 How to copy Database Structure from one db to another w/o affecting data Is there a way to copy the structure from one database to another without affecting the actual data? For example, I added new fields and stored procedures to a db in my development environment. There are a lot of them. I now want to make the same changes to my production environment db but don't want to affect the data. Only the fields, stored procs & constraints and stuff pertaining to the structure of the db should be changed. Does anyone know of a program that can do this or can this be done in MS SQL Enterprise Manager. Any help would be appreciated. 7078895      |

Alternatively, there are third-party tools available, such as this one: http://www.red-gate.com/SQL_Compare.htm However, the real answer is probably that you need source control for your SQL code, as well as a standard deployment method and/or tool. There are lots of discussions in this newsgroup (and others) about this - you can search for "source control" to find them. Simon |

In addition to Simon's post, I like to add that there is no tool in this whole wide world that can read your thoughts and do what you want. Sure, loading new stored procedures is piece of cake. But if you have addded, changed or drop columns, there needs to be a human to decide what is going to happen with the data. A tool can generate a boiler- plate for you, but you are setting your data at risk, if you run it without reviewing. And testing. (Take a backup of the production environment, and run the update script there until everything seems fine.) -- Erland Sommarskog, SQL Server MVP, esquel@sommarskog.se Books Online for SQL Server SP3 at http://www.microsoft.com/sql/techinf...2000/books.asp |
