In this article I’ll show you how to use the Postgres Database Editor to create a database in Python and run it through a batch file.
I’ll also show you the basic functionality of the PostgreSQL database editor.
To start off, let’s get started.
In this tutorial, I’m going to show you a simple SQL query.
Let’s create a Postgres database in this simple example.
Open up your favorite editor and click on File -> New SQL Database…
Type in your Postgres project name.
Now, you should see something like this: PostgresDatabase.sql Now, type in the following code to create the database: # create a new database db = new PostgresSQLDatabase() db.addUser(“user”, name=”john”, password=”password”) db.createBatch(“batch”, name=batch_name, mode=”batch”) db .setDatabase(“user_name”, user_name) db .commit() This will create a batch of database objects called batch.
The batch is just a Python script that you can run to generate the database.
If you want to save the database as a CSV file, just type the following into your editor.
db.save() Now that we have the database created, we need to edit it to insert it into the database list.
In the previous code we created a database named user_Name and we have a batch named batch_name.
We can now open the database and insert a new user by typing in the name of the user we just created.
The first line of our database is the user name.
Next is the password.
Finally, we have our database name.
This should look like this in the database editor: Edit database in Postgresql Editor Now let’s try it out.
Open up the database in the Postgsql Editor.
Click on File->Edit…
Now you should get a bunch of blank lines on your screen.
Type in the username and password you just created and click OK.
Next, you need to select a database name from the dropdown list.
Here’s what the database name should look, if you go to the database dropdown menu.
You can select any database name and then click OK to delete it.
To insert a database, you simply select it and hit enter.
This will insert the database object into the list of databases.
This process is similar to creating a database.
It’s basically the same as adding a new object to the table.
Now that you’ve inserted the database, click on the “Delete” button and you should be taken to a dialog where you can delete the database or you can create a fresh database.
You should be prompted to save it.
This is done by typing the name that you just added in the drop-down menu and hitting enter.
You should be presented with a pop-up window with a bunch in it.
Choose the database you want and then hit enter to save your changes.
Now let’s create the batch to run the database from.
The script that created the database needs to be called in batch_list.py, which is a function that can be used in a script to create batches of data.
In a typical Python script, this function would look like the following: import postgresql from postgres import database db.batch_list() Now you’ll need to open up the batch file in your editor and run the script using the batch_add command.
The command line will look like: db.run() Now, the batch files are stored as a string file called “batch.txt” in the bin directory of your Postgsqql installation.
So, to run a batch, type the name and password that you used to create your database and press enter.
If all goes well, the database should now be in the list.
To create a CSV object, just use the name in the filename and hit type in a CSV filename, such as batch.csv, and the output will be a CSV string.
Here is an example: # Create a new batch of data from batch.txt db.bin(‘batch.csv’, mode=”csv”) # Save the data to batch.bin db.commit() You can see the output of the batch editor in the output pane of your editor window.
Now we’ll look at how to create our database.
To get started, type your database name in a file like batch_Name.sql, and hit save.
This database name is what you want the database to be named.
We’re going to create some database objects in the SQL editor, but the first step is to add them to the list that we just made.
You need to add a batch to the drop down menu, and then select the database that you created earlier.
Next, click the “Add” button, and add a new item to the “batch” list.
Then hit enter
