This started in the Coding/Syntax group but I moved it since it seems purely data-related at this point.

I am having some unexpected behavior with my DBC-living tables.

In the IDE, I have optimistic table buffering set on.

I created a DBC and then stuck a table in it. Then I made a primary key and some candidate keys. On all of the columns I am not allowing null values. In the field-level rule of a column called logically_deleted_yn (not a candidate or primary key), I have

   logically_deleted_yn= ;
     IIF(INLIST(logically_deleted_yn,"Y","N"),;
     logically_deleted_yn,.NULL.)

The behavior I expected was that if I entered anything in the column that was not "Y" or "N", the DBC would put a .null. value in there, and since they are not allowed I would get an error.

To test, I opened up a browse window and typed "G" in there and the DBC took it fine.

What happened?

In addition, I am allowed to APPEND BLANK, change the primary key column, and then APPEND BLANK again; I thought this would violate the uniqueness of all the other columns, since they would be blank and therefore have .null. in them.




Here's what GENDBC says my table looks like:

CREATE TABLE 'INVESTIGATOR_PATIENT_PPLTN.DBF' NAME 'INVESTIGATOR_PATIENT_PPLTN' (INVSTGTR_PATNT_POPLTN_ETHCY_ID N(16, 0) NOT NULL, ;
