I ran this following query and somehow i feel the results are wrong.
SQL> select to_char(starttime,'dd-mm-YYYY hh24:mi:ss') from report where dateofmonth between to_timestamp_tz('22-Apr-2013 12:00:00','dd-mm-YYYY hh24:mi:ss') and to_timestamp_tz ('23-Apr-2013 14:00:00','dd-mm-YYYY hh24:mi:ss');
SQL> select to_timestamp_tz(starttime,'dd-mm-YYYY hh24:mi:ss') from report where dateofmonth between to_timestamp_tz('22-Apr-2013 12:00:00','dd-mm-YYYY hh24:mi:ss') and to_timestamp_tz ('23-Apr-2013 14:00:00','dd-mm-YYYY hh24:mi:ss');
Have a table which has 3 columns id,name,time where time is of datatype timestamp and it stores the time when the row was inserted. Need an query which accepts 2 parameters as input Ex: Start_Time,End_Time and all the rows in between the above mentioned timestamps must be deleted.
the data guard configuration is left as it is, i.e.
cta: physical standby ctastd: primary
I discover the following findings in the alertcta.log, i.e. in cta database,
Primary database is in MAXIMUM PERFORMANCE mode RFS[8]: Successfully opened standby log 4: 'D:ORA102CTAREDO04.LOG' Thu Sep 01 10:38:08 2011 Errors in file d:ora102ctaudumpcta_rfs_536.trc: ORA-16401: archivelog rejected by RFS
Quote:
ORA-16401: archivelog rejected by RFS
Cause: An attempt was made to re-archive an existing archivelog. This usually happens because either a multiple primary database or standby database(s) or both are trying to archive to this standby database.
Action: See alert log and trace file for more details. No action is necessary; this is an informational statement provided to record the event for diagnostic purposes.
it seems to be that there are multiple primary database, but it is not based on the information from v$database.Right now the physical standby database cannot received any archive logs from the primary.I've checked the database_role in both servers, they are as they are designated.
from the physical standby database
SYS@cta>select db_unique_name, database_role, switchover_status from v$database; DB_UNIQUE_NAME DATABASE_ROLE SWITCHOVER_STATUS ------------------------------ ---------------- -------------------- CTA PHYSICAL STANDBY NOT ALLOWED SYS@cta>alter database recover managed standby database disconnect from session
[code]....
the standby is always busy, i.e. SESSIONS ACTIVE. i.e make sure the archived logs are shipped and apply over to physical standby.
I have a 10gR2 standby database.Normally when logs are created in primary they automatically get shipped to standby but sometimes I get FAL request rejected or connection lost contact error and the logs are not automatically shipped .
Then when I manually switch a logfile the RFS process copies the old logs into DR site(around 4 or 5 logs).What is the problem...How to resolve this???
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?
view the below select statement..why it's adding extra zero's...
select to_timestamp('2001-05-22 12:00:18.600','YYYY-MM-DD HH:MI:SS.ff3AM') from dual output: 5/22/2001 12:00:18.600000000 PM ---why it's adding extra zeors's my output should be as " 5/22/2001 12:00:18.600 PM"
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.
i m creating the dynamic table every month to maintain the particular month data seperately .when the records getting inserted in the table,trigger will automatically insert the records in the dynamic table. only date alone(without timestamp) getting inserted in the dynamic table from staging. so by default ,00:00:00 is getting appended with date instead of actual timestamp. tried select to_date(to_char(:new.ACTN_DATE,'YYYY-MM-DD HH24:MI:SS'),'YYYY-MM-DD HH24:MI:SS') INTO v_temp_actn_date from dual; but i am getting only date alone . in my table and dynmaic table datatype for date column is date
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.
how to caluclate days between two dates of single timestamp filed and with this
query Select * from m_activity_transaction where actn_opp_id in ( Select actn_opp_id from m_activity_transaction where ACTN_ACTV_ID = 218 Group by actn_opp_id
[code]...
and i nedd to caluclate no.of days between two dates like 27-JAN-12 11.06.20.000000 AM and 08-FEB-12 05.32.54.000000 PM where actn_id is unique AND ACTN_OPP_ID IS NOT UNIQUE.
Is there a way to query an oracle database in an automated fashion by a timestamp field based on current timestamp, like: 04/29/08 00:00:00 - 72 hours?
(both these fields a_std and a_time are coming as varchar from the parent table in a cursor.(basically they are time period and actual arrival time respectively)
i was juggling with the attempt to make varchar to timestamp or date..but caught with Round up /Round down)
Formula ->
A = Round down [A_TIME - A_STD] B = Round up [A_TIME) - 10 minute + A_STD]
where
A_TIME VARCHAR2(8) N Time (Format" HH:MM AM/PM") eg "3:50 PM" A_STD VARCHAR2(5) N Standard time (Format" HH:MM") eg "1:00"
Allowed values for A & B after round up/down = multiple of 10 ( 11:00,11:10,11:20 etc.)
I have 3 tables, user_login_event, person and resource_viewed_event. What I want to do have a report for each month, users logged in our application and then show for each month, how many records were created in table person and how many resource views events were logged in resource_viewed_event.
Lets only worry about the timestamp fields in these tables now as I want to use them to join the tables together or at least build correlated subqueries along the months. I have tried several options, all not leading to a desired result:
Left outer join. Works but its incredibly slow:
SELECT distinct to_char(ule.TIMESTAMP,'YYYY-MM') as "YYYY-MM", count(distinct ule.id) as "User Logins", count(distinct ule.user_id) as "Users logged on", count(distinct p2.id) as "Existing Users", count(distinct p1.id) as "New Users", count(distinct r1.id) as "Resources created"
[code]....
Tried the same with left outer joins of temporary tables created through select statements:
select distinct ule.month as "Month", count(distinct p1.user_id) as "Users created", count (ule.id) as "Logins", count (distinct ule.user_id) as "Users logged in", count(rv.id) as "Resource Views", count(distinct rv.resource_id) as "Resources Viewed"
[code]....
Tried the same with left outer joins of temporary tables created through select statements:
select distinct ule.month as "Month", count(distinct p1.user_id) as "Users created", count (ule.id) as "Logins", count (distinct ule.user_id) as "Users logged in", count(rv.id) as "Resource Views", count(distinct rv.resource_id) as "Resources Viewed"
[code]....
another approach is to create my own temporary tables using select statements and create fixed Month values which I can use to directly link the sets together.
select distinct ule.loginday as "Month", count(distinct ule.id) as "Logins", count(distinct ule.user_id) as "Users logged in", count(distinct p1.user_id) as "Users created", count(distinct p2.user_id) as "Existing users1"
[code]....
performance is OK with 2 tables but the example above takes forever to execute.
Tried an approach with union but this creates new rows for each table
SELECT DISTINCT p1.MONTH AS "Month", COUNT(DISTINCT p1.user_id) AS "Users created", NULL AS "Logins", NULL AS "Users Logged in", NULL AS "Resource views", NULL AS "Resources viewed" FROM (SELECT To_char(person.created_on_date, 'YYYY-MM') AS MONTH,
drop table test / create table test ( lib varchar2(100) ) / insert into test values ('111/aaa/bbb/ccc'); insert into test values ('222/aaa/bbb/ccc'); insert into test values ('333+444/aaa/bbb/ccc'); insert into test values ('333/aaa/bbb/ccc'); insert into test values ('222+333+444/aaa/bbb/ccc'); insert into test values ('222+333+444+555/aaa/bbb/ccc');
I need to transpose the following table columns to rows and rows to columns...Im not quite sure how to acheive this...I have the following table with fixed number of columns and dynamic number of rows based on date filter in query
MONTH_YEAR RMS RMS_OCC TTL_RMS --------------------------------------- SEPTEMBER 200917790017790 OCTOBER 2009183831278818347 NOVEMBER 2009177901460517762
and I need to display this as
COL1 SEPTEMBER 2009 OCTOBER 2009 NOVEMBER 2009 -------------------------------------------------------------- RMS 17790 18383 17790 RMS_OCC 0 12788 14605 TTL_RMS 17790 18347 17762
We are using PL/SQL Release 11.2.0.2 .I would like to pull a query with each student each day an attendance record.Our database setup an AM and PM Period for all elementary students. I will pull if they absent both periods(AM, PM), then count that as one day absent.The hard part is I need to put the AM absent code and PM absent code - which is basically to put two records for each student's AM and PM absent code into one row.
Below is the query I use, but it violates the key of database, for PK is studentid+ attendance date. My query result turns out for some students they have different attendance code in AM vs PM, there are two records returned.
We have large (millions of records) Slow changind dimension (SCD) type 2 (see "Creating another dimension record " URL>.....We need to get several rows from this SCD for each key (AGREEMENT_ID) in a SQL query - to join to facts table and get several data points of each agreement (on several different points in time) stored in SCD.Here is SCD table structure:
CREATE TABLE AGREEMENT ( "AGREEMENT_ID" NUMBER(*,0) NOT NULL ENABLE, "ACTUAL_DATE" DATE NOT NULL ENABLE, "ACTUAL_END_DATE" DATE NOT NULL ENABLE, "OPEN_DATE" DATE NOT NULL ENABLE, "LIMIT" NUMBER(23,8) --++ a lot of other fields not needed for this task .... CONSTRAINT "PK_MD_AGREEMENT" PRIMARY KEY ("AGREEMENT_ID", "ACTUAL_DATE") USING INDEX )
The 1st simple approach would be to join facts to SCD as many (N) times as many different points of time you need - resulting in N Full Table Scans for SCD:
select ... from fact, AGREEMENT agr1, AGREEMENT agr2, AGREEMENT agr3 where fact.AGREEMENT_ID = agr1.AGREEMENT_ID and agr1.open_date between actual_date and actual_end_date and fact.AGREEMENT_ID = agr2.AGREEMENT_ID and :dateBOP between actual_date and actual_end_date and fact.AGREEMENT_ID = agr3.AGREEMENT_ID and :dateEOP between actual_date and actual_end_date
2nd approach: 1 Full Table Scan for SCD + group by:
select ... from fact, ( Select AGREEMENT_ID, max(case when open_date between actual_date and actual_end_date then LIMIT end) LIMIT_At_Open_DATE, max(case when :dateBOP between actual_date and actual_end_date then LIMIT end) LIMIT_At_BeginOfPeriod_DATE, max(case when :dateEOP between actual_date and actual_end_date then LIMIT end) LIMIT_At_EndOfPeriod_DATE
from agreement
-- ++optionally WHERE for those 3 dates, but possibly with no effect on non-partitioned table? Or WHERE to put less data on MAX() input (3 row for each agreement instead of 4...1000 without WHERE?)
group by AGREEMENT_ID ) agr where fact.AGREEMENT_ID = agr.AGREEMENT_ID
Simple question, Why comparison operator ANY returns FALSE if no rows returned, and why operator ALL return TRUE if no rows returned? I dont know is this some kind of language or math assumption or is this just oracle rule?
There are at most 2 entries of a in b. Depending on the value of the type column in B, this determines whether the entry should be male or female. I want to have a select statement that will retrieve 2 rows into one row essentially like below, how is this done:
id male_name female_name 1 paul paula
the column names will appear as such, if its a 0 its a male name if its 1 its a female name, there will generally be 2 entries in B for 1 value of a.
