Putting Date Or Date && Time In A Column Thats Going To Be Heavily Used?
Oct 4, 2007
Hello,
We have a bunch of Audit tables that contain almost exact copies of the operations tables. The audit tables also include:
AuditID - the audit action (insert, modify - old, modify - new, deleted)
AuditDate - date and time of action
AuditUser - User who did it...
At the end of the day I need to know for any given record what it looked like at the beginning of the day and what it looks like at the end of the day. There could have been numerous changes to the record throughout the day, those records I am not interested in. Only the first record and the last record of a give day.
I am going to be doing a lot of MIN(AuditDate) and MAX(AuditDATE) and .. WHERE AuditDate BETWEEN '10/1/2007 00:00:00' AND '10/1/2007 11:59:59' ...
Question: Whats better for performance:
1. Separating out the date and time and doing a clusterd index on the date.
2. Keeping date and time in the same column and just use a normal index.
Here's what I want: I have a DTSX package run as a SQL Server agent job, that each time it runs I want it to create a new log file with the date & time in the filename. e.g. MyJobLog.20080311_103613.txt
I have implemented this using the SSIS log provider for Text Files, and defining the Connection String as an expression as follows:-
Here's the problem:- When the job runs, each time it tries to write to the log file it re-evaluates the filename, and as the seconds pass by the name changes! So instead of one file I end up with several:- e.g. MyJobLog.20080311_103613.txt MyJobLog.20080311_103614.txt MyJobLog.20080311_103615.txt
So the one execution of the job is now divided across three files! This is not what want!
Here's one way I fixed it:- One of my Jobs is run from an MS-DOS batch file, so I was able to pass the constructed date/time sting into the DTSX file as a parameter. This works perfectly.
Here's my problem:- Three more of my jobs are run as scheduled job from SQL Server Agent, so I can't pass in the date/time as a parameter each time (unless you know otherwise). And the clients' security policy won't allow the job to call an MS-DOS batch file which runs the DTSX package. Or is there really some other way to stop the Log filename from re-evaluating on every write?
I have an SSIS package that moves data from SQL Server to an legacy Access database. In SQL Server, there is a date/time column that I need to split into a separate date column and time column in the access database. Initially I just created a derrived column for the time and set the expression equal to the source date/time column from SQL Server. Unfortunately, that just makes the date column and time column the same having the full date/time.
What expression can I use during a derrived column transformation to assign just the date to a derrived column and just the time to another derrived column?
I'm trying to extract some data from a table in oracle. The oracle table stores date and time seperately in 2 different columns. I need to merge these two columns and import to sql server database.
I'm struggling with this for a quite a while and I'm not able to get it working.
I tried the oracle query something like this,
SELECT (TO_CHAR(ASOFDATE,'YYYYMMDD')||' '||TO_CHAR(ASOFTIME,'HH24:MM : SS')||':000') AS ASOFDATE
FROM TBLA
this gives me an output of 20070511 23:06:30:000
the space in MM : SS is intentional here, since without that space it appread as smiley
I'm trying to map this to datetime field in sql server 2005. It keeps failing with this error
The value could not be converted because of a potential loss of data
I'm struck with error for hours now. Any pointers would be helpful.
I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField from MyOptions where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField from MyTimetable where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.
I'm trying to put a date into a SQL Server table. The database field type is "smalldatetime". The variable dDate is type "date" and contains: 2/2/2006 (although I think Cdate actually converts it to: #2/2/2006#). When I run the following code the date in the database is always ends up being: 1/1/1900. Dim cmd As SqlCommand = New SqlCommand("INSERT INTO MyTable(MyDate) " & _ "VALUES (" & dDate & ")", SqlConn)daAppts.InsertCommand = cmddaAppts.InsertCommand.Connection = SqlConndaAppts.InsertCommand.ExecuteNonQuery() Any other field types work fine, it's just dates that aren't working ???? Can someone please provide a code snippet showing me what I'm doing wrong??
I have a smalldatetime column. When I did SELECT * INTO MY_TABLE FROM YOUR_TABLE WHERE CONVERT(VARCHAR(12), DATE_ENTERED, 101) > '01/01/2001' rows from 1998, 1999 came over.
I have two columns in a table:StartDate DateTime and StartTime DateTime.The StartDate column holds a value such as 07/16/2004The StartTime column holds a value such as 3:00:00 PMI want to be able to add them in a stored procedure.When I use StartDate + StartTime I get a date two days earlier than expected.For example, instead of 7/16/2004 3:00:00 PM StartDate + StartTime returns7/14/2004 3:00:00 PM.Can anyone point out wht I'm doing wrong with this one?Thanks,lq
Hi there. I'm trying to extract data from my SQL server & everything in the script I've got is working (extracting correct data) except for one field - which is for the most part it's off by +2 days (on a few occasions - I see it off by just +1 day or even +3, but it's usually the +2 days).
I'm told that it's due to the conversion formula - but - since SQL is not my native language, I'm at a bit of a loss.
The DB table has the date field stored as a type: CHAR (as opposed to 'DATE') Can anyone out there help?
A server with SQL 2005 sp2, Reporting Services and Sharepoint services (ver 3.0) (in integrated mode) gives an odd error. When viewing a Reporting Services report with a Date Time Picker, the date chosen is wrong. The preferred setting is Danish with the date format dd-mm-yyyy. The date picker shows the months in Danish but when selecting a date, and clicking on the Apply-button, the date reformats to US (mm-dd-yyyy).
Example: When choosing 5th of September 2007 and clicking apply, it shows in the picker, 9th of May 2007. When choosing 26th of September 2007 and clicking apply, it shows, again in US format, the RIGHT date but adds a timestamp 12:00 AM? in the end, making further enquiries to fail.
The report itself receives the right date and shows correctly. The only case it fails is, when the time stamp appears.
The server is a 32-bit one with 4 GB RAM. A testserver with identical collation on the Reportserver database cannot recreate the error. The site containing the reports has been set to Danish in the regional settings. To Reinstall is not an option.
The test report has no database connection whatsoever.
When setting the site to US, the timestamp wont appear at all.
The server has been restarted and the installation procedure was of the simple kind. No special tweaks at all.
How can I obtain just the time portion from a date/time column? My data contains "2008-05-19 09:30:00.000" Actually, all I want/need is the hh:mm part of it.
I have passed createdDate from UI to Stored procedure.createdDate field declared with DateTime.it is having value 2014-07-01.I need to fetch records from the database based upon the created field.but Create_TM in database having value Date with timestamp.so how would i change the createdfield in stored procedure.
ALTER PROCEDURE [dbo].[ByDateRange]
@Feed VARCHAR(50),
@CreatedDate DATETIME
select * from Date_table where Create_TM = @CreatedDate
I have a table named "shift" and I need to setup my query to return only data where the field "startime" = today. The problem I am running into is the starttime field it laid out like "2005-12-29 14:00:00" with different time values. I need to ruturn everything that has todays date regardless of the time value. I tried using GetDate() but that is returning data for other days as well or just data before or after the current time. Does anyone have any suggestions? This is driving me crazy! Thanks, Garrett
Hi,I need a way of changing the following SQL statement so that the dates are without the hh:mm:ss tt:"Select DISTINCT([StartDate]) From [Events]"How can this be done?Thanks,Curt.
I have a table in which a date value is stored as varchar.some of these values are stored ina dd/mm/yyyy format and other values are stored in a yyyy-mm-dd format..Now I wish to retrieve some data by querying between two dates. However I need to convert the varchar date value to datetime in order to do this but since the date value is in two different formats, the following doesn't work.
select date_value from my_table where CONVERT(DATETIME, date_value, 103) between @date1 and @date2
How can you convert the date value to datetime when its stored in mutiple formats. I can't change the table itself as I dont have admin privelages.
I am using the calender parameter and I need to convert my data date format to the one that matched that is returned on selecting a date from this calender. Can you show me what this format is.
how can I convert my existing date format to this format. The existing date format is 2007-07-26 21:27:13.000
I want to compare two columns in the same table called start date and end date for one clientId.if clientId is having continuous refenceid and sartdate and enddate of reference that I don't need any caseopendate but if clientID has new reference id and it's start date is not continuous to its previous reference id then I need to set that start date as caseopendate.
INSERT INTO [GPO].dbo.tblMetric (KPI_ID, METRIC_ID, GOAL, REPORTING_MONTH, ACTUALS) SELECT

The insert column I am trying to get into is a date type. The original state of the field is YYYYMM varchar. How to get this into the table.
I have a table here. I want find a way of getting the latest date, when the code is the same. If the Declined date is null. Then I still want the latest date. E.g. ID 3.
If the declined date is filled in. Then I want to get the row, when the Datein column value is greater then the declined date only.
I tried grouping it by max date, but i got an error message when trying this out. Against the code
WHERE MAX(Datein) > Declined
An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or a select list, and the column being aggregated is an outer reference. What do I need to do to get both my outputs working?
So my data column [EODPosting].[MatchDate] is defined as a DATE column. I am trying to SELECT from my table where [EODPosting].[MatchDate] is today's date.
Is this not working because GETDATE() is like a timestamp format? How can I get this to work to return those rows where [EODPosting].[MatchDate] is equal to today's date?
as you can see, the records have a 30minutes time interval. i need to create a query to know if there are missing records in the table. so basically the result should be this:
