DLLINKTYPE
The DLLINKTYPE function returns the link type value from a DataLink value.

Examples
- Given a DataLink value that was inserted into column COLA of a
row in table TBLA using the scalar function:
then the following function operating on that value:INSERT INTO TABLA VALUES( DLVALUE('http://dlfs.almaden.ibm.com/x/y/a.b','URL','A comment') )
Returns the value 'URL'.SELECT DLLINKTYPE(COLA) FROM TBLA
