Hello,

I have the below jdbc\_static lookup statement but it seems to fail with the error:-  
exception=\>#\<Sequel::Error: Mismatched number of placeholders (2) and placeholder arguments (1) when using placeholder string\>, :backt

```auto
{
            query => "SELECT b FROM local_table WHERE a = ? OR a = ?"
            prepared_parameters => ["[source][ip]","[destination][ip]"]
            target => "result_array"
            default_hash => {
                "b" => ""
}

```

Any advice or workaround ?

Thanks in advance!
