How to visualize database tables in postgresql using pgAdmin? - sql

I am trying to visualize tables and their relations using pgAdmin. I have understood that there is a query visualizer tool available for pgAdmin. However, that only is useful if you are dealing with queries. My main goal is to generate a graphical representation of all the tables available in database.

In pgAdmin 4 right click on the database and then "Generate ERD (Beta)"

For pgadmin 3
Go to Tools -> Query Tool
Graphical Query Builder is a tab in the Query Tool view.
unfortunately Pgadmin 4 does not have this option.

I have found this webpage on postgresql wiki, with various tools on utilizing a postgresql database. I have used DbWrench on Mac to generate the ERD.

try pgModeler - there is working demo (although limited by number of objects). Also only PostgreSQL 9.x is supported.

You can use JetBrains DataGrip for visualize your database schemas. Create a connection to DB, and right click on [shema name] -> Diagrams -> Show visualisation.

Use Draw.io to generate SQL / DDL scripts?

There are a lot of resources on internet about how to import tables into ER diagram on Draw.io using sql script.
For example here (but I find plenty of resources googling):
https://desk.draw.io/support/solutions/articles/16000082007-use-the-sql-plugin-to-create-an-entity-relationship-diagram
(SEE PARAGRAPH "Create an ER diagram from SQL code")
I cannot find anything in the reversed direction. Is it possible to create DDL scripts from a ER diagram created through Draw.io?
(plugin? export as xml and import in other tools? anything else...)
I'm dealing with a ER diagram provided by suppliers in Draw.io format. I would like to avoid to handwrite all DDL...
(my case is Oracle 12)
I’ve got a PR in with a plugin that generates sql, DDL script from erdiagram see: https://github.com/jgraph/drawio/pull/3092. So yes it is now possible, if it gets merged in (or rewritten per their closed contribution guidelines) it will then be possible. You can also install the plugin manually (it’s one file).
Example Usage:
You can find the DLL options under arrange > insert
from sql or to sql buttons.
To SQL preview:
Reviewing this my old post I'd like to update that I did not find anything.
So the answer is NO. It's not possible to create DDL from design using Draw.IO
Suppliers were told to begin to learn and work free SQL Data Modeler inside Oracle Sql Developer. It's perfect because diagrams generated with this tool can be used to compare diagram generate from db, creating differences and incremental scripts.

Need tool for graphical projecting database which has option to generate CREATE scripts for different databases

Can someone suggests me tool for graphical projecting database which has option to generate CREATE scripts for different databases ?
Take a look at Oracle SQL Developer Data Modeler. (It is free, too.)

PostgreSQL visual interface similar to phpMyAdmin?

I'd like to view and possibly edit tables for PostgreSQL visually like phpMyAdmin, where you can see the list of tables, and fields and individual rows for a table. Is there any utility that can do this?
Forgive me if this is actually possible in pgAdmin III, but I couldn't figure out any way to see tables visually in pgAdmin. I have PostgreSQL 8.4 (I actually didn't install it myself, it was installed by another piece of software that utilizes it)
phpPgAdmin might work for you, if you're already familiar with phpMyAdmin.
Please note that development of phpPgAdmin has moved to github per this notice but the SourceForge link above is for historical / documentation purposes.
But really there are dozens of tools that can do this.
I would also highly recommend Adminer - http://www.adminer.org/
It is much faster than phpMyAdmin, does less funky iframe stuff, and supports both MySQL and PostgreSQL.
pgAdmin 4 is a powerful and popular web-based database management tool for PostgreSQL - http://www.pgadmin.org/
Azure Data Studio with Postgres addin is the tool of choice to manage postgres databases for me. Check it out.

ORM tool to create SQL tables

I need to create a database in SQLite, but I do not want to create the tables manually.
I already have the model of the data I need in the database, and what kind of relationship is each one (many-many, one-many, ...)
I'm wondering if there is a tool that allows me to do that?
I just need the tool to generate the SQL code. Then I will take care of the queries manually using SQL
I was thinking about placing the model in Django, and see what it generates, but there should be a tool not linked to a particular language that allows me to do that. Am I wrong?
Hibernate have the ability to create a scheme from mapped classes. There is support for SQLite.
You can go for dia (see "Tools that generates something from Dia diagrams" at http://projects.gnome.org/dia/links.html).
Also there is SQL::Translator and DBIx::* that allows reading an schema from YAML, Excel, and other sources, but these are Perl specific.
Good luck
You can use Symfony + Doctrine framework. It can generate SQL queries.
Try this module on CPAN: Parse::Dia::SQL

Utility to create an ERD from an already existing MySQL DB?

I have my database built already, but I really want to print out an erd to reference while I'm building my models. Is there a utility that can generate an erd from a SQL dump or by connecting to the database directly?
Thanks in advance,
~Brandon
The Data Modelling component of MySQL Workbench 5.2 OSS can do what you are describing, depending on the ERD notation you are seeking.
From the Home tab, select Create EER Model from Existing Database, then simply follow the wizard that displays. It will you run you through connecting to an RDBMS, choosing the objects to model, and then create the model for you.
If you're looking for traditional Chen or Crow's Foot notation, make sure you select Classic in the Model > Object Notation menu, and Crow's Foot in the Model > Relationship Notation menu.
MySQL Workbench
MySQL Workbench should be able to do this.
