Sql_last_value as new field

Hi,
is it posible to use the value of sql_last_value in a new field ?

i use the following config:

input
{
jdbc
{
jdbc_driver_library => "/usr/local/lib/db2jcc4.jar,/usr/local/lib/db2jcc_license_cisuz.jar"
jdbc_driver_class => "com.ibm.db2.jcc.DB2Driver"
jdbc_connection_string => xxxxxxx
jdbc_user => xxxxxxxx
jdbc_password => xxxxxxx
statement => "SELECT ....., ........, .......... from .......... where ............. >:sql_last_value"
use_column_value => true
tracking_column => ...........
tracking_column_type => "timestamp"
schedule => "* * * * "
}
}
filter
{
mutate
{
replace => [ "message", "........." ]
gsub => [ 'message','\n','']
add_field => { "last_polling_time" => "%{sql_last_value}"}
remove_field => [ ".........." ]
}
if [message] =~ /^{.
}$/
{
json {
source => message
}
}
}
output
{
elasticsearch {
........... }
}

i will get

..........
..........
"last_polling_time": "%{sql_last_value}",
.........
..........

in the Output.

I haven't tried it, but I think you could add the placeholder to the columns of your statement like this?
"SELECT :sql_last_value as last_polling_time, ...FROM ..."

(You are aware that this will contain the highest timestamp of your previous request, not the most recent one?)

Hi Jenni

Yes i'm aware about it, but thx for the hint :slight_smile:
