Myrna van Lunteren updated DERBY-3057:
--------------------------------------
Attachment: DERBY-3057.diff_try1
I'm attaching a patch, which
1. implements the same functionality as JDBC.matches() for JSR169
I verified this works by having the elaborate if be the code executed for
jdk14 and running the test TableFuncionTest; that worked.
2. placing an if (JDBC.vmsupportJDBC3()) around a ResultSet.getBigDecimal() in
TableFunctionTest - this would give a method not found with JSR169
3. attempting to implement BinaryDecimal.setValueFromResultSet.
I have most doubts about item 3 - I implemented the method as:
+ data2c = resultSet.getBytes(colNumber);
+ sqlScale=0;
But although this seems to work for J2ME/JSR169, I have strong doubts.
Basically, I have little understanding of what this method should do, and I'm
not sure that it's enough to just get the bytes. Is it necessary to do some of
the manipulations found in this class to compress the bytearray obtained?
I'm also not clear on why this method wasn't implemented, and I've not done
much investigation in identifying where the j9/j2ME jvm chooses a different
code path than e.g. jdk142.
Feedback on this patch is appreciated.
