Time Delay In SQL Server 2000 For Date Variable

Nov 6, 2002

Hello I have and tested in 2 way using variable and constant.
Query 1: This query I am using vaiable "@last" for the date value.
this takes to run for 2 minute .

Query 2: Here I am using value '11/05/2002' instead of varialbe and it is running within a second.

Why these much difference to run this same query?.
Can anybody give correct reason or solution for this.
Thanks,
Ravi

query 1:
DECLARE @last smalldatetime
SET @last ='11/05/2002'

select distinct(o.account_num),a.enterprise_num,a.site_nu m
from oesd.dbo.order_header o WITH(NOLOCK)
INNER JOIN oesd.dbo.account a WITH(NOLOCK)
ON a.account_num = o.account_num
and o.added_date > @last
UNION
select distinct(o.account_num),a.enterprise_num,a.site_nu m
from oesd.dbo.order_header o WITH(NOLOCK)
INNER JOIN oesd.dbo.account a WITH(NOLOCK)
ON a.account_num = o.account_num
INNER JOIN Leap.dbo.ENTERPRISE_STATE es WITH(NOLOCK)
ON (a.enterprise_num = es.ENTERPRISE_NUM
AND o.last_updated_date > @last)


Query 2:

select distinct(o.account_num),a.enterprise_num,a.site_nu m
from oesd.dbo.order_header o WITH(NOLOCK)
INNER JOIN oesd.dbo.account a WITH(NOLOCK)

Conversion Of Oracle Date Time To Sql Server Date Time In SSIS

Jun 30, 2007

This is driving me nuts..



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.



Thanks

SQL Server 2008 :: Loop Through Date Time Records To Find A Match From Multiple Other Date Time Records?

Aug 5, 2015

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.

Splitting SQL Server Date/Time Column Into Access Date Column And Access Time Column

Jan 24, 2008

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?

Thanks,

Steve

Date/time Problem In SQL Server 7.0

Jun 2, 1999

Hi folks,
I posted the following question on comp.databases.ms-sqlserver,
bu, to my surprise got no responses. So I wondered if you good
people might be able to help us out...
==================================================
Our application communicates with SQLServer 7 through ODBC. In
order to write date/time fields into the database, it uses either the dt
conversion function, or more usually the ts conversion, on a string of
the format 'yyyy-mm-dd hh:mm:ss.xxxxxx'. With almost every every
other database engine (I think Informix is the only exception), this is
accepted and converted into a date format that the back end can store.

With SQLServer 7, any inserts containing dates are dropped because the
timestamp conversion isn't working. If I take a copy of the select statement
into the query analyser, it reports an error unless I change the timestamp
string format from ts 'yyyy-mm-dd hh:mm:ss.xxxxxx' to ts 'yyyy-mm-dd
hh:mm:ss.xxx', ie from microsecond to millisecond resolution.

Version 6.5 didn't have this problem, and as I mentioned, nor does any other
database engine that our application talks to.
================================================== ===

Anyone any ideas???

Cheers,
Geoff.

Integration Services :: Exclude Time In Date Time Variable In SSIS For Loop?

Oct 22, 2015

I am trying to load previous days data at 3 am via a SSIS job.

The Date variable is initiated as DATEADD("dd",-1, GETDATE()) in the for loop.

Now, as this job runs at 3 am, and I set the variable as GETDATE() - 1, it excluded the data from 12 am to 3 am in the resultset as Date is set as YYYY-MM-DD 03:00:00:000 I need this to be set as YYYY-MM-DD 00:00:00:000

How can i do this?

Inserting The Current Date And Time Into SQL Server Database

Mar 30, 2007

I need an SQL string that inserts the current date into a database.
So far I have tried:
SQL = "INSERT INTO X (START_DATE) VALUES ('" & Date.Now & "')"
mycomm = New SqlCommand(sql, myconn)
mycomm.ExecuteNonQuery()
However, there is a problem with the SQL command. The problem is related to the date. Is there a way of programatically inserting the current date/time into the SQL database? Language used is VB.

Date And Time Best Practice - Storage In SQL Server Database

Jul 27, 2007

With regards to time zones, daylight savings, and web users, is there a best practice for storing date & time information in a database?
For example, my databases are hosted in Time Zone A, but the web users are in Time Zone B.  Then, when I create a rss feed (which is displayed in GMT), I add a third time zone into the mix for the same data.  To date (no pun intended), I have been entering the date/time data in the time zone of the database server (Time Zone A), and then converting it using an application setting in the web.config file (i.e. TimeZoneBOffset = -1, GMTOffSet = -5).  In other words, each time I display a date I calculate what it should be using the time-zone offset in the web.config.  This also enables me to account for changes in day light savings, etc.
My concerns are three fold:  1. What if I move the database to another server and the time zone changes?  2. Right now the users are in only 1 time zone.  If I expand it to several then the offset will have to be by users, which is do-able, but something I haven't had experience with in the past.  3. It is likely more efficient to calculate the time zone once on input into the DB, rather than in each use like I'm doing now.  What time zone baseline for insert into the db should I use?
Thanks in advance for your help!
PS My application is primarily looking at 'smalldatetime' data - down to the 'minute' level.

Sql Server 2005 Add Current Time To The Passed Date

Jun 2, 2008

 Greetings,I have an e-timesheet application.i made a function that takes the startdate of the week:public SqlDataReader GetProjectsActive(DateTime SheetDate)         {            SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings["connectionString"]);            SqlCommand myCommand = new SqlCommand("GetProjectsActive", myConnection);            myCommand.CommandType = CommandType.StoredProcedure;            SqlParameter parameterSheetDate = new SqlParameter("@SheetDate", SqlDbType.DateTime);            parameterSheetDate.Value = SheetDate;            myCommand.Parameters.Add(parameterSheetDate);            myConnection.Open();            SqlDataReader dr = myCommand.ExecuteReader(CommandBehavior.CloseConnection);            return dr;        } i run the application and i pass the value 6/1/2008 (date without time) to the GetProjectsActive but what i notice that the storedprocedure adds the current time to the passsed date when it has been executed so some projects will not  appear since the startdate and enddate of the project are only dates so i try this solution: parameterSheetDate.Value = SheetDate.Date;and it works finebut my question why the current time has been added to the storedprocedure automatically although i pass only the date 6/1/2008 date????your help is highly appreciated.Best regards.

Force SQL Server To Recompile Stored Procedures Every Time They Run (SQL Server 7/2000)

Apr 27, 2005

This is a solution for a very specific problem, and it's one that you'll hardly ever use, but it's important to know about that one scenario where it can save your neck. Ordinarily, stored procedures are only recompiled if they're no longer in the procedure cache. But if a stored procedure's execution plan is still in the cache, then SQL Server reuses the compiled storedprocedure and its existing execution plan. This is almost always the best course of action. Almost always, but not always.Sometimes, however, reusing an existing plan doesn't offer the most efficient performance. Imagine, for example, that your stored procedure accepts a parameter that determines the natureof a JOIN operation. The results can vary in a big way, so you wouldn't want your procedure to be locked into an execution plan that might be completely inappropriate for that JOIN. In a highlyspecialized case like this, you might want to force SQL Server to recompile the procedure every time the procedure runs. Doing so comes at a performance cost, but this might be offset by thesavings you gain in not executing the procedure with an awful compiled execution plan. Consider carefully whether to use this approach (or whether to re-engineer the over-design of yourapplication to avoid this situation in the first place). Should you need to instruct SQL Server to recompile each time, add the WITH RECOMPILE directive to the procedure, like this:    CREATE PROCEDURE ProcName        @Param int /* ... other parameters */        WITH RECOMPILE    AS /* ... procedure code follows */
If we omit "WITH RECOMPILE", what will be the consequence? Thanks

SQL Server 2012 :: Increment Date Based On Time Value Automatically

Jul 1, 2015

I have a client data which has the candidate id, a start date which will have only the date in varchar format and a time value associated to that date in varchar format in a seperate column.

To give a brief explanation about the data a candidate will come to study center at any time point in a day for example 10:00 AM on 20-10-2014. The start date will be 20-10-2014 and from 10:00 AM he will have test based on the time point. So if the time point is 2 HR, then at 12:00 PM he will have a test. If the time point is 8 HR, it will get added with 10:00 AM and based on this he will have the test at 06:00 PM. When the timepoint reaches 00:00 the start date needs to be the next date instead of 20-10-2014.

The start date needs to be appended with the time value such that when it crosses over the time 00:00, the start date needs to get increased by 1 ie the next day. I have added the start date to the time by using the code below

CAST(STARTDATE as datetime) + CAST(CAST(STUFF([TIME],3,0,':') as time(0)) as datetime) as [EXPECTEDDATETIME]

By this above code i have created the expected datetime however

I will not be able to hardcode the value due to dynamic data. I tried to apply >= and < to the time value something like

case when MyTime >= '00:00' and MyTime < '08:10' the Dateadd(day, 1, date)

This works perfect but my concern is that I cannot put the value 08:10 because it will not a constant value for all rows.

I have provided a screenshot of my data and a expected date column for reference.

Candidate StartDateStartTimeExpected DateTime Timepoint
1 20141020 1000 2014-10-20 10:00:00 0 HR
1 201410201200 2014-10-20 12:00:00 02 HR
1 201410201400 2014-10-20 14:00:00 04 HR
1 201410201800 2014-10-20 18:00:00 08 HR
1 201410200000 2014-10-21 00:00:00 12 HR
1 201410201200 2014-10-21 12:00:00 24 HR
2 20141020 1100 2014-10-20 11:00:00 0 HR

SQL Server Admin 2014 :: Concatenate Random Date And Time

Oct 20, 2015

I've used some info on here to generate random dates within a given range and also random times - independently they work fine, but I can't seem to join them into a single field of datetime. I'm not sure why. The following snippet works fine as two independent fields:

select CAST(CAST(ABS(CHECKSUM(NEWID()))%(780)+(33968) AS DATETIME) as DATE) as theDate,
CAST(CAST(DATEADD(milliSECOND,ABS(CHECKSUM(NEWID()))%86400000 ,'00:00') AS TIME) as varchar(50)) as theTimeBut when I try to make it a single datetime field:

select CAST(cast(cast(CAST(ABS(CHECKSUM(NEWID()))%(780)+(33968) AS DATETIME) as date) as varchar(50)) + ' ' + cast(CAST(CAST(DATEADD(milliSECOND,ABS(CHECKSUM(NEWID()))%86400000 ,'00:00') AS TIME) as varchar(50)) as varchar(50)) as datetime)

Which returns with: Conversion failed when converting date and/or time from character string.

So what I am really looking for is a way to join those two values into a single datetime field... Or failing that that how to generate random dates within a range including random times...

Date/Time Of Latest SQL Server 2005 Instance Restart

Jan 28, 2008



Is the Date/Time of the latest SQL Server 2005 instance restart stored somewhere in the system catalog?
This value is quite relevant when retrieving information on the costliest unused indexes in the instance.

I know of one way of doing this, which is to search the SQL Logs for this info.
This solution is very unwieldy - we recycle the logs daily and we only keep the logs of the last 7 days.

Changing Database Server Locale Date Time Settings ?

Jun 15, 2007

Hi There



We currently have the following scenario:

4 app servers with regional date and time settings of locale A.

1 database server with locale settings B.



What is happening is that timestamps are being generated on the app servers, these are then in a sql command which fails on the database server since the timestamp format is invalid.



It was suggested that we change the regional locale settings of the database server, but will this not have serious implications , for example every current timestamp format in the datbase will become invalid?



In a nutshell is it safe to change a database servers regional date time locale settings ? Or are there serious implications?



Thanx
