XP Compress Utils 1.0

XP Compress Utils will add to T-SQL capabilities to compress and decompress custom data using LZ compression algorithm.
There are the following extended stored procedures:
- xp_ZCreate begins the work;
- xp_ZAppend adds data to be compressed/decompressed to an internal buffer;
- xp_ZCompress compresses data and returns the result as a single row recordset of SQL IMAGE datatype;
- xp_ZDecompress decompresses data previously compressed by xp_ZCompress, and returns the result as a single row recordset of SQL IMAGE datatype;
- xp_ZClose finishes the work.
These procedures are provided by a dynamic-link library, xpCompressUtils.DLL.
