Oh my apologies you need to have coulumn of that name I think.
Why dont you add one more coulmn name as sizeofrow with varchar(20) datatype.
this will work i believe if not please refer here:

A client sent me a backup copy of his database so that I could debug a stored procedure.
After I restored the .bak file into my copy of SQL Server 2005, I see that it renamed every table by prepending the original name of the database to each table name.
So now every table must be referred to by "schema.tablename" instead of just "tablename". This breaks every stored procedure in the database because they all still refer to the tables by their old names.
Why does it insist on renaming the tables, and how do I get it to stop doing that whenever I restore a database from a .bak file?

I've never seen it do that before ... I've always restored databases back to databases with the same name and it works fine.

I am in the proccess of writing a small membership program and all the info is being stored in an MS Access database. I've gotten stumped on coding the datagridview's "DataRelation" object because I'm having to code through three table levels.
To explain, I want to create families (Father, Mother, Children) and link them through the DataGridview.
I have a master table called "tblFamilyNames" that holds the "primary key" and anniversary date. I then have a table called tblFamilyDetails. It links the family(Father, Mother, Children) together by storing the primary key value from tblFamilyNames in a column called "intFamilyID".
In tblFamilyDetails, there is a column: "intMemberID" that points to a record in the third table: tblMembers".
My question is, how do I bind the first table: "tblFamilyDetails" with the third table: "tblMembers" so that the user can see the member's info without seeing the intermediate table: "tblFamilyDetails"?
may your code be error free

This may not be the answer that you're expecting, but have you considered using Views to de-normalize the data? It sounds like you could create a "Family" view that is an INNER JOIN of tblFamilyNames and tblFamilyDetails. This could then be JOINed to tblMembers to give you a single unified view of the data.

What does your INSERT query look like?
|
|
|
|

My INSERT query is in the following function
<br />
Public Function SaveTransInfo(ByVal idrequestman As Long, ByVal iddestinationInfo As Long, ByVal Y As String, ByVal M As String, ByVal D As String, ByVal Goods As String, ByVal idworker As Byte, ByVal Tonaj As Double, ByVal place As String, ByVal sdate As String) As Boolean<br />
Dim sqlStr As String<br />
Dim myCon As OdbcConnection = GetConnection()<br />
sqlStr = "INSERT INTO TransInfo(idrequestman,iddestinationInfo,Y,M,D,Goods,idworker,Tonaj,place,sdate) VALUES(" + idrequestman.ToString & "," & iddestinationInfo & ",'" & Y & "','" & M & "','" & D & "','" & Goods & "'," & idworker.ToString & "," & Tonaj.ToString & ",'" & place & "','" & sdate & "');"<br />
Try<br />
Dim myCommand As New OdbcCommand(sqlStr, myCon)<br />
myCon.Open()<br />
myCommand.ExecuteNonQuery()<br />
Catch ex As Exception<br />
myCon.Close()<br />
HttpContext.Current.Response.Write(ex.Message)<br />
Return False<br />
End Try<br />
myCon.Close()<br />
Return True<br />
End Function<br />
<br />
thanks for your attention<br />

You may need to adjust the permissions on the database file so that it can be written to by the ASP.Net user.
In Explorer navigate to the file and go to it's properties. Select security and add the built in ASPNET user and give it read/write permissions.

Hmmm... I'm not sure what the cause is really. If you hard code the entire SQL statement (just for testing problems, does the error still occur?
I've also found this, which might be useful:

Do you have a typo? It looks like either the ProposalSystem database doesn't exist or it has some problems with it. Did you delete some system tables from this database?

I'm using SQL Server 2005 and when trying to create an Agent Job I get the following error:
Unable to cast object of type 'Microsoft.SqlServer.Management.Smo.SimpleObjectKey' to type 'Microsoft.SqlServer.Management.Smo.Agent.JobObjectKey'. (Microsoft.SqlServer.Smo)<br />
I've googled it but the only solution provided was to repair the SQL Native Client, which didn't solve my problem.
Any ideas what else should I try?
Cheers,

Can any one suggest me the answer plz.
Thanks in advance

You can create a temporary table by prefixing the name with # which which create a table for that user in the TempDb database on the SQL server, meaning that each user will have their own copy
You can also do global temporary tables as well if you need to.
