Description

Why set up BigQuery locally on macOS?

Running the bq CLI on your Mac lets you version-control queries, automate jobs, and avoid the web UI. You gain faster workflows and can integrate BigQuery with IDEs like Galaxy.

What do I need before installing?

You need: macOS 10.15+, Homebrew, a Google Cloud Project with BigQuery API enabled, and billing turned on.Ensure you have a Google account with BigQuery permissions.

How do I install Google Cloud SDK with Homebrew?

Open Terminal and run:
brew install --cask google-cloud-sdk
The installer adds gcloud and bq binaries. If PATH isn’t updated, add source "/usr/local/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/path.bash.inc" to ~/.zshrc.

How do I initialize and authenticate gcloud?

Run gcloud init, sign in via browser, and select your project. Confirm with gcloud config list project. For service-account automation, use gcloud auth activate-service-account --key-file=KEY.json.

How do I verify the bq CLI is ready?

Check version with bq version.Run bq ls to list datasets. Any error about credentials usually means the project or auth step was skipped.

How do I run my first SQL query?

Execute:
bq query --use_legacy_sql=false "SELECT id, name, email FROM `myproj.analytics.Customers` LIMIT 10;"
Replace myproj with your project ID. --use_legacy_sql=false ensures standard SQL.

How can I script queries for ecommerce analytics?

Store SQL in a file, e.g., top_products.sql, then run:
bq query --use_legacy_sql=false --format=table < top_products.sql.This fits nicely into Galaxy, CI, or cron jobs.

Best practices for macOS BigQuery workflows?

Create separate service-account keys per environment, keep them in the Keychain or secrets manager, and set GCP_PROJECT in your shell profile. Use --format=json for script-friendly output.

Common mistakes and quick fixes

PATH not updated: If command not found: gcloud, source the SDK’s path script or restart Terminal.
Wrong project: “Access Denied” errors often mean the active project is wrong—run gcloud config set project PROJECT_ID.

How to Set Up BigQuery on macOS Example Usage


bq query --use_legacy_sql=false '
SELECT p.name, SUM(oi.quantity) AS units_sold
FROM `shop.OrderItems` oi
JOIN `shop.Products`  p ON p.id = oi.product_id
GROUP BY p.name
ORDER BY units_sold DESC
LIMIT 5;'

How to Set Up BigQuery on macOS Syntax


# Install SDK
brew install --cask google-cloud-sdk

# Initialize & auth
gcloud init
# OR for CI
gcloud auth activate-service-account \
       --key-file=svc-key.json \
       --project=shop-prod

# Basic query
bq query [GLOBAL_FLAGS] [QUERY_FLAGS] 'SQL'

GLOBAL_FLAGS:
  --project_id=PROJECT        # Overrides default project
  --location=us               # Dataset location

QUERY_FLAGS:
  --use_legacy_sql=false      # Standard SQL
  --format=prettyjson|csv     # Output format
  --batch                     # Queue job, don’t wait

Example (ecommerce):
bq query \ 
  --use_legacy_sql=false \ 
  --format=table \ 
  'SELECT o.id, o.order_date, o.total_amount, c.name
   FROM `shop.Orders` o
   JOIN `shop.Customers` c ON c.id = o.customer_id
   WHERE o.order_date >= DATE_SUB(CURRENT_DATE(), INTERVAL 7 DAY);'

Common Mistakes

Skipping project configuration. Running bq commands without setting the default project causes “Not Found” or “Access Denied.” Fix with `gcloud config set project YOUR_PROJECT`.
Using legacy SQL by default. Forgetting `--use_legacy_sql=false` leads to syntax errors for modern queries. Always add the flag or set `bq --use_legacy_sql=false` in `.bqrc`.
