we can give each volume or each directory to set different permissions, once a network security accident, can also reduce the loss to the minimum. Of course, you can also distribute the site's data on different servers, make it a server farm, each server has a different user name and password and provide a different service, so the security is higher. But people who are willing to do so have a feature----money:). Well, to get to the bottom of this, the server's database for Ms-sql,ms-sql serv

If there is only one return value for a method, it is only possible to define a method for each one, but with ref and out it is much easier to implement.RefCopy CodeThe code is as follows:static int Getintresult (int[] arry, ref float AVG, ref int max, ref int min){int sum = 0;max = arry[0];min = arry[0];for (int i = 0; i {Sum + = Arry[i];if (Max {max = Arry[i]

page/sec. In order to parse the reference to memory, the number of times page files must be read. The threshold value is greater than 5. The lower the threshold, the better. A large value indicates disk read rather than cache read. Because too many page swapping requires a lot of hard disk space, it may lead to confusion between insufficient Page Swap memory and the disk bottle diameter that leads to Page Swap. Therefore, you must track the following disk usage counters and memory counters when

One, group function nestingAs defined in Oracle, group functions can be nested only two layers. In fact, multi-layer nesting has no practical purpose, so Oracle does not provide multi-layered nesting of group functions. However, a single-line function can be nested multiple layers.Two1. Oracle contains the following group functions-avg ([distinct| All]n) return average, ignoring null values-count ({*|[ Distinct| ALL]}EXPR) returns the number of record

be divided into single-row functions and multi-row functions. Oracle functions return values. The single-row function works for each row in the query result and returns a result. A multiline function, also called a grouping function, returns a result for a group of query records or multiple rows. Single Row: operation data item. It accepts parameters and returns processing results. It takes effect for each returned row. The data type can be modified and can be nested. Single-row functions inclu

The data type can be modified and can be nested.Single-row functions include character functions, numeric functions, date functions, conversion functions, and general functions.Multiple rows: Also known as grouping functions, that is, operations on a group of data. Only one result can be returned for a group of data (multiple rows of records ).Multiline functions include AVG (), count (), max (), min (), sum (), etc.For example, select
