Which SQL function is used to find the highest value in a column?OptionsMIN()SUM()MAX()AVG()

Identifying the Function

1. Break Down the Problem

   • We need to determine which SQL function is used to find the highest value in a column from the given options.

2. Relevant Concepts

   • SQL provides several aggregate functions to perform calculations on multiple rows of a table:
     • MIN(): Finds the minimum value.
     • SUM(): Calculates the total sum of values.
     • MAX(): Finds the maximum value.
     • AVG(): Calculates the average of values.

3. Analysis and Detail

   • The question specifically asks for the function that identifies the highest value in a column. Among the options, MAX() is explicitly designed to retrieve the maximum or highest value.

4. Verify and Summarize

   • Upon review of the provided functions, MAX() is the correct function for finding the highest value in a column, distinguishing it clearly from the other functions which serve different purposes.

Final Answer

The SQL function used to find the highest value in a column is MAX().
