一个内存数据库的源代码这是服务器端还有客户端

# detect empty ranges
b := bat.new(:void,:int);
s1:= algebra.select(b,80,90);
s2:= algebra.select(b,90,80);
s3:= algebra.select(b,80,80);
s4:= algebra.select(b,80,80,true,true);
s5:= algebra.select(b,80,80,false,true);
s6:= algebra.select(b,80,80,true,false);
s7:= algebra.select(b,80,80,false,false);
optimizer.pushranges();
mdb.list();
