As shown in the following:In this picture, the reader can see that there is a sky in the scene, and no matter how the game character moves in the scene, it cannot be close to the sky. By adding such effects, the game world is more colorful and closer to the real

About with cube, with rollup and grouping View the help document of SQL 2005 to find the specific difference between cube and rollup.: The result set generated by cube displays the aggregation of all the combinations of the values in the selected column.

About the WITH cube, with rollup and grouping The specific differences between cube and ROLLUP are found by looking at the Help documentation for SQL 2005 : Cube produces a result set that shows aggregates for all combinations of values in the selected column. The result set generated by ROLLUP shows the aggregation of a hierarchy of values in the selected colu

In Oracle SQL queries, Oracle provides advanced features that simplify SQL query statements and improve query performance. The usage and differences of Rollup,cube are described below. 1. RollupRollup can calculate subtotals and totals for multiple levels of a specified grouping field in a SELECT statement. The rollup is very easy to use and very efficient.Rollup scans the grouped fields from right to left, gradually creating a higher-level subtotal.

During the project, we often encounter issues that are summarized by departments and personnel. It is quite convenient to handle such problems in Oracle! The following describes the instances encountered in the project: The query statement is as follows: Select f_sys_getsectnamebysectid (A. sectionid) as sectname,-- A. sectionid,F_sys_employinfo_getnamebyno (A. buyerid) as name,Sum (C. ratio) as llratio,Sum (B. ratio) as lratio,Sum (A. ratio) as ratio,Sum (D. ratio) as nratioFrom (select sect

Special adjacency table-cube adjacency table: Considerations for some special cases of linked tablesWhen we are learning graphs, we all know that the commonly used methods of saving graphs have adjacency matrices and adjacency tables. When the number of edges in the graph is less than the number of vertices, there are many 0 values in the adjacency matrix, that is, the sparse matrix is formed. This time using the Adjacency table to store the diagram c

Because ice is a kind of transparent special matter, not only the light through the refraction phenomenon, and the edge of the ice will produce a frost-like phenomenon, so many people think that the use of Photoshop to achieve Ice cube effect will be difficult. In fact, using Photoshop7.0 can easily achieve this effect. Here is a step-by-step guide to learn to use PS to make Ice Cube effect. Figure 1 1. Op
