The DLURLSCHEME function returns the scheme from a DataLink value with a linktype of URL. The value will always be in upper case.

DataLink-expression
The argument must be an expression that results in a value with a built-in DataLink data type.

The result of the function is VARCHAR(20). 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.

The CCSID of the character string is the same as that of DataLink-expression.
