Sql last value can only store timestamp?

Hello,

Can anyone help me in this?
can sql last value stores only timestamp?
I am trying to use one number column using jdbc plugin and comparing it with sql last value.
I am getting an error, SQLSyntaxErrorException: ORA-00904: "SQL_LAST_VALUE": invalid identifier.

Regards,
Priyanka

No. tracking_column_type can be either timestamp or numeric.
