If you are going to use a combination of three or more AND and OR conditions, it is often easier to use the NOT and NOT IN operators.
A. True
B. False
Answer: Option B
Solution (By Examveda Team)
In SQL, the NOT and NOT IN operators are used to negate conditions or exclude specific values from a result set, but they do not inherently simplify the use of complex combinations of AND and OR conditions.When dealing with complex conditions involving three or more AND and OR operators, using proper grouping with parentheses and logical operators (AND, OR) is typically the standard approach. The NOT operator is used to negate a condition, while NOT IN is used to exclude specific values from a query result.
For example:
Using NOT to negate a condition:
SELECT *
FROM table_name
WHERE NOT column_name = 'value';
Using NOT IN to exclude specific values:
SELECT *
FROM table_name
WHERE column_name NOT IN ('value1', 'value2');
However, neither NOT nor NOT IN operators directly replace the need for properly structuring complex conditions with AND and OR.
Conclusion:
The statement "If you are going to use a combination of three or more AND and OR conditions, it is often easier to use the NOT and NOT IN operators" is Option B: False. Hence, the correct answer is False.
