Problem IC74014
|
Status: Geschlossen |
SYS_CONNECT_BY_PATH FAILS WITH -901 WHEN VARCHAR2 COMPATIBILITY FEATURE IS NOT ENABLED. |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
On a database without the VARCHAR2 compatibility feature
enabled, SYS_CONNECT_BY_PATH may fail at execution with the
following error:
SQL0901N The SQL statement failed because of a non-severe
system error.
Subsequent SQL statements can be processed. (Reason
"sqlricc2 result type".)
SQLSTATE=58004
This will happen when the length of the first argument times two
plus the length of the second argument exceeds 4000. For
example:
CREATE TABLE connby ( name VARCHAR(2000), id INTEGER, pid
INTEGER );
SELECT SYS_CONNECT_BY_PATH( name, '/' )
FROM connby START WITH id = 1 CONNECT BY PRIOR id = pid;
The length of the first argument (name) is 2000, the length of
second argument is 1: 2*2000+1 = 4001 > 4000. |

| Local-Fix: |
If possible, cast the first argument such that the combined
length <= 4000. Note that this may result in truncation of the
result |
