Hello
How to check a value IS NULL [or] = @param (where @param is null)
Ex:
Select column1 from Table1
where column2 IS NULL => works fine
If I want to replace comparing value (IS NULL) with @param. How can this be done
Select column1 from Table1
where column2 = @param => this works fine until @param got some value in it and if is null never finds a record.
How can this achieve?
I am reasonably good at dealing with SQLServer clusters; I am wondering if folks have experience, good or bad, using a mix of different models of servers from the same vendor in one SQL 2005 cluster.
Suppose:
I have one more powerful, more RAM, more shizzle box and one less powerful, less memory, less shizzle box bound together in a 2-node cluster. These would be HP DL380 and 580 machines (not that it should matter)
I understand AND automate the process of managing memory for each SQL instance, so there's no memory contention when SQL instances fail over. Basically I am thinking a CLR proc will monitor the instances and self-regulate memory caps on each instance, so that they won't page or step on one another.
I get the fact the instances might be slower and or under memory pressure if they share a "lesser" node, and that's OK. The business can deal with a slower instance in a server-problem scenario.
Reasonable? Any "gotchas" to watch out for?
More info 10/28: doing some experiments with a test cluster I find that reconfiguring max/min memory is OK PROVIDED the instance isn't already under memory pressure. If I torture the system with a huge query that demands a big chunk of RAM, and simultaneously adjust the memory allocation to a smaller value than what is being actively used, it's possible to run the instance out of memory and have it halt and restart itself (unhappy situation). Many ugly out-of-memory messages in the error log, crashing, burning... It's an extreme case, but good to know.
Seems, then, that it would only be really safe to set this on startup of the instance, as in have a startup script that says "I am on node1, so my RAM settings are X or I am on node two, so they are Y," like this:

Update: I am testing a SQL Agent + PowerShell solution described in more detail here.
Hey,everyone
I have a string 'some.file.name',I want to grab 'some.file'.
To do that,I need to find the last occurrence of '.' in a string.
My solution is :
declare @someStr varchar(20)
declare @reversedStr varchar(20)
declare @index int
set @someStr = '001.002.003'
set @reversedStr = reverse(@someStr)
set @index = len(@someStr) - charindex('.',@reversedStr)
select left(@someStr,@index)
Well,isn't it too complicated?I was just intented to using 'some.file' in a where-clause.
Anyone has a good idea?
I would like to use newId to generate random numbers. Usually you would use it just once, but I might be generating up to 10 random numbers per newId.
Is it random enough?
i've created a function for convert minutes (smallint) in time (varchar(5))
like 58 - 00:58
set QUOTED_IDENTIFIER ON
GO
Create FUNCTION [dbo].[IntToMinutes]
(
@m smallint
)
RETURNS nvarchar(5)
AS
BEGIN
DECLARE @c nvarchar(5)
SET @c = CAST((@m / 60) as varchar(2)) + ':' + CAST((@m % 60) as varchar(2))
RETURN @c
END
The problem is when there are minutes < 10 in time
like 9
the result of this function is 0:9
i want that the format is 00:09
how can i do that?
I have a TimeSheet table as:
CREATE TABLE TimeSheet
(
timeSheetID
employeeID
setDate
timeIn
outToLunch
returnFromLunch
timeOut
);
Employee will set his/her time sheet daily, i want to ensure that he/she doesn't cheat. What should i do?
Should i create a column that gets date/time of the system when insertion/update happens to the table and then compare the created date/time with the time employee's specified - If so in this case i will have to create date/time column for timeIn, outToLunch, returnFromLunch and timeOut. I don't know, what do you suggest?
Note: i'm concerned about tracking these 4 columns timeIn, outToLunch, returnFromLunch and timeOut

I have a large historical transaction table (15-20 million rows MANY columns) and a table with one row one column. The table with one row contains a date (last processing date) which will be used to pull the data in the trasaction table ('process_date').
Question: Should I inner join the 'process_date' table to the transaction table or the transaction table to the 'process_date' table?
I have written the below SP for Precheck for Duplicate records before insert into Table .
but it is not allow me yo write insert staement inside the CASE .
how can I write Stored Procedure for fist Check the value @Ordername into table After that if it is not present then it should inserted into Database .
CREATE PROCEDURE [Test Procedure ]

when (select OrderName from dbo.tbl_insertxmldetails
where(@OrderName) not in (select OrderName from tbl_insertxmldetails))
then
insert into dbo.tbl_insertxmldetails
(Section, Mark, QTY,Weight,Dateupdateremark ,OrderName,SystemDate)
values
(@Section, @Mark, @QTY,@Weight, @Dateupdateremark,@OrderName,GETDATE())
else 'File already Exists'
end
I have the below

DDL is as under
DECLARE @t TABLE(PersonName VARCHAR(32), [Date] DATETIME)
INSERT INTO @t VALUES('A', '2011-01-01 01:00:00')
INSERT INTO @t VALUES('A', '2011-01-02 02:00:00')
INSERT INTO @t VALUES('A', '2011-01-03 03:00:00')
INSERT INTO @t VALUES('B', '2011-01-04 04:00:00')
INSERT INTO @t VALUES('A', '2011-01-05 07:00:00')
Select * from @t
select @[email protected]('*')
for xml raw,type
Above statement will generate following alert:

The FOR XML clause is not allowed in a ASSIGNMENT statement.
Hi
I am wondering how can do a mass insert and bulk copy at the same time? I have 2 tables that should be affect by the bulk copy as they both depend on each other.
So I want it that if while inserting table 1 a record dies it gets rolled back and table 2 never gets updated. Also if table 1 inserts good and table 2 an update fails table 1 gets rolled back.
Can this be done with bulk copy?
hi all,
I have a db with users that have all this record .
I would like to do a query on a data like
CN=aaa, OU=Domain,OU=User, OU=bbbbbb,OU=Department, OU=cccc, OU=AUTO, DC=dddddd, DC=com
and I need to group all users by the same ou=department.
How can I do the select with the substring to search a department??
My idea for the solution is to create another table that is like this:
---------------------------------------------------
ldapstring | society | site
---------------------------------------------------
"CN=aaa, OU=Domain,OU=User, OU=bbbbbb,OU=Department, OU=cccc, OU=AUTO, DC=dddddd, DC=com" | societyName1 | societySite1
and my idea is to compare the string with these on the new table with the tag like but how can I take the society and site when the like string occurs?????
Please help me
I would like to create a stored procedure that takes in a string of comma separated values like this "1,2,3,4", and break it apart and use those numbers to run a query on a different table.
so in the same stored procedure it would do something like
select somefield from sometable where somefield = 1
select somefield from sometable where somefield = 2
select somefield from sometable where somefield = 3
select somefield from sometable where somefield = 4
Thanks!
for eg...
SELECT *
FROM ( SELECT RANK() OVER (ORDER BY stud_mark DESC) AS ranking,
stud_id,
stud_name,
stud_mark
FROM tbl_student ) AS foo
WHERE ranking = 10
Here foo is present...actually what it does ?..
I've banging my head for hours, it seems simple enough, but here goes:
I'd like to create a view using multiple select statements that outputs a Single record-set
Example:
CREATE VIEW dbo.TestDB
AS
SELECT X AS 'First'
FROM The_Table
WHERE The_Value = 'y'
SELECT X AS 'Second'
FROM The_Table
WHERE The_Value = 'z'
i wanted to output the following recordset:
Column_1 | Column_2
'First' 'Second'
any help would be greatly appreciated!
-Thanks.
I can't figure out a way to allow more than 4000 bytes to be received at once via a call to a stored procedure. I am storing images in the table that are around 15 - 20 kilobytes each, but upon getting them and displaying them to the page, they are always exactly 3.91 KB in size (or 4000 bytes).
Do stored procedures have a limit on how much data can be sent at once? I double-checked my data, and I am indeed only receiving the first 4000 characters from the varbinary(MAX) field.
Is there a permission setting to allow more than 4k bytes at once?
I have a Cisco 5505 working as a DHCP server, and a server 2008 DNS server running an AD domain.
I am having problems with all XP computers not updating the forward lookup zone. The reverse lookup zone updates are working. Windows vista and 7 computers update just fine. Additionally the DNS server accepts both secure and non-secure updates.
When people are connected through the Cisco's VPN, they cannot resolve to any machines that have reverse lookup zones, but they can resolve entries in the forward lookup zone.
I have tried ipconfig /registerdns, but the forward lookup zone entries for the XP clients are not being populated.
How can I get the XP Dynamic DNS client to make the updates, or what can I do to debug what's going on?
Thanks
I'm trying to write a stored procedure to select employees who have birthdays that are upcoming.
SELECT * FROM Employees WHERE Birthday > @Today AND Birthday < @Today + @NumDays
This will not work because the birth year is part of Birthday, so if my birthday was '09-18-1983' that will not fall between '09-18-2008' and '09-25-2008'.
Is there a way to ignore the year portion of date fields and just compare month/days?
This will be run every monday morning to alert managers of birthdays upcoming, so it possibly will span new years.
Here is the working solution that I ended up creating, thanks Kogus.
SELECT * FROM Employees
WHERE Cast(DATEDIFF(dd, birthdt, getDate()) / 365.25 as int)
- Cast(DATEDIFF(dd, birthdt, futureDate) / 365.25 as int)
<> 0
When i query

I am trying to get recursive data.
Following code returns all parents on the top and then the children.
I would like to get data Parent 1 – his children then parent 2 - his children then parent3 – his children.
How do I do this?
