Problem IC73577
|
Status: Closed |
SQLEXECUTE OF "UPDATE ... WHERE CURRENT OF CURSOR-NAME" MIGHT INCORRECTLY FAIL WITH ERROR SQL0519 |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
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. |

| Local Fix: |
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. |
