Abstract: The disclosure relates to a method and an apparatus for loading a picture. A target page element is obtained. A motion state of the target page element is obtained. A to-be-loaded picture carried by the target page element is obtained. The to-be-loaded picture is added to a to-be-loaded queue based on the motion state being a scrolling state. The to-be-loaded queue is configured to monitor the to-be-loaded picture based on a change of the motion state. The to-be-loaded picture is added to a loading state based on the motion state changing to a non-scrolling state.

Abstract: The disclosure relates to a method for controlling an operation list, including: obtaining a remaining space between a target operation item and a bottom of a display region, of a display of a device, when the target operation item is located at a preset position; obtaining a size of a current list viewport of the operation list; extending the size of the current list viewport based on the remaining space to generate an extended current list viewport; laying out the operation list based on the extended current list viewport to obtain a size of a next operation item of the target operation item; and determining a display position of the target operation item based on the size of the next operation item and the remaining space.

Abstract: A rendering method, rendering apparatus implementing said rendering method, an electronic device implementing said rendering method, and a storage medium implementing said rendering method includes: obtaining data of a page to be processed; extracting a plurality of page elements from the data of the page to be processed; obtaining content and a plurality of attributes of each page element of the plurality of page elements; generating a plurality of rendering object sets, each rendering object set corresponding to each page element based on the content and the plurality of attributes of the respective page element, each rendering object set including a plurality of rendering objects; generating a rendering tree based on a plurality of rendering object sets corresponding respectively to the plurality of page elements; and performing a rendering process based on the rendering tree.

Abstract: The disclosure provides a method for determining a location of a focus, an apparatus for determining a location of a focus, and an electronic device, and relates to the field of electronic devices. The method includes: obtaining a current location of the focus in an electronic device; determining a current page element located by the focus based on the current location of the focus; obtaining an instruction for controlling the focus; obtaining a movement direction of the focus based on the instruction; obtaining a layout direction of the current page element; returning to a parent page element of the current page element in response that the movement direction of the focus is inconsistent with the layout direction; and determining the location of the focus in the parent page element.

Abstract: An SQL procedure deployment system deploys a query procedure comprising a procedural logic component and a database request component from a source system to a target system. At generation of the query procedure, the system generates a query procedure source code, a symbol table, and an encapsulated optimization results to regenerate run-time instructions for query statements of the database request component and make the query statements function with a deployed procedural logic component. The system maintains an association between the procedural logic component and the database request component during deployment. The system copies an internal representation of the procedural logic component to the target system without regeneration. The system regenerates the database request component to recreate the query procedure on the target system and to maintain a consistent interface between the procedural logic component and database request component.

Abstract: Techniques are provided for supporting versions of a routine. A first version of the routine is created. A second version of the routine is generated in response to receiving an alter statement including an add version clause. The second version of the routine is activated in response to receiving an alter statement including an activate version clause.

Abstract: A method and system for managing a computer system are described. The method and system include defining and storing a policy using a policy manager. In one aspect, the policy manager also activates and resolves conflicts between policies. The policy is a declarative statement of a directive to be carried out by the computer system. The method and system also include using a policy executor to determine whether a request to the computer system is covered by the policy. The method and system further include utilizing the computer system to carry out the directive for the policy if the request is covered by the policy through a policy enforcer.

Abstract: A method, computer program product, and system for processing dynamic statements in a database system are provided. The method, computer program product, and system provide for calculating a first set of characteristics associated with a dynamic statement when the dynamic statement matches one of a plurality of dynamic statements previously processed by the system, comparing the first set of characteristics associated with the dynamic statement to a second set of characteristics associated with one of one or more access paths generated for the one previously processed dynamic statement, and utilizing the one access path to execute the dynamic statement when the comparison of the first set of characteristics to the second set of characteristics satisfies one or more predetermined criteria.

Abstract: A method and system for using a procedure residing and executed entirely within a database system is disclosed. The procedure utilizes at least one variable, which has a plurality of attributes. The method and system include defining the at least one variable as at least one global variable prior to calling of the procedure. Defining the global variable(s) includes informing the database system of the plurality of attributes of the variable(s) and allowing the database system access to the at least one variable. The method and system also include tracking the global variable(s).
