Method Detail

bindExpressionback to summary
pack-priv ValueNode bindExpression(FromList fromList, SubqueryList subqueryList, List<AggregateNode> aggregates) throws StandardException

Overrides org.apache.derby.impl.sql.compile.UnaryOperatorNode.bindExpression.

Bind this logical operator. All that has to be done for binding a logical operator is to bind the operand, check that the operand is SQLBoolean, and set the result type to SQLBoolean.

Parameters
fromList:FromList

The query's FROM list

subqueryList:SubqueryList

The subquery list being built as we find SubqueryNodes

aggregates:List<AggregateNode>

The aggregate list being built as we find AggregateNodes

Returns:ValueNode

The new top of the expression tree.
