`LIKE` is a SQL operator used for pattern matching in a string. It returns true if a string matches a specified pattern. For example, if you want to find all the names that start with the letter "J", you can use the `LIKE` operator as follows:
```
SELECT * FROM users WHERE name LIKE 'J%';
```
This will return all the users whose names start with "J".
`OR` is a logical operator used to combine two or more conditions in a SQL query. It returns true if any of the conditions is true. For example, if you want to find all the users who are either from New York or California, you can use the `OR` operator as follows:
```
SELECT * FROM users WHERE state = 'NY' OR state = 'CA';
```
This will return all the users whose state is either NY or CA.
