Toad for Oracle offers many different editions, the higher the edition, the more features and capabilities. To solve this situation, we have a perfect solution available from Toad for Oracle, which is the Compare Schemas tool. Of course, today, when working on large projects, complexity has greatly increased as there can be so many different and interrelated object types that it is no longer possible to simply use simple, self-made scripts. Several years ago, when I started in Oracle technologies, my first contact was in Database Administration and in those days I remember that as I was getting started in that new world, I typically would just manage few objects from the Oracle database-such as tables, indexes, synonyms, views-and could generate simple scripts to be able to determine the differences in both environments without much difficulty.
#Compare databases using dbschema how to#
Make sure to read my second blog in this series, How to compare multiple database schemas in Oracle using Toad. I will guide you step by step on how we can compare two Oracle database schemas using Toad® by Quest® for Oracle. If you find yourself in any of the above situations, this article is for you. Needing (as a DBA to be able to guarantee that the production environment has not changed and/or want to know how the development environment differs from the production environment.Wanting (as a developer) to build a lab for research and study.Wanting to duplicate an environment to work with some specific requirement.In the need to replicate our development environment for testing and implementation without impacting the main development environment.Suppose we are developing a web application using the Oracle database as our data storage and we find ourselves: Graham GoodwinAre you a developer? Learn to compare two Oracle database schemas using Quest® Toad® for Oracle.
This may just involve a little more work though than simply comparing against a dbschema file. sln files would be to deploy one of them to a local database file and then perform the schema compare between the other project and this database. I suppose one other way to perform a comparison between 2 branched. Is this correct? Is this process of creating a branch for each release version of the database the recommended way of going about maintaining different versions of a database? If so, to me it would be extremely beneficial if the 'Schema Compare' option in GDR allowed you to select a project from a different. With your suggestion of checking the corresponding dbschemas into each solution, this would then involve us 'getting' the relevant dbschema (say to local disk) from a specific branch solution and then performing a compare from another branch solution project against this dbschema. Hi Barclay You are correct when you say that we have the same solution (in our case 'FinanceReporting10.sln') in different branches but at various stages of development. Please mark the responses as the answer if it resolves your question/issue. Visual Studio Data Tools (DataDude, DBPro, Database Edition, Database Projects, VS Data Tools) If the database project is simple enough and does not have many 3 or 4 part refs then you can automate easily with the vsdbcmd 2010 version which allows you to compare 2 dbschemas from the command line. Check out this recent blog post on this: A schema comparison between branches is something that you tend to do often if you have more than 2 concurrent versions. You can also create additional solution files to help compare specific projects/solutions.īest guidance here though is that you will want to automate it. If you have alot going on in pre and post deployment scripts then you really need to be deploying to the sandbox databases to do the comparison. It can also depend on how complex your project is. You do typically want to branch for each released version of the application/database if you plan to service/patch it.Īnthony has some good points and suggestions above. You do this when the costs of pulling source for a specific branch/version and building it out weighs the cost of archiving the. This gives ready access to always the latest and greatest, but also the last know from a specific branch. Some customers automate the archival of the dbschema into source control from the build machine.
