Implements org.hibernate.hql.ast.tree.OperatorNode.getDataType.

Retrieves the data type for the overall operator expression.
public Node

Returns:

The left-hand operand
getLeftHandOperand()

Implements org.hibernate.hql.ast.tree.BinaryOperatorNode.getLeftHandOperand.

Retrieves the left-hand operand of the operator.

Retrieves the right-hand operand of the operator.
public void
initialize()

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

Performs the operator node initialization by seeking out any parameter nodes and setting their expected type, if possible.

Doc from org.hibernate.hql.ast.tree.OperatorNode.getDataType.

Retrieves the data type for the overall operator expression.

Returns:Type

The expression's data type.

Retrieves the right-hand operand of the operator.

Returns:Node

The right-hand operand

public void initialize() throws SemanticException

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

Performs the operator node initialization by seeking out any parameter nodes and setting their expected type, if possible.

mutateRowValueConstructorSyntaxback to summary
private void mutateRowValueConstructorSyntax(int valueElements)

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

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

Parameters
valueElements:int

The number of elements in the row value constructor list.
