  • MDPROP_MEMBER (1) identifies a property of a member. This property can be used in the DIMENSION PROPERTIES clause of the SELECT statement.

  • MDPROP_CELL (2) identifies a property of a cell. This property can be used in the CELL PROPERTIES clause that occurs at the end of the SELECT statement.

  • MDPROP_SYSTEM (4) identifies an internal property.

  • MDPROP_BLOB (8) identifies a property which contains a binary large object (blob).

PROPERTY_NAME

DBTYPE_WSTR

The name of the property. If the key for the property is the same as the name for the property, PROPERTY_NAME will be blank.

A label or caption associated with the property, used primarily for display purposes. Returns PROPERTY_NAME if a caption does not exist.

DATA_TYPE

DBTYPE_UI2

The data type of the property.

CHARACTER_MAXIMUM_LENGTH

DBTYPE_UI4

The maximum possible length (in bytes) of the property, if it is a character or binary type.

Zero indicates there is no defined maximum length.

Returns NULL for all other data types.

DBTYPE_UI2

The maximum precision of the property, if it is a numeric data type.

Returns NULL for all other data types.

NUMERIC_SCALE

DBTYPE_I2

The number of digits to the right of the decimal point, if it is a DBTYPE_NUMERIC or DBTYPE_DECIMAL type.
