Scalar functions

 

An EJB query contains scalar functions for doing type conversions, string manipulation, and for manipulating date-time values.

The list of scalar functions is documented in the topic EJB query: Scalar functions.

 

Example: Scalar functions

Find employees hired in 1999:

SELECT OBJECT(e) FROM EmpBean e where YEAR(e.hireDate) = 1999
The only scalar functions that are guaranteed to be portable across backend datastore vendors are the following:

The other scalar functions should be used only when DB2 is the backend datastore.
