Hi! I have query in my logstash.config file. Where field "where" is:  
where column."Id" \> :sql\_last\_value  
But, in result, after run this I have  
column."Id" \> '2018-08-13 17:02:41.489705+0300'  
Why logstash get data last\_value instead Id?

Have you set the use\_column\_value option to be true?
