LZ_UNCOMPRESS Functions and Procedures. This procedure accepts as input a RAW, BLOB or BFILE compressed string, verifies it to be a valid compressed value, uncompresses it using Lempel-Ziv compression algorithm, and returns the uncompressed RAW or BLOB result.. Syntax. This function returns uncompressed data as RAW:. UTL_ COMPRESS.LZ _UNCOMPRESS( src IN RAW) RETURN.
utl_ compress.lz _uncompress(src IN BLOB, dst IN OUT NOCOPY BLOB); TBD: Uncompress BFILE into BLOB Overload 5: utl_ compress.lz _uncompress(src IN BFILE, dst IN OUT NOCOPY BLOB) TBD : LZ_UNCOMPRESS_CLOSE: Closes and finishes a piecewise uncompress: utl_ compress.lz _uncompress_close(handle IN BINARY_INTEGER) See LZ_UNCOMPRESS_ EXTRACT .
Operational Notes. It is the caller’s responsibility to free the temporary LOB returned by the LZ* functions with DBMS_LOB.FREETEMPORARY call.; A BFILE passed into LZ_COMPRESS* or lZ_UNCOMPRESS* has to be opened by DBMS_LOB.FILEOPEN.; Under special circumstances (especially if the input has already been compressed) the output produced by one of the.
UTL_ COMPRESS.LZ _UNCOMPRESS( src IN BLOB, dst IN OUT NOCOPY BLOB); This function returns a temporary BLOB for the uncompressed data: UTL_ COMPRESS.LZ _UNCOMPRESS( src IN BFILE) RETURN BLOB; This procedure returns the uncompressed data into the existing BLOB(dst). The original dst data will be overwritten.

Oracle’s documentation for the UTL_ COMPRESS package is sparse in terms of showing a full-scale example . Sparse is not even the correct word here. Nonexistent is a better descriptor for UTL_ COMPRESS documentation. A MetaLink note (249974.1) shows two examples and various pages on the Internet can be searched.
Hi Sathya, Thanks for the reply. Please see Update 1 of example of what I want to get. In the one of the front end of the application, of which I cannot access codes, it does display string correctly. We are creating another front end for that application, and I can’t extract the values of some blobs correctly. Thank you. – Jemru Jun 18 ’14 …
10/4/2016 · The examples provided from links are good but here by clob is having 3 text files. now if I need to implement the logic what was suggested then a new function or procedure has to be written where as I was trying to use the existing function on the code.
For example it failed for blob with a size of 23327159 bytes (unizpped size is 23367907 bytes) I use Toad to run : SELECT zlib_decompress( BLOB_COLUMN ) FROM MYSCHEMA.MYTABLE WHERE ID_COLUMN=123 and it never end, I’m forced to close an unresponsive Toad. Oracle 11.2.0.4 Latest Toad version Thanks for any help.
