NORMALIZE [ ON { MEETS [ OR OVERLAPS ] | OVERLAPS [ OR MEETS ] } ]

Syntax Elements

NORMALIZE
The result of the select is normalized on the first period column in the select list. Period values that meet or overlap are coalesced, that is, combined to form a period that encompasses the individual period values.
Any period columns that are specified after the first period column are treated as regular column values. Normalize is the last operation performed on the result of a SELECT statement. You can use a SELECT statement with the normalize clause on a normalized or non-normalized table.
A SELECT statement cannot normalize a derived period column.
ON MEETS OR OVERLAPS
Period values that meet or overlap are to be coalesced, that is, combined to form a period that encompasses the individual period values.
ON OVERLAPS
Period values that overlap are to be coalesced, that is, combined to form a period that encompasses the individual period values.
ON OVERLAPS OR MEETS
Period values that overlap or meet are to be coalesced, that is, combined to form a period that encompasses the individual period values.
