Ivan,

After some experimentation it seems like using Stream Blobs makes no
difference. In fact, regardless of segment size, etc. the string
function will only work on ~1100 bytes inclusively. Seems like the only
hope is finding some TEXT BLOB UDF library that I can run (or at least
compile) on both Windows and Solaris. Unfortunately, I don't have time
to write my own in C/C++.

Cheers,

R.

There are several solutions. E.g.

- Use UDF instead of LIKE operator

- Use streamed blobs instead of segmented ones.
