SQL in AI and Machine Learning

SQL is the bridge between raw data and AI/ML models.

How SQL powers ML:

  • Data preparation - clean and transform training data
  • Feature engineering - create input variables for models
  • Training data extraction - select and label datasets
  • Model evaluation - query predictions vs actuals

Tools combining SQL and ML:

  • BigQuery ML - train models with SQL syntax
  • Snowpark - run ML in Snowflake
  • Amazon Redshift ML - SQL-based predictions

Most ML engineers spend 80% of their time on data preparation. SQL is essential for that work.

You don't need to choose between SQL and Python - the best data scientists use both.
