You can define a partitioning expression that uses CASE_N with the built-in functions CURRENT_DATE or CURRENT_TIMESTAMP. Subsequently, you can use the ALTER TABLE TO CURRENT statement to re-partition the table data using a newly resolved current date or timestamp.

For more information, see “Rules and Guidelines for Optimizing the Reconciliation of CASE_N PPI Expressions Based On Updatable Current Date and Updatable Current Timestamp” in Teradata Vantage™ - SQL Data Definition Language Syntax and Examples, B035-1144.
