Fixed SELECT with grouping on BLOB columns not to return incorrect BLOB info. Grouping, sorting and distinct on BLOB columns will not yet work as expected (probably it will group/sort by the first 7 characters in the BLOB). Grouping on formulas with a fixed string size (use MID() on a BLOB) should work.
When doing a full join (no direct keys) on multiple tables with BLOB fields, the BLOB was garbage on output.
Fixed DISTINCT with calculated columns.
