Applies to:Oracle Database - Enterprise Edition - Version 10.1.0.2 to 126.96.36.199 [Release 10.1 to 11.2]
PL/SQL - Version 10.1.0.2 to 188.8.131.52 [Release 10.1 to 11.2]
Information in this document applies to any platform.
I am running into an error when rusing utl_compress.lz_uncompress to read and decompress compressed XML data from a BLOB column.
- Read the LOB
- decompress it
- load it into an XML table -- without extracting the data to disk
Attempts to read and uncompress the compressed XML using utl_compress.lz_uncompress, as shown in the below code, generates an error (error message follows PL/SQL code) during the uncompress operation.
The data in the BLOB column is a valid compressed file.
I am able to:
1) extract the BLOB data through SQL Developer by double clicking on the (BLOB) column
selecting "Download" -- and uncompressing the saved file with any of 7-Zip, Winzip, or Windows based compressed folder,
2) extracting the BLOB data with a java program and saving it to disk, then uncompressing with the previously mentioned tools.
