Subject [jira] Updated: (DERBY-836) ResultSetMetaData.getColumnDisplaySize sometimes returns wrong values for DECIMAL columns
Date Mon, 17 Jul 2006 06:13:14 GMT
     [ http://issues.apache.org/jira/browse/DERBY-836?page=all ]

Mayuresh Nirhali updated DERBY-836:
-----------------------------------

    Attachment: derby836-v7.diff

After the commit of derby-v6 patch, 3 store tests and 5 nist tests failed in the nightly testruns.

These failures are due to missing canon file changes in the previous patch. I have created
a new patch (not including the previous diffs) and is posted now.

All the store and nist tests pass with derby-v7.diff and this patch is ready to commit.

> I've added output early on in jdbcapi/metadata_test.java (and hence the tests metadata.jar
and odbc_metadata.java) to show this issue:
> E.g. for embedded
> DECIMAL(10,0) -- precision: 10 scale: 0 display size: 12 type name: DECIMAL
> DECIMAL(10,10) -- precision: 10 scale: 10 display size: 12 type name: DECIMAL
> DECIMAL(10,2) -- precision: 10 scale: 2 display size: 12 type name: DECIMAL
> I will add this test output once DERBY-829 is fixed so as not to cause conflicts.
