问题 RedGate makes a tool for Microsoft SQL Server that allows you to snapshot the difference between two databases. It generates the scripts needed to update the database schema while preserving the data. I need to find a tool like this for the Firebird database. We use Firebird in an embedded fashion, and would like to push out schema updates to remote machines with as little hassle as possible. 回答1: I don't know of a tool for Firebird that does exactly the same. However, FlameRobin allows you

   本文主要把一个菜鸟从“只是听说过Spring MVC”到“可以手动创建并运行一个Spring MVC工程”的过程记录下来,供以后复习。 0. 开发环境准备   计算机平台:Windows 7 X64。   需要准备的软件和相关库包括: JDK8 (jdk-8u74-windows-x64)、 Eclipse (eclipse-jee-mars-2-win32-x86_64)、 Tomcat (apache-tomcat-7.0.68-windows-x64)、 Spring (spring-framework-4.2.5.RELEASE-dist)、 Logging (commons-logging-1.2-bin)、 Jstl (jakarta-taglibs-standard-1.1.2)。 1. 软件安装    JDK8   安装到系统。安装完成后添加系统环境变量: JAVA_HOME (D:\Program Files\Java\jdk1.8.0_74)、 CLASS_PATH (.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar)。如果在cmd中运行“java -version”提示找不到java命令,那么就在 PATH 环境变量中增加:%JAVA_HOME%\bin;    Tomcat

问题 In Sql Server 2008, when I create a table without schema prefix: create table mytable ( id int identify ) it usually ends up in the schema dbo, with name dbo.mytable. However, on one of our servers, the tabel ends up belonging to me: andomar.mytable Which configuration difference could explain this? 回答1: It depends what your default schema is within that database. Even in SQL Server 2005, if your default schema in that one database is andomar, then any tables created without an explicit

understand YANG and its goals

问题 I've read https://en.wikipedia.org/wiki/YANG but still having problems to understand the practical use of YANG , and the benefits it provides. As I understand, it now is used not only by NETCONF, as was originally designed. YANG is not a language in a common sense, as C or python for instance, i.e. whatever we write in YANG is not compiled or translated; as I understand is is used as a reference model for a higher level library or application. Then the question is how does the high level code

Flattening XSD schema documents (HR-XML 3.0) [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I have several "main" XSD documents, which import "supporting" XSD documents. These schema documents happen to be from the HR-XML 3.0 specification, in particular related to Background Screening. For the purposes of code-generation and convenient single-file schema to reference in my WSDL, I am trying to "flatten"
