The EXPLAIN command provides information about how MySQL executes a query. The query is analyzed before it is executed to determine how and in which order tables will be joined. The EXPLAIN command also helps to determine if indexes will improve query performance.
The PROCEDURE ANALYSE() function examines and analyzes the query results. It provides information about the table's columns, such as minimum and maximum values and suggests optimal field types.
