Dbschema schema compare update#

This software not only compares the schema, but also provides the options to update or drop them as per the choice. In this example, we can see that AdventureWorks2012 database has an additional index.ДЇollowing example is very interesting as in this case, we have changed the definition of the stored procedure and the result pan contains the same.ДbForget Schema Compare very effectively identify the changes in schema and lists them neatly to developers. In very first option we can see that there is an additional column in another database which did not exist earlier.

Let us click each of them one by one to see what is the difference between them. Two of the changes belongs to the tables and one changes belong to the procedure. As mentioned above there are three different changes in the database and the same has been listed over here. Once you click on compare in previous screen it will bring you to this screen, which will essentially display the comparativeВ difference between two of the databases which we had selected in earlier screen. The screen lets you select the objects from SQL Server 2000 to SQL Server 2012. You can see the options which are available to select. This is the most important screen as on this screen we select which kind of object we want to compare. We will not change anything in schema mapping screen as in our case it is not required, but generically if you are comparing across schema you may need this. In the next screen we can verify various options but for this demonstration we will keep it as it is. I have selected AdventureWorks2012 and AdventureWorks-V1 databases. It will bring you to following screen where we have to configure the database needed to configure. Now let see how dbForgeВ Schema Compare works in this scenario.ДЇirst open dbForgeВ Schema CompareВ studio.

One of the tables has additional column.

There are total three changes between these databases. First, I have two different databases вЂ“ a) AdventureWorks2012 and b) AdventureWorks2012-V1. I personally use Devart Schema Compare for this task. As discussed earlier, it is absolutely impossible to do this task without the help of third party tools. Before deploying any changes to theВ production server, I personally like to make note of the every single schema change and document it so in case of any issue, I can always go back and refer my documentation. If you are developer or database administrator who works in the production environment than you know that there are so many different occasions when we have to compare schema of the database. Table Schema has been just one of the concept, but if you really want the all the schema of the database (triggers, views, stored procedure and everything else) it is just impossible task.

If you think about comparing the schema manually, it is almost impossible to do so. From the blog post I have received quite a many question that just like data how we can also compare the schema and synchronize it. Earlier I wrote about An Efficiency Tool to Compare and Synchronize SQL Server DatabasesВ and it was very much well received.
