Class: WhereClauseCompoundExpression

An abstract class representing a compound expression consisting of either two or more sub-clauses combined with the AND or OR logical operator, or a single sub-clause negated with the NOT logical operator. Each sub-clause is either a fully-defined WhereClause (containing either a condition or a compoundExpression) or a ReferencedWhereClause (containing a subClauseId).

Examples

Example: WhereClauseCompoundExpression-01 AND

# Compound expression: (    ADAE.TRTEMFL EQ 'Y'
#                       AND ADAE.AESDTH EQ 'Y')
logicalOperator: AND
whereClauses:
- level: 2
  order: 1
  condition:
    dataset: ADAE
    variable: TRTEMFL
    comparator: EQ
    value:
    - Y
- level: 2
  order: 2
  condition:
    dataset: ADAE
    variable: AESDTH
    comparator: EQ
    value:
    - Y

Example: WhereClauseCompoundExpression-02 NOT with OR

# Compound expression: NOT (ADXX.VAR1 IN ('value 1','value 2') OR ADXX.VAR2 GT 37)
logicalOperator: NOT
whereClauses:
- level: 2
  order: 1
  compoundExpression:
    logicalOperator: OR
    whereClauses:
    - level: 3
      order: 1
      condition:
        dataset: ADXX
        variable: VAR1
        comparator: IN
        value:
        - value 1
        - value 2
    - level: 3
