I have to implement a functionality which is able to read files from FTP and file reside at subfolders and some of subfolder is also dynamic means it may be any thing.
I'm trying to read an xcel file from within the script task of SSIS. I've seen posts that kind of steer me in the right direction, but none to do exactly what I'm looking for. I am loading data from flat files into a database where the source file has text longer than the target column. In order to get the text to "fit" i would like to apply a series of standard abbreviations, for example replace "DOCTOR" with "DR". I started off by simply writing a series of if-then logic; if length (<source>) > <targetlengh>, then replace <long> with <short>. After writing this for 40+ abbreviations I soon realized that this is not the best way to do this. So I came up with the idea of storing all the abbreviations in a .xls file which would be opened and applied via a script task. The problem is that I'm new to VB.net (actually any flavor of VB) and have not been able to read the abbreviations file as of yet.
This is what I've tried thus far, which results with this error: Exception from HRESULT: 0xC001400B
Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)

I've a dataflow task on For Each Loop container at control flow of SSIS package. This For Each Loop container reads the CSV files from the specified location one by one, and populates a variable with current file name. Note, the tables where I would like to push the data from each CSV file are also having the same names as CSV file names.On the dataflow task, I've Flat File component as a source, this component uses the above variable to read the data of a particular file.
Now, here my question comes, how can I move the data to destination, SQL table, using the same variable name?I've tried to setup the OLE DB destination component dynamically but it executes well only for first time. It does not change the mappings as per the columns of the second CSV file. There're around 50 CSV files, each has different set off columns in it. These files needs to be migrated to SQL tables using the optimum way.
Which is the best way to setup the Dataflow task for this requirement?Also, I cannot use Bulk insert task here as we would like to keep a log of corrupted rows.
OBJECTIVE: I would like to read a text file from SQL Server 2000, read the text file content, and load its conntents in a RichTextBoxTHINGS I'VE DONE AND HAVE WORKING:1) I've successfully load a text file (ex: textFile.txt) in sql server database table column (with datatype Image) 2) I've also able to load the file using a Handler as below: using System;using System.Web;using System.Data.SqlClient;public class HandlerImage : IHttpHandler {string connectionString;public void ProcessRequest (HttpContext context) {connectionString = System.Configuration.ConfigurationManager.ConnectionStrings["NWS_ScheduleSQL2000"].ConnectionString;int ImageID = Convert.ToInt32(context.Request.QueryString["id"]);SqlConnection myConnection = new SqlConnection(connectionString);string Command = "SELECT [Image], Image_Type FROM Images WHERE Image_Id=@Image_Id";SqlCommand cmd = new SqlCommand(Command, myConnection);cmd.Parameters.Add("@Image_Id", System.Data.SqlDbType.Int).Value = ImageID;SqlDataReader dr;myConnection.Open(); cmd.Prepare(); dr = cmd.ExecuteReader();if (dr.Read()){ //WRITE IMAGE TO THE BROWSERcontext.Response.ContentType = dr["Image_Type"].ToString();context.Response.BinaryWrite((byte[])dr["Image"]);}myConnection.Close();}public bool IsReusable {get {return false;}}}'>'> <a href='<%# "HandlerDocument.ashx?id=" + Eval("Doc_ID") %>'>File </a>- Click on this link, I'll be able to download or view the file WHAT I WANT TO DO, BUT HAVE PROBLEM:- I would like to be able to read CONTENT of this file and load it in a string as belowStreamReader SR = new StreamReader()SR = File.Open("File.txt");String contentText = SR.Readline();txtBox.text = contentText;BUT THIS ONLY WORK FOR files in the server.I would like to be able to read FILE CONTENTS from SQL Server.PLEASE HELP. I really appreciate it.
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
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'm having trouble with my configurations. All of my configurations are targeting variables and the various properties are all set to expressions containing the targeted variables. I would like (during debugging) to dump out all of the variables.
Is there a way to access all variables from a script task? It looks like you have to enumerate the variables you want in the ReadOnlyVariables or ReadWriteVariables properties. I'd rather not miss one by forgetting to list it.
In the Control flow tab, I have an Execute SQL Task that outputs full Result set into a variable of an object type. Now how can I write the contents of the Full Result Set into a text file using Script Task. I also want to format the following way while I output into a file:
Column Name 1 : Column Value
Column Name 2: Column Value and so on
I tried writing the contents of the Object Variable into a file, but the file had an output of single word: System.__ComObject.
Code for Writing the Full Result Set into a Text File
Dim RSsqloutput as String = Dts.Variables("objVariable").Value.ToString
Dim strVal as String = "File completed on " & Now() & vbCrLf & "------------------------------------------------------" & vbCrLf
I have been struggling trying to read and/or write package level variables from within my custom task. I'd like to be able to get and set values from within the Execute method of my custom task. I have searched this forum and the books online and can't seem to find the answer. I thought maybe I could use an expression on my task (mapping the package variable to a custom task public property) but that doesn't seem to be working for me. I also would have thought I could use the VariableDispenser object from within my task but the collection is empty. I have 3 package level variables configured and can't seem to find a way to access them (with intentions of getting/setting). Could someone point me to a good doc or provide an example that may accomplish this? Thanks!
(I'm using package level variables as a means of passing simple information between tasks that are not using a DB, if there is a better way I'm open to suggestions.)
HI, I need to trigger some packages upon existance of specific files in a particular directory. Sound lkike the file watcher task (from SQLIS) would do the job but I am wondering what is the difference of using this tool instead of a for each loop container. I mean, If a file exists in a directory, the for each loop container will detect it. Since the file watcher is not a service, the package containing it needs to ne scheduled on a regular basis for the filewatcher to detect the file, right? So, a for each loop container would do the job? So, waht wouldbe the advantage of using the file watcher task?
A common issue that I run across with clients is they want only want to process a file if it's finished transmitting to the server. This SQL Server 2005 task reads the properties of a file and writes the values to a series of variables. For example, you can use this task to determine if the file is in use (still be uploaded or written to) and then conditionally run the Data Flow task to load the file if it's not being used. You can also use it to determine when the file was created in order to determine if it must be archived.
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...
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:

Need help reading a binary file see below for details...

Hi, I received a SQL Server 6.5 database (.dat and .Log files). I'm currently running 7.0. Is there any way to read/import this data? I tried to do this: I have installed SQL Server 6.5. And After install, I have created a database with the same names (.dat an .log) and make it bigger than the first .dat and .log files. Then, I have stoped the SQL server service, have deleted the .DAT and .LOG files that i have created, and have copied the first .DAT and .LOG in their place. I have Started the SQL server service and the database was beeing suspected. I stil unable to read data. Can you help me?
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]
I am programming to read read sqlserver log file without shutdowning sqlserver. However it is said that the file is used by another process which I believe is sqlserver. Is there any way to open log file without shutdowning server? I know that Log Explorer can read online log file. But I do not know the technology they are using.
