Subject [jira] Updated: (DERBY-4208) Parameters ? with OFFSET and/or FETCH
Date Wed, 08 Jul 2009 00:07:14 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4208?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dag H. Wanvik updated DERBY-4208:
---------------------------------

    Attachment: derby4208c.stat
                derby4208c.diff

Uploading a slightly simplified version, which removes the special casing of
literals (code is generated uniformly when a row count is provided). This makes for less clutter
(e.g. two fewer args to the result set class/factory methods, only one range check instance).

> The new OFFSET/FETCH syntax does not support Parameters. 
> From ij against the toursdb I would like to do the following:
>     ij> prepare foo as 'select * from cities offset ? rows fetch first 10 rows only';
> but results in the following syntax error: 
>     ERROR 42X01: Syntax error: Encountered "?" at line 1, column 29.
> Parameterized OFFSET/FETCH is important for performance (can be prepared) and security
(SQL strings not created on the fly).
