合并 SQL 个数据库，保留一个索引
Merge SQL databases keeping one index
我必须为 POS 系统恢复 SQL 2008 R2 数据库，该系统在没有适当备份的情况下发生故障。 .BAK 文件已恢复，但已损坏。但是，我能够检索大部分数据并将其恢复到可用状态。
我现在的问题如下：
我有数据库 A，它是 POS 系统的全新安装，还有数据库 B，它是恢复的 .BAK 文件。
B 中的大多数表都缺少它们的索引值，而 A 具有完整的结构，但（显然）缺少所有有价值的数据。
我将如何合并两者，以便获得具有正确结构的完全索引数据库？
一种简单的方法是使用内置命令行工具tablediff.exe。它可以比较两个 tables/views，并打印出差异。
The tablediff utility is used to compare the data in two tables for non-convergence, and is particularly useful for troubleshooting non-convergence in a replication topology. This utility can be used from the command prompt or in a batch file to perform the following tasks:
- A row by row comparison between a source table in an instance of Microsoft SQL Server acting as a replication Publisher and the destination table at one or more instances of SQL Server acting as replication Subscribers.
- Perform a fast comparison by only comparing row counts and schema.
- Perform column-level comparisons.
- Generate a Transact-SQL script to fix discrepancies at the destination server to bring the source and destination tables into convergence.
- Log results to an output file or into a table in the destination database.
