Hello.
What I'd like to ask is if there is a way to configure SQL Server 2005 to use only a certain amount of RAM. I have a machine with 4GB RAM, and there are a lot of apps running on it. It is when SQL Server starts executing a query over a relatively large database (e.g. 20 - 30 GB)that things go bad for all other apps - SQL Server uses almost all of the available RAM, leaving only a very limited amount for all other applications to use.
Any suggestions?

Those are fairly large databases and depending on your queries you could be hitting the processor heavily - as you are discovering.
The only solution I can think of is to remove all those extra applications.
Good practise dictates that your SQL Server is a machine that is primarily a dedicated server i.e you have no other applications on it (other than an email client, backup application etc)
If you are using databases of the size you mention I suggest you get another machine on which to run the other applications.
Some more tips:
Keep your databases and transaction logs on separate disks.
Make sure that your applications are not on either of these disks.
I know this doesn't answer you question directly...
You always pass failure on the way to success.

You cannot explicitly set the amount of RAM that the system should use (as far as my little knowledge serves me). You can however, set the priority of the SQL Server to low as compared to other applications (Press ALT+CTRL+DEL > Click task Manager > Applications (TAB) > Select Image Name sqlmangr.exe > Right click on it and select option: set priority). That would mean that you would have more processing preference for other applications. But remember, with the size of the databases you are talking about, you would still have issues with the processor getting hit hard. If you cannot redice the DB size, then increase the RAM, much better get dual processors and set one processor to solely work on SQL Server. This is what a Hardware guy can set for you.
Regards.

Open up Management Studio, connect to your server. In Object Explorer, right click on the Server Root and select "Properties". Under the "Memory" page, enter a value in the "Maximum Server Memory" textbox.
The change will take effect when SQL Server is under lesser load and can shed some memory or when you restart the service.

I am using the Query Builder in Visual Studio to fill my Dataset but one of the field/column names is unknown until runtime; therefore I wish to specify this on the fly.
My current query is as follows:
SELECT Cards.Id, Cards.Card, Cards.FirstName, Cards.LastName, Cards.AccessLevel, Cards.StartDate, Cards.EndDate, Cards.fTitle, ?,<br />
Photo.Id AS Expr1, Photo.Photo,<br />
AccLevel.AccessLevel AS Expr2, AccLevel.Name AS AccessName<br />
<br />
FROM (Cards<br />
LEFT JOIN Photo ON<br />
Cards.Card = Photo.Id)<br />
LEFT JOIN AccLevel ON<br />
Cards.AccessLevel = AccLevel.AccessLevel
The question mark represents a variable field name. Below is the code which fills the dataset by calling the query above - although for now, I have passed it a fixed string which represents one of the fields in the ‘Cards’ table and should replace the question mark in the query:
cards_Photo_AccessLevelTableAdapter.Fill(MyDataSet.Cards_Photo_AccessLevel, "Cards.fDepartment");
Although my code builds ok, an exception is caused when the Dataset is filled as above.
Any help would be much appreciated!!
Regards,
Christian

A datetime field stores a whole date and time. You can't store just a time.
There are functions in T-SQL for extracting time-specific information from a datetime value.

Hey,
Unfortunately you cannot save the dateTime column without date. However you can extract them using the convert function in SQl Server.
e.g:
select convert(varchar,DateColumn,108) from MyDateTest99
The following table gives you the details of which digit sequence to use:
0 or 100 mon dd yyyy hh:miAM (or PM)
101 mm/dd/yy
102 yy.mm.dd
103 dd/mm/yy
104 dd.mm.yy
105 dd-mm-yy
106 dd mon yy
107 Mon dd, yy
108 hh:mm:ss
9 or 109 mon dd yyyy hh:mi:ss:mmmAM (or PM)
110 mm-dd-yy
111 yy/mm/dd
112 yymmdd
13 or 113 dd mon yyyy hh:mm:ss:mmm(24h)
114 hh:mi:ss:mmm(24h)
20 or 120 yyyy-mm-dd hh:mi:ss(24h)
21 or 121 yyyy-mm-dd hh:mi:ss.mmm(24h)
126 yyyy-mm-dd Thh:mm:ss.mmm(no spaces)
130 dd mon yyyy hh:mi:ss:mmmAM
131 dd/mm/yy hh:mi:ss:mmmAM
Hope that this helps...

Ali

hi there,
i m trying to retrieve data from one table with 2 condition in 2 queries, here is an example
select id, count(Number) from myTable where Number < 10 group by id order by id
select id, count(Number) from myTable where Number >= 77 and Number <=100 group by id order by id
the result is coming what expected but i want to run only single query for single result
for example
the result is coming :
QUERY 1
ID----(Column Name)
10----66
14----3
19----44
30----22
QUERY 2
ID----(Column Name)
30----45
40----74
55----43
60----44
what i want :
ID----(Column Name)----(Column Name)
10------66--------------0
14------3---------------0
19------44--------------0
30------22--------------45
40------0---------------74
55------0---------------43

Cool.
There may be a better way to do this, but here's what I'd do. In the old world you could create a view to represent each query and then join them together, but you can use Common Table Expressions in 2005 (http://msdn2.microsoft.com/en-us/library/ms190766.aspx[^]) which are similar.
So, create the two queries as you have them with the with keyword. Then to combine the two results set you want a full outer join with an isnull to check for null ids resulting from the join and to set nulls to zeros on the count.
Does that make sense?

Rob Philpott.

SELECT Dat
FROM dbo.tblkmreading
WHERE DAT = GETDATE()
i have records pertaining to current date , the above query is not fetching the records.Please rectify it
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Thie GETDATE() Function returns the time now ie: 3/30/2008 12.35.05...
You will need to parse the GETDATE() result to return just MM/DD/YYYY and use his in your WHERE clause.

select dat from tblkmreading where dat = convert(varchar(10) , getdate() , 103)
still getting the following error
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
dat is a datetime type
this is the another way i did , but no record is comming
select dat from tblkmreading where dat = convert(datetime , getdate() , 103)
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Is the data stored as DateTime dataType in the database? You cant expect that your query will run at the exact time that a record is written.
In this case you may have to change your Where clause to BETWEEN and look from 12:00:00am to 11:59:00pm. Or Between 3/31/2002 12:00:00 And 4/1/2008 12:00:00
Sorry, I dont have a query editor handy to check this out 
DECLARE @Start DateTime
SET @Start = '3/31/2008'
DECLARE @End DateTime
SET @End = '4/1/2008'
SELECT [Date] FROM TestData
Where [Date] Between @Start and @End
I don't speak Idiot - please talk slowly and clearly

Try this
declare @Now datetime
select @Now = convert(varchar,getdate(),103)
SELECT Dat
FROM dbo.tblkmreading
WHERE DAT >= @Now
I suspect your Dat column contains a time as well as a date. The above code trims off the time from getdate.

dat is of datetime type
still occuring the error
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.

What version of SQL Server are you using? My code works fine with 2000 and 2005.

If Dat is date time format in your table then use following query
SELECT Dat
FROM dbo.tblkmreading
WHERE convert(varchar,Dat,103) = convert(varchar,GETDATE(),103)
If Dat is varchar in your table then use following query
SELECT Dat
FROM dbo.tblkmreading
WHERE convert(varchar,convert(datetime,Dat),103) = convert(varchar,GETDATE(),103)
