MySqlError { ERROR 1210 (HY000): Incorrect arguments to mysqld_stmt_execute } occurs when an empty string is bound to a parameter

Hi, thanks for giving us such a nice crate.

I would like you to advise me something about the issue which I'm facing.

When I run the following code, I get MySqlError { ERROR 1210 (HY000): Incorrect arguments to mysqld_stmt_execute }.

pub fn update_title(transaction: &mut Transaction) -> Result<(), mysql::error::Error> {
    transaction.prep_exec(r"
        update notebook_history
        set
            title = :title
    ", params! {
        "title" => "",
    })?;

    Ok(())
}

I guess that if an empty string is bound to a parameter, such an error occurs.

Is there any way to bind an empty string to a parameter without having an error?

Thanks.
