DLURLPATHONLY

>>-DLURLPATHONLY--(--datalink-expression--)--------------------><

The schema is SYSIBM.

The DLURLPATHONLY function returns the path and file name necessary to access a file within a given server from a DATALINK value with a linktype of URL. The value returned NEVER 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:
```
   DLURLPATHONLY(COLA)
```
will return the value:
```
   /x/y/a.b
```
