Subject [jira] Commented: (DERBY-836) ResultSetMetaData.getColumnDisplaySize sometimes returns wrong values for DECIMAL columns
Date Sat, 03 Jun 2006 00:17:30 GMT
    [ http://issues.apache.org/jira/browse/DERBY-836?page=comments#action_12414544 ] 

Daniel John Debrunner commented on DERBY-836:
---------------------------------------------

The code changes are fine but there are other tests, like odbc_metadata and upgrade, that
use the same test code. Can you run the derbyall suite and provide a patch for the other master
files that need to change?

> DECIMAL(10,0)
> max display width value:   -1234567890  length 11
> embedded : 11 correct
> client: 12 WRONG
> DECIMAL(10,10)
> max display width value:   -0.1234567890  length 13
> embedded : 13 correct
> client: 12 WRONG
> DECIMAL(10,2)
> max display width value:   -12345678.90  length 12
> embedded : 13 WRONG
> client: 12 correct
> 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.
