Is there a way to get the profiler without installing Microsoft Sql Server?
If the answer is no, which edition do I need to get the profiler? Do I need the Developer Edition?
Hi,
I'm using SqlServer 2005 and i'm trying to achieve something like:
In the same select statement i want to get the first x rows and the last x rows.
SELECT TOP(5) BOTTOM(5)
Of course 'bottom' does not exist so i need other solution.
I believe there is an easy and elegant solution that i'm not getting.
Doing the select again with Group By Desc is not an option.
Thanks.
What are those pro/subtle techniques that SQL provides and not many know about which also cut code and improve performance?
eg: I have just learned how to use CASE statements inside aggregate functions and it totally changed my approach on things.
Are there others?
I have an Oracle SQL query as part of a stored proc:
DELETE FROM item i WHERE NOT EXISTS (SELECT 1 FROM item_queue q WHERE q.n=i.n) AND NOT EXISTS (SELECT 1 FROM tool_queue t WHERE t.n=i.n);
A bit about the tables:
item contains about 10k rows with an index on the n column
item_queue contains about 1mil rows also with index on n column
tool_queue contains about 5mil rows indexed as well
I am wondering if the query/subqueries can be optimized somehow to make them run faster, I thought that deletes were generally fairly fast
I am storing images in a SQL database , right now I have images being stored in separate tables depending on the object the images belong to, is there any reason ( performance etc..) why I should keep it this way and not store all images in the same table?
I have a table; let it be called table1; with the following fields and data
I need a query that returns the record with the maximum value in Field3 for each group of records having the same value in Field2. So that the query returns:
How could this be done using SQL queries ?
I am trying to insert NULL value in SqlServer if I have null value in corresponding C# String object like below :
String Residence = xmlDoc.Descendants("Appointment").Single().Element("StateOfResidence") == null ? null : xmlDoc.Descendants("Appointment").Elements("StateOfResidence").Single().Value;
I am using Entity framework for Database access. So if Residence is null, 'NULL' gets inserted into Database instead of NULL. How can insert NULL for null ?
I want to use infinite WHILE loop in SQL 2005 and use BREAK keyword to exit from it on certain condition.
while true does not work, so I have to use while 1=1.
Is there a better way to organize infinite loop ?
I know that I can use goto, but while 1=1 begin .. end looks better structurally.
For example, imagine that I want to see if a user exists in my database:
Select * from Users where inputID = Users.ID
Then if that result brought 0 items, then the user exists, correct?
How can I do something like this using a pure Linq-to-SQL class?
I would like to do something like this i.e., use wild card characters in the in clause:
SELECT * FROM mytable WHERE keywords IN ('%test%', '%testing%')
This is not supported in MS SQL.... Is there some other way to achieve it...
Looking for something other than:
SELECT * FROM mytable WHERE keywords like '%test%' or keywords like '%testing%' or.....
I use SQLServer 2000.
Suppose I have two tables like the following:
Area
----------------------------------
ID| Name | HierarchyLevel
----------------------------------
1 | World | 1
2 | America| 2
3 | Europe | 2
4 | Africa | 2
5 | USA | 3
and
AreaHierarchy
------------------------
ID | ParentID | ChildID
------------------------
1 | 1 | 2
2 | 1 | 3
3 | 1 | 4
4 | 2 | 5
where
AreaHierarchy.ParentID and AreaHierarchy.ChildID are FKs of Area.ID
How can I find the nth parent of USA?
Is it possible without looping?
Probably not.

I have a SQLServer 2012 Sequence object:
/****** Create Sequence Object ******/
CREATE SEQUENCE TestSeq
START WITH 1
INCREMENT BY 1;
I have a SP that runs some queries inside a transaction:
BEGIN TRAN
SELECT NEXT VALUE FOR dbo.TestSeq
<here all the query update code......>
ROLLBACK TRAN
If the transaction fails all the updates are rolledback without problem but the Sequence is not rolled back I guess because Its out of the scope of the transaction.
Any clue on way to handle that?
Thanks

Hello Guys!
I've two MS SQL tables: Category, Question. Each Question is assigned to exactly one Category. One Category may have many subcategories.
Category
Id : bigint (PK)
Name : nvarchar(255)
AcceptQuestions : bit
IdParent : bigint (FK)
Question
Id : bigint (PK)
Title : nvarchar(255)
...
IdCategory : bigint (FK)
How do I recursively count all Questions for a given Category (including questions in subcategories). I've tried it already based on several tutorials but still can't figure it out :(
Is it possible to create a table which has a check constraint on one of the column whose value lies within the result set given by another sql query

or any thing like that.
I dont have to use it anywhere but still want to know.
