SQL & PL/SQL :: Unzipping The File In BLOB Column?
Apr 9, 2012I am trying to extract the BLOB column in Oracle Apex and show the contents of it as a popup message.
The files which are stored in the blob column are being zipped using windows zip function in Perl and being inserted in the dataabse using some perl program as follows,
my $zip = Archive::Zip->new();
my $zipfile = $zip->addFile( @$_->[1] ,basename(@$_->[0]));
While extracting the blob column we are using the utl_compress.lz_uncompress_extract() to extract the uncompressed version of file, but we are getting the following error as
"ORA-29294: A data error occurred during compression or uncompression".
I even tried the solution as mentioned in oracle forum

Calculate Size Of Table With BLOB Column
Feb 5, 2007when trying to calculate the occupied space for a table, I'm using DBA_SEGMENTS, which works fine as long as the table does not have a BLOB column.
As far as I can tell, the size of the BLOB data is stored with the SEGMENT_TYPE = 'LOBSEGMENT', but I cannot find a view that tells me which DBA_SEGMENT row belongs to the BLOB column in the table I'm checking.
To give you an example:
select sum(BYTES)
from DBA_SEGMENTS
where owner = user
and segment_name = 'MY_TABLE'
group by SEGMENT_NAME
returns 262144
running:
SELECT sum(length(blob_column))
FROM my_table
returns 821333
There are entries in DBA_SEGMENTS for my user with the type LOBSEGMENT, but I cannot find a way to map the correct DBA_SEGMENTS row to the table I am checking.
I'm using Oracle 10.2.0.3.0 on Redhat
