%Library.List

datatype class %Library.List

ODBC Type: VARCHAR

When a %List data type value is projected to a client application, it exposes it as a syslist object. This allows the client application to efficiently manipulate the contents of the list.

Note that $List format is a compressed binary format; for this reason, a property of type of %List cannot be set through SQL nor can its value be queried through SQL (such as with a WHERE clause).

Refer to the documentation on $List in the ObjectScript Reference for more information.

classmethod LogicalToXSD(val As %List) as %String

Converts the ObjectScript $list value to the canonical SOAP encoded value.

classmethod OdbcToLogical(val="") as %String
