Final answer:
When performing a search on a(n) numeric column, the search condition does not need to be enclosed in single quotation marks.
Step-by-step explanation:
When performing a search on a(n) numeric column, the search condition does not need to be enclosed in single quotation marks. Numeric columns store numeric values such as integers or decimal numbers, and SQL interprets them as such. Here's an example:
SELECT * FROM grades WHERE score = 90;
In the example above, 'score' is assumed to be a numeric column so the search condition does not require quotation marks.
