How to compare database structures?

[Evgeny Gopengauz]

Let us suppose that I have two similar databases and need to create an
sql-script upgrating one database structure to another. For example, these
databases are from different versions of some software, first is from early
version, next is from current, and second one contains several new tables,
sevelal new fields in old tables, several new or changed stored procedures,
UDFs and so on.

How to solve this problem using standard tools?

With the tools supplied with MSSQL, there's really no way to do this
easily. Most people buy a third-party tool (Red Gate, Embarcadero
etc.) to do comparisons and migrations. There are some good, cheap
tools, and unless you have lots of time and you want to re-invent the
wheel, you should probably investigate what's available.

Thank you! Now I guess why I have found nothing in the BOL :)

The latest issue of SQL Magazine has a tool from www.apexsql.com that may
help you out.

In a pinch, you can always dump the structures of the two databases into
two text files and use a DIFF utility to identify the differences. No
very sexy but it gets the job done.

Hi Evgeny,



Try dbMaestro. It's a product that allows comparison, migration and
archiving of database schema and data. it is generate migration script
for different between schema and data , and you can run this script on
sql server

You can find it here:
