Robert Zeigler updated CAY-1095:
--------------------------------

    Attachment: cay-1095.patch

Patch includes fix for the issue + unit test to verify the fix.
Unit test also includes a test to ensure that hsqldb table creation inserts the 
"CACHED" keyword, since I didn't see anywhere where that was being explicitly 
guaranteed.

> Cayenne attempts to append precision information to DOUBLE types when 
> creating tables in hsqldb which results in a sql exception.

>             Project: Cayenne
>          Issue Type: Bug
>          Components: Cayenne Core Library
>    Affects Versions: 3.0
>         Environment: os x, hsqldb 1.8.0.10, java 1.5

> According to the documentation on hsql's website, hsqldb should support 
> precision on DOUBLE types, so the following:
> create table foo(bar DOUBLE(22)); 
> should be valid.  However, the docs are apparently out of sync with reality, 
> as the above produces the following feedback:
> java.sql.SQLException: Unexpected token in statement [CREATE CACHED TABLE foo 
> (bar DOUBLE(22]
> This is now documented in the following bug report:
> http://sourceforge.net/tracker/index.php?func=detail&aid=2048932&group_id=23316&atid=378131
> Cayenne's hsqldb adapter should work around this hsqldb problem by dropping 
> the precision statement for DOUBLE, resulting in sql like:
> create table foo(bar DOUBLE);
