Response in English: Optimizing a query in a database involves improving the efficiency of data retrieval. Here are two ways to optimize a query:1. Use Indexes: Indexes can drastically improve the performance of a query by reducing the number of records the query has to search through. The indexes allow the database engine to quickly locate the required rows, resulting in faster execution of the query. You can create indexes on columns that are frequently used in query conditions.2. Write Efficient Query Statements: The way you write your query statements can also have an impact on the querys performance. Avoid using the SELECT statement when retrieving data, as this will return all columns in the table, even those that are not needed. Instead, specify the columns you need in the SELECT statement. Additionally, using joins instead of subqueries can improve query performance, as joins usually execute faster. .
