How do I use the GetBlobdata to get the string representation?
I have tried numerous version of Encoders thinking that
System.Text.Encoding.GetEncoding(Row.TextData.ColumnInfo.CodePage).GetString(b) (where b is the byte array returned by GetBlobData)
But this doesn't work. I have had to resort to converting the field in SQL, so I don't have to deal with blobdata.
I have a source DB that contains a BLOB which is really a bunch of text. I am trying to use SSIS to read this BLOB and stream the chars as text to a flat file which will later be FTP'ed to another server and reloaded as nvarchar records.
In my data flow task I have my source (SQL DB BLOB) and target (Flat File) of course...in between I am using a script component to try and convert the BLOB. Here is my code:
Dim intBlobLength As Integer = Convert.ToInt32(Row.denoteblob.Length)
Dim intFinish As Integer = intBlobLength - 1
Dim byteBlob(intFinish) As Byte
byteBlob = Row.denoteblob.GetBlobData(0, intFinish)
Row.outdenoteline. = byteBlob
Row.outdebtorrowid = Row.debtorrowid
I get a pipeline is to small error. I cant seem to adjust the size of the outdenoteline within the script componenet.
please help!

I am using OLE DB source component to read a blob data column from a table. Then I want to Pass this column to a script component,w hich in it's script task should be able to convert it to a string and send it as an email.

Please advise
hello all,
I am reading a file that contains textual data (formatted,e.g font=bold,font size=10 etc). After reading the file, i store the data read from the file to a table in Sql server 2005. But in the table, this data is stored like this:
daohORIGINAL TEXTm............
how can i just store the original text of the file in the table and get rid of these boxes? Or when i read this data from table, how to remove these boxes and get only the original text?
Thanks in advance.
I am using C# FileStream to read the file from disk. VS 2005
I tried using derived collumn it did not work. I also tried data conversion transformation which did not work.
Can any one suggest me some other method.
Thanks.
Trying to get a multi field grouping to print.

i am trying to take a field that has part of a date in it, so I have to parse it out as follows:
SUBSTRING(a1.Field1, 3, 2) + SUBSTRING(a1.Field1,5,2) + '20' + LEFT(a1.Field1,2)
This is because a date of 04/16/2014 will show as 160416 in the first part of the field I need to parse it out of, thus becoming 04162014.
From there I then need to convert this "date" into a legitimate SQL datetime type, so that I can then run a DATEDIFF to compare it to when the record was actually entered, which is a separate field in the table, and already in datetime format.
When I use the below statement, I am getting the message that, "Conversion failed when converting date and/or time from character string."
CAST((SUBSTRING(a1.Field1, 3, 2) + SUBSTRING(a1.Field1,5,2) + '20' + LEFT(a1.Field1,2)) as datetime)
I also tried CONVERT(datetime, (SUBSTRING(a1.Field1, 3, 2) + SUBSTRING(a1.Field1,5,2) + '20' + LEFT(a1.Field1,2)), and got the same message.
how I can parse that field, then convert it to a datetime format for running a DATEDIFF statement?

Dear Experts,Ok, I hate to ask such a seemingly dumb question, but I'vealready spent far too much time on this. More that Iwould care to admit.In Sql server, how do I simply change a character into a number??????In Oracle, it is:select to_number(20.55)from dualTO_NUMBER(20.55)----------------20.55And we are on with our lives.In sql server, using the Northwinds database:SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2)) as a_number,cast ( STR(r.regionid) as int ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2) ) as a_number,cast (STR(r.regionid,7,2) as numeric ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044Str converts from number to string in one motion.Isn't there a simple function in Sql Server to convertfrom string to number?What is the secret?Thanks

I need a solution for the following:
I have a field with datatype string, length 8, in the form yyyymmdd (f.e. 20070604).
Now I need to transfer this field into a field with datatype dt_DBDATE or DT_DBDATE.
I tried to perform this with a derrived column and type cast (DT_DATE) or (DT_DBDATE), but this does not work.
Any hint for me!!!

HI.
I'm having this problem.
I use Visual Studio's, integration project to load XML file into SQL Server. In the XML file, i have defined collumns as string. When i try to load XML file with parts defined in scheme as string, i get an error "cannot convert between unicode and non-unicode string data type.
Destinated collumns in SQL are defined as varchar and char.
Thanks for help
Hi,
I have spent countless number of hours trying to solve the issue, but to no vail. My problem is SSIS throws "cannot convert between unicode and non-unicode string data types" when i am try to transform data from DB2 to SQL Server 2005. And please note, i tried all possibilities like changing the destination field which is in SQL Server 2005 to nvarchar and also text. But so far no help. And i also looked at previous posts which did not help me either.
Thank You in advance.

View 4 Replies View RelatedDoes anyone have any experience of this type of data please? I have been asked to work on a project where it looks like we will be taking MS Office files and scanned images and storing them in a SQL 2000 db so that they can be aquired by a third party application. I am most intereested in the size of the records as the server may need upgrading, for space and performance.
I am also interested in how a BLOB record is created, is it a particular save process from Word / Excel etc or can you specify to import as a BLOB from a SQL script?
Any info welcomed as i really dont know where to start !!!
TIA
Hi all,It was my understanding (Please correct me if I'm wrong on this!) thatBLOB data actually reside on their own separate pages and a BLOB fieldonly holds a pointer to the location of the actual data, therefore theBLOB data per se would not get written to the log, only the pointerwould be written.If log shipping works by applying the transaction log to the standbydatabase, then what happens to the BLOB data?Related question, how does transactional replication work? Is it alsobased on the transaction log?TIA,Ellen
View 4 Replies View RelatedHi, I have to migrate an oracle database over to SQL Server 2005. One of the tables has PDF files stored as BLOB.

hi,
i learned that BLOB data types are out-row data by default, i think it means it will not store in the row of table, because the max-length of a col is 8KB.
but will the system store those BLOB data? and is there any way to specify where should it be stored, like tha Partition Schema.
i am using SQL Express, so i hope it works for express.(partition does not work for express)
1. How many blob data types can be defined in a table on SQL Server 7.0
2. What is the max size for a blob data type.
Hi,
I have a problem with writing BLOB data into type of 'image' field.
If the data size > ~280 MByte (< 2 GB) the operation failed.
It is appear on SQL Server 2000 and 2005 (MSDE and express also).
Detailes :
column type : image
Server : SQL Server 2005, version - 9.0.3042
technology : OLEDB, from C++ -> CDynamicAccessor
protocol for communication : TCP/IP
Size of the DB : ~3 MByte.
As I see the provider read partially (~267 943 936 byte if all is 280 MB) of data from my ISequentialStream.
Error of OLEDB:
DB_E_ERRORSOCCURED : 0x80040e21
[DBNETLIB][ConnectionWrite(send()).]
General network error.
SQL Server error log entries :
10/05/2007 16:52:53,Server,Unknown,A fatal error occurred while reading the
input stream from the network. The session will be terminated.

Entries of SQL profiler :
Error: 4002, Severity: 16, State: 4
The incoming tabular data stream (TDS) protocol stream is incorrect. The stream ended unexpectedly.
I used to set up the bug with contents of a ~350 MB .zip or .mdf file. Everyting is ok when the data <= ~250 MB.
I had ran MS Network Monitor on the server side and not found partially transmitted frames (but I use it on first time).
We try it on another machines, on another LAN with other BLOB (and the bug arised).
I had try 'named pipes' protocol for communication (and the bug arised).
I will be glad if somebody maintain that how can I found the origin of the bug (tools, log options, protokol settings etc.) or
I can present my simple test program (VC 2005 project) and its database (MS SQL 2005).

I have SQL Server 2000 and I'm trying to import data from a paradox v5 database. Everything has moved over fine but the data from the blob fields. When I use the import tool and try connect to a paradox blob field, the import wizard does not "see" the paradox blob field. here is and example.
If I have a table with the following fields.
id char(20)

image blob
the ms-sql import wizard sees
id char(20)

Hi! I tried to save some image data, but it get truncated at 8000 (the table column is defined as Image). I then wrote a converter to try ntext-datatype instead, but it gets truncated at 4000.
Error message:
System.Data.SqlServerCe: @3 : String truncation: max=4000, len=4168
The code uses only ADO entity framework for database access. Is there a way to store binary data larger than 8000 bytes? I am running SQL Compact 3.5 sp 1 BETA.

We are debating what is industry “best practice� for serving huge numbers of images in an industrial scale website. More directly, which approach produces the best performance and the best scalability? For example, how do sites like ebay, Amazon, and other large sites handle the millions or billions of images they must deal with?
Store as BLOB in sql server?
Store in /images folder and store url text into sql server?
We always assumed that the second approach is what most sites must do. But do they?
One developer on our team maintains that storing one million or more image files in a directory will most certainly result in poor performance, because the server must scan the directory, searching for the correct file, each time a web request is made. The directory is not indexed (?) so performance must eventually suffer.
Other developer counters that storing millions of images as BLOBs into sql server will result in poor performance and HUGE database. An additional layer of access (webserver to sql server, back to webserver, then to client) causes a delay and performance hit.
Who is right? What do the gurus as the world class sites do?
using sql 2008, trying to convert a string to int
Example
Table1 has a varchar which i want to cast to int
00125000000 to int 125000000
i used the following
cast(B.[Assessment] as int) as [USER1_01],
with the result 125000000
Table2 has the same field in a different format.
0.00125
i need to find a way to convert one of them so they both match. if i did a join and matched the fields.
I tried
cast (10000000000 * cast([USER1_01] as NUMERIC(6,6)) as INT) as [USER1_01]
but for some reason it dosent look like they match, although they look the same. maybe a type problem?
