How to Efficiently Perform IN Lookups in PostgreSQL with Go?

Querying with IN Lookup in SQL Using Go

When executing an IN lookup in PostgreSQL using Go, the second parameter in the SQL query should be a Postgres-specific array object. This enables efficient evaluation of multiple values against the specified field.

To illustrate, consider the following SQL query:

SELECT * FROM awesome_table WHERE>

In Go, using the pq driver, you can construct this query as follows:

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

The pq.Array type allows you to create an array object from a slice of strings. In this example, the $2 parameter will be rendered as:

'{"this", "that"}'

This effectively translates to the following SQL:

SELECT * FROM awesome_table WHERE>

Note that prepared statements are used in this approach, ensuring that user inputs are sanitized to prevent SQL injection attacks.
