VARCHAR And Binary Zeros
Jun 26, 2007
Hi
I'm using DB2 Connect to access an IBM DB2 database, and I'm trying to import a table, having one VARCHAR field, containing multiple binary zeros, to SQL Server.
My problem is the VARCHAR type in SQL Server is defined as a null-terminated string of characters. So everytime I retrieve one of these values, it gets truncated (the first binary zero becames the end of the string).
I've tried using the TEXT data type, replacing the 0X00 character as part of the select , and using the native and .net OLE DB provider with no luck.
If anyone has faced the same problem before, I would appreciate any help.
Thanks.

Hi.
There is a "text" file generated by mainframe and it has to be uploaded to SQL Server. I've reproduced the situation with smaller sample. Let the file look like following:
A17 123.17 first row
BB29 493.19 second
ZZ3 18947.1 third row is longer
And in hex format:
00: 41 31 37 20 20 20 20 20 31 32 33 2E 31 37 20 20 A17 123.17
10: 66 69 72 73 74 20 72 6F 77 0D 0A 42 42 32 39 20 first rowͺBB29
20: 20 00 20 34 39 33 2E 31 39 20 20 73 65 63 6F 6E 493.19 secon
30: 64 0D 0A 5A 5A 33 20 20 20 20 20 31 38 39 34 37 dͺZZ3 18947
40: 2E 31 20 74 68 69 72 64 20 72 6F 77 00 69 73 20 .1 third row is
50: 6C 6F 6E 67 65 72 longer
I wrote "text" in quotes because sctrictly it is not pure text file - non-text binary zeros (0x00) happen sometimes instead of spaces (0x20).
The table is:
CREATE TABLE eng (
src varchar (512)
)
When i upload this file into SQL2000 using DTS or Import wizard, the table contains:
select src, substring(src,9,8), len(src) from eng
< src ><substr> <len>
A17 123.17 first row 123.17 25
BB29 493.19 22
ZZ3 18947.1 third row 18947.1 35
As one can see, everything was imported, including binary zeros. And though SELECT * in SSMS truncates strings upon reaching 0x00's, still all information is stored in tables - SUBSTRINGs show that.
When i upload this file into SQL2005 using SSIS or Import wizard the result is following:
< src ><substr> <len>
A17 123.17 first row 123.17 25
BB29 4
ZZ3 18947.1 third row 18947.1 25
This time table is half-empty - all characters behind binary zeros in respective rows are lost.
I stumbled upon this problem while migrating my DTSes to SSIS packages. Do you think there is some workaround, or i need to turn on some checkbox or smth else could help? Please...

I'm using varchar as a datatype and my leading zeros are chopped-off once ther data reaches my Stored Proc. The table will allow me to store the values with leading zeros if I enter them manually, but I cannot insert them via ASP/StoredProc.
Any ideas would be awesome.

I need help converting a varchar field to binary.
I have a Data Control Task that has a OLE DB Source and corresponding OLE DB Destination Data Flow Task. In the referenced source table there exists a field defined as a varchar(12), in the corresponding destination table it is defined as a binary(12). How do I perform this conversion?
I tried inserting a Data Conversion Task and assigning the new data type as byte stream[DT_BYTES] and a Length = 12, but this was a bust. Output test is as follows:
Error: 0xC020901C at DFT - Windows, OLE_SRC - Windows [1]: There was an error with output column "Payload" (40) on output "OLE DB Source Output" (12). The column status returned was: "The value could not be converted because of a potential loss of data.".
Can anyone help me out here?

Server is SQL 2000
I have a table with 10 rows with a varbinary column
I wish to concatenate all the binary column into a single binary column and then write that to another table within the database. This application splits a binary file (Word or PDF document) into multiple segments (this is Column2 as below)
example as follows
TableA
Column1 Column2 Column3
aaa 001 <some binary value>
aaa 002 <some binary value>
aaa 003 <some binary value>
aaa 004 <some binary value>
aaa 005 <some binary value>
desired results in TableB
Column1 Column2
aaa <concatenated value of above binary columns>

I'm using a bit-wise comparison to effectively store multiple values in one column. However once the number of values increases it starts to become too big for a int data type.you also cannot perform a bitwise & on two binary datatypes. Is there a better way to store the binary data rather than int or binary?

I have looked far and wide and have not found anything that works to allow me to resolve this issue.
I am moving data from DB2 using the MS OLEDB Provider for DB2. The OLEDB source sees the column of data as DT_TEXT. I setup a destination to SQL Server 2005 and everything looks good until I try and run the package.
I get the error:
[OLE DB Source [277]] Error: An OLE DB error has occurred. Error code: 0x80040E21. An OLE DB record is available. Source: "Microsoft DB2 OLE DB Provider" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".
[OLE DB Source [277]] Error: Failed to retrieve long data for column "LIST_DATA_RCVD".
[OLE DB Source [277]] Error: There was an error with output column "LIST_DATA_RCVD" (324) on output "OLE DB Source Output" (287). The column status returned was: "DBSTATUS_UNAVAILABLE".
[OLE DB Source [277]] Error: The "output column "LIST_DATA_RCVD" (324)" failed because error code 0xC0209071 occurred, and the error row disposition on "output column "LIST_DATA_RCVD" (324)" specifies failure on error. An error occurred on the specified object of the specified component.
[DTS.Pipeline] Error: The PrimeOutput method on component "OLE DB Source" (277) returned error code 0xC0209029. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.
Any suggestions on how I can get the large string data in the varchar column in DB2 into the varchar(max) column in SQL Server 2005?

I am trying to create a store procedure inside of SQL Management Studio console and I kept getting errors. Here's my store procedure.
Code Block
CREATE PROCEDURE [dbo].[sqlOutlookSearch]
-- Add the parameters for the stored procedure here
@OLIssueID int = NULL,
@searchString varchar(1000) = NULL
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
IF @OLIssueID <> 11111
SELECT * FROM [OLissue], [Outlook]
WHERE [OLissue].[issueID] = @OLIssueID AND [OLissue].[issueID] = [Outlook].[issueID] AND [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
ELSE
SELECT * FROM [Outlook]
WHERE [Outlook].[contents] LIKE + ''%'' + @searchString + ''%''
END
And the error I kept getting is:
Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 18
The data types varchar and varchar are incompatible in the modulo operator.
Msg 402, Level 16, State 1, Procedure sqlOutlookSearch, Line 21
The data types varchar and varchar are incompatible in the modulo operator.
Any help is appreciated.

For the life of me I cannot figure out why SSIS will not convert varchar data. instead of using the table to table method, I wrote a SQL query so that I could transform the datatype ntext to varchar 512 understanding that natively MS is going towards all Unicode applications.
The source fields from Access are int, int, int and varchar(512). The same is true of the destination within SQL Server 2005. the field 'Answer' is the varchar field in question....
I get the following error
Validating (Error)
Messages
Error 0xc02020f6: Data Flow Task: Column "Answer" cannot convert between unicode and non-unicode string data types.
(SQL Server Import and Export Wizard)
Error 0xc004706b: Data Flow Task: "component "Destination - Query" (28)" failed validation and returned validation status "VS_ISBROKEN".

DTS used to be a very strong tool but a simple import such as this is causing me extreme grief and wondering of SQL2005 is ready for primetime. FYI SP1 is installed. I am running this from a workstation and not on the server if that makes a difference...
Any help would be appreciated.

Hi all,
I have a problem.
The SQL statement I have is like this
select * from table where (convert varchar(25),AMT) LIKE '%0%'
This causes all my data to appear instead of 1 only if I key 77 into the textbox because AMT is a currency type with 77.000.
So is there another way of solving this other than truncating off the zeroes?
If so feel free to assist me, your help is greatly appreciated.
Thanks.

Hi Folks,
I have a situation where I need to display an integer with leading zeros, with a defined length.
Example, 43 appears as 00043 when the length is 5 and 000043 when the length
is 6.
I tried using "=Format(Fields!DirID.Value.ToString)" with different variations to no avail.
Any ideas will be appreciated.

I have a table that contains a lot of demographic information. The data is usually small (<20 chars) but ocassionally needs to handle large values (250 chars). Right now its set up for varchar(max) and I don't think I want to do this.
How does varchar(max) store info differently from varchar(250)? Either way doesn't it have to hold the container information? So the word "Crackers" have 8 characters to it and information sayings its 8 characters long in both cases. This meaning its taking up same amount of space?
Also my concern will be running queries off of it, does a varchar(max) choke up queries because the fields cannot be properly analyzed? Is varchar(250) any better?
Should I just go with char(250) and watch my db size explode?
Usually the data that is 250 characters contain a lot of blank space that is removed using a SPROC so its not usually 250 characters for long.
Any insight to this would be appreciated.

I have an SSIS routine which uses a simple SQL select statement from a SQL Server 2005 database and then goes to a Flat File destination. The field (dischstatuscode) is a nvarchar(50) and it may contain data with leading zeros.
Code Snippet
Select DischStatusCode
from dbo.pm
...which returns:
01
23
37
05
04
41
When I open up the csv file produced by the SSIS routine, I see the following:

Going against a Sybase database using ODBC, the numeric data in the amount field (money)
drops all zero's to the right of a whole number when bringing it into MSQL 7. Example:
2,000.00 comes across as 2
2,001.00 comes across as 2,001.00
Has anyone a solution to this? What am I doing wrong? If I run a query against the SYBASE
database, everything looks fine. Once I bring it into SQL, I'm about 9,000,000 dollars off.
Thanks for any help you can offer.
