Hi, I'm not sure if I'm doing my UPDATE's and DELETE's the proper way:
Basically, I want to make sure what I updates, or deletes, in fact exists (ie not deleted by another user) before I actually perform the operation:
Code:
o_session = SetupBISConnection(...)<br />
trx = o_session.BeginTransaction()<br />
<br />
Try<br />
'IF the object with specified UIN does not exist (that it's deleted by another user), then NHibernate will throw ObjectNotFoundException.<br />
obj = o_session.Load(GetType(CObj), UIN)<br />
Catch ex As NHibernate.ObjectNotFoundException<br />
'object to be updated does not exist - abort delete<br />
Throw ex<br />
End Try<br />
<br />
'Okay, if no exception so far, it means the object is there...<br />
o_session.Delete(plan)<br />
o_session.Flush()<br />
<br />
trx.Commit()
Any pointer? Thanks in advance.

Hey guys, just downloaded, "NHibernate Query Analyzer", I unpacked it, but now wondering what to do with it. Is there any tutorial for this tool? Or should I resort to SQL Server's SQL Profiler... Thanks.

Hi all,
I have got a problem with retrieving data from the tables, because I found out that the keys to join these two tables are mismatching. The key in one table HAS SPACES in it, but the key in the other table does not. Even I have tried to use the REPLACE function to get rid of the spaces to make them matching, it still does not work. Please have a look at the code below, and give me some ideas how to solve it.
SELECT P.UniformItem, P.ProductCode, P.ProductSize, U.Description, U.Rank, U.RepPolicy
FROM tProductCode P INNER JOIN vUniformItemJoin U
ON Replace(P.UniformItem,' ','') = Replace(U.UniformItem,' ','')
Very much appreciate if you can help me out.
Cheers

Wow - you match using string values, and then call functions like this within your select statement ? You need to fix your database, I'd suggest that P and U should both have an index which represents a UniformItem, and then a table should match the index to a string representation. That's called database normalisation. If you're not going to do that ( and you should ), then you should at least massage data going in, so you don't need this sort of stuff making the most simple select statement messy.

ADO/ADOX Gurus out there:
I cannot seem to find any way to read the description of an existing field in an existing Access DB. The frustrating part is that I can certainly write one when creating a new field and appending it to a table, but I can never seem to read the description for an existing field.
The following code will work and display the description on the webpage, but only because it reads it from the object it just appended. If I were to close everything, set it to nothing, then open a new object, it cannot be read. One would think that if you can write it, you can read it...am I wrong here?!?
I have tried any number of combinations of objects, properties, and collections from ADO and ADOX. Has anyone actually been able to do this?
Your help is deeply appreciated,
Brian

As far as I know there is no method to change the output of the GetXml function. So you will have to convert it afterwards. If you are willing to read some docs have a look at the XslTransformclass. I provides a .Net wrapper around XSLT which can be used to transform the structure of XML files.

Hi:
Please check on the following:
1) Since it is a remote machine, ping it and see whether ICMP Packets are being acknowledged. These will ascertain you that the system is up.
2) You need to ensure that you are connecting to a proper instance of SQLServer. Not always Instance Name and System Names can be identical. You could have chosen a different instance for the SQLServer in case there are multiple on the same system.
3) You need to ensure that the SQLServer Service you are connecting is running on the remote system and on the correct port.
4) In line with (3), also ensure that port 443 communication between your system and the remote system are not blocked by either your firewall or the remote system firewall.
Did this help you?

Hi All,
I'm trying to work with stored procedure in VB.NET but there were some problems with that, I hope someone can help me.
First, is there a way to manage a stored procedure's transaction from VB.NET?, I tried something like this (see code below) but when I do commit an error appears because the transaction is already closed.
................
Dim objConexion As New OleDbConnection(strConexion)
Dim trans As OleDbTransaction
Dim objComando As OleDbCommand = New OleDbCommand("fun_codigos", objConexion)
objComando.CommandType = CommandType.StoredProcedure
.......defining parameters...............
objConexion.Open()
trans = objConexion.BeginTransaction
objComando.Transaction = trans
Dim objDataReader As OleDbDataReader = objComando.ExecuteReader
objDataReader.Close()
objConexion.Close()
Dim salida As Int64
salida = objComando.Parameters("@p_cod_servicio").Value
Label1.Text = salida
trans.Commit() -------> here an error appears!
I have to manage the transaction from VB.Net not from inside the stored procedure.
Second, I want to pass some parameters from VB.NET to an stored procedure but there is an error like this: "ORA-06550: line 1, column 18: PLS-00382: expression is of wrong type ORA-06550: line 1, column 7: PL/SQL: Statement ignored "
I checked parameter's type in VB.NET and there were the same as in stored procedure.
I'm working with Oracle 8i.
I hope you can help me.
Thanks in advance

DISCLAIMER: I don't know much about oracle so this is just a guess out of the air.
Does your stored procedure have a begin/commit transaction block in it already? I'm guessing that if your stored procedure commits the transaction already then putting a BeginTransaction() and Commit() in your code may not be necessary.

the stored procedure makes an autocommit transaction when finish, but I don´t want it to do that. It´s like the stored procedure is inside a .NET loop and I want to commit when the loop (in .NET) finish so I don´t want the stored procedure autocommiting every time I call it.

Hi I have written a basic Webservice that returns values from a Dataset here is a code snippit
[WebMethod]
public DataSet CTX (string filter)
{
try
{
iDB2Connection connDB2=new iDB2Connection{
"DataSource=TDC01;" +
"userid=user;password=pass;DefaultCollection=collection;");
DataSet ds = new DataSet();
iDB2DataAdapter adpt = new iDB2DataAdapter();
string szSQLstmt = "Select * from table where REF='" +@filter+"'";
adpt.SelectCommand = new iDB2Command(szSQLstmt,connDB2);
adpt.Fill(ds);
return ds;
}
This works fine when i test it in ie returns the data in xml however what i want to be able to do is use this in Biztalk however biztalk can only see the root node <dataset> and nothing else can anyone offer me any advice of how to solve this problem.
Thanks in advance

Hi,
I have written a stored procedure in SQL Server which uses temp tables and returns the rows of a temptable.

Why is that? If this wouldnt work how do i implement this.
Am using a custom version of crystal report bundled in VS .NET.
Any help would be appreciated.

Just a few things off the top of my head:
Uses specific logins.
Do not grant access to the public role.
Grant access only to the objects that the users/roles actually require.
daneshmand wrote:

Stored procedures can be used to protect the tables from direct access. You can revoke access to the tables and grant access only to stored procedures. That way the only way to access a table is through the stored procedure. This layer of abstraction can protect you as you can set up additional checks in the stored procedure before allowing the operation to complete.
