What is the Difference Between Nor and Or?
🆚 Go to Comparative Table 🆚The main difference between "nor" and "or" lies in their usage:
- Or:
- Connects different possibilities.
- Used to present alternatives.
- Can be used without "neither" as long as the sentence is not negative.
- Example: Is it Tuesday or Wednesday today?.
- Nor:
- Always used in the negative, usually before the second or last of a set of negative possibilities.
- Used after "neither".
- Connects negative alternatives.
- Example: He drinks neither wine nor beer.
In negative sentences that mention two alternatives, "nor" is typically used alongside "neither" or when "not" is used to negate a statement. However, "or" can also be used in negative sentences, especially when "neither" is not used to introduce the first alternative.
Comparative Table: Nor vs Or
The search results provided do not directly address the difference between "nor" and "or." However, I can provide a simple explanation based on the given question.
It seems that there might be a misunderstanding in the question. "Nor" and "or" are not related to creating tables in SQL. Instead, they are logical operators used in SQL queries to combine conditions or expressions. Here are the key differences between "nor" and "or":
| Operator | Meaning |
|---|---|
| nor | Logical negation of "or". It returns a result if both conditions are false. In other words, it returns true if both conditions are false. |
| or | Logical disjunction. It returns a result if at least one of the conditions is true. In other words, it returns true if at least one of the conditions is true. |
In SQL, you can use these operators to filter records based on multiple conditions. For example:
SELECT *
FROM my_table
WHERE column1 > value1 OR column2 < value2;
In this example, the query will return records where either column1 is greater than value1 or column2 is less than value2.
Please note that the search results provided are not directly related to the topic of "nor" and "or" operators in SQL. They mostly discuss other SQL concepts, such as creating tables and using temporary tables.
