In MYSQL, which type of value should not be enclosed within quotation marks?
Show Hint
but strings and date literals must be enclosed.
- DATE
- VARCHAR
- FLOAT
- CHAR
The Correct Option is C
Solution and Explanation
must be enclosed within quotation marks — either single or double quotes.
DATE values are also written in quotes,
because they are treated as string literals representing a date format.
However, numeric data types like FLOAT or INT
should be written without quotes.
If a number is enclosed in quotes, it is treated as a string,
which can cause data type mismatches and errors in queries.
Therefore, the correct answer is FLOAT.
