I would like to confirm the following with respect to the basic SQL Queries:
The float and real data types cannot be used with the equals and not equals operator in sql. If so then what else operators can i use for these data types.
Filtering based on the BLOB and XML columns is not allowed. So shall we disable any search based on these datatypes, also is there any other data type that cannot be filtered from the sql query?
 3. Also what kind of operators can i use for the timestamp data type.
