APAR status
Closed as program error.
Error description
When a SELECT statement contains a subquery, the database server will describe a column defined as not null incorrectly as nullable. For example, if the table is defined as: CREATE TABLE foo ( integer_col integer not null, serial_col serial not null, varchar_col varchar(250) not null ) ; When running the following select statement, the database server will describe the integer and varchar colums as nullable. The serial column is correctly described as "not nullable". select * from (select * from foo)
