Storing the database diagram’s data into a text by writing some T-SQL scripts The first question here is how do we get the data out of the table? OR how do we export the database diagrams? There are two approaches here: But, the database diagrams are stored in a varbinary column in a table. We know where the database diagrams are stored now. In sysdiagrams, “diagram_id” is an identity primary key so it will be generated automatically. As it is obvious it is a system table and you can find it in “System Tables” folder in SQL Server Management Studio’s object explorer. The structure of the diagram is stored in the “definition” column using varbinary data type. The sysdiagrams contains a column named “definition”. Where the database diagrams are stored?Īctually the diagrams are stored in a table called “sysdiagrams”. Now you are able to create your diagrams. To do so just right click on the database diagrams in object explorer in SQL Server Management Studio and select “Install Diagram Support”.

First of all you should install diagram support in your database. Here is a work around that might help you. The following solution could be great for sharing the database diagrams in the development team as well by sending them the diagram file by email and/or storing the database diagram file in a network shared folder. So I decided to store the database diagrams in a file system basis that I can reuse it again and again. I didn’t like to create the whole database diagrams that I’ve created before in a database that a new version of it is newly released for testing as it is a kind of rework and it is a time consuming process. I’ve faced to this feeling specially when I was testing some databases which were under development. Sometimes you might feel you need to store the database diagrams in a file basis.
