Deleting Lines From A Text File

May 29, 2007

I have a flat file that look like this



############################################################
# Market Issue Lookup
# Applies to: Muni,Pfd,Govt,Corp
###########################################################
LU_MARKET_ISSUE| |AUSTRALIAN|Corp|
LU_MARKET_ISSUE| |BULLDOG|Corp|
LU_MARKET_ISSUE| |CANADIAN|Corp|
LU_MARKET_ISSUE| |WARRANTS|Muni|
LU_MARKET_ISSUE| |YANKEE|Corp|



############################################################
# Maturity Type Lookup





and i want it to look like this



LU_MARKET_ISSUE| |AUSTRALIAN|Corp|
LU_MARKET_ISSUE| |BULLDOG|Corp|
LU_MARKET_ISSUE| |CANADIAN|Corp|
LU_MARKET_ISSUE| |WARRANTS|Muni|
LU_MARKET_ISSUE| |YANKEE|Corp|



Basically remove any line that start with a "#" or any blank lines..



I am assuming you can do this only using a script component and not directly through ssis..but i am not too familiar with scripting...so some code would be helpful



Thanks for any help in advance.

BCP Import With Blank Lines In Text File

Jan 4, 2007

I am trying to bcp import a text file into a SQL Server 2000 database.The text file is coming out of a java application where orderinformation is written to the text file. Each record is on it's ownrow, so the last item in each record has a new line character at theend of it to create the next row. This works well in creating the filehowever bcp does not like to import this text file with the extra blankline at the end. If I change the new line character to the beginning ofthe records then there is a blank line at the top of the text file,which bcp also does not like. Does anyone have any suggestions for meto get around this issue?Thanks,

SQL Search :: Delete Multiple Lines Using Loop

Aug 31, 2015

How can I run through an array of ID's and delete the fields associated to it in a single table?  I have a lot of bad data that needs to be removed.  BTW, I'm using the SQL Server Management Studio to do this.

I'm currently doing by hand by using the following.

USE database;
DECLARE @id integer
SET @id = XXXXX
DELETE FROM table WHERE id = @id;

I would like to use the same code but with a slight variation to support an array.

Integration Services :: Delete Text File Created Through Flat Line Connection?

Jul 6, 2015

created a very basic flow in SSIS: extracted table data through ole db connection, added multicast and as end result i created a flat file destination (with .txt file) and a ole db destination.

My question is; how can i delete the .txt file before executing the flow again? Want to avoid that the .txt file has duplicated rows after a second execution of the flow. Is it possible to use scd component or is this way to complicated? A for each loop?

i need a similar solution for the data that will be transported through the ole db destination task....

Filtering Lines In A DTS Text Import

Jan 19, 2004

I have a DTS that reads in a bunch of transactions daily to a tran history table. I read them in from a text file each day. The problem is, that about half of the lines in the text file contain semicolons because they are comments. What I do now is, import the whole thing, and then do a Delete on my tran hist table for all lines with semicolons. As my tranhist table grows, this Delete will start to take a long time. How do I filter it so it doesn't even import the lines with semicolons to start with, that will run faster and save me time later.

Thanks,
Andrew

Extremely Long Lines Of Text

Sep 25, 2006

I have a dtsx package that works fine with one exception. When I open the dtsx package in BI, it gives me the following message:

Document contains one or more extremely long lines of text. These lines will cause the editor to respond slowly when you open the file. Do you still want to open the file?

When I respond yes, the package opens and I can edit or execute with no problem. Still, I want to understand what could cause this message to occur and, more importantly, how I can get rid of the message. When I try to simply execute the package I still get the same error and it seems this will be a problem for trying to run the package from SQL Server agent.

It seems likely to me that this message refers to the dtsx file (in xml format) itself. Does that make any sense?

Bold Lines In Text Based E-mail

Jun 13, 2008

Hi everybody,
I'm sending text based e-mails using SMS and I need some lines to be bolded. I don't want to switch to HTML based just to make some lines bold. But, I cannot figure out how I can make the lines bold in SMS. I didn't see any options in SMS to bold a line of text. Is there any any function available for varchar datatype that will bold the text or something like that? or will I have to go to HTML based e-mail? any help is greatly appriciated.

Error - Document Contains One Or More Extremely Long Lines Of Text

May 6, 2008

Hi,

I've created a dataset with 27 measures and 20 query parameters. When attempting to load the report containing this dataset I'm shown the message;

'Document contains one or more extremely long lines of text. These lines will cause the editor to respond slowly when you open the file. Do you still want to open the file.'

If I do open the file it does indeed respond very slowly or even hangs.

I can manually format the XML code but amending the code in any way (i.e. using the layout designer to move a chart) removes my formatting and re-introduces the problem.

Are these an unreasonable amount of measures / parameters?

Environment;
VS2005 v8.0.507
MSSQL 2005 9.00.1399.06 Build 3790 SP2
Windows Server 2003 SP2

Many thanks.

Removing Lines From A Flat File

Oct 5, 2006

Hi There,

I am parsing a directory of flat files and looping through it with a foreach loop. Some of the files have lines that contain characters that I would like to remove. In fact, it would be good if I could remove the entire line. Is there a way to do this with a Script Task or some other way.

Thanks for your help.

Reading First Few Lines From Flat File

Jun 5, 2007



Hi,

I have a very simple question, how do i read the first couple of lines only from a flat file source. Let me illustrate with an example:



**Source file***

Date of refresh 04/05/06 **

abc, 123

bac, 156



I need a way to read the first line 'Date of refresh 04/05/06 **' and get the date '04/05/06' ; and store the date in a variable.



Right now, I have a flat file source and a script component, which receives a connection from the flat file source, The script component is reading the lines, but thrice instead of once. It would be great if I can program the script component to terminate after reading the first line only. Any help would be appreciated very much.



Thanks

Bidyut

SSIS: Multi-Record File Using Merge - Getting Blank Lines

Mar 27, 2008

I have used the following useful article regarding exporting a multi-record file:
http://vsteamsystemcentral.com/cs21/blogs/steve_fibich/archive/2007/09/25/multi-record-formated-flat-file-with-ssis.aspx

I have created the 9 datasources, ordering each on a field commmon to all.

I have created the required derived columns headers and have merged all the record types into a file.

The resulting file looks fine, except for the odd blank line between record types. Any ideas regarding cause and what to do to fix?

Any help is most appreciated!

Excel File Manipulation - Repeat First 7 Columns Based On Number Of Lines In Transaction

Jul 10, 2015

I have a task where I need to process roughly 60000 excel spreadsheets and bring them into a SQL Server 2014 database. All excel files have the same format and same number of identical columns. I have set up an SSIS package that is using Foreach Loop Container to look into a folder and process these files one at a time and load them to a table. The mappings are straight-forward, no problems there.

I am attaching a sample spreadsheet with two tabs - current structure and desired structure.

Basically what I need to do is to repeat the first 7 columns based on the number of lines in a transaction.

The number of lines is variable per patient.

Error Msg 6522, Level 16, State 1 Receives When Call The Assembly From Store Procedure To Create A Text File And To Write Text

Jun 21, 2006

Hi,
I want to create a text file and write to text it by calling its assembly from Stored Procedure. Full Detail is given below

I write a code in class to create a text file and write text in it.
1) I creat a class in Visual Basic.Net 2005, whose code is given below:
Imports System
Imports System.IO
Imports Microsoft.VisualBasic
Imports System.Diagnostics
Public Class WLog
Public Shared Sub LogToTextFile(ByVal LogName As String, ByVal newMessage As String)
Dim w As StreamWriter = File.AppendText(LogName)
LogIt(newMessage, w)
w.Close()
End Sub
Public Shared Sub LogIt(ByVal logMessage As String, ByVal wr As StreamWriter)
wr.Write(ControlChars.CrLf & "Log Entry:")
wr.WriteLine("(0) {1}", DateTime.Now.ToLongTimeString(), DateTime.Now.ToLongDateString())
wr.WriteLine(" :")
wr.WriteLine(" :{0}", logMessage)
wr.WriteLine("---------------------------")
wr.Flush()
End Sub
Public Shared Sub LotToEventLog(ByVal errorMessage As String)
Dim log As System.Diagnostics.EventLog = New System.Diagnostics.EventLog
log.Source = "My Application"
log.WriteEntry(errorMessage)
End Sub
End Class

2) Make & register its assembly, in SQL Server 2005.
3)Create Stored Procedure as given below:

CREATE PROCEDURE dbo.SP_LogTextFile
(
@LogName nvarchar(255), @NewMessage nvarchar(255)
)
AS EXTERNAL NAME
[asmLog].[WriteLog.WLog].[LogToTextFile]

4) When i execute this stored procedure as
Execute SP_LogTextFile 'C:Test.txt','Message1'

5) Then i got the following error
Msg 6522, Level 16, State 1, Procedure SP_LogTextFile, Line 0
A .NET Framework error occurred during execution of user defined routine or aggregate 'SP_LogTextFile':
System.UnauthorizedAccessException: Access to the path 'C:Test.txt' is denied.

XML Format File For Bulk Insert Of Text File With Fixed Length Columns

Jan 2, 2008

Hey All,

Similar to a previous post (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=244646&SiteID=1), I am trying to import data into a SQL Table.

I am trying to program a small application that will import product data obtained through suppliers via CD-ROM. One supplier in particular uses Fixed width colums, and data looks like this:




Example of Data

0124015Apple Crate 32.12

0124016Bananna Box 12.56

0124017Mango Carton 15.98

0124018Seedless Watermelon 42.98
My Table would then have:
ProductID as int
Name as text
Cost as money

How would I go about extracting the data with an XML Format file? I am stumbling over how to tell it where to start picking up data for a specific column.
Is there any way that I could trim the Name column (i.e.: "Mango Carton " --> "Mango Carton")?

I don't know if it makes any difference, but I've been calling SQL from my code by doing this:




Code in C# Form

SqlConnection SqlConnection = new SqlConnection(global::SQLClients.Properties.Settings.Default.ClientPhonebookConnectionString);
SqlCommand cmd = new SqlCommand();

cmd.CommandType = CommandType.Text;
cmd.CommandText = "INSERT INTO PhonebookTable(Name, PhoneNumber) VALUES('" + txtName.Text.ToString() + "', '" + txtPhoneNumber.Text.ToString() + "')";
cmd.Connection = SqlConnection;

SqlConnection.Open();
cmd.ExecuteNonQuery();
SqlConnection.Close();
RefreshData();
I am running Visual Studio C# Express 2005 and SQL Server Express 2005.



Thanks for your time,


Hayden.

Read Text File From Flat File Connection Manager SSIS

May 13, 2008

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);

}

Delete 2nd Transaction Log File

Feb 9, 2005

Hello
We have a SQL Server 2000 database with 2 transaction log files.
The 2nd file was created when we were running out of disk space and the person creating it was not familiar with the dbcc shrink command.

I now want to get rid of the 2nd log file. I ran the following steps with no success:

DBCC SHRINKFILE ('Log_file', EMPTYFILE )
--Message: Cannot shrink log file 3 (log_file) because all logical log files are in use.

ALTER DATABASE db1 REMOVE FILE 'Log_file'
--Message: The file 'Log_file' cannot be removed because it is not empty.


There are no users or open transactions in the database. I have also tried sp_detach_db and sp_attach_single_file_db but that does not work either as the database attaches both the transaction logs back.

Please advise.

Thanks

Nina
