Created column will use as DBconnect Rising Column setup is advisable?

[vin_ven27]

I am using DBconnect to pull data in database then the setup would be RISING.  Using SQL to select data from database. There are 3 dates from database column and I will convert to epoch time then the highest epoch time will be created as column (MaxDate) to be use as RISING COLUMN. 

Questions:

May i know if the MaxDate will work in RISING COLUMN?

If yes, I encountered "java.sql.SQLException: Parameter #1 has not been set." is there anyone could help? 

Or other ways cause our only choice is to use the date max to be able to pull the updated one. Thanks

The column used as the Rising Column must exist in the database.  That is, it must be something that can be included in the WHERE clause of a SELECT statement.  If you can compare the three dates using SQL then that might work.  The value used in the Rising Column must be in a format supported by your SQL database.
