What is the difference between “and” and “or” in SQL?

In SQL, AND and OR are logical operators used to connect multiple conditions.

1. AND: When multiple conditions are connected with AND, the entire condition will only be satisfied if all conditions are met simultaneously. In other words, all conditions must be true in order to return True.

Retrieve all data from the table where column1 equals ‘value1’ and column2 equals ‘value2’.

1. OR: When multiple conditions are connected using OR, the entire condition will be satisfied as long as any one of the conditions is met. In other words, it will return True as long as one of the conditions is true.

For example, retrieve all data from the table where column1 is equal to ‘value1’ or column2 is equal to ‘value2’.

Therefore, the difference between AND and OR lies in the way the conditions are connected, as AND requires all conditions to be true, while OR only requires one condition to be true.
