Hi;
I am using SQLXML 4.0 for loading bulk load data. I'm having a problem with connectionstring, when I use sqlclient i.e. sqlconnection it gives me error and does not connect to the database. When I use the connection string providing SQLOLEDB provider it works.
private static SqlConnection getConnection()
{
SqlConnectionStringBuilder conStrBuilder = new SqlConnectionStringBuilder();
conStrBuilder.DataSource = "abc";
conStrBuilder.InitialCatalog = "abc";
conStrBuilder.UserID = "abc";
conStrBuilder.Password = "abc";
return new SqlConnection(conStrBuilder.ConnectionString);
}
private void ExecuteBulkLoad()
{
SqlConnection conn = getConnection();
conn.Open();
SQLXMLBulkLoad4 objXBL = new SQLXMLBulkLoad4();
try
{
objXBL.ConnectionString = conn.ConnectionString; // it does not work
objXBL.BulkLoad = true;
objXBL.ErrorLogFile = @"C:\SQLXML3Books.errlog";
objXBL.KeepIdentity = false;
objXBL.Execute(@"C:\booksmapping.xml", @"C:\Books.xml");
}
catch
{
throw;
}
finally
{
// close of the writer and the stream objects.
objXBL = null;
}
}
But if I use objXBL.ConnectionString = "provider=SQLOLEDB.1;data source=abc;database=abc;uid=abc;pwd=abc";
It worked fine.
Any help?
Thanks

Hi;
I've just started playing with SQLXML 4.0, here is the code which I am using to load the XML into database.
SQLXMLBulkLoad4Class bulkLoad = new SQLXMLBulkLoad4Class();
bulkLoad.ConnectionString = connString;
bulkLoad.BulkLoad = true;
bulkLoad.KeepIdentity = false;
bulkLoad.XMLFragment = true;
bulkLoad.Execute("C:\books.xsd", "C:\books.xml");
My question is that, the mapping file i.e. xsd or booksmapping.xml is compulsory to pass or we can have that information into xml data file? We want to avoid two files to maintain.
Thanks

Hello everyone,
I have been working with VBA code in MS Access 2003. I have a Command button which sends an email and then update the column of a table. Here is what I have...
<br />
DoCmd.SendObject, , acForMatTXT, strWho, , , strSubject, strText, -1<br />
strSQL = "UPDATE [Action Item Table] SET ysnActionAssigned = -1 " & _<br />
"Where [Action Item Number] = " Me.Action_Item_Number & ";"<br />
On Error GoTo Err_Execute<br />
CurrentDB.Execute strSQL<br />
on Error GoTo 0<br />
<br />
Err_Execute:<br />
' Here I display error message in a message box<br />
I am getting an error of "Type mismatch". Can someone tell me what is going wrong.
Thank you.

Which line is triggering the Type Mismatch?
|
|
|
|
|
CurrentDB.Execute strSQL
When executing the SQL command.

Are you explicitly using Dim to create the variable strSQL as a string?
|
|
|
|
|
Yes.
It is like a local variable in the same function.

Try adding a Debug.Print line to output your constructed sql UPDATE statement to the immediate window. You can check to make sure the form values are being incorporated the way you think they are. You can also then copy and paste the actual statement from the immediate window and execute it through the SQL view of an access query. This is a good way to test whether or not there is a problem with the UPDATE statement itself.

Mike,
Thank you for you valuable suggestion. Debug.print is a good way to troubleshoot software bug. I am still getting the "Type mismatch" error but it is updating the table. So I comment out the error check part for now.

Hi Bashar. Wow - that's interesting. So the UPDATE command is successfully executing? AND you are getting a Type Mismatch error on the same line?
Just to see what happens, try changing the line
CurrentDB.Execute strSQL to
dim iResult as integer
iResult = CurrentDB.Execute(strSQL)
|
|
|
|
|
I would guess it is this
codeamin wrote: [Action Item Number] = " Me.Action_Item_Number & "
that is causing your problem. in particular the = " Me.Action_Item_Number & "
You are missing the first &. As far as the query is concerned you are trying to enter the literal string value 'Me.Action_Item_Number &' into a numeric column.

Jon,
Good thinking. Here is what I have my code now:
<br />
Dim num as Integer<br />
num = Me.Item_Number<br />
strSQL = "UPDATE [Action Item Table] SET [Action Item Table].ysnActionAssigned = -1 " & _<br />
"WHERE [Item Number] = " & num & ";"<br />
CurrentDB.Execute strSQL<br />
I was still getting a "Type Mismatch" error if I check for error. I comment out the error check as it was updating the [Action Item Table].
Thank's for your help.

Hi,
I've a running .NET 2.0 app that connects to DB locally (thru ODBC),
using an entry in connectionStrings section in web.config.
Now I want to connect to a second DB, but adding just
another entry in web.config (see below).
(replaced angle brackets by [])
[connectionStrings]
[add name="My1stDbConn" connectionString="Dsn=FirstDB" providerName="System.Data.Odbc" /]
[add name="My2ndDbConn" connectionString="Dsn=SecondDB" providerName="System.Data.Odbc"/]
[/connectionStrings]
How do I tell my code I wanna use the second entry, instead of first one?
Thanks in advance.

Hi Eugenio. Consider what your connection code looks like for the first connection - you must be identifying it by its name "My1stDbConn" at some point. You would do the same thing to create your second connection - just refer to its name "My2ndDbConn" when pulling connection string values from web.config.

Hi Everybody,
I wrote code deleting data in Excel file by using OLEDB.
But ADO.NET show error
"Delete data in a linked table is not supported by this ISAM"
Now, I want to delete data in Excel file.
Please help me!!!!
Thanks you
Tran Thai Nam

To my knowledge, there is no way to delete rows in an Excel spreadsheet through OLEDB. You may need to use interop calls directly to the Excel COM objects to accomplish this.
|
|
|
|
|
I think so. Then I change Delete Command to Update Command (fill null value) in ASP.NET.
UPDATE [SHEET1$] SET F2='1' WHERE F1='1'
But I recieved the error "Operation must use an updateable query". I don't know how to fix this bug.
Please help me!
Thanks

I choose my table key is int type and use identity. I don't know HOw many record it have to corrupt my database? Please help me. If that not good please tell me a better way. Thanks
|

I don't know what you mean by "when will my database corrupt"? Do you mean how many rows can you insert before the key has to wrap around? If you are using an int type you have a maximum of 4294967296 unique values.

Hi,
I want my query to exclude all fields that are null and zero length.
This is what I use now:
AND ItemDiscount <> ''
Is there a better way to go?
thanks,
Ron

That just excludes the empty string, you also need to exclude the nulls.
AND ItemDiscount <> '' AND ItemDiscount IS NOT NULL
Does this help?

A small team of software engineers have re-architected the Microsoft .NET Pet Shop application by using Software Tree’s NJDX object-relational mapping (OR-Mapping) technology. Here is the abstract of the project report:
The .NET Pet Shop application is designed to show the .NET best practices for building enterprise n-tier applications. In this ASP.NET based web application, classes are defined to represent domain model objects like products, users, addresses, and orders. These domain model objects are persisted in relational databases (e.g., SQL Server, Oracle) using a data access layer (DAL). The current DAL implementation, which uses raw SQL and low-level database APIs, is pretty hard to understand and maintain This report describes how such a data access layer can be replaced with a much simpler and shorter (35% less lines of code) implementation using NJDX OR-Mapping technology from Software Tree. In addition to greatly simplifying the architecture, the NJDX approach provides greater flexibility and delivers superb performance.
Project Report
Press Release
The full implementation code ships with the NJDX software that is available for a free 30-day evaluation from Software Tree’s web site at http://www.softwaretree.com.
Thank you.

I need to upgrade our db server and was wondering if anyone had any experience with opteron based processors.
I want to use HP ProLiant DL385 with 2 AMD Opteron 280 processors (Raid 5 and 8GB Ram)
I want to use 64bit version of windows and sql server 2005. (System price around $15,000)
How would this compare to comparable Xeon processor based configuration?
