Arbitrary Dates

Mar 30, 2006

How can I select all the "filler" dates.


CREATE TABLE tbDateList
( ItemDate datetime )

INSERT INTO tbDateList (ItemDate)
SELECT '01/01/2006' UNION ALL
SELECT '01/10/2006'

SELECT * FROM tbDateList
DROP TABLE tbDateList


In the select statement, I want to select all dates in tbDateList, but I also want to include dates that are not in the list.

Eg: the above select * will return the 2 dates, but I want it to return the 10 dates, 01/01/2006 - '01/10/2006'

Any suggestions?

Querying Table In Arbitrary Database

May 1, 2006

Would appreciate some help with this one. I need to run a query on a known table an arbitrary database. The DB name will be selected at runtime.

What I've tried:

DECLARE @DBName varchar(10)
SET @DBName = 'WBTST'

SELECT TOP 100 PERCENT Col1, Col2
FROM [@DBName].dbo.Table1
GROUP BY Col1

Result:
Invalid object name '@DBName.dbo.UPR00100'.

I've also tried without the square brackets around @DBName in the FROM clause. This results in: Incorrect syntax near '.'.

Thanks for the help
Wes

Performance Tuning For Selecting Arbitrary Range

Mar 22, 2007

I have two tables:

Headers(id int, time datetime)

Data(id int, product_id int, property_id int, value float)

Data.id references Headers.id

Headers.id is a primary key,
Data has clustered index (id, product_id, property_id)

Headers has several thousand rows, Data several million. I want to return all rows from Data for a given product_id and a given property_id such that Header.id is in a given range.

Right now I am doing

SELECT id, time, value
FROM Headers H, Data D
WHERE
H.id = D.id AND
H.time >= @StartTime AND
H.time <= @EndTime AND
D.product_id = @ProductID AND
d.property_id = @PropertyID

This query can take 10+ seconds to run, though once I run it for a given product_id, queries for different values of property_id are much faster. Try a different product_id, and it takes longer. Given that there are millions of records in Data, is it reasonable for it to take this long? The index was suggested by Query Analyzer's Index Tuning Wizard, and I tried a couple variations on the query without any noticeable performance improvement. But, I'm no DBA...anyone have any tips? I googled a bit but couldn't figure out the right way to phrase my question to find any good info...thanks in advance

How To Tailor CREATE DATABASE For An Arbitrary Instance

Sep 20, 2006

Suppose the following:

As part of a product install (using InstallShield)...

I create a SQL Server Express instance (say "X") via a silent install
I supply a script to create a database in instance X.

The idea, of course, is to have a fully automated install. But there's one problem I can't quite see how to work around:

- the CREATE DATABASE statement needs the name of a file to contain the database, and that file needs to be in a folder that belongs to the instance (e.g. Microsoft SQL ServerMSSQL.1, Microsoft SQL ServerMSSQL.2, etc).

Is there a syntactic variant that allows me to avoid this problem?

Thanks
Josh

Generate Dates Between Two Dates

Nov 8, 2006

Hi,

I have a table which records employees'time-off records. There are 6 columns in this TimeOff table. They are RequestID, EmpName, StartDate, EndDate, Type, NumofDays. I have another table which has all the dates from 01/01/1950 to 01/01/2056.

I am trying write a query which lists all the dates between the timeoff startdate and enddate, including the the start and end dates, but my query so far only lists the start and end date in a timeoff record:

SELECT D.[Date], Datename(dw,D.[Date]) AS Weekday
FROM Dates D LEFT JOIN TimeOff T ON D.[Date] = T.OffStartDate OR D.[Date] = T.OffEndDate
WHERE (OffType = 'Sick Day' AND EmpName = 'Cat White') AND (D.[Date] BETWEEN T.StartDate AND T.EndDate)

Any advice will be greatly appreciated!

Getting Individual Dates Between 2 Dates

Mar 4, 2008

Has anyone ever written a function to retrieve all individual dates between two given dates? Using DATEDIFF I can get the number of days between two dates. However I need to iterate through the days to identify weekend and holiday dates. Has anyone ever written a function to do this?

So, if select datediff(d,'07/01/2007','07/15/2007') as NumOfDays returns 14, I'd need to iterate through the 14 days and get the weekends and holidays. Would I have to use a cursor to iterate through the days?

Jan 10, 2002

Hi can anyone help me , or am I on the wrong track.

Is there any easy way to create a stored procedure that inserts into a table the relevant months dates into a table based on the month and year as parameters.
I.e say the parameters passed are 01/2001 hence based on this all of the month of January 2001 dates are inserted into a table in this format : 'Jan 01 2001 12:00:00'

SQL Dates

Apr 19, 2004

OK, so I can return (& therefore use) the last day of last month using

select (GETDATE()- DATEPART ( dd , GETDATE()))

Which returns 31-03-2004 (dd-mm-yyyy)

Has anyone a good way of determining a way of deriving say a date such as 01-01-2004 (1st Jan)....

I'd like to get some data where my dmd.sdate falls always in the previous quarter.. but would like it to be not hard coded...

Currently I have

SELECT cust.no,
cust.surname,
dmd.csan,
dmd.sdate
FROM pdunity.dbo.cust cust,
pdunity.dbo.dmd dmd
WHERE cust.rowno = dmd.rowno_custdmd_cust
AND(dmd.sdate
BETWEEN '01/01/2004'
AND(GETDATE()- DATEPART ( dd , GETDATE())))
ORDER by dmd.sdate asc

Is there some form of function I can use to return 01/01/2004 automatically ?

Dates Between 2 Other Dates

Aug 16, 2002

Hi All

I have a table which contains apart from other fields, 2 dates. i.e. startdate and enddate.

The startdate is always less than / equal to enddate.

I want to write a stored proc where I will give a date as a parameter and it should give me all the records there my date is between the startdate and the enddate.

Also I want to create a temp table in the procedure and the table gets populated with all the dates that comes between startdate and enddate, both dates inclusive.

I know this might be a tall order, but I am new to writing stored procedure, so I will be obliged if somebody can help me out

ISO Dates?

Jul 20, 2005

To support an application, I am integrating it with with Sqlserver2000. The task is simple: get the data at regular intervals, andwrite it into a table dedicated for that application. One of thefields I receive is a date, and it is formatted as an ISO date. Asample value looks like this: "2004-07-09-15.37.52.077258".SQLServer doesn't support this date format, though. The closest Ihave found is the style code "21" or "121" which accepts input as"yyyy-mm-dd hh:mi:ss.mmm". I have looked at using several replace()and convert() calls but no solution yet.Is there a way to transform the data to conform to this style acceptedby Sqlserver? I would like to do this in the INSERT statement itselfand not have to code application logic (i.e., user-defined function,etc.) for it.

Get Dates NOT Between X And Y

Jul 27, 2006

Hi. I hope this is the write place to post this, I hope it is.



basically, I want to be able to return me a query of giving me available dates in a table.

What I mean is that, if I have a table with fields including start date and end date, I want to return me the dates which are NOT listed/stored in the table.



kind of like a booking system, where you store the room reservation dates and obviously you don't want to double book that room, so I would like all the available dates to be returned back.



is this possible? how can I go about doing this?



Thanks!

Hi,

I have date columns in my tables defined as smalldatetime. How do I perform a Select that will retrieve records with dates equal to the date selected in a calendar control as follows:

<asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:ReservationsConnectionString %>"

SelectCommand="SELECT [TIM_Time], [TIM_ID], [TIM_Valid_From] FROM [Times] WHERE ([TIM_Time] = @TIM_Time)">

<SelectParameters>

<asp:ControlParameter ControlID="Calendar1" Name="TIM_Time" PropertyName="SelectedDate"

Type="DateTime" />

</SelectParameters>

I get no records when I know they are there - do I have to put in additional checks to cater for the time component of the column?

Thanks in advance.
