EXECUTION OF A QUERY CONTAINING SCALAR SUBQUERY OUTPUT COLUMN REFERENCE MAY FAIL WITH SQL0901N IN A DPF ENVIRONMENT |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 980 - DB2 |
| Problembeschreibung: |
Execution of a query may fail with SQL0901N if the following
conditions are satisfied:
- Database is Data Partitioning Feature (DPF) enabled
- Query or a view it references or one of its nested subselects
contains a scalar subquery (SSQ) reference in the output column
list
- SSQ contains an equi-join predicate that directly references a
local column and a column from the query that references SSQ
- An SSQ output column (SSQOC) is from a base table or view (on
at least one base table) that is referenced inside SSQ
- SSQOC is used for output in the query column that references
SSQ
- SSQOC is not used in any predicates in the query that
references SSQ
The SQL0901N will look something like:
SQL0901N The SQL statement failed because of a non-severe
system error.
Subsequent SQL statements can be processed. (Reason "probe 030
in
sqlkt_pack_tuple(), msg=cold=NULLABLE zvalue=NONULLS col(".)
SQLSTATE=58004
Corresponding entries in the db2diag.log may look something
