This article describes an easy way to prevent users from submitting the same form multiple times during the current session in an ASP application. It is mainly composed of four sub-programs, in a relatively simple application, you just put the code in the included file directly reference, for those more complex environment, we at the end of the article to give some suggestions for improvement.First, the basic work processHere we discuss these four subroutines in turn.(i) initializationHere we ar

The supported data types are different, so I will not elaborate on them here. If you need them, Baidu ~ 1. Create the simplest table Suppose: we define a name T_Person table. The table has three fields:

16; 4 6 13 20 22; 10 12 19 21 3; 11 18 25 2-9]; >> FID = fopen (' B.txt ', ' W ');fprintf (FID, '%gn ', a); # N-line fclose (FID); Then use WordPad to open b.txt, which reads as follows: for column vectors 17 23 4 10 11 24 5 6 12 18 1 7 13 19 25 8 14 20 21 2 15 16 22 3-9 In the second case: Make changes to the above command: # N line change to t,table key >>

When you update a table in bulk, you need to rely on a different table when you update a column of a table, which can be a where conditional clause, or the value of the field that you want to update depends on another tableThere are usually two ways of doing1. Using Stored Procedures2. Loop through the program codeHere is a more efficient, concise approach, batch update SQL, a SQL can replace the troublesome loop process, with MS SQL Server, Oracle, DB2 under the wording--Key points: T4 and T1 a
