Selecting database issue

[NateBet22]

I am new to using GitHub. Can anyone help me with this issue? The issue is that when I type my code/query, it says I need to select a database, but when I try to select a database, it just spins on the loading screen.

Please provide more context!

GitHub itself does not provide a built-in database.

If a tool is asking you to “select a database”, you are using either:

• A web app hosted on GitHub Pages
• A GitHub Codespace / dev container
• A browser SQL playground embedded in a repo

The spinner usually means no database server is running or configured.

Quick checks

1. Identify where you are running this:

• Browser web app
• VS Code
• Codespace

2. If VS Code or Codespace:

Open terminal and verify a database exists.

Example (SQLite):

ls *.db

Example (Postgres):

psql -l

If nothing returns, there is no database to select.

---

If project uses SQLite

Create one:

sqlite3 app.db

Then configure your app to point to app.db.

---

If project uses Postgres/MySQL

Start the service:

Postgres:

sudo service postgresql start

MySQL:

sudo service mysql start

Create database:

createdb mydb

Then select mydb.

---

Why it spins

The UI is waiting for a database connection.
None exists. So it waits forever.

---

Important

GitHub ≠ database host.
You must run or connect to your own database.

If you share

• Repo link
• Screenshot of where “select database” appears

Database Model: StayWell
Staywell finds and manages accommodation for owners of student accommodation in the Seattle Area. The company rents out and helps to maintain 1–5-bedroom properties located in two main areas in the city, Columbia City and Georgetown. This is done on behalf of property owners based both in the local area and throughout the United States. Each location is administrated by a different office, StayWell-Columbia City and StayWell-Georgetown.

StayWell wishes to expand its business. The current model relies on advertisements in student and university publications in print and online, but prospective owners and renters need to contact the offices and speak to an administrator on all matters relating to renting of properties. The office organizes maintenance services for a fee, which is also currently done via email or direct communication.

StayWell has decided that the best way to increase efficiency and move toward an e-commerce-based business model is to store all the data about the properties, owners, tenants and services in databases. This will mean that the information can be easily accessed. StayWell hopes that these databases can then be used in future projects such as mobile apps and online booking systems.

The data is split into several tables, shown below:

The OFFICE table shows the office number, office name, address, area, city, state, and ZIP code.

OFFICE table

OFFICE table

StayWell stores information about the owners of each property in the OWNER table. Each owner is identified by a unique owner number that consists of two uppercase letters followed by a three-digit number. For each owner, the table also includes the last name, first name, address, city, state, and ZIP code. Notice the owners are from across the United States. Although some apartments may be owned by a couple or a family, only the primary contact is given.

OWNER table

OWNER table

Each property at each location is identified by a property ID, as seen in the PROPERTY table. Each property also includes the office number that manages the property, address, floor size, the number of bedrooms, the number of floors, monthly rent per property, and the owner number. The property ID is an integer unique for each property.

PROPERTY table

PROPERTY table

The RESIDENTS table includes details about the residents living in each property. The RESIDENTS table includes the first name and last name for each of the residents, along with a resident ID. The PROPERTY_ID is the unique identification number of the property in which they are staying.

RESIDENTS table

RESIDENTS table

The SERVICE_REQUEST table shows requests that residents have put into the offices for maintenance. Each row contains a unique service ID number, the property ID, the category number associated with the type of work, the office managing the property, a description of the request, the current status of the request, the estimated hours to complete the request, the hours spent on the request, and the scheduled service date.

The SERVICE_CATEGORY table includes details of these services. The CATEGORY_NUM provides a unique number for the service, and CATEGORY_DESCRIPTION shows what the service is.

Task 1: Create a table named SUMMER_SCHOOL_RENTALS. The table has the same structure as the PROPERTY table shown on Page 1, except the PROPERTY_ID and OFFICE_NUM columns should use the NUMERIC data type, there should be no BDRMS column, and the MONTHLY_RENT column should be changed to WEEKLY_RENT.

To see the structure of the PROPERTY table, use the DESCRIBE PROPERTY; command.

Execute the command to describe the layout and characteristics of the SUMMER_SCHOOL_RENTALS table.

Add the following information to a single record in the SUMMER_SCHOOL_RENTALS table:

PROPERTY_ID : 13,
OFFICE_NUM : 1,
ADDRESS : 5867 Goodwin Ave,
SQR_FT : 1,650,
BDRMS : 2,
FLOORS : 1,
WEEKLY_RENT : 400,
OWNER_NUM : CO103
MySQL should return an error that a column does not exist. Determine which column in the above list is not in the SUMMER_SCHOOL_RENTALS and remove it. Run the query again to add the record to the table.

Hey @NateBet22 ,

The error is happening because you are trying to insert a column that does not exist in SUMMER_SCHOOL_RENTALS.

According to the task description, SUMMER_SCHOOL_RENTALS is based on the PROPERTY table with these changes:

• PROPERTY_ID → NUMERIC
• OFFICE_NUM → NUMERIC
• No BDRMS column
• MONTHLY_RENT renamed to WEEKLY_RENT

So in your INSERT list, the invalid column is BDRMS.

What you should try to do:

1. Run:

   DESCRIBE SUMMER_SCHOOL_RENTALS;

2. Compare the column names exactly with your INSERT statement.
3. Remove BDRMS from the INSERT.
4. Finally, run the INSERT again.

SQL column names must match the table definition exactly. If it’s not shown in DESCRIBE, you can’t insert into it.
