1. The match function wakes up the string with the specified regular expression function and returns the matching string prototype as an array: Stringobj.match (REGEXP) Parameter: Stringobj required option, need to go to match string regExp required option, The specified regular expression return value: If the G (Global match) option is not used, the first matched string, the location of the string, and an array of the original string are returned, and if the G option is used, an array of all ma

Recursive queries in SQL statements SqlServer2005 and Oracle two versions Before using Oracle, think of its recursive query is very useful, the study of SQL Server, found that it also supports recursive query in SQLTo illustrate:The SqlServer2005 version of SQL is as follows:For example, a table with ID and PID fields, ID is the primary key, PID represents its ancestor node, table structure and data:CREATE TABLE [AAA] ([ID] [int] NULL,[PI

cannot change its data locally. At the same time,Git builds a local master branch of your own , which points to a copy you've just uploaded from remote to your local server. As you continue to change files,git add, git commit,Master 's point will automatically move, you can also move through the merge(Fast forward) the point of Master. $git branch-a (to show all the branches git knows about)* MasterRemotes/origin/head-Origin/masterRemotes/origin/master$git branch-r (to show remote branches g

git clone command parameters:Usage:git clone [Options] [--] There are many parameters, but there are several common ones:1. The simplest and most straightforward commandgit clone xxx.git2. If you want to clone to the specified directorygit clone xxx.git "Specify directory"3. Clone creates a new branch instead of the default Origin HEAD (master)Git clone-b [new_branch_name] Xxx.git4. Clone Remote BranchThe git clone command defaults to only the master branch, and if you want to clone a remote br
