----------------------------------------
[~jamestaylor], what do you think about the 40 vs 2147483647?

> ResultSetMetaData.getColumnDisplaySize() returns bad values for varchar and
> varbinary columns. Specifically, for the following table:
> CREATE TABLE SERGIO (I INTEGER, V10 VARCHAR(10),
> VHUGE VARCHAR(2147483647), V VARCHAR, VB10 VARBINARY(10), VBHUGE
> VARBINARY(2147483647), VB VARBINARY) ;
> 1. getColumnDisplaySize() returns 20 for all varbinary columns, no matter the
> defined size. This should return the max possible size of the column, so:
> getColumnDisplaySize() should return 10 for column VB10,
> getColumnDisplaySize() should return 2147483647 for column VBHUGE,
> getColumnDisplaySize() should return 2147483647 for column VB, assuming that
> a column defined with no size should default to the maximum size.
> 2. getColumnDisplaySize() returns 40 for all varchar columns that are not
> defined with a size, like in column V in the above CREATE TABLE. I would
> think that a VARCHAR column defined with no size parameter should default to
> the maximum size possible, not to a random number like 40.
