defdefault value of the column
max_lengthmaximum length of the column
not_null1 if the column cannot be NULL
primary_key1 if the column is a primary key
unique_key1 if the column is an unique key
multiple_key1 if the column is a non-unique key
numeric1 if the column is numeric
blob1 if the column is a BLOB
typethe type of the column
unsigned1 if the column is unsigned
zerofill1 if the column is zero-filled
resultresult comes from a call to cubrid_execute()
field_offset
The numerical field offset. If the field offset is not specified, the
next field (that was not yet retrieved by this function) is retrieved.
