I have a JDBC input hat looks like this:

```
  jdbc {
    type => "D"
    jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
    jdbc_connection_string => "jdbc:oracle:thin:@//nn.nn.nn.nn:1521/nn"
    jdbc_user => "nn"
    jdbc_password => "nn"
    statement => "select * from nnn"
    schedule => "0 * * * *"
    clean_run => true
    last_run_metadata_path => "/path/.logstash_jdbc_last_run"

```

i want my sql query to select only the load of the date. somethining like` where insert_date = current_date()` and skip the history of the table.

Is it possible to do ?

Thanks

Hi

You might be able to pull it off using environment variables. You'll have to define a variable in your system and capture it from logstash, so your `where` statement would look like `where insert_date = ${TODAY}`, and `$TODAY` is a system variable.

Check this out: [https://www.elastic.co/guide/en/logstash/current/environment-variables.html](https://www.elastic.co/guide/en/logstash/current/environment-variables.html)

Hope this helps
