Cognos implements the ISO-SQL CAST function which can be used to convert several source to target data type combinations
CAST ( x, DATE ) where x is a timestamp will convert the value to a DATE, effectively removing any time value x held.
Keep in mind, some vendors SQL DDL may have the keyword DATE, but in reality their implementation is a timestamp (i.e. ORACLE).
As applicable, the expression will be generated in a SQL statement using the vendor's implementation of CAST or their equivalent.
