Welcome to the world of SQL scripts! If you’re looking to optimize your database management and querying processes, you’ve come to the right place. This guide will walk you through the various SQL scripts developed by Hari Sekhon, perfect for DevOps practitioners, DBAs, and anyone interested in data analytics.

Getting Started with SQL Scripts

The SQL scripts by Hari Sekhon are a collection designed to aid in the easy management of different databases like MySQL, PostgreSQL, AWS Athena, and Google BigQuery. They include useful features such as:

• Data integration with AWS CloudTrail.
• Billing queries for GCP services.
• Tuning and performance monitoring scripts for MySQL and PostgreSQL.

To get started, you’ll need to clone the repository from GitHub:

git clone https://github.com/HariSekhon/SQL-scripts.git

Once you’ve cloned the repository, you’ll find neatly categorized SQL scripts organized by functionality.

Understanding the Scripts via Analogy

Please imagine you are managing a busy restaurant. Each SQL script resembles a dedicated staff member performing specific tasks:

• The aws_athena_cloudtrail_ddl.sql script is like your head chef who ensures all ingredients (logs) are correctly prepared (set up) before they are used in cooking (querying).
• The bigquery_billing_*.sql scripts function as your accounting team, providing insights into customer spending and overhead costs, helping you manage your budget effectively.
• The mysql_info.sql acts like a quality control inspector, ensuring all dishes leave the kitchen meeting standards, by summarizing user and authentication records.
• Finally, the postgres_info.sql is akin to your restaurant manager overseeing operations and making sure each department (databases) is functioning smoothly.

Running the Scripts

You can quickly test the PostgreSQL and MySQL scripts using the corresponding Docker containers. For instance, the command for PostgreSQL would look like this:

docker run -it --rm -v $(pwd):/sql postgres:latest psql -f /sql/postgres_query_times.sql

By mounting your directory to the Docker container, you have immediate access to run all scripts effectively.

Troubleshooting

If you encounter any issues, here are some troubleshooting tips:

• Make sure Docker is installed and running properly on your machine.
• Verify that you have the right permissions to access the SQL scripts within the mounted directory.
• For MySQL-related scripts, ensure your MySQL server is set up and accessible.
• Check for typos in your script names and database configurations.
• Inspect your Docker logs for any runtime errors.
