The SET data type

The SET IBM^® Informix^® data type is a collection type that stores non-ordered unique elements of a specific base type. Unlike the LIST type, the elements of a LIST have no ordinal positions. Elements cannot be duplicated.

Genero BDL does not support the IBM Informix SET data type:

• It is not possible to define BDL variables with the SET type.
• The static SQL syntax does not support collection-related syntax elements:
  • DDL statements like CREATE TABLE cannot use the SET keyword for column types,
  • The collection-derived notation TABLE() is not allowed,
  • The SET { } literal syntax is not allowed.
  • The value IN identifier syntax is not allowed.
• The fgldbsch schema extractor will report an invalid data type if you try to get the schema for a table with a SET column.
