i've found HEX in the books online but seems that it isn't available in SQL2005...

but i've found this (ofcourse microsoft undocumented) one :

DECLARE @x BINARY(16) ( or int if you please)

SET @x = 255

SELECT master.dbo.fn_varbintohexstr(@x)

SQL Server is not designed to present data. It is designed to store and retrieve data efficiently.

If you need to show integers in hexadecimal in your application, make the client-side application do it. The same goes for things like string concatenation.

That's true,

but the (my concept) SQl server needs to prepare some things so the (dum and transparant) applications just need to pickup data end send it to hardware...
if the hardware gets a firmware update we don't need to replace all the applications, we only need to modify one stored proc.. so easy to maintain..
the apps are installed on embeddeds also so we don't want them to do a lot of time absorbing work.

ofcours we can also use services on the server who can do the work but that takes a lot of extra work and my experience is that MSSQL is very powerfull en can handle those things without any problems..

but i guess this is my opinion..ofcourse any suggestions or better concepts to do this are very welcome..

Thx..

So why are stored procedures, views and functions implemented in MSSQL then ?

i solve things this way :

insert into A
select fielda, fieldb, LEFT(fieldc, 50) from B Where fieldd = 1

i suppose retrieve all the 50.000 records to a service truncate the string in the client app and sending 50.000 update records from a client app to your MSSQL server is taking more time then this query...

tell me if i'm wrong. Smile | :)

Write SQL that will remove PK and set it to another column

Hello,

I have a table with a primary key on Serial No. I need to add a new column called softwareID and set that to the new primary Key.

It is possible to write some sql what will remove the PK from Serial No, and set the softwareID as the new PK?

I was thinking about dropping the table and creating a new one, but I don't want to lose the data.

Many thanks,

Steve

Change schema, without destroying the data

Hello,

I have a sql 2005 server database and using .Net 2005.

The client has a database when contains all there business data. In the currently I have been making changes to the schema i.e. creating new table, altering procedures, etc. All these has been done by writing the scrips and when the program installs it will execute these scripts. The customer gets an update every few months.

However, the updates are becoming more and more frequent and also becoming more complex and sometimes difficult to keep track of all the table's schema.

Is it possible to send them a backup so that they can restore it with all the changes I have made to the schema without destroying all their data?

Is there any software that can be used to automate this process?

What could make this difficult as we are in different offices. Development office and the customer's office in different countries.

Many thanks for any advice,

Try using Red-Gate SQL compare. You can use it to compare both schema and data and it can be automated using .Net scripts. The best thing to do would be to keep a backup of the schema for each series of updates. When you make a new release, create a backup. Then the next time you need to release a new set of changes, restore the last backup to a place where you can run SQL compare to generate the change scripts. Then you can send those scripts with your update to the customer.

hi,

Everyone know this error? the database has been placed in state by user "Admin"!

We are using a shared database in access databases. When more than one user has connect to my databases by my application (my program developed by vb.net) at the same time, the following error message appears. "The
database has been placed in a state by user 'Admin' on machine XXXXX that
prevents it from being opened or locked."

* Although i already add the "Persist Security Info=False;Mode=Share Deny None" in my OleDbConnection, it still got same error!

How to solve this error? please help!

My following code as below:

Try
DB = New OleDbConnection("Provider=microsoft.jet.oledb.4.0; data source=C:\prdsystem\prdnsf.mdb; Persist Security Info=False;Mode=Share Deny None")
DB.Open()
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Information, "")
End
End Try
Da = New OleDb.OleDbDataAdapter(sql, DB)
Ds = New DataSet
Da.Fill(Ds, "emp")

Creating a SqlDbType.SmallDateTime parameter

I'm trying to create a SqlDbType.SmallDateTime parameter and have been unable to find the correct answer.

I'm trying to take a date in mm/dd/yyyy format from a text box and pass it to a stored procedure.

This is about as close I have got but it still doesnt work:

SelectCommand.Parameters.Add("@dateofbirth", SqlDbType.SmallDateTime).Value = DateTime.Parse(StoredProcedureValues[3]).ToShortDateString();

Does anyone know what the answer is ?

Thanks

When you are adding a datetime value of any sort to a database leave it in a date, I mean DATE, format if possible. Otherwise you must format it correctly to insert. So ensure that the value you are parsing to DateTime is a date value and dont set it to short date string.

SmallDateTime is about precision not how it looks in the DB[^]

Ahhh, you need to ensure that all types are the same.

So if you have some int datatypes along with varchar or char you need to cast the int to a varchar. CAST(IntColumn as varchar(length))

sql server 2000 millisecond issue

Hello,

I was trying to build an application using sql server 2000 and asp.net which would use real time resources, and; I have been facing an issue in which when two transactions occur at the same time, down to hh:mm:ss; then in that case a deadlock occurs and none of the transactions are completed. They remain pending unless u manually goto enterprise manager and change the seconds by making them +/-1

This issue can be reduced considerably if milliseconds can be used hh:mm:ss:fff. Is there a way to implement this?

Deadlocking does not occur because you have a datetime. It occurs because you have two resources which are locking each other.

a loop that increments a value in the selection clause?

Red_Wizard_Shot_The_Food15-Mar-07 2:30

15-Mar-07 2:30

I’m trying to make a loop that will select a count of all entries that have a "TimeIn" value on the date defined by an input parameter with an hour value between x & y.

So the first pass through the loop would select a count of all rows with a TimeIn between 00:00:00 and 01:00:00 on the selected day ...

The second pass will select a count of all rows with a TimeIn between 01:00:00 and 02:00:00.

finally it will return counts for each hour in the day.

This is my first attempt at loops in SQL so any push in the right direction would be much appreciated.

Thanks.
