Issue With Importing Paradox Blob Data
Sep 11, 2006
Hello,
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)
description char(120)
image blob
the ms-sql import wizard sees
id char(20)
description char(20)
I find this very odd, but I do need a solution. Any Ideas?
TY

I have a Paradox file which has 270 thousand records. If I open this db file through a paradox viewer it shows the correct number of rows.
I have an SSIS package which is suppose to read this db file and insert it into the SQL 2005 table. But when I execute this package it goes into a loop, reading the file over and over again. The package fails after inserting some 10 million rows giving the error msg 'Not enough space on temporary disk'.
On examing the data transfered into SQL there are duplicate rows.
I also used the import export wizard (thinking there might be some error in Package code) provided by SQL to transfer the data from .db to SQL but it has the same result(goes in a loop).
I would appreciate any help in this problem. Let me know if you have any other questions.
Thanks

Dear all -
iam facing a problem to insert data to paradox table by using OLE DB Destination ,
Briefly i built a simple data flow the has OLE DB Source from paradox Table1 and it linked to OLE DB Destination for another Paradox Table2 (i use query to get the table2 data in OLE DB Destination because it refuse to get data Directly) .
The problem that when i start debugging an error raise as the following:
Error: 0xC0202009 at Data Flow Task 1, OLE DB Destination [554]: An OLE DB error has occurred. Error code: 0x80040E09.
Error: 0xC0047022 at Data Flow Task 1, DTS.Pipeline: The ProcessInput method on component "OLE DB Destination" (554) failed with error code 0xC0202009. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
Error: 0xC0047021 at Data Flow Task 1, DTS.Pipeline: Thread "WorkThread0" has exited with error code 0xC0202009.
i hope someone help soon because i need to handle this problem as soon as possible

Does 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

Hi, I have to migrate an oracle database over to SQL Server 2005. One of the tables has PDF files stored as BLOB. All the ORACLE providers in SSIS do not support BLOB column. What can I use or how can I get the PDF files into my SQL table? The SQL column can be either IMAGE or VARBINARY(MAX).
Thanks,
Les

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)

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.
10/05/2007 16:52:53,Server,Unknown,Error: 4014<c/> Severity: 20<c/> State: 1.
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).
Best Regards,
Imre

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.

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?

A little background on what I am trying to achieve first. We are moving to Azure virtual machines and we will have 8 disks on the SQL Server box. I am adding more files to the primary file group and each file will go on its own drive. I am then rebalancing data across these files by rebuilding all of the indexes on the tables which is working fine. No problems so far all is good.
I now have an additional problem. If there is a lob or blob column on the table, rebuilding the clustered index and all the non clustered indexes doesn't rebalance the blob or lob data across the disks such as it does with in row data.
I cannot find any articles on rebalancing lob or blob data because all the articles say to move to a new file group. I do not want a new file group, I just want to use the primary file group where the data already resides, and just redistribute it evenly in the same way that I can in row data which is working fine.
One solution I thought about was to BCP data out of the table, truncate the table and then BCP back into the table which I imagine would have the desired effect of distributing the data evenly over the files.

hi all,
The PATINDEX function is not working with the image datatype in SQL Server.
The books online says that you can use PATINDEX with the image datatype.
Unfortunately it seems to be big lie.
How can I get the functionality of PATINDEX worked.
This is how I placed my SQL Query
declare @p binary(16)
select @p =0xFFFFF30A000000008400000001000000
select patindex('%DEFG%',image) from image where textptr(image) = @p
The error I am getting was
Server: Msg 288, Level 16, State 1, Line 4
The PATINDEX function operates on char, nchar, varchar, nvarchar, text, and
ntext data types only.
Why this is not working, according to Books online
Thanks for your time
bye

Hello,I've the following problem. I've to read out the data of a customapplication. I think (I'm not sure) this application is using aParadox DB to store it's information. I don't know it exactly causeI'm not familar with paradox at all, but I've found files like *.db,*.mb, *.px, *.xg*, *.yg* !!!I need the infomation from this files to combine it with other datastored in SQL 2000. I'm tried DTS to import the Data but I've got an"Microsoft JET Database" Error telling me that the table could not befound or that the table has not the asumed format. It depends on which*.db File i try to open. Description: Error calling the OPENROWSETmethod on the provider.My Questions, are there some special drivers i need, not included inMS MDAC Components or must I use a complete Databaseserver in theBackgroud hosting the DB Files. My developer station has the customapplication NOT installed. The db files seems to have no password set.I've got the same error when using MS Access to import the data. Ionly set the path to the dictionary where the files are in but leaveusername and password blank.HOW TO GET THIS DATA OUT ???Thank youTony

I am updating a Sql Server 7.0 DB to Sql Server 2005 Standard
I have to update Sql Server tables with Paradox 4.5 (DOS) data,
with DTS in 7.0 this was no problem.
In Visual Studio I use the OLE DB Jet 4.0 driver with the extended property "Paradox 4.x"
The package runs well if there is no Memofield or the Memofield has only a few characters.
If there is an Memofield filled with more than 250 Characters the preview and the data flow faults.
If I use "DBASE IV" on a dBase-table there is no error, but the NTEXT-Field in Sql Server has only one character " "
What can I do to get Paradox-data with Memofields?
Other problem:
I am missing the OLE DB Jet 4.0 Data Source in the Import/Export-wizard in
Sql Server Management Studio.

I have been told, I will have to transfer some paradox data into sql server 2005.
What is the best way to do this? i.e. if SSIS can be used, then what will be the source? I ask because there does not seem to be a source for Paradox.
Any thoughts please?

I've been programming in Paradox since DOS, but one mail-order database is getting rather large (100K client records, and associated orders, etc).
Our client wants us to move to Filemaker. In fact he'd like to have a 3rd party write the programme and me maintain it. The current package has been written & maintained by myself, with an awful lot lot going on in the Object PAL code.
I already have a copy (legal) of SQL Server & 10 licences for Access, and think that's a better option to re-develop in (although I could do with some training in both).
What are the pros & cons for each app, and what would people recommend. I'm going to cross-post into Access, Paradox & Filemaker forums to get an equal view.
Thanks

Hi,
I'm trying to import a Paradox 8 db into SQL Server 2000 using DTS but the list of data sources in the connections dialog only caters for version 5.x or older. Does anybody know how to get the data source for v8?
If not, is there any other quick and efficient way to import a paradox 8 db as I have to import around 15 of them to do.

Hello All,
I know nothing.
I am helping a friend, current database Paradox 7.x, custom app as I am sure they all are. I wanted to convert this DB to SQL or Access(MS)I do not have Access, but I have SQL 2000. I used the import/ convert tools within SQL, looked good to me, no errors etc.
I thought life was good. Now try to view, look at the data the way
users could. In the SQL manager, I can see tables, and stored procs, and lotsa cool stuff. I try and install SQL client on a PC to view. It basically extends the Admin tools to the deskop PC. How do I use an SQL conversion to realize the needs of the user interface. I think I need what is called a front end. You can stop laughing now.....
Anyway what direction should I take
to update this antique, no support Paradox DB.
Thanks, Dan T

I've never really setup or used MS SQL Server (just a couple hours, oneday, several months ago). I think MS SQL Server has the ability to use"linked tables", like MS Access does. Is this correct? What I want todo is have an MS SQL Server setup, which compatible applications cantalk with, but I want the data to come from a Paradox database. I canuse any MS SQL version, whatever would work best. I'm not sure aboutthe Paradox version, I know it is an old DOS version. I can't justconvert the data to another format, because Paradox still needs to useit.I tried using MS Access before, with ODBC drivers it *should* be ableto work with the Paradox data. However, I ended up with lots of datacorruption. I'm hoping MS SQL Server may work better, and not corruptthe Paradox data everytime it is updated.
