DM Database Server 64 v8,创建表CREATE TABLE "A"."B"("C" NUMBER(38,0) NOT NULL,"D" NUMBER(38,0) NOT NULL,"E" NUMBER(38,0),"F" CHAR(24),CONSTRAINT "B_PKEY" NOT CLUSTER PRIMARY KEY("C","D")) STORAGE (ON "BIGTS",CLUSTERBTR).执行SQL语句： SELECT * FROM "A","B" WHERE ((C<=500) or (C=500 AND D< =100000)) ORDER BY "C","D".为什么不走索引，添加hint也无效
