Purging an EIM Table
When purging data from the EIM table, use the TRUNCATE TABLE
statement. This is a fast, nonlogged method of deleting all rows in a
table. DELETE
physically removes one row at a time and
records each deleted row in the transaction log. TRUNCATE TABLE
only logs the deallocation of whole data pages and immediately frees
all of the space occupied by that table's data and indexes. The distribution
pages for all indexes are also freed.
