DB2 FOR LUW / DB2FORLUW / 910 - DB2

SQLExecute might incorrectly fail (return SQL_ERROR) when you 
pass it the statement handle for an 
"UPDATE ... WHERE CURRENT OF <cursor-name>" statement. If you 
then call SQLGetDiagRec it reports error SQL0519N. 
 
The problem happens if the "SELECT ... FOR UPDATE" statement 
associated with the cursor <cursor-name> 
has one isolation level and the "UPDATE .. WHERE CURRENT OF 
<cursor-name>" statement has a different isolation level set by 
using the SQL_ATTR_STMTTXN_ISOLATION or SQL_ATTR_TXN_ISOLATION 
statement handle attributes.

As a workaround, rather than setting the isolation level for 
individual statements set the isolation level for the 
connection instead. You can set the isolation level for the 
connection by setting the TXNISOLATION DB2 CLI/ODBC 
configuration keyword or by setting the SQL_ATTR_TXN_ISOLATION 
attribute for the connection handle.

Problem was first fixed in Version 9.1 Fix Pack 11. 
At a minimum, this fix should be applied on the client.
