The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Query/400 generates default values like when using JDFTVAL in an LF
or on OPNQRYF. An SQL query generates the NULL value.
To get the SQL to match the *QRYDFN, the selection in the SQL WHERE
clause, fields compared against literals or fields, must be changed to
use IFNULL(field, DEFAULT). I am sure the DEFAULT kwd is not accepted
there, so specify the default according to the default specification in
the field of the file. I suppose the same may be required for joined on
fields.? The SELECT list will have to use IFNULL(field, DEFAULT) for
presentation as well, if the NULL value should be replaced; VALUE() and
COALESCE() are available instead of IFNULL().
