Changeset: 19cb4f961948 for MonetDB
URL: https://dev.monetdb.org/hg/MonetDB/rev/19cb4f961948
Modified Files:
sql/backends/monet5/rel_physical.c
Branch: pp_hashjoin
Log Message:
Also put a crossproduct with a base table into a 'ref' so that we can generate a
complete buildhash pp block for it, otherwise it causes a pp block to be started
in the (pseudo) "build hash" stage without an ending, which is then picked up
by the "probe" stage.
