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: sp_a1in1out.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"
	"database/sql"
)

// A1In1Out calls the stored procedure 'a_bit_of_everything.a_1_in_1_out(number) numb
    
func A1In1Out(ctx context.Context, db DB, aParam int64) (int64, error) {
	// call a_bit_of_everything.a_1_in_1_out
	const sqlstr = `BEGIN a_1_in_1_out(:a_param, :a_return); END;`
	// run
	var aReturn int64
	logf(sqlstr, aParam)
	if _, err := db.ExecContext(ctx, sqlstr, sql.Named("a_param", aParam), sql.Out{Dest: &aReturn}); err != nil {
		return 0, logerror(err)
	}
	return aReturn, nil
}
