Status: Closed |
DRDA WRAPPER REPORTS SQL0206N WHEN ACCESSING NICKNAMES POINTING TO DB2 LUW V95 DATA SOURCE OR EARLY VERSION |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
Users may receive SQL0206N error while accessing DB2 LUW V95
data source or early version via nicknames. The error message
shows as below:
SQL1822N Unexpected error code "-206" received from data source
"<your_server_name>". Associated text and tokens are " SQL0206N
"NULL" is not valid in the context where it is". SQLSTATE=560BD
The error is caused by the incorrect setting of server option
db2_null_in_select in wrapper. Because of the incorrect setting,
remote SQL like "SELECT ..., NULL, ... FROM TABLE1" may be
pushed down to the UDB data sources which do not support a
statement like that.
The problem only happens on Federation Server V95 with fixpack 8
or higher, V97 with fixpack 4 or higher. |
