是否有用于编写MSSQL表数据脚本的免费工具？我很乐意写一个，但我希望它已经完成，应用程序成熟之前/
答案 0 :(得分：18)
以下是我为反向工程SQL服务器模式编写的一些脚本。它们可能有一些用途。此外，作为一般兴趣，他们给出了一些如何从数据字典中获取各种信息的例子。我在下面添加了一个MIT许可证，以明确使用许可和一些基本的非隐式保修CYA。享受。

-- Script to generate table, index, pk, view and fk definitions from
-- a SQL Server 2005 database. Adapted from one I originally wrote
-- for SQL Server 2000. It's not comprehensive (doesn't extract
-- partition schemes) but it does do defaults and computed columns
--
-- Run the script with 'results to text' and cut/paste the output into
-- the editor window. Set the schema as described below.

Microsoft SQL Server数据库发布向导是一个很好的GUI，可以编写SQL Server 2000/2005数据库的结构/数据/过程的脚本。
希望这有帮助
答案 2 :(得分：2)
一个快速的谷歌和跳跃指向我应该能够帮助你的存储过程。请更详细地查看My code library文件generate_inserts.txt，看看它是否对您有帮助。
不是真正的工具，而是一个工具的开头！ ：）
答案 3 :(得分：1)
对于加载和卸载表格数据，您还可以使用bcp，Integration Services或BULK INSERT（对于加载部分）。 This article描述了一种从存储过程中调用bcp的方法。

TOAD for Oracle可以做到，所以我怀疑TOAD for SQL Server也能做到。
