Re: DDL's - tables and keys

Look at the ALWNULL parm of the DCLF command.

Thanks Charles,
Now I am being asked one additional question which I frankly cannot seem
to find the answer to......

Can a RECVF command in a CL read a record that has a null value?

Doug, a primary key can be one or more fields.

CREATE TABLE CTSC_W/DOUGTEST (
 FLD1 CHAR (10 ) NOT NULL WITH DEFAULT,
 FLD2 CHAR (5 ) NOT NULL WITH DEFAULT,
 FLD3 INT NOT NULL WITH DEFAULT,
 PRIMARY KEY (FLD1, FLD2))

HTH,

In looking at the manual it appears that the only option I have for

adding

a key is the primary key, at least at the table level.  If I want to use
more than one field I still have to create an index.

Since we still have some programmers using tables and indexes as if they
were PF's and LF's, I am trying to ascertain if there is any way to add

a

composite primary key to a table without an index?

I assume no from what I have read thus far......but if anyone knows of a
way or can offer clarification I would be most appreciative.
