dropPartMart() procedure1. Uses the accelerator name, datamart name, table name and partition name. Partition name can be the name of the partition or partition number (sysfragments.partn) The partition name or number should be a valid partition for the table. Call dropPartMart() first before doing the DEATCH Session A14 7
