I would like to generate the ERD of an existing database in DBeaver.
To generate the diagram the procedure is to open the database > Schema > right click Public > View diagram.
Like it is shown in this video:
https://www.youtube.com/watch?v=ZGVXwCYkGJQ
The problem is that for me "Schema" is not shown.
Like you can see in the image below.
How can I display that?
Or if you have an alternative way to generate the ERD would help also.
Thanks.

I have a simple question. When you create a table/query from Pgadmin, how do you find the source code ( not sure if these are the correct words) you used?
I have looked under schema and can't find anything.
Attached is a photo. Thank you
Select the object on the left tree view and go to the SQL tab on the right to see the DDL.
We have a MySQL Workbench project with two tabs (two schemas/two databases).
If we create a table in the first tab, it's attached to the schema
magikweb_dev_igcweb.
If we create a table in the second tab, it's attached to the schema
magikweb_dev_igcweb_archive.
If we copy-paste/duplicate a table from the first tab to the second tab, the resulting table remains in the first schema. How can you change a table's schema?
Each schema is linked with a specific database, so when we use the "Synchronize Model..." feature, it links all the tables properly.
Use the model tab. You can cut out a table from one schema tab and insert it into another.
The cut-and-paste method described in another answer works well for tables with no foreign keys, and for a reasonable number of tables.
An alternative that preserves foreign keys is to export the model as a SQL script, edit it, and then import the new script into a new model.
Using MySQL Workbench v6.3:
File -> Export -> Forward Engineer SQL Script
Carefully edit SQL script. Replace references to one schema with the other, for the tables you want to move. Do this both for CREATE TABLE commands and foreign key references.
File -> New Model
File -> Import -> Reverse Engineer SQL Script
Unfortunately you will then need to recreate any diagrams. But that can be straightforward if you have the original diagram as reference (take a screenshot or export it to PNG or PDF.)
Follow this simple steps (never miss step 4 and 5) :
Open Model Tab
Choose source schema. In my case, I want to copy table users from schema abc_develop_v1 to schema abc_develop_v2 then paste to diagram . So I choose schema abc_develop_v1, right-click table users then Copy 'users'
Go to the targeted schema. In my case is schema abc_develop_v2, right-click then Paste 'users'
Next, copy table users from schema abc_develop_v2. Right-click table users then Copy 'users'
Go to your diagram and Paste 'users'.
That's all. Your table is ready in your diagram with the right schema :-)
Notes: You can double check by double-click on the table in your diagram, and look at the right corner. It will show the Schema name.
I found a less painful way to do this.
Save and backup your diagram and your schema.
Display schema's name before table's names in diagram. This will make the next step easier.
Right-click on the tables which are on the wrong schema, and select "Copy SQL to clipboard". Paste the script in a new SQL window. Repeat for each table you want to migrate.
Edit the script to change the schema name. Watch for any miss in entries, the wrong schema might be a reference at any line. Mine was mydb, which I don't remember creating. Execute the script. Now you have the tables on the right schema.
Synchronize your model. Be sure to check "Update the model" for each missing table, otherwise, the tables will be deleted from the schema :)
Drag'n'drop the newly created tables into the diagram. Then remove the ones which are using the wrong schema. Tip: tables that are not in diagram won't display a dot next to their name.
Optionally, you can delete the faulty schema from the model so this never happens again. Be sure to know what you're doing first!
I have a new table I want to add to an existing db, the structure of which I exported to a file table.sql.
table.sql has 75 columns, so naturally I would rather find a way to copy/import the structure into the existing db than creating a new table and manually defining each of the 75 fields.
Is there a way to import this table structure into my database mydb (which is populated with data)? There has to be -- this is computing. I am staring at phpmyadmin and can't figure out how to do this.
Any suggestions would be welcome.
Thanks in advance.
okay, figured out how to do it. I just opened the exported .sql file, and copied/pasted the "CREATE TABLE..." statement into the DB's SQL window in phpMyAdmin and it worked -- I now have that new 75-column table.
But I'm still a bit mystified over why phpmyadmin gave a success message when I tried to import the .sql file but did not display the allegedly imported table.
There is an Import tab in phpMyAdmin.
Open the database you would like to import into, then click on the "Import" tab and upload your file.
You can learn more here: http://www.techrepublic.com/blog/smb-technologist/import-and-export-databases-using-phpmyadmin/
An alternate way would be to copy the mySQL statement(s) in your table.sql file, open the "SQL" tab, paste it in the box, and then the run the query.
I hope this helps!
It's easy. You should choose your database then in the Import tab, select choose file. Select your file then press Go. It worked for me. You can find the new table in your database.
I want to generate ER - Diagram for existing database. I created .dbm file but in diagram I see only table names all in a row. I am not able to see columns and relationship between tables.
How can i see ER- diagram.
I got answer in data studio forum.
Columns can be displayed by changing the properties view. Click a blank area of the diagram and in the filtering tab of the properties and change the display options. To see relationship right click on blank space and click on show implicit relationships.
The table with blue header is normal mysql table, while the one with yellow header is view table. I used reversed engineering to import these tables into mysql workbench and trying to place relationship among them using existing columns, but I can't expand and see the columns of view table.
It is the limitation of mysql workbench, or actually it is possible to expand the view table? If it is able to expand, can someone please guide me on this?
Thanks!!
This is currently a limitatiion and, to my surprise, not something that people requested in the past. If you like you can open a feature request at http://bugs.mysql.com to get this implemented.
