SELECT
REPEAT('* ', ROW_NUMBER() OVER () - 1) AS pattern
FROM
information_schema.tables
LIMIT 20;

SELECT Clause:

REPEAT('* ', ROW_NUMBER() OVER () - 1) AS pattern: This part of the query is responsible for generating the pattern. It uses the REPEAT function to repeat the '*' character followed by a space for a specific number of times. The number of repetitions is determined by ROW_NUMBER() OVER () - 1.
FROM Clause:

FROM information_schema.tables: The FROM clause is a standard SQL clause that specifies the source of the data. In this case, it uses the information_schema.tables table, but the specific table chosen is not crucial for the query's purpose. It's a common practice to use any table that has enough rows for the desired pattern.
