Comparing Dates (older Than)
Feb 21, 2007
Hi Guys,
I am really stuck on exactly how I can do this. I can sudo it in my mind but can't figure out how I would code it.
What i want to do is select all records from a table that the log_date is older than 7 days.
If I was comparing a date i would imagine i would do something like
log_date < NOW()-7
I have looked at:
SELECT player_name, player_last_logon_date,DATEDIFF(day, player_last_logon_date, GETDATE()) AS NumberOfDays from player
select player_name, player_last_logon_date, datepart(dd,player_last_logon_date) from player
but I dont think either is really right. any and all advice would be great!
Thanks

Hello,
I am trying to retrieve the data that are not more than 3 months. How do I do this? The closest thing that I can do is...
(dbo.CLASSIFIEDADS.PostDate > CONVERT(DATETIME, '2006-03-26 00:00:00', 102))
I want to be able to put 3 months in there somehow...
Thanks in Advance!

I am wondering how I would create a SELECT that will select the most recent date from one of two tables. For example, table1 has a field called LastUpdate and table 2 has a field called LastUpdate. I need to grab only the most recent date. I tried this using an inner join...but that didn't work because it only picks the lastupdate form one table only. talbe1 and table2 are tied by table2.table1id.
Can anyone help?

Hi All,
I have a database field (datestamp) which returns the date the records were inserted into the database. The datestamp was created with the now(); function in .net and is in the following format: 5/23/2006 2:27:45 AM
I basically want to return all records that were inputted more than 28 days ago. I have had alook though some other posts and below is the closest query that i could find but unfortunately it does not work for me.
SELECT id, datestampFROM table WHERE datestamp > DateAdd(d, 28, GetDate())
Thanks in advance,
Jake

How do i compare 2 dates without comparing their Time portions. I have a Datetime column in my table which for example has values :-
6/6/2001 7:23:42 PM
6/6/2001 8:01:08 PM and so on....
I have a Stored Procedure in which i am trying to fetch values from this table. The SP has 2 DateTime parameters @DateFrom and @Dateto. This SP is called from a Web page. On the Web Page the user just enters mm/dd/yyyy values for the 2 Date parameters. Therefore the Time portions defaults to 12:00 AM. So when the user passes 6/6/2001 as Date From and 6/6/2001 as Date To values, he doesn't get back the 2 records mentioned above since the Time portion makes the 2 records fall out of the date range.
Is there a way to just do a comparison on the Date portions i.e. give me all the records for 6/6/2001 irrespective of the time. I don't wan't to do individual comparisons for Day then Month and then Year.
Thanks
Sanjay.

i am using sql server ver 7
i am trying to do
select *
from independent_investment_certificate_temp
where independent_investment_certificate_temp.ticker_key = 31
and convert(varchar(40), cast(independent_investment_certificate_temp.maturity_date AS datetime),107) >
convert(varchar(40), cast('2006-12-10 10:29:50.733' AS datetime),107)
independent_investment_certificate_temp.maturity_date value is '2005-01-21 00:00:00.000'
the query above returns a value even though '2005-01-21 00:00:00.000' is clearly < '2006-12-10 10:29:50.733'
but why can anyone plz explain.. how can i compare dates stripping tyhem of the time so that all dates on the same day will be
equivalent regardless of the time

Hi, i got this query below, which I'd like to use to compare two sets of date...
select count(*) as rec, convert(char(6),dateEntered,13) as dateEntered from EmailTracker where chtype = '1' AND convert(char(12),dateEntered,13) >= '"& stdate &"' AND convert(char(12),dateEntered,13) <= '"& endate &"' group by convert(char(6),dateEntered,13)
the format of the stdate and dateEntered (a datetime datatype) looks like - 25 Aug 2005
right now, the query simply uses the first 2 letters of the date to fetch the record. That would not do the job as i want the thing to compare the whole lot! not just the 1st two letters...
Any help pls?

Does anyone know of a quick and easy to compare 2 datetime values based only on the month and year.
For example,
FromDate = 11/30/2004
ToDate = 12/30/2004
I just need to compare the 11/2004 to 12/2004 using function like <=, =, >=, etc.
Any suggestions?
Thanks

I will try to explain my problem as best as possible without going into too much detail.
Basically I have two tables,
AgentSchedule
AgentPunchData
These tables both contain agent names.
The schedule table has a column called "SHEND" which is a DATETIME datatype which identifies when an agent shift should end.
The entries all have a date attached which means nothing, for example "12/30/1899 9:00:00 PM"
The PunchData table has a column called "LOGOUT" which is also a DATETIME, the entries will have the real date and look something like this: "3/28/2008 9:23:00 PM"
I need to strip the date out of these functions so I can compare the times. I need to query the databases and return any instances where the LOGOUT time is > the shift end time (SHEND).
So far nothing I've tried has been successful. I'm completely stumped, I've tried so many different things and nothing compares the two times correctly. SQL DATETIME is the biggest pain in the ass, I wish we had SQL 2008 so I could just use TIME.

Hello,
I have some code that is trying to first find the first date of service that a person visited. Using the min function is not working. Is there another function? Right now I am still getting multiple rows for each person instead of just the first visit.
Then I want to be able to compare the first date of service to the date of birth and determine if the patient first visited before they were 2 years old. I can't figure out how to do this.
select distinct b.person_id,b.date_of_birth,min(a.enc_timestamp)
from patient_encounter a
join person b on a.person_id = b.person_id
where b.date_of_birth >= '20060301' and b.date_of_birth <= '20060531'
group by b.person_id,b.date_of_birth,a.enc_timestamp

Basically, Im trying to return some data from an Access library database into a Java app using an SQL statement. Heres the code:
PHP Code:
Statement st = conn.createStatement();
String sql = "SELECT b.BorrowerNo, b.FirstName, b.LastName, COUNT(*) " +
"FROM Borrowers b, Loans l WHERE l.BorrowerNo = b.BorrowerNo " +
"GROUP BY b.BorrowerNo, b.FirstName, b.LastName ORDER BY COUNT(*) DESC";
ResultSet rs = st.executeQuery(sql);
This works fine, returns the BorrowerNo, FirstName, LastName, and COUNT is how many books they have loaned.
What I need it to do though, is just return loans that are late. I have a column in the Loans table called DateDueBack, so I think I need to compare this date to the current date in the WHERE statement.
I tried add this to my WHERE after l.BorrowerNo = b.BorrowerNo: AND l.DateDueBack > 16/11/2005
But this didn't work, it returned all the loans, regardless of whether they were before or after the date in the query.
Can anyone please help with this statement? I've never tried to compare dates before.

Hi All,
Is there a way to compare two dates fields that are different in length? For example, I have table1.datefield with a date of '040808' and table2.datefield with a date of '04082008'. Just comparing the two fields is not coming up equal. Has anyone had this situation before?
Thanks.

I have a date comparison situation in which I will have a column with a date and will have another value containing a GETDATE() minus two weeks. I want to be able to compare both dates and get the MIN date between the two. I'm not sure how to use the MIN(Date) in this scenario since the comparison won't be between two different columns, but between one column and a random date generated by the GETDATE() minus two weeks.

Hi,
I have a table that holds pay rate changes with a field for the rate start date and a field for the rate end date. When an employee gets given a new pay rate, the existing rate is given an end date and a new row is added with the rate start date being the day following the end date of the old pay rate.
I need to identify the staff who have had a rate change within the past month, therefore an end date on one row that is within one month of the current month, and a start date on another row that is one day after an end date on a separate row and within one month of the current month.
Is someone able to help me out please?
Thanks

Hi,
I have a table that temporarily stores information. Before I insert new data in the table, I want to delete the previous day's data.
This is the query I'm using
Code:
q="DELETE FROM SearchTemp WHERE theDate < "&Date()
set RS2 = DB.Execute(q, ra, adCmdText)
I should say I'm using ASP & VBScript.
Problem is, this isn't deleting the previous day's dates.
The dates are stored in this format: m/d/yyyy.
I've searched through old posts but none of the solutions offered have worked for me so far. Anyone have any suggestions?
Thanks!

Hi,
Below is my store procedure. I am trying to capture all orders between a startdate and a enddate. When I use the Where #1(see below- I have 2 where clauses) it allows me to go from one year to another. For example, startdate of 2/18/2003 - enddate of 2/19/2004 will return all orders in my table except for 2/19/2004. Probably because of the time portion.
When I use the Where #2, it doesn't go back a full year. The startdate is reacting like 2/18/2004 and not 2003. The records I get are only for dates 2/18/2004-2/19/2004.
How do I create a where clause which will go back a year or more and include the enddate orders? Any help will be very much appreciated.
Thanks,

To the experts in the field:
There is probably a very simple solution that is avoiding my grasp.
I have a For Loop which I want to execute as long as a variable called BeforeRunDt = CurrentDate. Both are DateTime data types and I am using the following expression:
@BeforeRunDt==@CurrenDate
I get an error stating "Cannot convert expression value to propeerty type"
I understand that the result of the expression should be a boolean value but am just struggling on how to create it.
Thanks!

Hi All
Can anyone help me to keep track of older view or stored Procedure that has been altered so that I can compare the two and make out the changes that have been made.At present I 'm able to get just the altered view or storedProcedure but how to know that what has been changed.
This will be somewhat similar to Instead if and after in DML trigger but DDL triggers doesn't supports it.If anyone is aware of something then please help

I have a backup job that has failed.
The database size is 20.6 GB and the Transaction logs are 135MB
The amount of disk space I have left is 3.65MB. Which I know is not going to work.
However on the maintenance plan it is suppose to remove files older than 1 day.
I am wondering if a job works like this:
Step 1 create backup file
Step 2 Create Transaction Log Back up
Step 3 Delete old backup file
Step 4 Delete old Transaction log back up
Which tell me I would need to have double amount of disk space to accommodate 2 20 GB backup file and 2 135MB Transaction log file.
Is this correct??
Also is there a way that I can have step 3,4 done first.

Is it possible to send a email after a certain date has pass by. And 2 days after the email has been sent the post should be removed if the member doesn't answer the message.
example: The posts should not be older then 2 months. When they get older than 2 months the SQL-Server detects this post and sends a messegae to the member if he wants to renew it. If he ignors it for 2 days after the email the post will be removed from the database. (Some posts have images also, They should also be removed from the harddrive)
Is this possible in MSSQL-Server to send email?
If someone could tell me how to create this.

Hello ,
I am little confused in writing the exact query i.e filling the correct details in the query .
To simplify let me explain....
I am using the query as
delete MYTABLE
where datediff(dd,loaddate,getdate())>5
I have a table now with loadate column which gets the default date and time . The loadate shows correct date and time when the data was imported in the table .
Now suppose if i want to delete previous 5 days records from today
( for e.g today is 20/08/2002 3:40:00 PM ) ideally it should delete all records which are 5 days older from today . i.e from 20/08/2002 3:40:00 PM to 15/08/2002 3:40:00 PM )
But when i execute the datediff command , it deletes the records previous than 15/08/2002 till 15/08/2002.
The records from 15/08/2002 to 20/08/2002 remain intact .
I am getting some different results .
Am i missing something in the query or i am confused about the calculation of the dates the datediff command performs .
Is the logic correct or i am missing someting important ?
Thanks and Regards

I am in the process of moving a database to a new location. My problem is that I do not have the most recent full backup file. I have a previous full backup file and I also have all of the transaction log backups from the time of the old backup to the present time.
My question is, do I need the most recent backup to restore the database, or can I do it with the older backup plus the transaction log backups?
Thanks in advance.
