Convert Between ASCII And EBCDIC
May 5, 2006
I am working on a project that will be mimicking an existing interface that we have with one our our clients. That interface today sends EBCDIC packed fields. We do not want to introduce changes to the external clients interface file when we rebuild it in SQL 2005 Integration Services and I need to find out how I can take ASCII data and convert it to the host (mainframe) representation, which is what we currently provide to our external client using Integration Services.
Has anyone had to do this? If so, can I accomplish it natively with SSIS, or do I need to look to a third party vendor for a component?
Thanks,
John

I tried to setup a flat file data source that has code page 37 (EBCDIC)
Then I have a flat file destionation that is ASCII.
And inbetween I have tried several different data flow conversion tasks liked Data Conversion, and Derived Column. But I keep getting errors about different code pages.
I also tried to load the EBCDIC data into a SQL Server DB, and it complains about different code page.
Has anyone been able to do this with SSIS out of the box, without any extra components ?

I need to do EBCDIC to ASCII conversion in SSIS. The incoming data has packed decimal fields in it. Has anyone been able to convert packed EBCDIC decimal fields to ACSCII using SSIS?

All, I have to automatically grap a dbf or ascii file from my hard drive and then insert that into an already existing database table. Does anyone know how to do this? The only thing I can find is to do it manually from enterprise manager, but I need to automate this.Thanks in advance!

Is there any way to convert Unicode (NVarchar) to Ascii (Varchar)?
If I just use cast , the result will become ???.

OK gang here I am again. I've gotten the Packed decimals and standard 4-byte unsigned integers to work. NOW I'm stuck on 2-byte integers.
1. My file connection defines a 2 byte column of type DT_BYTES (2 bytes in and 2 bytes out)
2. My Data Conversion task is set to convert the 2 byte ByteStream to a 4 byte unsigned integer (if I try to convert to a 2 byte unsigned integer SSIS gives me a datatype conversion (not allowed) error at design-time
3. Data Conversion task throws error at run-time stating "The value could not be converted because of a potential loss of data."
4. How could I lose data going from 2 bytes TO 4 bytes ?
5. HOW do I get this value into my SQL Server int column ?
6. The HEX representation of this data looks exactly as the 4 byte column that works looks (0x00 0x01, 0x00 0x02, etc) only 2 bytes instead of 4
HELP ANYONE. I'm at my wits end with this. I've read in this newsgroup that "Microsoft won't be building data conversion utilities for every single data source know to man" (almost like we're asking for a converter for "Johns Personal DBMS"). Mainframe, COBOL, and DB2 are entrenched in many large industries with legacy systems some of us want to interface with (to make it easier for our users to get at that legacy data). Hard to do though when MS won't take the time to bridge the communications with MAJOR systems like Oracle, DB2, and COBOL. Bridging those 3 languages alone would take care of MOST of legacy interactions. This seems a bit shortsighted and unsupportive to those of us forced to deal with ancient systems.
PLEASE help me someone get past this last issue with 2 byte unsigned binary integers
Thanks for letting me rant.

Hello,
I'm trying to load en EBCDIC file with packed decimal in comp 3 into a SQL table.
I have been searching information in this forum in several threads and have downloaded a DLL from http://www.microsoft.com/downloads/details.aspx?familyid=0e4bba52-cc52-4d89-8590-cda297ff7fbd&displaylang=en
and so far I've been able to get the "UnpackDecimal Data Flow Transformation" to work ... sort of.
The problem is that in the destination table the decimals appear allways as NULL.
The destination decimal column type in the table is set as VARCHAR (I've tryed to set Integer with no success).
Any help on this will be apreciated. If you need more information please ask.
Thanks.

I have data arriving in fixed-width EBCDIC format. Each file contains one or more groups of records. Before and after each group there is a header/footer, which is not in the same layout as the records that it describes. Header, record and footer each have a different layout to the other but are consistent within themselves.
Thankfully the one thing header, footer and record layout have in common is their length, so at the moment, using the appropriate code page in the Flat File Connection Manager, I'm able to read all the columns as strings. The headers and footers just come through, albeit a bit weird looking, and I can filter them out with a conditional splt.
However, the header contains information that needs to be appended to each record in the group. Does anyone have any suggestions about how to achieve this? I'm trying to avoid developing a custom data source for this task but, if there's no other way, has anyone done it and do they have any tips?

Hi All,
I have a file with several columns in Comp-3.
I have downloaded the UnPack Decimal component and, as it needs byte stream (dt_bytes) as input, so I set up an appropriate Flat File Source columns.
But I get this error:
[Flat File Source [2201]] Error: Data conversion failed. The data conversion for column "DTCDC" returned status value 2 and status text "The value could not be converted because of a potential loss of data.".
[Flat File Source [2201]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "output column "DTCDC" (2250)" failed because error code 0xC0209084 occurred, and the error row disposition on "output column "DTCDC" (2250)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.
DTCDC is first of the columns packed. These are mostly date columns packed into 5 bytes - should be unpacked to normal SQL date.
I've tried different locale , as suggested in other threads, but it didn't help.
Can anybody help me with this issue how can I do it in (VB.NET script ,importing as String??).
Thanks in advance

Hi, how are you?
I generated a Data Flow Task where a OLE DB Source connects to a SQL Server and gets data from a table. The next step, writes a txt file with the information (Flat File destination).
All data is imported to txt fiel if this one is configured as Code Page: 1252 (ANSI - Latin I) in the connection manager for the flat file. But if I change Code Page: 500 (IBM EBCDIC - International) which is the one I need beacuse I have to imported in a mainframe, it doesn't work.
This is the error that I receive:
Code Snippet
TITLE: Package Validation Error
------------------------------
Package Validation Error
------------------------------
ADDITIONAL INFORMATION:
Error at Data Flow Task [Flat File Destination [31]]: The code page on input column "STATUS_CD" (1293) is 1252 and is required to be 500.
Error at Data Flow Task [Flat File Destination [31]]: The code page on input column "SRC_NUM" (1294) is 1252 and is required to be 500.
Error at Data Flow Task [DTS.Pipeline]: "component "Flat File Destination" (31)" failed validation and returned validation status "VS_ISBROKEN".
Error at Data Flow Task [DTS.Pipeline]: One or more component failed validation.
Error at Data Flow Task: There were errors during task validation.
(Microsoft.DataTransformationServices.VsIntegration)
Does any one knows how can I convert from ANSI to EBCDIC or what I have to configure so as to not receive that error messsage? Thanks for help and time.

Hello all,
I was trying to run a test to write a ebcdic file out with a comp - 3 number (testing this for other people) and have run into a problem writing the string out to the flat file destination. I have the following script component:
Code Block
' Microsoft SQL Server Integration Services user script component
' This is your new script component in Microsoft Visual Basic .NET
' ScriptMain is the entrypoint class for script components
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
Public Class ScriptMain
Inherits UserComponent
Public Overrides Sub CreateNewOutputRows()
'
' Add rows by calling AddRow method on member variable called "Buffer"
' E.g., MyOutputBuffer.AddRow() if your output was named "My Output"
'
Output0Buffer.AddRow()
Dim myByteArray() As Byte = {&H12, &H34, &H56, &H7F}
Output0Buffer.myByteStream = myByteArray
Output0Buffer.myString = "ABCD"
Output0Buffer.myString2 = "B123"
myByteArray = Nothing
End Sub
End Class
I have added myByteStream as a DT_BYTES length 4, myString as (DT_STR, 4, 37) and myString2 as (DT_STR, 4, 37) to the output 0 buffer.
I then add a flat file destination with code set 37 (ebcdic us / canda) with the corresponding columns using fixed width.
When i place a dataviewer on the line between the two the output looks as I expect ("0x12 0x34 0x56 0x7F", "ABCD", "B123"). However, when it gets to the flat file destination it errors out with the following:
Code Block
[Flat File Destination [54]] Error: Data conversion failed. The data conversion for column "myByteStream" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
If i increase the size of the byte stream (say, to 50) the error goes away but I am left with the string "1234567F" instead of the appropriate hex values. Any clues on how to go about this? I obviously don't care if it gets transferred to "readable" text as this is supposed to be a binary stream, thus the no match in target page seems superfulous but is probably what is causing the problems.
NOTE: this is relating to the following thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2300539&SiteID=1) in that I am trying to determine why these people are not seeing the "UseBinaryFormat" when importing an EBCDIC file (i see this fine when i use an ftp'd file, but it auto converts to ascii) with comp-3 values. I also see the "UseBinaryFormat" when I am importing a regular EBCDIC file which I create that has no import errors with zoned decimals.

What do I need to do to import Ebcdic file with comp3 packed data fields from mf into SQL Server? Is this possible? Do I need to go into advanced properties and change the data type? Or do I need to use data conversion task for the packed fields. Any advice or if somebody could point me to a sample script would be greatly appreciated.

Hello one and all,
I’m new to T-sql and need help understanding the CHAR() and ASCII functions.
I tried to run these commands to better understand them but I get the same results each time.
Here is the query with the char command
USE Northwind
SELECT FirstName + ' ' + LastName, + CHAR(13) + Address,
+ CHAR(13) + City, + Region
FROM Employees
WHERE EmployeeID = 1
Nancy Davolio
507 - 20th Ave. E.
Apt. 2A
Seattle WA
(1 row(s) affected)
Here is the same command without the char function.
USE Northwind
SELECT FirstName + ' ' + LastName, + address, + city, + region
from employees
where employeeID = 1
address city region
------------------------------- ------------------------------------------------------------ --------------- ---------------
Nancy Davolio 507 - 20th Ave. E.
Apt. 2A Seattle WA
(1 row(s) affected)
As you can see I get the same results back except for the column names being displayed.
Please help me understand this.
Thank you,
Eric Talley

I have an file I FTP onto the server using a FTP task in my DTS package. The problem I'm having is the FTP task downloads using binary format, whereas I need it to download using ascii format. Binary is causing characters in the file to change, and my import is failing.
Any idea on how to set it to download as ascii?

Hi
I am importing data from mainframe using DTS the problem is that I am getting some COMP fields from the mainframe these are compressed data fields that are used to reduce storage space on the main frame. Can some one please help me understand how we can use DTS to solve this problem that is decompress it before transferring to table in SQL server.
any code in scripting language to help decompress this datatype will be really appreciated.

Hi All,
I need to generate Ascii 7 bit flat file, based on data in db, using integration services, FTP task. Currently i am generating file with ansi-latin and then using the script task converting it to the ascii 7. File looks to be generated properly. But when the target system reads this, they complain that the file has junk charecters some thing like this. when i open it after generating the file it looks fine to me in DOS also. I dont know what is the target system and what OS is used by them. what cud be the issue for these junk charecters and is it possible that a Ascii 7 file generated by windows doesnt work in other OS? If the method i am doing to generate the ascii 7 is not currect then what is the best method for this?
ÿþH^@D^@R^@|^@1^@E^@N^@I^@N^@A^@|^@O^@|^@2^@0^@0^@6^@-^@0^@9^@-^@1^@3^@
PS: earlier i had generated a flat file using data export from Excel & that worked in the target system well. is there any difference in the file encoding generated by excel and integration services?
Please help me!!!!

I have a problem with alot of my SPs. All compile correctly but cause erroneous data due to IF statements begin ignored due to
characters (see below).
Example SP...
-- Opened within last 12 Months
IF @NEWACCIND = 1
BEGIN
EXECUTE usp_DFDX03_D0150_A4 @COSTALL OUTPUT
END
-- Accounts in Arrears in Current Quarter
Should look like ...
-- Opened within last 12 Months
IF @NEWACCIND = 1
BEGIN
EXECUTE usp_DFDX03_D0150_A4 @COSTALL OUTPUT
END
-- Accounts in Arrears in Current Quarter
I need to find all SPs with double
instance and manually replace. There are hundreds of SPs in total. I have tried
SELECTCOLID, ID
FROMSYSCOMMENTS
WHERECHARINDEX (CONVERT (VARCHAR(3), CHAR(13)+CHAR(13)), TEXT) > 0
but this also returns SPs containing 2 consecutive blank lines as well (which there are alot of due to formatting of T-SQL).
Really I need to distuinguish between
and new line which both appear to be CHAR(13)
Any one got any ideas
Thanks in advance

Thought I would share this since it caused me so much grief.
In some mainframe systems, some dates are stored as the string "00000000". In my SSIS package, I was trying to anticipate for this string, as well as any other combination of zeros (e.g., "000", "0000", etc), since I had already seen lots of dirty data in the flat file (like non-printing characters, etc).
So, what I tried to do was perform an integer conversion on the string and test if it was the equivalent of the numerical value zero:
Code Snippet
(DT_STR)[ColumnName] == 0 ? ....
Now, for some reason, that doesn't work, even though a similar operation in SQL does work:
Code Snippet
SELECT TOP 1 ISNUMERIC('00000000') FROM tableName
In the end, I had to resort to testing for a match on the literal string "00000000" and hope that no other dates came in as "000" or other variation. Fortunately, this has been true so far.
However, the moral of the story is, converting a series of zeros into a numeric zero, and testing against that, does not seem to work. I don't have a good explanation for why that is, but I would guess it has something to do with the limitation of the conversion function.
Happy integrating.

I've an issue with double-quotes in CSV file. One of the columns may contain this kind of value: "STATUS ""H"" "
I've got quote set to "
The file source fails on such records.
I found this thread and Scott tells us there that the file can't contain " in data.
Is this 100% correct?
I've got mutliple text columns and the pain is that I don't know which column might have these cases in future. To create a script means to write my own file parser for all files I use.
Any ideas?

Hi,
I'm working on a database conversion from Sybase to SQL Server 2005 and have hit a wall with a character conversion problem when reading non-ASCII characters (encrypted password string) via JDBC.
My application runs on Solaris and accesses a SQL Server 2005 database via the Microsoft JDBC driver. The server was unfortunately specified as having a SQL_Latin1_General_CP1_CI_AS collation at installation time, and the database being accessed has taken this default. After creation the data was migrated across via DTS.
The invalid character is a dagger '†'. When read over JDBC it is converted to a question mark '?'.
In my original environment a Sybase database was accessed via JDBC driver from Solaris and the correct value was returned. The Sybase database used Latin1_General_BIN as it's collation. By way of experimentation I have modified the default collation sequence within the SQL Server 2005 database, and created a new table to hold the password. I am then able to correctly return strings containing this character from within SQL Server Management Studio, but the same problem still exists when accessing it via JDBC.
I am not sure where to focus my investigation and would be grateful for any useful pointers/advice. To me it looks like it's a JDBC driver issue as with the change in collation it works from a non-JDBC client.
Many thanks
Alistair
