ResolveBinaryArithmetic

object ResolveBinaryArithmetic extends Rule[LogicalPlan]

For Add: 1. if both side are interval, stays the same; 2. else if one side is date and the other is interval, turns it to DateAddInterval; 3. else if one side is interval, turns it to TimeAdd; 4. else if one side is date, turns it to DateAdd ; 5. else stays the same.

For Subtract: 1. if both side are interval, stays the same; 2. else if the left side is date and the right side is interval, turns it to -r); 3. else if the right side is an interval, turns it to TimeSub; 4. else if one side is timestamp, turns it to SubtractTimestamps; 5. else if the right side is date, turns it to DateDiff/SubtractDates; 6. else if the left side is date, turns it to DateSub; 7. else turns it to stays the same.

For Multiply: 1. If one side is interval, turns it to MultiplyInterval; 2. otherwise, stays the same.

For Divide: 1. If the left side is interval, turns it to DivideInterval; 2. otherwise, stays the same.
