Disclosed in the embodiments of the present application are an execution plan analysis method and apparatus for structured query language (SQL), which method and apparatus are used for improving SQL execution plan analysis efficiency. The method in the embodiments of the present application comprises: a computing device determining an object function of a target database, wherein the object function comprises structured query language (SQL) statements that have been modified on the basis of restructuring logic, and the restructuring logic is used for identifying, in an execution plan, data manipulation language (DML) statements in the object function; the computing device generating an execution plan on the basis of the object function, wherein the execution plan is used for indicating performance evaluation metrics corresponding to one or more DML statements invoked in the object function; and the computing device displaying a performance analysis result corresponding to the execution plan, wherein the performance analysis result is used for identifying, from among the one or more DML statements, a DML statement the performance evaluation metric of which is lower than a threshold value.

The embodiment of the invention provides an information pushing method and device, equipment and a computer storage medium. The method comprises the steps of obtaining interest attribute information corresponding to a to-be-pushed object, wherein the interest attribute information comprises at least one of associated image information, object brand information, object function information and object style information; based on the interest attribute information, a pushed object corresponding to the to-be-pushed object is determined, and the similarity between the pushed object and the to-be-pushed object is larger than or equal to a preset threshold value; based on the interested crowd corresponding to the pushed object, determining a target pushing crowd corresponding to the to-be-pushed object; and pushing information to the target pushing crowd based on the to-be-pushed object. In the embodiment, the similar objects are effectively determined through the interest attribute information, the target pushing crowd is determined based on the interested crowd corresponding to the similar objects, and then the information is pushed to the target pushing crowd, so that the quality and effect of the information pushing operation are effectively ensured.

A data object definition and registration method includes invoking a user interface and placing a screen in the data object creation user interface. The method further includes selecting a data object in the user interface for association with different functions exposed by an application programming interface (API) of an application, the data object including one or more data elements and associated ones of the different functions. The method yet further includes associating in the user interface the data object with an external data object function defined separately from the selected data object as an event processible by an event handler, the association including reference to the one or more data elements and adding a control to the screen for the external data object function. Finally, the method includes registering the external data object function with an event handler.

Embodiments of the present application disclose a method and device for analyzing an execution plan of a structured query language (SQL), which are used for improving the analysis efficiency of the execution plan of the SQL. The method comprises the following steps: a computing device determines an object function of a target database, the object function comprising a structured query language (SQL) statement modified based on a reorganization logic, the reorganization logic being used for identifying a data manipulation language (DML) statement in the object function in an execution plan; the computing device generates an execution plan based on the object function, the execution plan being used for indicating a performance evaluation index corresponding to one or more DML statements in the object function; and the computing device displays a performance analysis result corresponding to the execution plan, the performance analysis result being used for identifying a DML statement whose performance evaluation index is lower than a threshold value in the one or more DML statements.
