I don't know if you ever found the solution to this post you put up on the
hsqldb-developers list, I didn't see any replies. I hit the same problem
today and dug into the code and found the problem. In the TransferDb.java
class, getTableStructure(TransferTable TTable, DataAccessPoint Dest) method
(near the middle) there is a line that reads:
select_rs =
stmt.executeQuery(TTable.Stmts.sSourceSelect);
which executes a query against the Oracle database using query syntax it
does not seem to like (resulting in the following SQL Exception):
ORA-00911: invalid character
Cause: Special characters are valid only in certain places. If special
characters other than $, _, and # are used in a name and the name is not
enclosed in double quotation marks ("), this message will be issued. One
exception to this rule is for database names; in this case, double quotes
are stripped out and ignored.
Action: Remove the invalid character from the statement or enclose the
object name in double quotation marks.
Basically, it is objecting to the fact that there is a semicolon on the end
of the query. I modified my own code as follows:
select_rs =
stmt.executeQuery(TTable.Stmts.sSourceSelect.substring(0,TTable.Stmts.sSourc
eSelect.length()-1));
to remove the semicolon and things seem to work fine after that. It shows
up as a bland NullPointerException because the exception handling is written
to permit you to continue on uninterrupted after the failure despite never
getting a valid ResultSet in the col variable (there is an 'if' clause in
the catch block).
Perhaps an HSQL developer would be willing to have a look at the situation
and create a real patch?
