How to Perform an IN Lookup with a List of Strings in Go's `pq` Driver?

Performing IN Lookups in SQL Using Go

When executing SQL queries in Go, it's often necessary to incorporate an IN lookup. This operation involves searching for data within a specified list of values. In Postgres, this can be achieved using the IN operator, but it requires a specific format for the second parameter.

In the given code snippet:

stmt, err := db.Prepare("SELECT * FROM awesome_table WHERE>
Copy after login
Copy after login

The question arises: what should replace the question marks to execute the desired IN lookup?

SELECT * FROM awesome_table WHERE>
Copy after login
Copy after login

Answer:

To execute the IN lookup using the pq driver in Go, utilize pq.Array to represent the list of values:

stmt, err := db.Prepare("SELECT * FROM awesome_table WHERE>
Copy after login
Copy after login

This will generate SQL similar to:

SELECT * FROM awesome_table WHERE>
Copy after login
Copy after login

By using pq.Array, the list of values ("this" and "that") is converted into a Postgres-compatible array literal, enabling the IN lookup.

Remember that prepared statements should be employed for this approach, ensuring that inputs are properly sanitized.
