Byars was close to Edgar . When specifying merge sort operators , the current operator and both referenced operators must return boolean ; the SORT1 operator must have both input datatypes equal to the current operator 's left argument type , and the SORT2 operator must have both input datatypes equal to the current operator 's right argument type . Along with experts in knowledge , you need expert teachers . What this means is that a join using " = " between interval fields would yield different results if implemented as a hash join than if implemented another way , because a large fraction of the pairs that should match will hash to different values and will never be compared by the hash join . Develop and maintain positive and open channels of communication especially with your cooperating teacher and college supervisor . But this is after the rule system and will be discussed later .
