Import .db file to postgresql using terminal - postgresql

I am on ubuntu, i have Postgresql 13 installed on it. I have a file named (order.db) which is actually a database with a few tables in it. I want to import whole of (order.db) into postgres with same database name and of course the data. Is there any way to do it using terminal? any command?
The order.db file was created with the help of sqlite3 collaborating with c++. Order.db had nothing to do with postgresql at earlier phases of my project. I just want this (order.db) file to be imported as a database to my postgres.

How to restore a PostgreSQL database from dump file in dbeaver?

In our company we have a dump of PostgreSQL database - file db.sql. It weighs 8 Gigabyte. How to restore this database in DBeaver? And we don't have another databases in DBeaver 7.0.5.
I have digged all Internet and haven't found anything how to do this without another database/
When you right click on the database you want to restore into, under "Tools" you will find "execute script". This is how you restore a plain-format dump file, which is what db.sql probably is.
This will require you to have psql, but dbeaver will offer to download and install its own copy of it for you.
Create a new DB and right click on the db, click on tools and restore. Choose your dump and import it.

Using QGIS project saved in Postgres as project file for QGIS server

I am trying to set up a Qgis server on debian that uses a Qgis project file stored in a Postgres db.
To get started I followed the official Qgis Training Module Lesson 12.1.
When using a project file stored locally on the server, it works fine.
Now I tried to change the "default qgis project" in the qgis.demo.conf file and indicate my project file stored in the postgres database according to this template : postgresql://localhost:5432?sslmode=disable&dbname=mydb&schema=myschema&project=myproject which I found in the QGIS User Guide.
My edited line in the qgis.demo.conf looks like this:
SetEnv QGIS_PROJECT_FILE postgresql://localhost:5432?sslmode=disable&dbname=Test&schema=public&project=world
When doing a GetCapabilities request I now get:
"WMS configuration error" There was an error reading the project file or the SLD configuration.
I looked in the qgis.server.log to understand what is going wrong.
"Error, configuration file 'postgresql://localhost:5432?(...)' does not exist"
I am able to access the stored project file with qgis and with pgadmin 4 I can see that it is stored in the database.
Do I indicate the project file wrong?
you should complete the connectionstring with user and password
SetEnv QGIS_PROJECT_FILE postgresql://user:password#localhost:5432?sslmode=disable&dbname=Test&schema=public&project=world

How to create db file with SQLiteStudio

I have created the database for my Android app using SQLiteStudio 3.0.5 and now I need to save/export the one as .db file, but i found only the export to .sql-file. So, what should I do to make such procedure?
When you create database in SQLiteStudio it already is a proper sqlite database file. If you need to name it with .db extension, just rename the file in any file manager.
It sounds like you are trying to export the SQL command, and not the database itself.
Right-click on the database, and select "Export the database".

How to bundle current schema/tables into user environment(Windows)

I'm trying to bundle PostgreSQL into my Windows application.
I have downloaded a binary PostgreSQL and created lots of tables under the new schema.
I was wondering if I could just copy the current database into the directory user would select.
Question:
Do I have to run 'initdb' in my installer? If that is the case, I think the current schema/tables are removed so I should run the external sql file which includes all of table creation commands. Is that correct?
What is the simplest way for me to bundle my current schema/tables into the user environment through Windows installer steps.
Add:
I realized that I couldn't just copy the current database into other system as it depends on the OS user in Windows.
I will run 'initdb' in my Installer and also run a table creation script.

MySQL Workbench Rebuidling Database From Script File

I have a script file that has a bunch of create commands, and one that has a bunch of inserts. I would like to use these commands to rebuild my database on a different PC but I am struggling with how to accomplish this.
I just installed a fresh copy of MySQL Workbench and I created a new Model. Now what?!
Thanks for the help!
You should be able to rebuild your tables from the script
First, connect to the database
Then, open your script file
Run the query
After that, you should have your tables restored.
