Thisis commonly reported as an error due to using the wrong version of SSMS(Sql Server Management Studio). Use the version designed for your database version. You can use the command select @@version to check which version of sql server you are actually using. This version is reported in a way that is easier to interpret than that shown in the Help About in SSMS.

Just a heads up, Got the same message when I installed SQL Express 2022... Literally Installed SSMS (v18) by clicking the link after Express finished installing. I deleted V18 and downloaded V19, which is still in beta, and it fixed the problem.

I ran into this problem when SQL Server 2014 standard was installed on a server where SQL Server Express was also installed. I had opened SSMS from a desktop shortcut, not realizing right away that it was SSMS for SQL Server Express, not for 2014. SSMS for Express returned the error, but SQL Server 2014 did not.

I think the best method is to have the database generated as part of your build process. Keep all of the scripts in source control with the rest of the code, and everyone is responsible for their own environments.

Failing that, RedGate has a tool to integrate source control into SSMS and SQL Compare is useful for comparing/synchronizing MS SQL Server schemas. Visual Studio Database Edition also has a built-in schema compare tool.

Another SO question lead me to Migrator Dot Net which I am going to begin investigating during my copious free time. It looks like a good method, but it might be more of a time/overhead investment than you are willing to make.

eiefai already mentioned A table that should exist in all projects with a database. This is a great blog post, but IMO it only goes part of the way to a working solution for database revision control. I think any attempt to "answer" this question in the real world needs to consider some of the other information about VCS and databases:

There are a couple different angles to approach this question, I think. The "tool-first" angle, I believe, is going to vary based on platform and personal preference. Case in point: I'm using a Database Project in MS Visual Studio, but I'm not sure that this is a great solution for MySQL. I also know people who are pretty sold on their favorite tools from Redgate, Erwin, Embarcadero, etc.

There's also a "process-first" angle for this question, which will (hopefully) be revisited on this site in subsequent questions. The keystones in this process are getting your schema under source control and managing changes such that you can apply schema changes from version "x" to version "y" pretty much on demand.

A definitive answer to this topic is going to end up looking like a book, so it's probably worth starting out by referencing one: Redgate recently published a free ebook called "The Red Gate Guide to SQL Server Team-based Development", and while there's plenty in there to be debated, it's a pretty good place to start debating, IMO. Contrary to the name, much of the material in this book is general enough to apply to any DB (not just SQL Server) and any tool set (not just Redgate). If you haven't seen this already, it's definitely worth a skim, at least.

SchemaCrawler is my tool to produce a text file with all of database schema objects. I designed this text output to be both human-readable, as well as diff-able against similar output from another server.

In practice, what I have found is that outputting a text file of the database schema is useful, when done as part of the build. This way, you can check the text file into your source code control system, and have a version history of how your schema has evolved over time. SchemaCrawler is designed to automate this too, from the command-line.

Microsoft SQL Server 2014 Express edition has a database size limit to 10GB. Now, is that just for a single instance or the overall size that the edition will allow? Or does that means that I can have as many databases using the edition provided each database is less than 10GB?

This latter reference makes it clearer that the 10GB limit per database is applied to relational data, so it excludes log files* as well as FILESTREAM and FileTable data (both supported in Express Edition).

Relational Database Design and Implementation: Clearly Explained, Fourth Edition, provides the conceptual and practical information necessary to develop a database design and management scheme that ensures data accuracy and user satisfaction while optimizing performance.

Database systems underlie the large majority of business information systems. Most of those in use today are based on the relational data model, a way of representing data and data relationships using only two-dimensional tables. This book covers relational database theory as well as providing a solid introduction to SQL, the international standard for the relational database data manipulation language.

The book begins by reviewing basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL. Topics such as the relational data model, normalization, data entities, and Codd's Rules (and why they are important) are covered clearly and concisely. In addition, the book looks at the impact of big data on relational databases and the option of using NoSQL databases for that purpose.

MySQL Workbench is a unified visual tool for database architects, developers, and DBAs. MySQL Workbench provides data modeling, SQL development, and comprehensive administration tools for server configuration, user administration, backup, and much more. MySQL Workbench is available on Windows, Linux and Mac OS X.

MySQL Workbench enables a DBA, developer, or data architect to visually design, model, generate, and manage databases. It includes everything a data modeler needs for creating complex ER models, forward and reverse engineering, and also delivers key features for performing difficult change management and documentation tasks that normally require much time and effort.

Database Modeling and Design, Fourth Edition, the extensively revised edition of the classic logical database design reference, explains how you can model and design your database application in consideration of new technology or new business needs. It is an ideal text for a stand-alone data management course focused on logical database design, or a supplement to an introductory text for introductory database management.

This book features clear explanations, lots of terrific examples and an illustrative case, and practical advice, with design rules that are applicable to any SQL-based system. The common examples are based on real-life experiences and have been thoroughly class-tested. The text takes a detailed look at the Unified Modeling Language (UML-2) as well as the entity-relationship (ER) approach for data requirements specification and conceptual modeling - complemented with examples for both approaches. It also discusses the use of data modeling concepts in logical database design; the transformation of the conceptual model to the relational model and to SQL syntax; the fundamentals of database normalization through the fifth normal form; and the major issues in business intelligence such as data warehousing, OLAP for decision support systems, and data mining. There are examples for how to use the most popular CASE tools to handle complex data modeling problems, along with exercises that test understanding of all material, plus solutions for many exercises. Lecture notes and a solutions manual are also available.

This edition will appeal to professional data modelers and database design professionals, including database application designers, and database administrators (DBAs); new/novice data management professionals, such as those working on object oriented database design; and students in second courses in database focusing on design.
