How do you use SQL Compare?

The COMPARE function in SQL is used to compare two expressions or values, returning one of three possible outcomes.

  1. If expression 1 is less than expression 2, return -1.
  2. Return 0 if expression 1 is equal to expression 2.
  3. Return 1 if expression 1 is greater than expression 2.

The method of using a comparison function is as follows:

SELECT COMPARE(expression1, expression2) AS result;

expression1 and expression2 can be any valid SQL expressions or values. The result will be returned as a new column named “result”.

– Paraphrase: I need someone to help me complete this task.

Suppose we have a table with numbers and we want to compare the values of two columns.

SELECT value1, value2, COMPARE(value1, value2) AS result
FROM numbers_table;

This will return a result set containing the original values and comparison results.
