It is only used by SQL? and how to designation the optimiser？but when I write MAL,for example, i:=0; b:= "done"; barrier go:= true; c:=i+1; d:="step"; v:=d; io.print(v); i:=c; redo go:= i<2; exit go; io.print(b); optimizer.aliasRemoval();
the last optimizer.aliasRemoval() is used for optimizing? 2010/8/11 Fabian Groffen <fabian.grof...@cwi.nl> > On 11-08-2010 15:25:15 +0800, kun ren wrote: > > Recently,I am intersting in MAL optimize，and have read the manual of > the > > MAL optimize, but it is so long, Possible if we want to use mal optimize > ,we > > must degignation the optimize consideration, such as alias removal, > > constant expression,join path optimizer;And then I dedug the MonetDB,but > > default it don't use any optimize.so what do you think about the mal > > optimize? > > It is only used when you use SQL.
