Hi,
I just noticed that if I have an identity column in a table, when I insert new rows MS SQL 2008 is automatically filling up the sequence if there are discontinuity. I mean, if in my identity column I have 1,2,5,6 if I insert other two rows in the table the system puts automatically 3,7 in the identity column.
Do you know how to control this behavior?
THANKS
I am using Castle ActiveRecord as my ORM. When I try to store unicode strings, I get question marks instead.
Saving unicode strings worked perfectly when I was using mysql, but when I recently switch to SQL Server it broke. How should I go about fixing this?
Hi,
I have recently discovered the tablediff utility of SQL Server 2005.
I have 2 instances of the same database each on a different server.
Is it possible to compare all tables using tablediff without having to replicate the same command while only changing the table name?
For example, compare table1 on server1 with table1 on server2 then compare table2 on server1 with table2 on server2, until all tables have been compared.
I'm doing a little digging and looking for a explanation on how SQL server evaluates MIN(Varchar).
I found this remark in BOL: MIN finds the lowest value in the collating sequence defined in the underlying database
So if I have a table that has one row with the following values:
Data
AA
AB
AC
Doing a SELECT MIN(DATA) would return back AA. I just want to understand the why behind this and understand the BOL a little better.
Thanks!
I have an application which intensively uses DB (SQL Server).
As it must have high performance I would like to know the fastest way to insert record into DB.Fastest from the standpoint of execution time.
What should I use ?
As I know the fastest way is to create stored procedure and to call it from code (ADO.NET).
Please let me know is there any better way or may be there are is some other practices to increase performance.
Is it possible to write a plugin or a form for SQL Server Enterprise Manager version 8? I'm doing some simple queries all the time to admin the databases. So wondering if I could write something for it.
For Data Explorer I would like to add support for a Batch separator.
So for example if users type in:
select 'GO' go select 1 as go
Go
select 100
I would like to return the three result sets.
Its clear that I need some sort of parser here, my hope is that this is a solved problem and I can just plug it in. (writing a full T-SQL parser is not something I would like to do)
What component / demo code could achieve splitting this batch into its 3 parts?
I have an sql statement that returns this result below,and I want that the num will drag the latest(by date) num that is not null. I can't get it right.
I want to add somthing like this:
case
when num is null then max(num where date<my_date)
my result now:
Date num
1.1 0
2.1 1
3.1 NULL
4.1 NULL
5.1 4
what I want:
Date num
1.1 0
2.1 1
3.1 1
4.1 1
5.1 4
Situation:
Running a report on SQL Server Reporting Services
When I do a Preview of the Report all my charts look fine. No problems.
When I run a subscription for the report, the chart look different. Like completely different legends are gone etc.
Any ideas what the cause would be?
BTW the charts are Dundas Charts.
The following SQL query isn't working. I think the error is on the first line.
SELECT SUBSTRING(tbl_news.comment, 1, 250) as tbl_news.comment,
tbl_news.id, tbl_news.date, tbl_news.subject, tbl_users.username FROM tbl_news
INNER JOIN tbl_users ON tbl_news.creator = tbl_users.id
ORDER BY date DESC

Hi,
I'm trying to do some work with my SQL table.
I have 2 buildings with room numbers 1 - 100 in building 1 and 101 - 199 in building 2.
I have a location field (which I've just created) and want to run a query to populate it with either 'Building 1' or 'Building 2' depending on which room number it has in the 'Room' field.
Many thanks for your help.
Regards
Scott
I have a SQL Server 2008 database with 300 tables. The application I have to design is an Windows Forms app, .NET 3.5, C#.
Which is the best way to work with LINQ2SQL ?
I intend to make a datacontext for each business entity.
Is there any problem ?
I need to know if this way of working with LINQ has any disadvantage or can create performance issues ?
Thanks.
I have the following table...
TABLE: Accounts
ID (int, PK, Identity)
AccountType (int, PK)
Username (varchar)
Password (varchar)
I have created a composite key out of ID and AccountType columns so that people can have the same username/password but different AccountTypes.
Does this mean that for each foreign table that I try and link to I'll have to create two columns?
I’m using SQL Server 2008
I have a table called Categories which contains category_Id and parent_category_Id, so each category can has a child and the child can has a child and so on (it is dynamic).
So if i have category A and category A has child B and child B has child C and child C has child D. I want to get all the child tree of A using SQL so when I give this query the id of A its result will be the ids of A's child which is B,C & D.....any ideas.
Thanks in regards,
I am trying to compare a series of strings like the following
rodeo rodas
carrot crate
GLX GLX 1.1
GLX glxs
the comparision need not be case sensitive
i am trying to write a sql where i am updating the first string with the second string if they match approximately. Here except the second string all the other examples match. I would like to write a query which updates the strings except the second one.
is this possible directly in a query in ACCESS
thanks
is it possible to retrieve by using connection.getschema() the description item from a sql server table column, just like it's possible to retrieve the column name, data type, is nullable, column default value, etc?
I have the following Transact SQL query using a union.
I need some pointers as to how this would look in LINQ i.e some examples
wouldbe nice or if anyone can recommend a good tutorial on UNIONS in linq.
select top 10 Barcode, sum(ItemDiscountUnion.AmountTaken) from
(SELECT d.Barcode,SUM(AmountTaken) AmountTaken
FROM [Aggregation].[dbo].[DiscountPromotion] d
GROUP BY d.Barcode
UNION ALL
SELECT i.Barcode,SUM(AmountTaken) AmountTaken
FROM [Aggregation].[dbo].ItemSaleTransaction i
group by i.Barcode) ItemDiscountUnion
group by Barcode
So i need to figure out how i can get a record count value and use that count as a new value to insert into a table.
Ex: In My Stored Procedure
@Count int
What im looking for
@Count to equal "select top (1) _fieldName from _someTable order by _fieldName Desc"
Finally
insert into _newTable (_fieldName) values (@Count)
End
I dont have to use a variable, just trying to demonstrate what im really trying to do. My SQL knowledge is pretty limited so no laughing, or smirking! ;)
Hi,
I want to get tree representation answer from my t-sql stored procedure. How can I do it ?
Does .NET have a predefined types for working with xml-answers from stored procedures ?
I'm getting my first exposure to data warehousing, and I’m wondering is it necessary to have foreign key constraints between facts and dimensions. Are there any major downsides for not having them? I’m currently working with a relational star schema. In traditional applications I’m used to having them, but I started to wonder if they were needed in this case. I’m currently working in a SQL Server 2005 environment.

Hello everyone,
I am using SQL Server 2008 Enterprise. I met with issue which says line 9 of store procedure foo is meeting with dead lock issue. My question is how to find exactly the 9th line of the store procedure?
My confusion is because of coding format issue, how to locate 9th line correctly.
thanks in advance,
George
