Overrides org.hibernate.hql.internal.ast.tree.BinaryLogicOperatorNode.initialize.

Implements org.hibernate.hql.internal.ast.tree.OperatorNode.initialize.

Called by the tree walker during hql-sql semantic analysis after the operator sub-tree is completely built.
private boolean
isNodeAcceptable(Node rhsNode)

this is possible for parameter lists and explicit lists.

private void
mutateRowValueConstructorSyntaxInInListSyntax(int
The number of elements in the row value constructor list.
lhsColumnSpan, int rhsColumnSpan)

Mutate the subtree relating to a row-value-constructor in "in" list to instead use a series of ORen and ANDed predicates.

@Override
isNodeAcceptableback to summary
private boolean isNodeAcceptable(Node rhsNode)

this is possible for parameter lists and explicit lists. It is completely unreasonable for sub-queries.

mutateRowValueConstructorSyntaxInInListSyntaxback to summary
private void mutateRowValueConstructorSyntaxInInListSyntax(int lhsColumnSpan, int rhsColumnSpan)

Mutate the subtree relating to a row-value-constructor in "in" list to instead use a series of ORen and ANDed predicates. This allows multi-column type comparisons and explicit row-value-constructor in "in" list syntax even on databases which do not support row-value-constructor in "in" list.

For example, here we'd mutate "... where (col1, col2) in ( ('val1', 'val2'), ('val3', 'val4') ) ..." to "... where (col1 = 'val1' and col2 = 'val2') or (col1 = 'val3' and val2 = 'val4') ..."

Parameters
lhsColumnSpan:int

The number of elements in the row value constructor list.
