The SYSTEM.SETOPTINFO view displays the access optimization
plan of a section as specified by the SETOPT statement.
The information is stored in a series of segments of up to 64 bytes.
The access plan in SYSTEM.SETOPTINFO is used by the section
if the OPTFLAG column of SYSTEM.SECTION is set to 1.
SYSTEM.SETOPTINFO is initially empty, and it is updated whenever
ALLBASE/SQL processes a SETOPT statement. Table 8-32 System.Setoptinfo
