## How to Handle Unused Return Values from Go\'s Exec() Method?

Addressing Unused Variables in Go

When utilizing the Exec() method for SQL statements, multiple values are returned. However, in cases where the variable representing these values (sqlRes in this scenario) is not required, it results in a compilation error due to its unused status.

To resolve this issue, the blank identifier (_) can be employed. As defined in the language specification, the blank identifier facilitates the dismissal of right-hand side values in an assignment. This enables the evaluation of the Exec() statement without retaining the returned values.

By replacing sqlRes with the blank identifier in the provided code, the compilation error will be eliminated:

<code class="go">stmt, err := db.Prepare("INSERT person SET name=?")
_, err = stmt.Exec(person.Name)</code>

This modification allows the code to successfully execute while ignoring the unnecessary return values.
