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_afunc1in.xo.go
    path of file: ./repos/xo/_examples/a_bit_of_everything/oracle
    
    the code of the file until where you have to start completion: package oracle

// Code generated by xo. DO NOT EDIT.

import (
	"context"
)

// AFunc1In calls the stored functio
    
func AFunc1In(ctx context.Context, db DB, aParam int64) (int64, error) {
	// call a_bit_of_everything.a_func_1_in
	const sqlstr = `SELECT a_bit_of_everything.a_func_1_in(:1) FROM dual`
	// run
	var r0 int64
	logf(sqlstr, aParam)
	if err := db.QueryRowContext(ctx, sqlstr, aParam).Scan(&r0); err != nil {
		return 0, logerror(err)
	}
	return r0, nil
}
