i have installed a PostgreSQL database.Now i need to download and import a food mart database to practice some reporting techniques.I am new to this field so do not know where to start.Please it will be very helpful if anyone can provide me a guidance to start it.
This repo contains the foodmart data loader for Postgres, Mysql, Sqlserver, Sybase
https://github.com/OSBI/foodmart-data
All you need to do is clone it and launch the following script:
sh FoodMartLoader.sh --db postgres
connection props are set inside the script
For Clickhouse DB2 and SAP Hana and some other DBs look at the branches of this
fork:
https://github.com/contiamo/foodmart-data-public

is there a way to create a dump of your database with the models, so that I can just push it on another database and just have to update my database address and all works out fine?
Exporting from Prisma CLI itself is not possible as of now.
But what you can do is dump the db from the postgres cli.
And then Import the dump in your new DB : Guide from Prisma
Connect to this DB in your new application add a schema.prisma with base configuration, without models and pull the DB: Introspection Guide from Prisma
I would be happy to get your help / feedback re data load.
Goal:
Load source data from a Postgres database, which is located in GCP project A to another Postgres database, which is located in GCP project B.
Challenge:
Get a connection (I have an IAM account with sufficient rights to run a COPY TO / COPY FROM command) to the Postgres DB in GCP Project A and copy the table either to a CSV or create a dump that can be used in order to be inserted to another Postgres DB in GCP Project B.
How do I connect to the database (e.g. if I create a key, where shall I store the json keyfile and would that approach even be feasible?) with this IAM email account?
Other ways I've researched were to use psycopg2 (thus I could use the function cursor.copy_expert (which doesn’t need any superuser right or Postgres user credentials and copy the data), but I didn’t succeed in connecting to the database with psycopg2 due to challenges with cloud proxy.
Another idea was to use pg_dump or gcloud sql export csv.
I would be curious if some of you were facing a similar challenge and how did you solve it and what might be the best way/practice
You can have a try out database migration service. You can set up a continuous migration configuration and use Cloud SQL for PostgreSQL.
Hello after a lot of searching I've come to these solutions:
If you have continuous copy, you need to use the database migration service, check this documentation.
If you have one shot copy:
you can restore your instance, see the bottom page of this documentation
you can create a bucket and backup your instance on it, then import it from the other project
I have deployed my SpringBoot app to Heroku. Now I would like to copy my local PostgreSQL to Heroku.
I have found some information on devcenter.heroku.com.
However I don't understand enough about the using of file db.changelog-master.yaml.
Could anyone give me details about the simplest solutions to copy the database?
Create a valid dump of your local postgres database and host it somewhere publicly available. Now you will be able to restore this entire dataset (schema and records) with pg:backups:restore as shown here. The sole caveat here is that the target database must be completely empty for this to work. You can empty a Heroku postgres database with heroku pg:reset.
If you cannot take the approach listed above then you can run pg_restore directly from your local instance, provided your local version of Postgres is >= the target version of Postgres. This also applies to creating the dumpfile and is a requirement because pg utilities are not guaranteed to be forward compatible. Documentation for pg_restore is here.
I've downloaded a backup of a Mongo database from a production application I have hosted on Mlab.com
I want to import that database to my local meteor application so I can test some changes to the architecture of the collections on the real application data without breaking the production app.
Is there a way to do this?
Much appreciated
You will need to install Mongo locally on your machine to get the utilities you need, which is basically mongorestore. The command will look something like this:
sudo mongorestore --db newdb --drop /var/backups/mongobackups/01-20-16/newdb/
Meteor can connect to your database using this environment variable:
MONGO_URL=mongo://localhost:27017/newdb
There is an article about it for more detail here: https://www.digitalocean.com/community/tutorials/how-to-back-up-restore-and-migrate-a-mongodb-database-on-ubuntu-14-04
I have got a sql file where is configured a database in PostgreSQL technology. I created a database from sql file but from code it is hard to understand action/connecting between the tables. Is it some tool which show all the connections between tables for PostgreSQL?
