Final answer:
Without explicit tables, it's impossible to write specific SQL commands, but generally, the SELECT statement, accompanied by WHERE and GROUP BY clauses, are used to filter and group data. Percentages can be calculated using COUNT and division by total rows.
Step-by-step explanation:
The question seems to be around how to write SQL queries to retrieve information from a given set of data related to baseball statistics. However, without explicit tables provided, it's impossible to write accurate SQL commands. Generally, to retrieve data, you would use SELECT statements along with conditions defined by WHERE clauses to filter the data as per the question's requirements. It's also important to consider data grouping which can be achieved using GROUP BY clauses and aggregation functions.
For example, if we wanted to find the percent of data that is at most two, assuming we have a table with hit information, the basic structure of the SQL command would be:
SELECT COUNT(
condition_column
) / (SELECT COUNT(*) FROM
table_name
) * 100 AS percent_at_most_two FROM
table_name
WHERE
condition_column
<= 2;
The actual column and table names would replace condition_column and table_name respectively. For the question about grouping data differently, this might involve using different columns for the GROUP BY clause or potentially restructuring the database schema to better represent the relationships between data.
