[Hsqldb-user] BUG?

[<loi...@bn...>]

Hi,
Here is an error I get with the last version of HSQLDB (alpha T). It works
fine
with 1.7.1!

Here are the details:
I create two tables and populate one:

create table DUAL ( DUMMY VARCHAR )
INSERT INTO DUAL VALUES(NULL)

create table TABLES_LIST (
name varchar(100) not null,
last_updated timestamp not null,
constraint PK_TABLES_LIST unique( name, last_updated ) )

The TABLES_LIST is used to know the date of the last update of a table from
an Oracle schema (Oracle -> HSQLDB) using audit.

If the structure or the data of an Oracle table have been modified, then, I
recreate the corresponding table in the HSQLDB database
and I repopulate this new table, then I update the TABLES_LIST with the
current date and the table name with this SQL statement:

insert into TABLES_LIST ( name, last_updated ) select ?, now() from DUAL where not exists (select 1 from TABLES_LIST where name = ?)

As I said earlier, it works fine with 1.7.1 version but with alpha-T, I get this exception:

11:42:14,097 FATAL [Module] Unable to create the Historique database!

        at org.hsqldb.jdbcConnection.prepareStatement(jdbcConnection.java:544)

Can you confirm me it is a bug? If not, what can I do to resolve this problem?

TIA,
Loic
