postgresqlHow can I use the WHERE IN array clause in PostgreSQL?

The WHERE IN array clause can be used in PostgreSQL to compare a set of values against an array of values. It is a shorthand form of multiple OR conditions and can be used to filter a result set.

For example, the following code block will select all rows from the 'users' table where the 'name' column contains any of the values in the array:

SELECT name FROM users
WHERE name IN ('John', 'Jane', 'Bob');

The output of this code will be a list of all users whose name is either 'John', 'Jane', or 'Bob'.

The code can be broken down into the following parts:

• SELECT name: This line specifies which columns to select from the table.
• FROM users: This line specifies which table to select from.
• WHERE name IN ('John', 'Jane', 'Bob'): This line specifies the criteria to filter the result set. In this case, it will return all rows where the 'name' column contains any of the values in the array.
