Update of /cvsroot/monetdb/sql/src/include
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv23009/src/include
Modified Files:
sql_list.h sql_relation.h
Log Message:
Many fixes
changed how we handle selections over multiple columns of a single table
(should solve the preformance problem reported by Venks)
added a way to bulk request sequence numbers. When loading (copying) data
into tables which have a auto_increment (or alike) column lots of time
was spend in the many calls to get all the sequence numbers (observed a
performance in crease of about 10x when loading pieces of 100K rows)
added support for TINYINT (we map this too 'bte')
improved mapping functions onto the same signature too improve cached
function reuse
