Default mappings between ABL data types and XML Schema data types

The following table shows the default mapping between ABL data types and XML Schema data types used with the read and write XML methods of temp-tables and ProDataSets. The third column shows the ABL-specific XML Schema data type attribute which is an extension to the basic XML Schema. This attribute is used for ABL data types that are not the default for the XML Schema data type.

Table 28. ABL data types mapped to XML Schema data types
ABL type	XML Schema type attribute	ABL-specific XML Schema data type attribute
BLOB	base64Binary	prodata:blob
CHARACTER	string	—
CLOB	string	prodata:clob
COM-HANDLE	long	prodata:comHandle
DATE	date	—
DATETIME	dateTime	prodata:dateTime
DATETIME-TZ	dateTime	—
DECIMAL	decimal	—
INT64	long Note: Prior to OpenEdge Version 10.1B, xsd:long mapped to ABL DECIMAL. This mapping is still treated as valid in ABL.	—
INTEGER (32 bit)	int	—
LOGICAL	boolean	—
RAW	base64Binary	—
RECID (32 or 64 bit)	long	prodata:recid
ROWID	base64Binary	prodata:rowid
HANDLE/WIDGET-HANDLE	long	prodata:handle

Note: The -noint64 startup parameter forces ABL to use the pre-10.1B mapping of xsd:long to ABL DECIMAL. You have some control over default data type mappings. The READ-XML( ) and READ-XMLSCHEMA( ) methods have override-default-mapping and field-type-mapping options. See Reading and Writing XML Data from Temp-Tables and ProDataSets.
