DB2 FOR LUW / DB2FORLUW / A10 - DB2

In a DATE as TIMESTAMP(0) enabled database, the data type DATE 
should always be treated as TIMESTAMP(0).  However, when 
DB2_DEFERRED_PREPARE_SEMANTICS is enabled, a parameter marker 
that is set to the DATE data type will not be converted to 
TIMESTAMP(0).  This may not cause any problem at all, or there 
may be various symptoms depending on how the parameter marker is 
used. 
 
This example would not have any problem since the query only 
looks at the year: 
 
  select * from T where year(?) = year( current date ) 
 
The following query fails with SQLCODE -401: 
 
  select * from T where DATECOL < ? + 1 
 
The following query may return a wrong result because HOUR(?) 
always returns 0: 
 
  select * from T where hour(?) = hour( current date ) 
 
In the next example, the returned value will be a simple DATE 
(year, month and day) instead of the expected TIMESTAMP(0): 
 
  select ? from T
