Using Caché Objects - InterSystems Documentation

Data Types
• INDEXSUBSCRIPTS — If present, specifies the number of subscripts used by the
property in indices, using a comma as a delimiter in the property value; the %CacheStorage
class uses this number. A value of 2 specifies that the first comma piece of the property
value is stored as the first subscript and the second comma piece of the property value is
stored as the second subscript.
• MAXLEN — Specifies the maximum number of characters the string can contain
• MAXVAL — Specifies the maximum allowed logical value for the data type.
• MINLEN — Specifies the minimum number of characters the string can contain.
• MINVAL — Specifies the minimum allowed logical value for the data type.
• ODBCDELIMITER — Specifies the delimiter character used to construct a %List value
when it is projected via ODBC.
• PATTERN — Specifies a pattern that the string must match. The value of PATTERN
must be a valid Caché pattern-matching expression.
• SCALE — Specifies the number of digits following the decimal point.
• TRUNCATE — Specifies whether to truncate string to MAXLEN characters, where 1
is TRUE and 0 is FALSE.
• VALUELIST — Used for enumerated (multiple-choice) properties. VALUELIST is
either a null string (“”) or a delimiter-separated list (where the delimiter is the first character)
of logical values. If a non-null value is present, then the property is restricted to
values in the list, and the validation code simply checks to see if the value is in the list.
• XSDTYPE — Declares the XSD type used when projecting XML Schemas.
