SQL & PL/SQL :: Selecting Specific Date / Time Range?
May 8, 2013
I want to select a specific date/time range in a query. I want to select from 6 AM yesterday through 6 AM today. I know that CURRENT_DATE - 1 will give me yesterday, and I can search between that and the current_date. However, how do I incorporate the specific time in the query?

10 rows selected.I want the output like as follows, all those missing date i need to carry on the last one's number
The date value I have created for this sample is monthly, based on the condition the data value I may need to generate weekly also. That's Monthly or weekly either one.
I want to reset my date to this format: 12/31/2012 11:59:59 PM - see code below:
DECLARE v_latest_close DATE; BEGIN v_latest_close := TO_DATE ('12/31/2012 23:59:59 ','MM/DD/YYYY HH24:MI:SS'); DBMS_OUTPUT.PUT_LINE('The new date format is : '|| v_latest_close); END;
the code above displays only : 12/31/2012 instead of 12/31/2012 11:59:59 PM
I'm trying to compare a date and time within a certain range.
If the sysdate date/time range falls within the range of the values within the database tables then show a "Yes", otherwise, show a "No". The date works but the time doesn't seem to work. Maybe you can't use a "between" operator for time?
We have a table with timestamp column and having millions of records.We want to create a materialized view or query, which can give count based
-on some group by columns from table and -group by on condition (if count > 1000) and -group by on condition (if timestamp range for that group is > 1hr)
I have a table with a count of customers for about a year, but I only want to select Wednesday and Thursday of each week, starting at the beginning of dates. Table is simple and has two columns. Each row is Distinct to a Date, there are no Date duplicates, it's counted for each day of the year.
column 1: count of customers, count(customer_id) column 2: Date
Not even sure if this is possible to select a date using the day name ?
Basically I want to select each Wednesday and Thursday from each week and compare the counts week over week, over week for all week to see if the counts are going up or down, to get trends .
I would like to inquire how do I code my select statement if my user enter a search date range(search startDt: 01/08/2012 and search endDt :30/09/2012) and I will like to retrieve only the 7records out from my table as shown below ?
I have tried using the max function (select part_no, quantity, max(applied) from pcuk_BG_alloc_TAB group by part_no, quantity) but seems as the records have different quantities it treats them separately.
I'm using apex 4.1.1 And i want to use a Date Picker item on my page. This works, but.. When a user selects a date you can see the date highlighted. But in the "textarea"corresponding tot the datepicker is not showing the date. This shows the date after clicking the close button.
I would like to show the date directly after selecting a new date.
This data needs to be represented in a SQL report as below. The Date Range in the below i.e., Starts with FEB, by checking against the sysdate.. That is from sysdate it will display the Quarter data for 4 months as below.
Currently I am using a procedural logic to populate data into a different table in the above format. Is there any method to do with a single SQL using PIVOT. Below given is the table structure and Insert scripts.
I want my user to be restricted for entering duplicate time within two times.
create table asd(dt_frm date,dt_to date);
insert into asd VALUES(to_date('01-04-2012 08:00','dd-mm-yyyy hh24:mi'),to_date('01-04-2012 10:00','dd-mm-yyyy hh24:mi')); insert into asd VALUES(to_date('01-04-2012 09:00','dd-mm-yyyy hh24:mi'),to_date('01-04-2012 11:00','dd-mm-yyyy hh24:mi'));
now in the second insertion I want to alert the entry user that 9am already falls in the saved record which is 8am to 10am and so that this record can't be saved.
formatting the data.I want to group the below table data based on the Grade column for a header_data with start_time and end_time displayed in range. I was trying with group by, partitions etc but no luck. I use version 10gr2.
When I try to extract the date tag value from XML data, the time stored in 20120602153021 format i.e., YYYYMMDD24HHMISS format. The following statement extracts only date as 02-JUN-12 however do not extract the time part.
If I try the same in SQLplus with to_date it works however fails in PL/SQL.
XML data: <?xml version="1.0"?> <RECORD> <REGTIMESTAMP>20120601130010</REGTIMESTAMP> </RECORD>
PL/SQL Extract:
CURSOR c_xml_record IS SELECT extract(value(d), '//ACTIVATIONTS/text()').getStringVal() AS REGTIMESTAMP, FROM t_xml_data x, [code].......
Other than the obvious to me, where interval partitioning creates partitions as needed. Is there any performance benefit from using interval partitions vs date range partitions.
One draw back for me is that developers do access the partition name in some of their queries, so if I use date range partitioning this will not break their code. I could not find a way to assign a name to a partition when using intervals, is this always system generated or can this be over-ridden.
I am running Oracle 11.1.0.7 soon to be running on 11.2.0.0
I require to find the years between any given date range. For example what are the years between the dates '01/12/2010' and '01/02/2012'? Answer must be '2010,2011,2012'. how to code the query for this result?
Our term (strm) is dictated by the term_begin_dt and term_end_dt dates but I want to keep selecting that term until 1 week before the next term opens and then switch to that term.
Basically, I don't want any gaps between a term.
Output:
select strm when sysdate is between term_begin_dt and term_end_dt (strm would equal 3943) select strm until 1 week before the start of the next term (4027) (strm would equal 3943) select strm when 1 week before term_begin_dt (strm would equal 4027)
Repeat for the next term and so on 12/16/2011 select strm from term where trunc(sysdate) between trunc(term_begin_dt) and trunc(term_end_dt)
Output: 3943 12/17/2011 - 01/01/2012
select strm from term where ?
Output: 3943
01/02/2012 - 5/4/2012 select strm from term where ?
Output: 4027
Repeat.
Test Case:
CREATE TABLE TERM ( STRM VARCHAR2(4 BYTE), DESCR VARCHAR2(20 BYTE), TERM_BEGIN_DT DATE, TERM_END_DT DATE )
Insert into TERM (STRM, DESCR, TERM_BEGIN_DT, TERM_END_DT) Values ('3943', '2011 Fall Semester', TO_DATE('08/22/2011 00:00:00', 'MM/DD/YYYY HH24:MI:SS'), TO_DATE('12/16/2011 00:00:00', 'MM/DD/YYYY HH24:MI:SS')); Insert into TERM [code].....
I am trying to replace a date range in a query. Don't understand why it's not working, below is the dummy query for the same:
/* v_Employee:= 'select emp_name from employee_table where Join_Year=~Replace1~ and Release_Month <=~Replace2~'; v_Replace1:=2013; v_Replace2:=7; pos := 1; WHILE (INSTR(v_Employee, '~', 1, pos) <> 0) LOOP IF (pos = 1) THEN
[code]....
Since actual code is like CLOB type, so I have not provided the same. Here after executing this query i found that v_Employee query is getting replaced by v_Replace1 at both of his position i.e "select emp_name from employee_table where Join_Year=2013 and Release_Month <=2013"
But my actual result should: "select emp_name from employee_table where Join_Year=2013 and Release_Month <=7"
I have a table which has 2 range partitions on a date column currently.
CREATE TABLE TABLEA ( RUN_TIME INT NOT NULL ) PARTITION BY RANGE (RUN_TIME) ( PARTITION DATAONE VALUES LESS THAN (20110101000000) TABLESPACE SPACE1 PARTITION DATATWO VALUES LESS THAN (MAXVALUE) TABLESPACE SPACE2 );
I am planning to drop one partition i.e DATAONE. So table will have one partition left for MAXVALUE. Does it make sense to have a partition with MAXVALUE? Isn't it same as TABLEA in terms of number of records? TABLEA is also in tablespace SPACE2. Should i remove partition DATATWO also? If i have to what is the best way to move all DATATWO records to base table TABLEA?
