摘要：Techniques for scoring and comparing query execution plans are provided.Predefined parameter types are identified in query execution plans and predefinedweighted values are assigned to any identified parameters within the query execution

plans. The weights are summed on a per processing step bases and the sum of theprocessing steps represents a total score for a particular query execution plan. The totalscores or individual step scores from different query execution plans can then becompared or evaluated against one another for optimization and problem detectionanalysis.
