I have the TypeGuessRows set to 0. I'll have to go back to the code to see if I'm using the IMEX = 1.
Thanks,

I have been asked to redesign the database my company uses for it's web applications. The old database is SQL Server 2000 and I am updating it to 2005.
The old db has many problems, not the least of which is that it simply "evolved". As each new developer worked on it they added tables to do whatever they needed to do instead of finding tables that already contained the data they were operating on. I currently have in excess of 250 tables, a quick search of the pages in the website reveals that at least 60 of these tables are not used. What I need to do is find what data is used and what data is repeated in different tables under different names.
I would appreciate any advice, where to find articles, etc., on how to go about this redesign while minimizing the time I have to spend. Please, point me to where I can find strategies, techniques, etc., to optimize my efforts.
Thanks
Jim

Firstly you need to work out how important your existing data it. How much needs to be retained, etc.
Then you can decide whether you are going to be massaging the existing schema (yuck) and keeping all the data, or you have free reign to redesign the entire thing from scratch.
Try making an entity relationship diagram off the existing schema (or business process - as the existing schema is probably crap) and see what is left out or missing.
Then get signoff on the ERD, and enjoy a nice new schema that makes sense. Try and follow some of our tips in our quick reference sheet under Active Record Friendly Databases - it will give you a much wider choice in selecting your data layer tool.

Thanks for the advice Mark. After several days of working on the old database I went to my manager and told him it was going to be too much work to simply rework the old data into a new database so now I get to build from scratch.
What url for Active Record Friendly Databases? I can't find the page.

Its in the Diamond Binding Quick Reference Sheet, in the downloads section.[^]
While following those tips isn't mandatory, it will certainly make your object model a lot more intuitive - especially if you use a tool like Diamond Binding to handle your data layer (give it a try!).

I would like to know how to link a database table into a local view when the primary source is on another server. I am currently using MS-SQL 2005. Can this be done?
Thanks,

Hi,
im new to using SSRS reports. I created a report and tried viewing it in Firefox, however it is not displaying correctly. The width of the whole report is shrunk on the left of the page. Arents SSRS reports compatible with Firefox browsers?.. or is there something im missing here?
I'd appreciate some help in this...
Thanks
ZiggY.

The SSRS documentation states that reports can only be expected to render correctly in Internet Explorer. A known workaround is to place a hidden textbox on your report that spans the entire page width.

Hi guys,
I've a problem opening a CRecordset object on an Oracle database
using the Microsoft ODBC for Oracle.
The query I'm using is something like the following:
SELECT MAX(OBJECTID) FROM MY_TABLE
the CRecordset object is a dynaset.
When I execute the code I get an error from the ODBC driver
tha says that is not possible to use keyset cursor in join
operations with distinct, union, intersect or minus conditions
or on read only dataset.
Can someone tell me how to solve the problem ?
Thanks a lot !

hi,
In my application i need to import the excel sheet data into a database table "Emp_Profile_Tbl" which is created in the database.
Dim connstr As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("Team wise EMP Profile (2).xls") + ";Extended Properties=Excel 8.0;"
Dim objconn As New OleDbConnection(connstr)
Dim ds As New DataSet
Dim objadapter As New OleDbDataAdapter("SELECT * FROM [Sheet1$]", objconn)
objadapter.TableMappings.Add("Table", "Emp_Profile_Tbl")
Try
'in excel: insert->name->seleziono il range:nomi
objconn.Open()
objadapter.Fill(ds)
dg_empprofile.DataSource = ds.Tables(0).DefaultView
dg_empprofile.DataBind()
Finally
objconn.Close()
End Try
i'm getting the values into datgrid but the values are not saving in "Emp_Profile_Tbl" database table.
pls help me to sort this out.
Thank u,

You haven't written any code to save the data back to your database, so it's hardly surprising that nothing is happening. You need to specify insert/update/delete commands for your data adapter so that changes to the dataset can be propagated back to the database. Read this article[^] for more information.

well I'm sorry I didnt read ur complete code properly but I think u need to use ISNULL (If its SQL SERVER) to convert the nulls to zero or aply a check to see if the value is '' then change it to '0'

I use "INSERT INTO [Flash Turn Parameters] " +
"VALUES ('" + toolPosition1.ToS .....
to create a new record in a database table
and use cmd.ExecuteNonQuery(); to execute the SQL from C# ADO
the 1st field is an auto increment IDENTITY field. How can I find out the value after the record has been created ?
Thanks

use a stored proc like this:
create proc Insert @value int
declare @id int
insert into [bad table name] values (@value)
set @id = scope_identity()
return @id
You could also make it an out parameter
create proc Insert @value int, @id int out
insert into [bad table name] values (@value)
set @id = scope_identity()

You need to write a stored procedure that performs the INSERT operation and then returns the latest IDENTITY value as an OUTPUT parameter. The latest IDENTITY value can be determined by using the SCOPE_IDENTITY[^] command.

Hello,
i have to develop an application to compare a dataset (with around 1000s of records)with a database table which has almost more than 4 million records.
and if the dataset has matches in the table i will mark them as processed. is there any way to achive this .
note: i already have tried comparing them with 2 loops iterating manually in each record...i want some other way
aneef

Assuming you are using SQL Server, a possible solution would be:
1. Serialize the contents of your dataset as XML and submit the data to your database using a stored procedure and the OPENXML command.
2. In your stored procedure, load the serialized data into a table variable whose structure matches the dataset. Add an extra bit field called Processed that can be used to mark matched records.
3. Run an UPDATE query on your table variable, joining it to your master database table. Set the value of your Processed field in the matching records to 1.
4. From your stored procedure, return all records in the table variable where Processed = 1.
Hope this helps.

Hi,
I want to know what are the naming conventions for creating the above mentioned? I went through some of the adventure works tables and looking at the indexes they either start with IX or AK, for example:
IX_EmployeeDepartmentHistory_DepartmentID
Please advise.

Hi,
I have 3 tables, namely:
CategoryGroup
CategoriesInCategoryGroup
Categorty
CategoriesInCategoryGroup has only 2 fields, which I made the primary key each, namely CategoryGroupId and CategortyId, and they each reference the corresponding table. So basically they are foreign keys.
I have a question when creating an index in the CategoriesInCategoryGroup table. Do I create 1 index, or should I create a separate index for CategoryGroupId and CategortyId in the CategoriesInCategoryGroup table?
Please advise.
Brendan
