Problems 17–21 are based on the following query: SELECT V_CODE, V_NAME, V_CONTACT, V_STATE FROM VENDOR WHERE V_STATE = 'TN' ORDER BY V_NAME; Assume that you have 10,000 different products stored in the PRODUCT table and that you are writing a web-based interface to list all products with a quantity on hand (P_QOH) that is less than or equal to the minimum quantity, P_MIN. What optimizer hint would you use to ensure that your query returns the result set to the web interface in the least time possible? Write the SQL code.

Problems 17–21 are based on the following query:

SELECT V_CODE, V_NAME, V_CONTACT, V_STATE
FROM VENDOR
WHERE V_STATE = 'TN'
ORDER BY V_NAME;

Assume that you have 10,000 different products stored in the PRODUCT table and that you are writing a web-based interface to list all products with a quantity on hand (P_QOH) that is less than or equal to the minimum quantity, P_MIN. What optimizer hint would you use to ensure that your query returns the result set to the web interface in the least time possible? Write the SQL code.

Expert Solution
Program Plan Intro

Optimizer hint:

  • Special instructions that are embedded inside the SQL command test for the optimizer is called as optimizer hints.
  • They are three kinds of hint namely:
    • ALL_ROWS
      • It minimizes the overall time of the execution by instructing the optimizer.
    • FIRST_ROW
      • It minimizes the need for executing the first set of rows by instructing the optimizer.
    • INDEX(name)
      • The optimizer is forced to use the index to process the query.

Explanation of Solution

Writing the query that utilizes least amount of time in processing:

  • It is recommended to use the FIRST_ROWS optimizer hint because it will reduce the time that is taken in returning the first set of rows to the application.

Query:

  • The query will lis...
