I've seen documentation about using parameters as

```auto
    statement => "select * from WORLD.COUNTRY WHERE Code = :code"
    parameters => { "code" => "country_code"}

```

But I'm in situation where I have 9 different cases and I store each case on a field called `linkedserver`, each case will have linked servers to get the data from.  
it will be like `select * from [linkedserver9].WORLD.COUNTRY WHERE Code = code1`

I've tried

```auto
 statement => "select * from [:linkedserver]WORLD.COUNTRY WHERE Code = :code"
    parameters => { "code" => "country_code" "linkedserver"=>"linkedserver"}

```

but it returning some exception

```auto
        [0] "_jdbcstreamingfailure",
        [1] "_jdbcstreamingdefaultsused",

```

Acctually I can do it by calling jdbc\_streaming filter on every if case (calling jdbc\_streaming 9 times), But using parameters on `FROM` could saving lot of lines.  
Question in, Can we use parameters on `FROM`
