> 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.
