I need to retrieve columns names(instead of select * from) as single row from table in dynamic way.
i m using following query.
its working fine while using from selected database. but its not working when i m running from different database.
DECLARE @columnnames varchar(max)
select @columnnames = COALESCE(@columnnames,'')+column_name+',' from INFORMATION_SCHEMA.COLUMNS(nolock)
where table_name='table_20141224'
select @columnnames
I need to pass database name dynamically like using by variable.
Is this possible to use variable after from clause. or any other methods?
eg:
DECLARE @columnnames varchar(max)
DECLARE @variable='db_month11_2014'
select @columnnames = COALESCE(@columnnames,'')+column_name+',' from @VARIABLE.INFORMATION_SCHEMA.COLUMNS(nolock)
where table_name='table_20141224'
select @columnnames

I have a need to create a line graph report in SSRS 2008. The report should show the top 10 servers from a group of servers with the highest CPU utilization for the last day. The report is for Microsoft System Center Operations Manager 2012. I have a SQL query that will return the average CPU for all of the servers in the group, with the average for each hour (24 records per server).
How can I get the top 10 servers with the highest average CPU? I think I need to create an average of the averages, then select the top 10. Here is the SQL query I have so far:
Use OperationsManagerDW
GO
SELECT
vPerf.DateTime,
vPerf.SampleCount,
cast(vPerf.AverageValue as numeric(10,2)) as AverageCPU,
vPerformanceRuleInstance.InstanceName,
[code]....

I would like to create a database that keeps track of our companies subject matter experts. I have roughed out some of the tables. I would appreciate any feedback on if this is the right approach and if there might be any issues when I start writting a front-end (probably VB 2005).
What makes this interesting (at least for me) is that a subject has an owner and at least 1 "expert", possibly up to 3. Here is what I am thinking for tables:
tblEmployee
EmployeeID (PK)
LastName
FirstName
etc......
tblSubject
SubjectID (PK)
Description
tblOwner
SubjectID (FK)
EmployeeID (FK)
tblExpert1
SubjectID (FK)
EmployeeID (FK)
tblExpert2
SubjectID (FK)
EmployeeID (FK)
tblExpert3
SubjectID (FK)
EmployeeID (FK)
Does this make sense? Would I run into any issues when trying to display this on a form in VB?
Thanks in advance for any help!!!!!

The following query was used for retrieving dates for the last 7 days . Untill February this query was running fine and would return the last seven days date including today.
SELECT DISTINCT TOP 7 Convert(DateTime, DATEDIFF(DAY, 0, DateCreated)) AS DateCreated,
datepart(dw,DateCreated) AS WeekNum from [TechnologyRepository].[helpdsk].[WorkDetails]
WHERE DATEDIFF(DAY, Convert(DateTime, DATEDIFF(DAY, 0, DateCreated)),GETDATE()) <= 7
However from March (not sure of the exact date)..the query below would only give us 7 days until yesterday..i.e it would list dates from 3/19,3/20,3/21,3/22,3/23,3/24,3/25 and not 3/26 ..
I changed the query to <= 6 and it works as expected. But still not sure why it would not return todays date with <= 7.
SELECT DISTINCT TOP 7 Convert(DateTime, DATEDIFF(DAY, 0, DateCreated)) AS DateCreated,
datepart(dw,DateCreated) AS WeekNum from [TechnologyRepository].[helpdsk].[WorkDetails]
WHERE DATEDIFF(DAY, Convert(DateTime, DATEDIFF(DAY, 0, DateCreated)),GETDATE()) <= 6

Grade Table is:
Grade_letter lowbound_marks uperbound_marks
A 85 100
B 60 84
C 0 59
Suppose some another query returns marks.Now, I am stuck with the query which takes the grade_letter based on the marks falling in the range given above. I want a query which is not hardcoded and calculates the grade based on the values given in the table only.

I am trying to figure out an automated way to get a list of all the tables used in a set of 275 T-SQL scripts. i do not want to go through each script manually, look at all the from clauses and write down the tables used.
I have managed to get all the 275 scripts into a table on SQL Server 2008 R2 database. one column per each script, so there are 275 rows in the table.
FYI: each query can have multiple result sets, so multiple from clauses can exist.
For Example:
Query 1 = SELECT * FROM Table1 a
INNER JOIN Table2 b ON b.Field = a.Field
LEFT OUTER JOIN Table3 c ON c.Filed = b.Field
UNION ALL
SELECT * FROM Table4 a
INNER JOIN Table5 b ON b.Field = a.Field
LEFT OUTER JOIN Table6 c ON c.Filed = b.Field
Desired Output = Table1, Table2, Table3, Table4, Table5, Table6

I am struggling trying to clean some data and identify duplicate records. I used fuzzy grouping in SSIS and provided back a series of groups. The issue is some of the individual records can appear in multiple groups (so in reality the groups should be combined). This is best explained with an example:
Original Data
key1 key2
647942600014
647942285437
2324662490640
2324662285437
2324662066128
2222 2285437
2222 1111111
9999 1111111
9999 2222222
Should look like:
22222600014
22222285437
22222490640
22222066128
22221111111
22222222222
I only choose 2222 as the surviving key because it was the smallest number. I really do not care which number remains as long as it is the same across.
I tried playing with self joins between the tables but have had no success.
I am using Sql Server 2008 and the number of records could 500K to 1MM.

--BookingRef ABCDE

6666
Bob 5555
7777
--BookingRef FGHIJ
Jenny 8888/
9999/

I know I can get a simple function to return the all data, but I do not know how to only include the pax name once.

I am trying to find a way to add into a table a flattened (comma seperated list) of email addresses based on the multiple columns of nformation in another table (joined by customer_full_name and postcode.
This is to highlight duplicate email addresses for people under the same customer_full_name and Postcode.
I have done this using a loop which loops through concatenating the email addresses but it takes 1minute to do 1000. The table is 19,000 so this isn't really acceptable. I have tried temp tables, table variables and none of this seems to make any difference. I think that it is becuase i am joining on text columns?
Create table #tempa
(
customer_Full_Name varchar(100),
Customer_Email varchar(100),
Postcode varchar(100),
AlternateEmail varchar(max)NULL
)
insert into #tempa (customer_full_name,customer_email,postcode)

SO when i try to load from  Master table to parent and child table i am using using expresssion likeÂ
select B.ID,A.* FROM FLATFILE_INVENTORY AS A JOIN DMS_INVENTORY AS B ONÂ
A.ACDealerID=B.DMSDEALERID AND A.StockNumber=B.STOCKNUMBER ANDÂ
A.InventoryDate=B.INVENTORYDATE AND A.VehicleVIN=B.VEHICLEVIN
WHERE convert(date,A.[FtpDate]) = convert(date,GETDATE()) Â and convert(date,B.Ftpdate) = convert(date,getdate()) ;
If i use this Expression i am getting the current system date data's only  from Master table to parent and child tables.
My Problem is If i do this in my local sserver using the above Expression if i loaded today date and if need to load yesterday date i can change my system date to yesterday date and i can run this Expression.so that yeserday date data alone will get loaded from Master to parent and  child tables.
If i run this expression to remote server  i cannot change the system date in server.
while using this Expression for current date its loads perfectly but when i try to load yesterday data it takes current date date only not the yesterday date data.
What is the Expression on which ever  date i am trying load in  the master table  same date need to loaded in Parent and child table without changing the system Date.

I'd like some ideas on how to help out my VB staff when it comes to the tick ( ' ) mark being used in front end applications. When users enter data into the front end, and they include tick marks (eg: Sam's Auto Store), this causes trouble in how the app uses that data in a WHERE clause and other places. Does anyone have any slick ideas or experience in handling this. We have experimented with search & replace, double tick marks ( '' ), etc...

I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon
