![]() ![]() I no longer have the SQL scripts I developed, but what follows is the general strategy. The only items of interest were tables that had been added or dropped and columns that had been added, removed, or altered. I once had to compare two production databases and find any schema differences between them. I am including this answer for the sake of a new question that was marked as a duplicate. You can then either dump the results to a file and use a text file compare tool (even MS Word) or you can dump the results to tables and run SQL queries to find mismatches. Write a query (or queries) to get the information that matters to your code from the INFORMATION_SCHEMA views and run it on each SQL Server from SSMS. Also, the scripts contain a bunch of text that may be implementation dependent by default and may cause a lot of mismatch "noise" when what you probably really need to focus on is a missing table, view or column, or possibly a column data type or size mismatch. You can't really control the order in which generated scripts will present the objects in a database. Using the metadata in INFORMATION_SCHEMA is probably an easier option than generating DDL scripts and doing a source compare because you have much more control over how the data is presented. The easiest way is to use an automated tool built for this purpose, but if you don't have access to one, you can get all of the basic information that you need from the INFORMATION_SCHEMA views. Presto! Writing this up was significantly harder than doing the actual compare. You have to filter out hits from the date/time in comments, but otherwise it is a great comparison of the two databases. I then used Notepad++ to compare the SQL to a file generated in the same way against my SIT database. The wizard created one SQL which I copied via OneDrive back to my PC. I kept all the default options except the path/filename, but the tool has a plethora of options. ![]() to open a wizard to script the schema and configuration for the entire database (or selected objects if you want). So within SSMS, right click on the database to get the schema for. I have a production site with MS SQL Server Express and soon to be several more where I don't want to have to install VisualStudio or other applications other than SSMS. I had this exact same question and I believe that the Microsoft SQL Server Management Studio (SSMS) has a much easier/simpler solution than anything I saw here. You can have a look at this article or this one for sample code. ![]() Something like this: sqlpackage.exe /a:Extract /scs:Server=MyLaptopSQL2014 Database=Test /tf:C:UsersKevin3NFDocumentsSQLScriptsDACPACSTest.dacpacĪnd then sqlpackage.exe /a:Script /sf:C:UsersKevin3NFDocumentsSQLScriptsDACPACSTest.dacpac /tsn:MyLaptopSQL2014 /tdn:Test1 /op:C:UsersKevin3NFDocumentsSQLScriptsDACPACSDeltasTest1.sql /p:DropObjectsNotInSource=True /p:DropIndexesNotInSource=True sql file you can run to synchronize the databases. The result of the comparison could either be a xml report of the changes or a. You would extract your master database to a dacpac file and then compare the dacpac file to the rest of your databases. I don't have working code for you but you could look at the SQLPackage.exe documentation for some inspiration. If you need to compare more than one database file you could script SQLPackage.exe. Order by TABLE_NAME, ORDINAL_POSITION, COLUMN_NAME LEFT join ', into * from where Comment '-' IIF(oc.COLUMN_NAME IS NULL, convert(varchar(20), ''ADDED COLUMN''), convert(varchar(20), ''-'')) as Comment Select nc.TABLE_SCHEMA, nc.TABLE_NAME, nc.COLUMN_NAME, nc.ORDINAL_POSITION, nc.IS_NULLABLE, IIF(nc.IS_NULLABLE oc.IS_NULLABLE, ''Yes'', ''No''), Set the two variables newmodel and oldmodel to the appropriate database names and execute the scriptĭeclare table (TABLE_SCHEMA varchar(40), TABLE_NAME varchar(40), COLUMN_NAME varchar(50), ORDINAL_POSITION int, IS_NULLABLE varchar(5), NullChange varchar(5), Comment varchar(50)) After struggling with an easy way to do this same task - see what's changed between 2 models, I wrote the following SQL Script that will compare two schemas to determine new and deleted columns set nocount on ![]()
