正则表达式中方括号和括号之间有什么区别?(What is the difference between square brackets and parentheses in a regex?)

这是一个我在JavaScript中使用的正则表达式:

var reg_num = /^(7|8|9)\d{9}$/

这是我的团队成员建议的另一个。

var reg_num = /^[7|8|9][\d]{9}$/

规则是验证电话号码:

  • 它应该只有十个数字。
  • 第一个数字应该是7,8或9中的任何一个。

Here is a regular expression I created to use in JavaScript:

var reg_num = /^(7|8|9)\d{9}$/

Here is another one suggested by my team member.

var reg_num = /^[7|8|9][\d]{9}$/

The rule is to validate a phone number:

  • It should be of only ten numbers.
  • The first number is supposed to be any of 7, 8 or 9.

最满意答案

C:\Program Files\Microsoft SQL Server\100\SDK\Assemblies是64位系统上正确的文件夹位置(或C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies )。

您需要添加引用:

  • Microsoft.SqlServer.ConnectionInfo.dll

  • Microsoft.SqlServer.Smo.dll

  • Microsoft.SqlServer.Management.Sdk.Sfc.dll

  • Microsoft.SqlServer.SqlEnum.dll

(这些是构建SMO应用程序所需的最小文件)

对于SQL Server 2016,此位置为C:\Program Files (x86)\Microsoft SQL Server\130\SDK\Assemblies (对于64位版本)。

参考: 如何:在Visual Studio .NET中创建Visual C#SMO项目

SQL Server管理对象(SMO)可作为相关SQL Server(20XX)功能包的一部分下载(检查小印,因为我不认为这些可重新分发?)


C:\Program Files\Microsoft SQL Server\100\SDK\Assemblies is the correct folder location (or C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies on 64-bit systems).

You need to add references to:

  • Microsoft.SqlServer.ConnectionInfo.dll

  • Microsoft.SqlServer.Smo.dll

  • Microsoft.SqlServer.Management.Sdk.Sfc.dll

  • Microsoft.SqlServer.SqlEnum.dll

(These are the minimum files that are required to build an SMO application)

For SQL Server 2016, this location is C:\Program Files (x86)\Microsoft SQL Server\130\SDK\Assemblies (for the 64bit version).

Ref.: How to: Create a Visual C# SMO Project in Visual Studio .NET

The SQL Server Management Objects (SMO) are downloadable as part of the relevant SQL Server (20XX) Feature Pack (check the smallprint as I don't believe these are redistributable?)
