Status: Closed |
SQL0901 IS RETURNED FOR A QUERY THAT FETCHES ZERO-LENGTH LARGE OBJECTS ON DPF |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
In DPF, if a query is run that is selecting a large object, and
if that large object
has a length of 0, then a logic problem in the handling of the
object might return
an sql0901. The db2diag.log would show something like this:

| Local Fix: |
It might be possible to bypass the faulty logic by changing the
query to filter out
the zero-length large objects earlier in the access plan if
those results are not
needed. For example, adding a where clause like "where
length(clobfield) > 0. |
