Hey there,

I recently began to use the JDBC Plugin, which will be used to copy data (log data to be specific) from a table within an oracle database. Data is written there every few minutes later on and I just want to update the elasticsearch instance with every new row. While this seems to be working fine, I got 1 issue, which should be easily solveable, although I dont know how, yet.

The value for sql\_last\_value equals the timestamp, when the query was executed. But I would like it to be the latest date in my table.  
For example, this a query, extracted from the log file:  
SELECT \* from Log WHERE LOG\_TIME \> TIMESTAMP '2017-08-10 11:38:00.253000 +00:00'

But the newest data row is placed around march this year. With every minute, the query is executed again, and the value from sql\_last\_value is adding one minute.

This is my configuration:  
jdbc {  
jdbc\_connection\_string =\> "jdbc:oracle:thin://@DB:PORT:SID"  
jdbc\_user =\> "USER"  
jdbc\_password =\> "PASSWORD"  
jdbc\_driver\_library =\> "/home/logadmin/Downloads/ojdbc.jar"  
jdbc\_driver\_class =\> "Java::oracle.jdbc.driver.OracleDriver"  
tracking\_column =\> "LOG\_TIME"  
tracking\_column\_type =\> "timestamp"  
statement =\> "SELECT \* from ISI\_Log WHERE LOG\_TIME \> :sql\_last\_value"  
type =\> "db"   
schedule =\> "\*/1 \* \* \* \*"  
}

Is this even possible to archieve?

I think you need to add `use_column_value => true`

When doing that, I get the following message after every query:  
[2017-08-31T15:07:00,308][INFO][logstash.inputs.jdbc] (0.000000s) SELECT \* from ISI\_Log WHERE LOG\_TIME \>= TIMESTAMP '1970-01-01 01:00:00.000000 +01:00'  
[2017-08-31T15:07:00,308][WARN][logstash.inputs.jdbc] tracking\_column not found in dataset. {:tracking\_column=\>"LOG\_TIME"}

The time never changes and is always from the year 1970.
