DLURLCOMPLETE

>>-DLURLCOMPLETE--(--datalink-expression--)--------------------><
 

The schema is SYSIBM.

The DLURLCOMPLETE function returns the data location attribute from a DATALINK value with a link type of URL. When appropriate, the value includes a file access token.

The argument must be an expression that results in a value with data type DATALINK.

The result of the function is VARCHAR(254). If the argument can be null, the result can be null; if the argument is null, the result is the null value.

If the DATALINK value only includes the comment the result returned is a zero length string.

Example:

• Given a DATALINK value that was inserted into column COLA of a row in table TBLA using the scalar function:

     DLVALUE('http://dlfs.almaden.ibm.com/x/y/a.b','URL','a comment')
  

  then the following function operating on that value:

     DLURLCOMPLETE(COLA)
  

  will return the value:

     HTTP://DLFS.ALMADEN.IBM.COM/x/y/****************;a.b
  

  (where **************** represents the access token)
