Hi,
on testing our auto-configuration persistence framework ACP against
PostgreSQL we found the following problem:
I have a table with a column of type numeric(48,10). The PostgreSQL docs
say: "The type numeric can store numbers of practically unlimited size and
precision, while being able to store all numbers and carry out all
calculations exactly."
I store the Double value 1212121234.5634349876 with a
PreparedStatement.setDouble()
I make a PreparedStatement with SELECT FROM TESTTABLE WHERE TESTCOLUMN=?
and set the Parameter with
stmt.setDouble(1, new Double(1212121234.56343498));
The row will be found!
The same happens when I do
stmt.setString(1, String.valueOf(new Double(1212121234.56343498)));
and if I do
stmt.setDouble(1, new Double(1212121234.5634349));
an error is produced : Unable to identify an operator '=' for types
'numeric' and 'double precision'
it seems to me, the behaviour with numeric datatypes is not consistent.
