Go
The database/sql package from the standard library provides methods for executing parameterized queries either as prepared statements or as one-off queries.
age := 27
rows, err := db.Query("SELECT name FROM users WHERE age=?", age)
In addition to database/sql you must also import an appropriate driver for
your database.
The specific format of the parameter placeholders (?, $1, etc) is not
specified by database/sql. That detail is determined by your selected driver
so check their documentation. For example the PostgreSQL driver
github.com/lib/pq supports numeric parameters that can be reused such as
in this snippet from their docs:
rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1
OR age BETWEEN $2 AND $2 + 3`, "orange", 64)
Additional options such as named parameters can be obtained using the github.com/jmoiron/sqlx package.
You can learn more about using SQL databases in Go in the database/sql documentation and through the go-database-sql tutorial.
