I think the type is wrong on your parameter, you should be using dbtype.int or SQLdbType.int32

I am using SQL server 2k, can any one please tell me the length param of data type binary. I have checked it from MSDN http://msdn2.microsoft.com/en-us/library/ms188362.aspx[^]
binary [ ( n ) ]
Fixed-length binary data with a length of n bytes, where n is a value from 1 through 8,000. The storage size is n bytes.
Does that mean that SQL server doesn't store data/image larger than 8 kb.

SQL Server 2000 divides the database's storage into 8KB pages. A single row cannot span pages, it must fit within a single page. The exception is that text, ntext and image columns (referred to as LOBs, Large [or Long] OBjects) are (typically) stored off-page, although you can enable on-page storage with the 'text in row' table option for values that are smaller than 8000 bytes.
Because of this limit, it won't allow you to create a column whose size is bigger than this (8000 bytes for varbinary, 8000 characters for varchar, 4000 characters for nvarchar). If you create multiple large variable-length columns but the actual values you insert exceed 8000 bytes in total, you will get an error.
SQL Server 2005 adds new varchar(max) etc types. These can be used in identical ways to the limited variable-length types but are still stored off-row, unlike text and image columns which had some limitations. This is now the preferred way of storing LOB data. The old way will be removed in a future version of SQL Server (although I think still present in the upcoming SQL Server 2008).

You mean like select * from mytable ?

Nope. At some point, you need column names.

There's the really bad practice of select *. You really should use column names though.

Given the other replies - what is it that you are trying to do - maybe we can provide some other advice?

Hi all,
I've been trying to find a similar question but couldn't find one so forgive me if this has already been dealt with.
Is there a way that I can immediately obtain the value of an auto incrementing identity field in SQL if I insert a new record?
Let's say I run the following command:
SqlCommand myCommand = new SqlCommand("INSERT INTO Users (UserName, Age) VALUES ('Joe Bloggs', 30)", myConnection);
but the Users table has an auto incrementing identity field called UserID. Is there a way I can obtain the new value of UserID without having to run a subsequent SELECT UserID FROM Users WHERE... query?
Thanks

After the INSERT do: SELECT SCOPE_IDENTITY();
This is all in one command. So you then do a ExecuteScalar() to get the value back to your application.
|
|
|
|
|
You could also use a SELECT @@identity;. But I think that it's better to use the Scope_Identity()-function, because @@identity returns the last identity value set in the current connection, while Scope_Identity() returns the last identity value that was set in the current scope (e.g. in a stored procedure).

Yes, so if there there are triggers involved then SCOPE_IDENTITY() will ensure the correct identity is returned.

I don't think so. You can define aliases for the columns though, e.g. SELECT Option_1 AS [1], Select Option_2 AS [2] etc...

Hi,
i insert new row in sql server with this syntax
Dim insert_transaction As SqlCommand
insert_transaction = New SqlCommand("insert into Transaction (Transaction_Id,Account_Id,Type,Amount,Date,Time) values ('30','" & account & "','Account Transfer','" & money.Text & "','" & Today & "','" & time & "')", myConnection)
insert_transaction.ExecuteNonQuery()
the error appear in ExecuteNonQuery()
the question is
how i insert new row in vb.net connect with sql server ?

|
|
the error "Icorrect synyax near the keyword 'Transaction'" and i have table transaction in database
and anther question : how can insert primary key ( Transaction_Id) automatic without i insert it manual
|
|
|
|
|
declear the field Transaction_Id as identity and write the query with @@IDENTITY AS ID
like this
insert_transaction = New SqlCommand("insert into [Transaction] (Transaction_Id,Account_Id,Type,Amount,Date,Time) values ('30','" & account & "','Account Transfer','" & money.Text & "','" & Today & "','" & time & "') @@IDENTITY AS ID ", myConnection)
object autonumber = insert_transaction.ExecuteScalarIdentity()
|
|
|
|
|
1. new error appear :"there is no source code available for the current loaction
if i click yes the same last error appear"
2. and I'm not understand the how declare the @@IDENTITY , and if declare it there is no meaning for insert value for transaction_Id
