Hi thanks for the reply Archelle. I gone through the given link since i was new to this logstash env i was unable to get through it sample code attached below. You have attached a screen shot of the result which is needed. If you have any sample code kindly post it it will be really helpful parallely i will look into the link and try to create a solution. Thanks

Note : i have pasted the jdbc driver with in logstash-7.2.0\logstash-core\lib\jars that is why my
Jdbc_driver_libirary is empty

input {
jdbc {
jdbc_driver_library => ""
jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
jdbc_connection_string => "jdbc:sqlserver://DESKTOP-VHDBS6E\SQLEXPRESS:1433;databaseName=sa;"
jdbc_user => "sa"
jdbc_password => "sa"
statement => "Select id,name from department"
}
}

filter{
jdbc_streaming {
jdbc_driver_library => ""
jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
jdbc_connection_string => "jdbc:sqlserver://DESKTOP-VHDBS6E\SQLEXPRESS:1433;databaseName=sa;"
jdbc_user => "sa"
jdbc_password => "sa"
statement => "select Id as empid,emp_Name as empname from Employee where dept_Id = :code"

parameters => { "code" => "id"}
target => "employee_details"

}
}
output {
stdout { codec => rubydebug }
}

There you have it, just a few points though.

  1. Use deptid as alias of id field in input block.
  2. In your filter block, replace :code with :deptid, then under parameter,

parameters => { "deptid => "deptid”}
target => "employee_details"

                jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
                jdbc_connection_string => "jdbc:sqlserver://localhost:1433;database=db;user=arc;password=mipw"
                jdbc_user => "arc"
                statement => "select id as deptid, Name as deptname from department"
        }
