🤔 THE QUESTION

How can we expose a PySpark DataFrame as a queryable SQL table within the current SparkSession or across the entire cluster?

💡 WHAT IS IT?

createOrReplaceTempView() binds a DataFrame to a local session SQL name, while createOrReplaceGlobalTempView() shares it across all application sessions in global_temp.

🎯 WHAT IS IT USED FOR?

Enabling SQL-fluent analysts and BI tools to query programmatic DataFrame transformations directly with ANSI SQL.

💻 EXAMPLE

df.createOrReplaceTempView("v_sales_transactions")
df_high_value = spark.sql("SELECT * FROM v_sales_transactions WHERE amount > 5000")
