List of nextAccessPath() Examples

Examples of nextAccessPath()

org.apache.derby.iapi.sql.compile.Optimizable.nextAccessPath()
Choose the next access path to evaluate for this Optimizable. @param optimizer Optimizer to use. @param predList The predicate list for this optimizable.The optimizer always passes null, and it is up to the optimizable object to pass along its own predicate list, if appropriate, when delegating this method. @param rowOrdering The row ordering for all the outer tables inthe join order. This method will add the ordering of the next access path to the given RowOrdering. @return true means another access path was chosen, false meansno more access paths to evaluate. @exception StandardException Thrown on error
