You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: sf_afunc0in.xo.go
    path of file: ./repos/xo/_examples/a_bit_of_everything/mysql
    
    the code of the file until where you have to start completion: package mysql

// Code generated by xo. DO NOT EDIT.

import (
	"context"
)

// AFunc0In calls the stored function 'a_bit_of_everything.a_func_0_in() int' on db.
fun
    
func AFunc0In(ctx context.Context, db DB) (int, error) {
	// call a_bit_of_everything.a_func_0_in
	const sqlstr = `SELECT a_bit_of_everything.a_func_0_in()`
	// run
	var r0 int
	logf(sqlstr)
	if err := db.QueryRowContext(ctx, sqlstr).Scan(&r0); err != nil {
		return 0, logerror(err)
	}
	return r0, nil
}
