How do stored procedures contribute to the efficiency of data analysis using SQL?

Question

Options

• AStored procedures can't be used in conjunction with user-defined functions (UDFs).
• BStored procedures enable the execution of repetitive tasks, enhancing efficiency.
• CThey solely facilitate basic arithmetic operations.
• DThey limit data accessibility, hindering analysis.

• A
  2% (1)
• B
  92% (47)
• C
  2% (1)
• D
  4% (2)

Explanation

Stored procedures are precompiled blocks of SQL code stored in a database that can be called repeatedly, eliminating the need to rewrite complex queries each time - this is exactly why B is correct: they automate and streamline repetitive data tasks, reducing execution overhead and improving consistency. Option A is false because stored procedures work alongside UDFs; they can call UDFs internally to extend functionality. Option C is wrong because stored procedures handle far more than arithmetic - they manage transactions, conditional logic, loops, and complex multi-step queries. Option D is the opposite of reality; stored procedures actually improve data accessibility by providing a controlled, reusable interface to underlying data.

Memory tip: Think of a stored procedure as a "saved recipe" - you write it once, call it by name anytime, and the kitchen (database engine) already knows how to execute it efficiently without re-reading the instructions from scratch.
