trend in row 2 is 'DOWN' and it has a price of '12'. This remains true till to the end (the price is never greater than 12) In this case, the difference between row 2 and row 11 are 97346 (rounded) seconds. To calculate the 97346 seconds the field has to consider that between row 2 and row 11 are two days. There will be no trade between 18:00 and 07:00 o'clock. This belongs to 7 hours for each days, in seconds (2*46800) 93600.
-> 190945-93600 = 97346s
Row 6: The trend in row 6 is 'UP' and it has a price of '5'. This remains true till to the end (the price is never smaller than 5) In this case, the difference between row 6 and row 11 are 65729 (rounded) seconds. To calculate the 65729 seconds the field has to consider that between row 65729 and row 11 are one days. There will be no trade between 18:00 and 07:00 o'clock. This belongs to 7 hours for each days, in seconds (1*46800) 46800.
-> 112528-46800 = 65729s
Row 9: The trend in row 9 is 'STABLE' and it has a price of '8'. Until row 10 this remains true (the price is equal to 8 ). In this case, the difference between row 9 and row 10 is 14418 (rounded) seconds.
Row 11: Is empty because there are no values to compare.
Example Table
TRADE_DATE --PRICE --TREND --permanently
02.01.13 11:21:42,720000000--11--UP--9801
02.01.13 12:44:03,236000000--12--DOWN--97346
02.01.13 14:05:03,845000000--11--DOWN--92485
