Zusammenfassung:The invention provides an early warning method for a database execution plan, and the method comprises the steps: firstly obtaining the current operation information of the database execution plan, and the current operation information comprises the current operation time and the current operation state parameters; and calculating a current early warning threshold value corresponding to the current operation state parameter according to the current operation time. And finally, according to the calculated current early warning threshold value, judging the operation condition of the database execution plan, specifically judging whether the current operation state parameter and the current early warning threshold value conform to a preset relationship, and if the current operation state parameter and the current early warning threshold value conform to the preset relationship, sending out early warning information. The early warning information indicates that the database execution plan runs abnormally. The inve
