Problem IC62916
|
Status: Closed |
CLI APPLICATION RECEIVES CLI0002W INSTEAD OF SQLSTATE=01003 FOR A QUERY AGAINST DB2 FOR Z/OS. |
| product: |
DB2 CONNECT / DB2CONNCT / 950 - DB2 |
| Problem description: |
A CLI application may receive a CLI0002W "Data Truncated"
warning message when executing a query against DB2 for z/OS,
when the expected warning is SQLSTATE=01003 "Null values were
eliminated from the argument of a column function."
When this warning is returned, DB2 for z/OS updates the
SQLWARN[1] field in the SQLCA to either an "N" (for
non-scrollable cursors) or "S" (for scrollable cursors). The
DB2 CLI driver does not expect a value for SQLWARN[1], and if it
does, it makes the assumption that data was truncated.
SQLSTATE=01003 will be returned when the query uses an aggregate
function like MAX() and the column contains NULL values. |

| Local Fix: |
On DB2 for z/OS there is a parameter called DISABSCL. If this
parameter is set to YES, and the cursor specified is a
non-scrollable cursor, then DB2 for z/OS will not return "N"
in SQLWARN[1]. So, setting DISABSCL=YES might workaround the
issue.
The db2cli.ini keyword IGNOREWARNINGS=1 can be used as well to
suppress all warnings, including the CLI0002W message. |

| Solution |
First fixed in DB2 UDB Version 9.5, Fixpack 6 |
| Workaround |
On DB2 for z/OS there is a parameter called DISABSCL. If this
parameter is set to YES, and the cursor specified is a
non-scrollable cursor, then DB2 for z/OS will not return "N" |
