Hi., as you said "The basic knowledge of SQL is enough to become etl tester" but may i know why people always say they work almost 80% on sql only as ETL tester?

To get started with ETL testing basic SQL is fine, we can start validating the basic ETL or ELT Loads. However, to test data warehouse its imperative to understand the internal logic of Stored Procedures, so that we can write the complex SQL queries required for testing, based on the mapping sheet provided.
