I am trying to check for dates but after running the query below, it displays no result. Could someone recommend me the correct syntax?
SELECT TOP 10 * FROM MY_DATABASE.AGREEMENT
WHERE end_dt=12/31/9999
12/31/9999 might look like a date for you but for the database it's a calculation:
12 divided by 31 divided by 9999 and because this involves INTEGER division this results in an INTEGER 0
So finally you compare a DATE to an INT and this results in typecasting the DATE to a INT.
The only reliable way to write a date literal in Teradata is DATE followed by a string with a YYYY-MM-DD format:
DATE '9999-12-31'
Similar for TIME '12:34:56.1' and TIMESTAMP '2014-08-20 12:34:56.1'
Is it a date column? Then try where end_dt = '9999-12-31'.
The question you ask is not very clear. The date you specify is language dependent.
Try
SELECT TOP 10 * FROM MY_DATABASE.AGREEMENT WHERE end_dt='99991231'

When I write below query it gives record .
SELECT [srno],[order_no],[order_date],[supplier_name],[item_code],[item_name],[quntity]
FROM [first].[dbo].[Purchase_Order]
WHERE order_date BETWEEN '22/04/2015' AND '4/05/2015'
In this query if I don't add 0 in '4/05/2015' it returns record.
But when I add 0 to the date i.e. '04/05/2015' it doesn't give any records.
SELECT [srno],[order_no],[order_date],[supplier_name],[item_code],[item_name],[quntity]
FROM [first].[dbo].[Purchase_Order]
WHERE order_date BETWEEN '22/04/2015' AND '04/05/2015'
The reason it's not working because SQL is trying to do a string comparison because both your types are string types, But what you really want to do a date comparison.
You should do something like this. Since you only need date part you can strip off the time and use style 103 for your format dd/mm/yyyy.
WHERE CONVERT(DATETIME,LEFT(order_date,10),103)
BETWEEN CONVERT(DATETIME,'20150422') AND CONVERT(DATETIME,'20150504')
Alternately you can use this as well if your order_date has dates like this 5/4/2015 03:20:24PM
WHERE CONVERT(DATETIME,LEFT(order_Date,CHARINDEX(' ', order_Date) - 1),103)
BETWEEN CONVERT(DATETIME,'20150422') AND CONVERT(DATETIME,'20150504')
A long term solution is to change your column order_date to DATE/DATETIME
It Better to Cast it to date rather than depend on IMPLICIT conversion
SELECT [srno],[order_no],[order_date],[supplier_name],[item_code],
[item_name],[quntity] FROM [first].[dbo].[Purchase_Order] where
convert(date,order_date,105) BETWEEN cast('22/04/2015' as Date) AND cast('04/05/2015' as date)
I have a table with a LOAD_STRT_DTM colum. This is a date column and values are like this - 18-JUL-14 08.20.34.000000000 AM.
I want to find the data which came before 5 days.
My logic is -
Select * from Table where 24 *(To_DATE(Sysdate,'DD-MM-YY') - To_DATE(LOAD_STRT_DTM,'DD-MM-YY')) >120
The issue is -
Select (To_DATE(Sysdate,'DD-MM-YY') - To_DATE(LOAD_STRT_DTM,'DD-MM-YY')) from table
This query should give the NumberOfDays between two dates. But this is not working, I Doubt, the issue is because of the format of the LOAD_STRT_DTM colum.
Please let me know where i am doint it wrong.
If your column is DATE datatype everything is ok, just shoot an:
select * from table where LOAD_STRT_DTM > sysdate - 5;
No need to convert dates to DATE datatype.
(To_DATE(Sysdate,'DD-MM-YY') - To_DATE(LOAD_STRT_DTM,'DD-MM-YY'))
You don't have to convert a DATE into a DATE again. IT is already a DATE. You just need to use it for date calculations. You use TO_DATE to convert a STRING into a DATE.
For example, if you have a string value like '18-JUL-14', then you would need to convert it into date using TO_DATE. Since your column is DATE data type, you just need to use as it is.
This is a date column
I want to find the data which came before 5 days.
Simply use the filter predicate as:
WHERE load_strt_dtm > SYSDATE - 5;
NOTE : SYSDATE has both date and time elements, so it will filter based on the time too. If you want to use only the date part in the filter criteria, then you could use TRUNC. IT would truncate the time element.
I have answered a similar question, have a look at this https://stackoverflow.com/a/29005418/3989608
It looks like LOAD_STRT_DTM is a TIMESTAMP rather than a DATE, given the number of decimal points following the seconds. The only thing you have to be cautious about is that Oracle will convert a DATE to a TIMESTAMP implicitly where one of the operands is a TIMESTAMP. So the solution
WHERE load_strt_dtm > SYSDATE - 5
will work; as will
WHERE load_strt_dtm + 5 > SYSDATE
but the following will not:
WHERE SYSDATE - load_start_dtm < 5
the reason being that TIMESTAMP arithmetic produces an INTERVAL rather than a NUMBER.
first convert two dates to same format select datediff(dd,convert(varchar(20),'2015-01-01',112),convert(varchar(20),'01-10-2015',112))
I dont have proper timestamp in table; is it possible to delete 1 day old logs even now?
I have a column name as SESSION_IN which is basically a VARCHAR datatype, and the value will be like
2013-10-15 02:10:27.883;1591537355
is there any way to trim the number after ; and is it possible to compare with "sysdate" identifier?
This SP should compare all the session IDs with current datetime and it should delete if it is older then 1 day.
You can igonre time part and convert date into required format somthing like this
SYSDATE - to_date('date_col','YYYY-DD-MM')
then you can perform operations.
Use the Substring function to extract the datetime portion from the record, then use convert to datetime to cast it to datetime, and then finally use datediff to check if it was inserted yesterday. Use all these caluses in a
DELETE FROM table
WHERE ___ query
For Oracle you could use something like this:
SELECT
TRUNC(to_timestamp(SUBSTR('2013-10-15 02:10:27.883;1591537355',1,
(
SELECT
instr('2013-10-15 02:10:27.883;1591537355', ';')-1
FROM
dual
)
), 'YYYY-MM-DD HH:MI:SS.FF'))
FROM
dual;
Which gives you just the date portion of your input string. Just subtract the amount of days you want to log at the end.
Hope following query helps you:
Select Convert(Datetime,Substring('2013-10-15 02:10:27.883;1591537355',1,23)), DateDiff(dd,Convert(Datetime,Substring('2013-10-15 02:10:27.883;1591537355',1,23)),Getdate())
Can someone explain to me why when I perform a LIKE select in SQL (T-SQL) on a varchar column I can do the following:
SELECT *
FROM Table
WHERE Name LIKE 'Th%'
to get names beginning with Th, but when I do the same on a datetime column I need a % before the year, like:
SELECT *
FROM Table
WHERE Date LIKE '%2013%'
to get dates in 2013. The datetimes are stored in yyyy-MM-dd hh:mm:ss format. I know I could use a DATEPART style query but I was just interested in why I need the extra % here.
The DATETIME is converted to a VARCHAR before the comparison, and there definitely is no guarantee that the conversion will be in the pattern you mention. DATETIME is not stored internally as a VARCHAR but as a FLOAT.
You should stop wondering because the syntax is not useful.
SELECT *
FROM Table
WHERE Date LIKE '%2013%'
Will give you a full table scan because the date will be converted to a varchar when comparing. In other words, don't do it !
Use this syntax instead:
SELECT *
FROM Table
WHERE Date >= '2013-01-01T00:00:00'
and Date < '2014-01-01T00:00:00'
If the Date field is in timestamp:-
SELECT *
FROM Table
WHERE year(Date) = '2013'
The sql server converts datetime to this format (Jan 1, 1900 9:20AM.)Because of that reason We need to use an extra %.
If you want to search the records start with month Jan
you can use following query for date time
SELECT *
FROM Table
WHERE Date LIKE 'Jan%'.
No need of extra '%'.
I have a table student with the following columns:
no - integer
name - string
startdate - date
enddate - date.
Date format is MM/DD/YYYY.
I will give a date as input. Now I need a query the inputdate which found in between the start and end date.
For an example I will give 04/14/2012, then the query should return the 1st record as in the figure.
(because input date (04/14/2012) is found in between the 04/10/2012 to 04/20/2012)
Please help me.
The issue you are having is caused by your assumption that sqlite has a date/datetime type when in fact it doesn't.
I suggest you read the following http://www.sqlite.org/datatype3.html to have a better understanding of sqlite types.
The dates in the MM/DD/YYYY format are handled as TEXT by sqlite, and so those dates are compared as strings. For example, 02/01/2012 is considered bigger than 01/02/2012by sqlite if compared directly.
You will need to transform those dates to a format that can be string-compared. Here is an example:
sqlite> create table foo (d TEXT);
sqlite> insert into foo values ('02/01/2012');
sqlite> select substr(d, 7, 4) || substr(d, 1, 2) || substr(d, 4, 2) from foo;
20120201
You should post what you have tried so far.
There should be a between clause that you can use:
select * from table
where inputdate between startdate and enddate
Dates as a date type in SQLite don't exist. There are a number of approaches to dealing with dates - store them as integer seconds since 1 Jan 1970 (unixepoch) or store them as strings, but if you do, then you really need to store them in 'YYYY-MM-DD' format because that is what the date functions require as input.
Assuming you use the string format in the format I suggested then your query would look something like
SELECT * FROM Table WHERE Date(Inputdate) BETWEEEN Date(startDate) AND Date(EndDate);
(although you may want to format the output of the date columns to US date format with
SELECT Strftime("%m/%d/%Y",startDate) As StartDate ...
If you use seconds since 1970 its somewhat easier because the seconds just compare without needing the convert them to dates, although you still might want to output in US date format, so ...
SELECT Strftime("%m/%d/%Y",startDate) As StartDate ... FROM Table WHERE inputDate BETWEEN startDate and EndDate;
sqlite> select *from tbl_node where mydate between '2014-02-02' and '2014-02-06';
it show the output :-
1|1|123|456|12eb-ab|1|1|254|123|19|2014-02-03 16:00:44
2|1|123|456|12eb-ab|1|1|254|123|19|2014-02-03 16:01:03
3|1|123|456|12eb-ab|1|1|254|123|19|2014-02-03 16:00:57
4|1|123|456|12eb-ab|1|1|254|123|19|2014-02-03 16:00:34
Here mydate is column name in tbl_node;
we can also use from current time , using now.
sqlite> select *from tbl_node where mydate between '2014-02-02' and 'now';
