Manual Exporting of BLOB specific table to text file

Hi,
Our application is having 60000 record in a BLOB specific table.
My requirement is to export the entire table data to text files .
When I tried converting BLOB to sting and writing to file, it took almost 3 mins for 100 records, if so, will take so much of time in exporting data from BLOB specific table.
I am using the following logic,
byte[] bdata = blob.getBytes(1, (int)blob.length());
String data1 = new String(bdata);
buffer.append(data1);
Can anyone please tell me how can I speed up the operation.

Welcome to the forum!
If you are looking for a pure Java solution you should post this question in the JDBC forum.
https://forums.oracle.com/forums/category.jspa?categoryID=288
Unless your BLOB data is located inline you are going to use Oracle to read 60,000 files, one at a time, and then use Java to write 60,000 files one at a time.
That will be a very slow process.
Also - your Java code is only going to read the LOB locator and inline BLOB data since you are not getting and processing the actual stream.
See 'Reading and Writing BLOB, CLOB and NCLOB Data' in the JDBC Dev Guide for details

Export data from a table to text file using srcipt task

Hi
i am new to SSIS
i have to export data from a table and append it into a existing file through SSIS script task
please help
Thanks
Umesh

Hi Umesh,
The data structure of the source table and the structure of the destination file are the same, right? Is the destination file a flat file? Do you have to do it through Script Task? If the destination file is a flat file, this can be done easily by using
the stock tasks/components other than .NET code. In the Data Flow Task, we choose the appropriate source adapter (such as OLE DB Source or ADO.NET Source) to extract data from the source table, perform transformation if necessary, and then load to the destination
file via a Flat File Destination. When setting up the Flat File Destination, uncheck the “Overwrite data in the file” option so that the extracted data will be appended to the existing file.
If you need to implement it through Script Task/Component indeed, you may benefit from the following code examples:

http://stackoverflow.com/questions/8467326/add-header-and-footer-row-flat-file-ssis
If you need further help about the script, I suggest that you ask a new question in .NET forums where you can get more dedicated support:

Exporting list of tables to text files?

Anyone have solution for exporting list of SQL tables to text files?
My goal is to have a flexible/dynamic way to export sql tables to text files that is executed via a sql job. I plan on having a configuration table that has sqltablename, fieldstoexclude (maybe fieldstoinclude - not decided), path, filename, includeheader,
delimiter. So the SSIS package will query the configuration table and that will be the loop. One text file for each configuraton.tablename row.
Does anyone have an already built solution that they can share? I have seen some with vb script and am not opposed, but would like to have a strictly SSIS package that uses SQL queries for the solution.

Try using this as your query (Remember to set the database you want to use first:
DECLARE @tableBuilder TABLE (dSQL VARCHAR(MAX))
DECLARE @tableString VARCHAR(100), @newTableString VARCHAR(100), @columnString VARCHAR(MAX), @dSQL VARCHAR(MAX) = ''
DECLARE tableBuilder CURSOR FOR
SELECT
'CREATE TABLE '+d.name+'.'+t.name ,
c.name + ' ' +
CASE
WHEN st.NAME IN ('float','image','text','uniqueidentifier','date','time','datetime2','datetimeoffset','tinyint','smallint','int','smalldatetime','real','money','datetime','smallmoney','bigint','bit','hierarchyid','timestamp','xml','geometry','geography','sql_variant','sysname') THEN st.name
WHEN st.name IN ('decimal','numeric') THEN st.name + '(' + CONVERT(VARCHAR,c.precision) + ',' + CONVERT(VARCHAR,c.scale) + ')'
WHEN st.name IN ('nvarchar','nchar','char','varbinary','varchar','binary','ntext') THEN st.name + '(' + CONVERT(VARCHAR,c.max_length) +')'
END + ','+ char(13)+CHAR(10)
FROM sys.tables t
LEFT OUTER JOIN sys.extended_properties ep
ON t.object_id = ep.major_ID
AND ep.name = 'microsoft_database_tools_support'
INNER JOIN sys.columns c
ON t.object_id = c.object_id
INNER JOIN sys.systypes st
ON c.system_type_id = st.xtype
INNER JOIN sys.databases d
ON DB_ID() = d.database_id
WHERE ep.name IS NULL AND is_ms_shipped = 0
ORDER BY t.name, c.column_id
OPEN tableBuilder
FETCH tableBuilder INTO @tableString, @columnString
WHILE @@FETCH_STATUS <> -1
BEGIN
IF @tableString <> @newTableString
BEGIN
SET @dSQL = @newTableString + char(13)+CHAR(10) + ' (' + char(13)+CHAR(10) +LEFT(@dSQL,LEN(@dSQL)-3) + char(13)+CHAR(10) + ' )'
INSERT INTO @tableBuilder ( dSQL ) VALUES (@dSQL)
SET @dSQL = ''
END
SET @dSQL = @dSQL + ' ' + @columnString
SET @newTableString = @tableString
FETCH tableBuilder INTO @tableString, @columnString
END
CLOSE tableBuilder
DEALLOCATE tableBuilder
SELECT * FROM @tableBuilder
Export the results of that as you like.

How do I export/import keyboard shortcuts to a text file

How do I export/import keyboard shortcuts to a text file?
It would be nice to export them, edit and/or add to them in a text editor on my iMac, then import them back into iPhone and iPad.

You can backup the bookmarks to a file, then copy that file to the new computer and import them, for details see [[Backing up and restoring bookmarks]].
You can copy more than just the bookmarks. The user data, such as bookmarks and passwords, are stored in the profile folder. You can copy the data manually by copying the contents of the profile folder, for details see [http://kb.mozillazine.org/Profile_backup Profile backup - MozillaZine Knowledge Base] or [[Backing up your information]].
There are some add-ons and utilities that can make this process easier. The first one is the [https://addons.mozilla.org/en-US/firefox/addon/2109/ FEBE] add-on which can be used to copy a profile. Another option is the free [http://mozbackup.jasnapaka.com/ MozBackup] utility.

Hi,
After upload modify the code like below. Also change the file name as some one suggested already. If u are still facing problems then check in debug mode what is happening after FM call.
CALL GUI_UPLOAD FM.
IF sy-subrc EQ 0
IF NOT itab[] IS INITIAL.
MODIFY ZABPSP_01 FROM TABLE itab.
WRITE : / ' UPLOAD SUCCESS ' .
ELSE.
WRITE 'No data in file'.
ENDIF.
ELSE.
WRITE 'Upload failure'.
ENDIF.

How to export report to excel and to text file in previewer

How to export report to excel?
And, it takes long time for generate report to rtf or pdf file in previewer.
How to speed up the process? or, it's better generate report to text file directly by Run_product?
Please help!

You can generate report to tab delimite format that can be imported to excel.
As for the performance question, because reports can't specify what format when you run against previewer, so I don't know what previewer you are talking about. Generate to file is always faster than to your application previewer (assume) because you have one more step after output generated in the file: read from file and render it. Depends on the render and size of the output, it may have significant performance difference.
Thanks,

Write to a specific line in text file

In Mike's example, you cna change the constant 2 to a control which allows ytou to select which line to write to.
2 meaning the third position becasue indexing starts at 0.

Find and edit specific line in text file?

Hello I want to read a text file that could look in some different ways since the user choose file from a list. I then want to igonre all the lines that begin with a special character, for example %. I then want to find all the lines "words" that begin with TRY for example and put those "words" in a string or array. If there is one line that contains TRY100 and anoter line that contains TRY200 I want to find those words and display them. How do i do this?

First you read the entire file. Use the Read Text File. Right-click on it and select the option to Read Lines. The the count to read to -1 (read all). You will now have an array of strings, one item for each line of your file.
Now you need to play the filter game. I recommend using FOR loops with Autoindexing tunnels. Assuming you are using 2012 or later, have the output autoindexing tunnels use the conditional tunnel.
Give this a try and see where you can go. Post back with what you have tried and tell us where you are stuck.

Problem with pasting table into text file as text. 09 is different from 08?

Okay, here's what I'm doing. I've got a table in Numbers which I want to make into a table on a web page. Here's what used to work with Numbers '08 and OS 10.5:
Select cells. Copy.
Open TextEdit.
Paste and Match Style.
Make Plain Text
Save As (filename)
Open PageSpinner
Go to Table Assistant and Insert File (filename)
Now I have a new computer, running 10.6 and Numbers '09. And when I insert the file as a table into PageSpinner, I've got a special character littered throughout. Specifically, line breaks seem to be replaced with delete characters (the right-pointing pentagon with an x in it).
So what has changed, and how can I cope?
