How to Efficiently Execute IN Lookups in PostgreSQL using Go?

Executing IN Lookup in SQL Using Go

When using the IN lookup in PostgreSQL, the second parameter in the prepared SQL query expects a slice containing the values to be checked. The following code snippet demonstrates this:

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

This code will execute the following SQL query:

SELECT * FROM awesome_table WHERE>

Using a Postgres-Specific Array Type (pq Driver Only)

The pq driver for PostgreSQL provides an optimized method for using arrays in queries. By utilizing the pq.Array type, you can perform IN lookups more efficiently:

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

This code generates the following SQL query:

SELECT * FROM awesome_table WHERE>

Security Considerations

Remember to sanitize user inputs when using prepared statements to prevent SQL injection attacks.
