I am using two tables, courses and video with a one to many relationship with the videos table being the many. How do I populate the courseID in the video table with the corresponding courseID from the courses table using a combination of Formview & Gridview or two Gridviews, or a dropdown field populated with the course name and courseID in a Form or details view.This is a simple task in Access accomplished using a dropdown list to select the correct video.

We did some "at scale" fuzzy lookup tests today and were rather disappointed with the performance. I'm wanting to know your experience so I can set my performance expectations appropriately.
We were doing a fuzzy lookup against a lookup table with 25 million rows. Each row has 11 columns used in the fuzzy lookup, each between 10-100 chars. We set CopyReferenceTable=0 and MatchIndexOptions=GenerateAndPersistNewIndex and WarmCaches=true. It took about 60 minutes to build that index table, during which, dtexec got up to 4.5GB memory usage. (Is there a way to tell what % of the index table got cached in memory? Memory kept rising as each "Finished building X% of fuzzy index" progress event scrolled by all the way up to 100% progress when it peaked at 4.5GB.) The MaxMemoryUsage setting we left blank so it would use as much as possible on this 64-bit box with 16GB of memory (but only about 4GB was available for SSIS).
After it got done building the index table, it started flowing data through the pipeline. We saw the first buffer of ~9,000 rows get passed from the source to the fuzzy lookup transform. Six hours later it had not finished doing the fuzzy lookup on that first buffer!!! Running profiler showed us it was firing off lots of singelton SQL queries doing lookups as expected. So it was making progress, just very, very slowly.
We had set MinSimilarity=0.45 and Exhaustive=False. Those seemed to be reasonable settings for smaller datasets.
Does that performance seem inline with expectations? Any thoughts to improve performance?

Hi all,
I have a table that looks something like this: -
county fname sport
------ ----- -----
surrey tara squash
surrey tara hockey
surrey tara tennis
kent tom tennis
kent tom football
kent tom rugby
I want to read through the sport table and create a distinct list of sports which can be used to create a new table that would look like: -
County fname squash hockey tennis football rugby
------ ----- ------ ------ ------ -------- -----
surrey tara YES YES YES
kent tom YES YES YES
I am using the following code: -
DECLARE @sql NVARCHAR(MAX)
SELECT @sql = 'create table ey_report_temp (county nvarchar(100),fname nvarchar(100), ' +
STUFF((SELECT DISTINCT ',[' + sport + '] nvarchar(100) '
FROM ey_report FOR XML PATH('')), 1, 1, '') + ')'
SELECT @sql
exec sp_executesql @sql
SELECT * from ey_report_temp
--------------------------------------------
DECLARE @county nvarchar(max)
DECLARE @fname nvarchar(max)
DECLARE @sport nvarchar(max)
DECLARE merge_cursor CURSOR FAST_FORWARD
FOR SELECT county, fname, sport from ey_report
OPEN merge_cursor
FETCH NEXT FROM merge_cursor INTO @county, @fname, @sport
WHILE @@FETCH_STATUS = 0
BEGIN
select @sql = N'
update ey_report_temp
set ' + @sport + ' = ''YES''
where county = ''' + @county + '''
and fname = ''' + @fname + ''''
print @sql
exec sp_executesql @sql
if @@ROWCOUNT = 0
begin
select @sql = N'
insert into ey_report_temp (
county, fname, ' + @sport + '
) values ( ' + @county + ', ' + @fname + ', ' + @sport + ')'
exec sp_executesql @sql
end
FETCH NEXT FROM merge_cursor INTO @county, @fname, @sport
END
CLOSE merge_cursor
DEALLOCATE merge_cursor
select * from ey_report_temp
drop table ey_report_temp
This creates the new table fine however, when it trys to poulate I get the following EM, can anybody help? thanks in anticipation

Hello,
Just when I thought I was starting to understand SSRS just a little and then I encounter a strange (maybe not too strange) of an issue.
I have a DataSet which runs a stored procedure and it requires 10 parameters. When I run it in the dataset portion itself it runs fine however, it will not work when I choose to Preview it. I refreshed my dataset and even rebooted my machine. Can anybody shed some light on this?
Thanks

I have a table that I would like to update with the current dateTime of Today. The Table Field is called "DateTimeStamp" with a format of SmallDateTime -- I'm using VS 2008.
When I use the following command and then cmd.ExecuteNonQuery -- the table is correclty filled in with the exception of the DateTimeStamp field. Instead of 3/23/2008, I get the value 1/1/1900 ...
SqlCommand cmd3 = new SqlCommand("UPDATE CameraPods SET CameraBlock1_ID = 98, CameraBlock2_ID = 99, Status = 1, DateTimeStamp = 3/3/2008");
any ideas?

Hi,
I have a flat file with columns from a geographical hierarchy such as:
Country Zone State County City Store Sub Store , etc.
The file also has data columns for months to the right of the above columns such as:
Jul Aug Sept ......... basically 25 of these columns for two years' data for one product and another set of 25 columns for another kind of product. A typical record in the file looks like:
Country Zone State County City Store Substore
USA Southeast FL Hillsborough Tampa walmart Fletcher
May04_ProdA ....Jun06_prodA May04_ProdB...Jun06ProdB
144 160 180 158
I need to upload this data into a staging table in SQL Server 2005 using SSIS, I created a table with the geographical hierarchy columns but am trying to figure out a way to load the monthly data. I can create 50 columns for the 50 months ( 25 months for each product) but that would be very crude.
Is there a better way of inserting data from this flat file into a destination table? I need all the data in the staging table in one upload.
Thanks.

I am having a torrid time trying to populate a FACT table in ORACLE.
I have so far tried two approaches -
1. Identified the change type for records - meaning I mark the record as inserts or updates based on the availability of the key in the FACT table. I used a conditional split and then used two OLE DB destination tasks to load the FACT table. But this failed as I was pretty much inserting on both the conditions (inserts and updates). So this attempt would count as a batch update process attempt.
2. Tried to also write a stored procedure in ORACLE destination database and then use that stored procedure to execute record by record using OLE DB Transformation task. But this did not fly as well due to the fact that SSIS could not understand the oracle SP and could not parse the information out.
Thank you

In my SSIS package I used the Web Service task to populate a SSIS variable with data from an XML feed. Then in the Data Flow I used a XML Source to import that data into a table on my SQL Server. When I looked at the data i noticed that the some of the fields contained CRLF pair. These CRLF pairs are being only populated by xml nodes that contain no data and are self-terminated. Below is a sample of the XML feed that is causing the problems. the DR_M_Initial and DR_Type1 nodes are populating CRLF's to the table.
Can anybody give me some insight on this problem. I am performing a workaround using the SQL REPLACE function in an Update statement to strip out ch(10) and ch(13), but this just seems a little cluegy to me.
Sample XML
---------------------------------------------------------
<?xml
version="1.0" encoding="utf-16" ?>
- <ROOT xmlns="">
<ROWRESULT>
<DR_NUMBER>1</DR_NUMBER>
<DR_L_NAME>SMITH</DR_L_NAME>
<DR_F_NAME>JOE</DR_F_NAME>
<DR_M_INITIAL />
<DR_TYPE1 />
</ROWRESULT>
</ROOT>
Thanks,

Sorry I'm pretty new to SQL so I don't know if this is a simple question. I have a table, and I am trying to add a column to the table and populate this column using what would be called an 'IF' function in Excel.
Basically 'column A' has numbers in it. I want SQL to look at 'column A' and if the first 5 digits of the number in 'column A' are 00001, then put 'description A' into new column 'column B'. If the first 5 digits of the number in 'column A' are 00002, then put 'description B' into 'column A' etc.
Any ideas?

I have a column within a table which is already truncated/deleted all records within (Microsoft SQL 2008). I have to now populate the column with sequential numbers up to 50,000 records arbitrary numbers (doesn't mater) up to 7 characters.
what SQL statement I need to write that will automatically polulate the newly empty table with A000001,A0000002,A0000003, or any form for that matter etc so that I can sort number the records within the table.
I have approximately 50000 records which I need to sequentially entered and I really dont want to number the column manually via hand editing.

I have a table of id numbers that I wish to mask. My thought was to create a new column for this new id number and populate it with a unique sequential value - start at 1 and go as high as needed. My problem is that I cannot recall how to populate that column with a number...

I'm experienced using queries to extract data, but I'm new to actually creating tables, except through Access. I work with many records of data, so populating the data by hand is not an option. I created a test database (ValTest) and a test table within that database (ClaimTest). I created a text file (DataTest.txt) with the same layout as I defined for ClaimTest. I want to populate ClaimTest with the data from DataTest.txt. I was told the only way to do that using SQL Server Express was to use a utility called BCP. So I found a page on the Microsoft website talking about BCP. It gave some examples, so I opended up the Command Line window, pointed to the directory that contains the database and text file and typed "BCP ValTest.ClaimTest in DataTest.txt -T -c". I get 3 errors: Named Pipes Provider: Could not open a connection to SQL Server [2], Login timeout expired, and An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
I tried looking around and finding where I could change the settings, in case that was indeed the problem, but was unable to find anything. Does anyone have any suggestions?
Thanks

I have a combo box where users select the customer name and can eithergo to the customer's info or open a list of the customer's orders.The RowSource for the combo box was a simple pass-through query:SELECT DISTINCT [Customer ID], [Company Name], [contact name],City,Region FROM Customers ORDER BY Customers.[Company Name];This was working fine until a couple of weeks ago. Now wheneversomeone has the form open, this statement locks the entire Customerstable.I thought a pass-through query was read-only, so how does this do atable lock?I changed the code to an unbound rowsource that asks for input of thefirst few characters first, then uses this SQL statement as therowsource:SELECT [Customer ID], [Company Name], [contact name],City, Region Fromdbo_Customers WHERE [Company Name] like '" & txtInput & "*' ORDER BY[Company Name];This helps, but if someone types only one letter, it could still bepulling a few thousand records and cause a table lock.What is the best way to populate a large combo box? I have too muchdata for the ADODB recordset to use the .AddItem methodI was trying to figure out how to use an ADODB connection, so that Ican make it read-only to eliminate the locking, but I'm striking outon my own.Any ideas would be appreciated.Roy(Using Access 2003 MDB with SQL Server 2000 back end)

I am stuck on finding a solution to transpose source data from a system via a metadata look-up table into a destination table. I need a method to transpose/pivot the source data into columns (which are by various data-types). The datatypes for each column are listed in a metadata table.
Source Data Table:
Table Name: Source
SrcID AGE City Date
01 32 London 01-01-2013
02 35 Lagos 02-01-2013

I'm working with an existing package that uses the fuzzy lookup transform. The package is currently working; however, I need to add some columns to the lookup columns from the reference table that is being used.
It seems that I am hitting a memory threshold of some sort, as when I add 3 or 4 columns, the package works, but when I add 5 columns, the fuzzy lookup transform fails pre-execute:
Pre-Execute
Taking a snapshot of the reference table
Taking a snapshot of the reference table
Building Fuzzy Match Index
component "Fuzzy Lookup Existing Member" (8351) failed the pre-execute phase and returned error code 0x8007007A.
These errors occur regardless of what columns I am attempting to add to the lookup list.
I have tried setting the MaxMemoryUsage custom property of the transform to 0, and to explicit values that should be much more than enough to hold the fuzzy match index (the reference table is only about 3000 rows, and the entire table is stored in less than 2MB of disk space.
Any ideas on what else could be causing this?

Hi
I'm designing a database for my final year project at University, and have run into a bit of a dilemma with one of the tables. Basically, it's an equipment loan database where both students and lecturers need to be able to book and borrow equipment. To avoid having two separate bookings tables (i.e. StudentBookings and LecturerBookings) I've got students and lecturers combined into one table called 'Borrowers'. The trouble comes because the clients want the lecturer storing in the booking information table, which can get quite messy because lecturer information is stored in the same table as borrower information meaning that I basically need to relate both the Booking.BorrowerID and Booking.LecturerID to Borrowers.BorrowerID.
In theory, I think this could be solved by creating a View called Lecturers that pulls the required information for Lecturers out of the Borrowers table and then link Booking.LecturerID to the ID of the view. In practice, I've got a couple of queries:
1) Is it possible to perform a JOIN on a view in the way that I would need to here?
2) To keep things nice and clear, is it possible to 'rename' the BorrowerID to LecturerID whilst creating the View?
Sorry if some of this isn't too clear. Please ask any questions to clarify what I mean if you need to.
Cheers
Jon

Hi,
I'm inserting records into a Table1 with the following fields :
tabID int 4ClientID int 4..etc etc.
In the insertitem template, I want the user to enter a Clientcode into textbox1. Then I want that client code validated against a lookup table, ClientTable and if valid, get the ClientId value from that ClientTable, so that I can populate the ClientID field in Table1.
I've got a mental block and I cannot see how I can do that !
Any ideas most gratefully appreciated.

Employee
EmployeeId
FN
LN
DeptName (fk)
Department
DeptId (pk) unique
DeptName unique
*** Or could i do this to make the employee record more meaningful without needing a join. ***
Employee
EmployeeId
FN
LN
DeptName (fk)
Department
DeptId (pk) unique
DeptName unique
*** Or should i just do this and get rid of the Id Field***
Employee
EmployeeId
FN
LN
DeptName (fk)
Department

i have very very basic knowledge of SQL like the ability to add, delete, update, select records and the ability to drop/create tables but i want to know how to integrate a lookup table into a field (very much like MS Access users can do with ease).
here is my example;
i have two tables - Club and Player
Club:
Club_Id
ClubName
Abbr
Player:
Player_Id
Name
Club_Id
the idea is that a single club can have several players. in the players table, i want the Club_Id field to act as the drop down whereas if a player changes club at any time, i can just refer to that player and change his Club_Id by scrolling down a list of values in SQL Server Management Studio 2005.
how can this be achieved by any chance, help would be very much appreciated.
