How should I express today's date in sql in logstash?  
I tried this and it doesn't work. It throws error saying cannot convert VARCHAR '%{YYYY.DD.dd}' to DATE.  
Please help.

input {  
jdbc {  
....  
statement =\> "select \* from ... where date\_col=:'todayDate'  
parameters =\> { "todayDate" =\> "%{YYYY.DD.dd}" }  
....  
}  
}

It's typically easier to do this using a function that is supported by your database.

e.g., with postgres, if the `date_col`'s type were `date`, then you could use `WHERE date_col=CURRENT_DATE`
