Обсуждение: Bug extracting money value

Hello!


I always get an exception when I try to extract the money value I inserted this way:

insert into public."dbtypes" ("cmoney") values ('7').

Java:
Object oValue = m_resultSet.getObject(i);

Stacktrace (postgresql-8.2dev-503.jdbc3.jar):
org.postgresql.util.PSQLException: Bad value for type double : ?7,00
    at org.postgresql.jdbc2.AbstractJdbc2ResultSet.toDouble(AbstractJdbc2ResultSet.java:2594)
    at org.postgresql.jdbc2.AbstractJdbc2ResultSet.getDouble(AbstractJdbc2ResultSet.java:1975)
    at org.postgresql.jdbc2.AbstractJdbc2ResultSet.internalGetObject(AbstractJdbc2ResultSet.java:132)
    at org.postgresql.jdbc3.AbstractJdbc3ResultSet.internalGetObject(AbstractJdbc3ResultSet.java:39)
    at org.postgresql.jdbc2.AbstractJdbc2ResultSet.getObject(AbstractJdbc2ResultSet.java:2291)

resultSet.getDouble(i);  doesn't work either.
resultSet.getString(i); returns '?7,00' without exception.

Tested with:
PostgreSQL 8.1.4 on Windows 2000
JDBC driver: postgresql-8.2dev-503.jdbc3.jar AND postgresql-8.1-407.jdbc3.jar

Thanks

"money" isn't a well-supported type on the server side (I believe its
use is no longer recommended) .. IIRC the formatting rules for it are
locale-specific, among other problems.

... though I'd expect at least getObject to work, if not getDouble()

Maybe you could dig into this and send us a patch?

Without having looked at the code, I think that the ? in getString()
comes from the backend formatting the Value with an EUR symbol, and the
JDBC driver looking for a $ to skip.

I now looked at the code.

It seems that the Code tries to strip brackets () and anything outside
of them, however, I did not get my backend to generate anything
containing brackets.

With the US locale, it generated '$5.00' and '-$5.00', with the european
locale, it generated '5.00' and '-5.00'.

This is still being debated, and will likely be reversed as there is
a proposal on the table for a new improved money type
