How Can I Read One External File (*.txt,*.csv) Through
Dec 14, 2001
How can I read one external file (*.txt,*.csv) through
stored procedure in MS Sql Server 2000 ?
On the database Interbase its very simple :
[CREATE TABLE table [EXTERNAL [FILE] ’ <filespec>’]
( <col_def> [, <col_def> | <tconstraint> …]);
EXTERNAL [FILE]“<filespec>
” Declares that data for the table under creation resides
in a table or file outside the database;
<filespec> is the complete file specification of the
external file or table]
Please advice
Thanks

This is how I used to create DTS in SQL SERVER 2000 and then create a job for scheduling.
' Visual Basic ActiveX Script
'************************************************************************
Function Main()
url="http://www.pageName.com/abc.aspx"
set xmlhttp = CreateObject("MSXML2.XMLHTTP")
xmlhttp.open "post", url, false
xmlhttp.send ""
'msgbox xmlhttp.responseText
Main = DTSTaskExecResult_Success
End Function
Now how will I do the same in the SQl SERVER 2005.
Please help as it is very critical to my work.
Thanks in advance.Manpreet

Hi,
I have to write a query that queries a database table and a text file wich is delimited using fixed width values. I have seen some examples using access or another databse but not much about a text file. Is this the best way? Idon't want to set up a linked server. I want everything to be within the query.
My understanding is that I should be able to do it since a text file can be a valed OLE DB datasource, but I am having trouble finding example syntax. Can all my connection info be passed with the OPENROWSET function? Can I do it by just writing a query? Or do I have to set up and configure other things?
Any guidence, tips, advice, examples, or links of syntax appreciated.
Mike

Hello,
I'm having an issue with a CLR Stored procedure. Everything works great in a 32 bit environment, I have a CLR SP that updates an xml file stored on a local drive. When I execute the Stored proc it does go and update what I want it to in a 32 bit system. When I run the CLR SP on a 64 bit cluster, I seem to have give the "everyone" group write permissions to my G: drive (which is where the file is located that I'm updating). What security context is this SP running under? I thought it would be either under the SQL Service account (which is a domain user in the local administrators group) or what I'm logged in as when I run it from Management Studio (which is a domain admin, also in the local administrators group). If I have given the local administrators group "Full Control" access to the G: drive, why isn't this enough? Why do I have to give the Everyone group write access?
The security context seems odd to me, it seems like it's not running as either one of those 2 users I mentioned, because if it was, then it should be able to update the xml file.
Any help appreciated. Here's the error I'm getting:
Msg 6522, Level 16, State 1, Procedure usp_XMLWriter, Line 0

Hello Experts,
I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle).
PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not..
What should go here ?
->Under Class A
public override DTSExecResult Execute(Connections connections, VariableDispenser variableDispenser, IDTSComponentEvents componentEvents, IDTSLogging log, object transaction)
{
//Some code to read file and write it into new file
return DTSExecResult.Success;
}
public const string Property_Task = "CustomErrorControl";
public const string Property_SourceConnection = "SourceConnection";
public void LoadFromXML(XmlElement node, IDTSInfoEvents infoEvents)
{
if (node.Name != Property_Task)
{
throw new Exception(String.Format("Invalid task element '{0}' in LoadFromXML.", node.Name));
}
else
{
try
{
_sourceConnectionId = node.Attributes.GetNamedItem(Property_SourceConnection).Value;
}
catch (Exception ex)
{
infoEvents.FireError(0, "LoadFromXML", ex.Message, "", 0);
}
}
}
public void SaveToXML(XmlDocument doc, IDTSInfoEvents infoEvents)
{
try
{
// // Create Task Element
XmlElement taskElement = doc.CreateElement("", Property_Task, "");
doc.AppendChild(taskElement);
// // Save source FileConnection
XmlAttribute sourcefileAttribute = doc.CreateAttribute(Property_SourceConnection);
sourcefileAttribute.Value = _sourceConnectionId;
taskElement.Attributes.Append(sourcefileAttribute);
}
catch (Exception ex)
{
infoEvents.FireError(0, "SaveXML", ex.Message, "", 0);
}
}
In UI Class there is OK Click event.
private void btnOK_Click(object sender, EventArgs e)
{
try
{
_taskHost.Properties[CustomErrorControl.Property_SourceConnection].SetValue(_taskHost, propertyGrid1.Text);
btnOK.DialogResult = DialogResult.OK;
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
#endregion

I have a filetable that contains a binary file. I need to do a selective read of the file stored in the file table. I can write a C# CLR function that will open the file, read n bytes the from a starting byte. Or I can write a SQL statement that reads the stream in the filetable into a VARBINARY variable using SUBSTRING beginning at the starting byte (offset from 1) for the same n bytes.
Both give me the same result. However, the SQL statement takes considerably longer to read. I know there is overhead in reading through SQL (interpreted language), but the difference in performance is substantial, and I can only attribute this performance degradation if SQL first tries to "load" the entire stream before it identifies the portion of the stream that it needs to read beginning at the starting byte offset.
I wonder if this is the case or if there is another option to read a stream from a filetable directly through SQL queries that is more efficient.

I got a problem when developing SSIS packages.
For security reason, the sensitive information must be encrypted, and they should be configurable dynamically (by an ASP.NET application).
so I tried several ways to achieve this,
1. use SSIS Package Configurations to generate an XML config file
It's a convenient way to generate config file. but the passwords are not encrypted (or I don't know how).
2. use Variables and Property Expressions
I can set variables by reading from an external custom xml config file which was content encrypted (read and decrypt the custom config file in a script task). but in a FTP Connection Manager entity, the Password property can not be set via Property Expressions.
Is any way to store password encrypted to an external file?

Anyone reading XML disk-files into SQL Server?
I have a process that I may want to do this with.
It would be a stored procedure that would read the XML attributes into 2 tables, the number of attributes could be 1-N, so I thought XML would be a good choice. Also, one of the attributes could be up to 4000 characters. I think this may limit our options, can 100-150 4000 character strings be passed in a standard call to a query/proc in SQL?
Currently the client application makes round-trip network calls to save upwards of 100 pairs of data. 1 header row, and many detail rows. All within a transaction.
I think If we move an XML file to the SQL box, then do all the import/save work on the "Server" side it would be much better. Cutting the transaction time down a lot by not doing so many round-trips at network speed...
Thoughts?

Hi All
I am trying to load DBF files into SQL server within CLR (actually if just running the select statement outside, say within the SQLQuery window, i got the same result), but with the following error:
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "VFPOLEDB" for linked server "MYDBF" does not contain the table "T8866064". The table either does not exist or the current user does not have permissions on that table.
I created the linked server in this way
EXEC sp_addlinkedserver
@server = 'MYDBF',
@provider = 'VFPOLEDB',
@srvproduct = 'My Data',
@datasrc = 'c:data'
i did not create the login since my SQL instance is running under a superaccount with all privilege.
What frustrates me is that i can read most of the dbf files, but just a few of them is not readable.
Can anyone give me some hints on it?
by the way, i am using vfp9.0
thanks
michael
