是否存在创建sysdiagrams表并支持存储过程的存储过程？

Question

当前，我们的本地构建包括一个数据库构建&部署步骤，根据Sql Server 2008数据库项目中包含的数据库模型将数据库部署到开发人员的本地计算机。这适用于部署数据库模式，但无法部署任何已定义的数据库图。

为了部署这些图表，我们现在必须包括sysdiagrams表的CREATE脚本和设计器所依赖的存储过程，以及作为部署后部分的图定义的数据插入脚本阶段。

是否有更好的方式来部署sysdiagrams表和存储过程？这些是在sql server management studio中创建的，当在对话框中单击yes时，询问我是否想要创建用于图表的支持对象 - 这是否会调用我可以挂接的内容？我无法找到相关的存储过程。

Answer 1

有没有这样做的手段，你应该记住，SQL Server的版本之间的数据库图格式不同，因此SQL2008图不能直接插入到SQL 2000数据库中。该图存储为数据库中的二进制文件。

你可以继续做你现在正在做的事情或者在this link的工具上有一个lokk。

注：我没有连接到网站，所以不能担保，但它可能会给你一些想法。

有一个我用来导入和导出SQL图表的工具。 2008年的版本是Craig Dunn的Tool_ScriptDiagram2008。看看http://www.conceptdevelopment.net/Database/ScriptDiagram2008/。我使用它将图表导出为可以保存在源代码控制中的文本格式，然后可以使用源代码控制中的这些脚本在任何机器上重新创建图表。

Answer 3

没有这样的程序。如果你想保持你的图表安全的地方 - 脚本表sysdiagrams和支持对象，如果有数据并保留生成的脚本。就这样。

我较小的修改，可以创建sysdiagrams表（original source）的阱中使用存储的过程：

用法为所述DBO。 ScriptDiagram2008（@DiagramName）存储过程：

exec dbo.ScriptDiagram2008('My diagram') 

它会生成一个SQL脚本，您可以保存为图的“便携式”版本。执行该脚本将名为“我的图”的图插入到sysdiagrams表中。它甚至创建该sysdiagrams表，如果它不存在。
