Examples of org.eigenbase.rex.RexInputRef

org.eigenbase.rex.RexInputRef
Variable which references a field of an input relational expression.
Fields of the input are 0-based. If there is more than one input, they are numbered consecutively. For example, if the inputs to a join are
- Input #0: EMP(EMPNO, ENAME, DEPTNO) and
- Input #1: DEPT(DEPTNO AS DEPTNO2, DNAME)
then the fields are:
- Field #0: EMPNO
- Field #1: ENAME
- Field #2: DEPTNO (from EMP)
- Field #3: DEPTNO2 (from DEPT)
- Field #4: DNAME
So RexInputRef(3, Integer) is the correct reference for the field DEPTNO2.
