Description: ResultSetMetaData. getColumnDisplaySize
() returns value
-1
Details:
ResultSetMetaData. getColumnDisplaySize
() returns value -1 for several
columns of answer set generated by DatabaseMetaData.getTables() method.
Columns 1,4 and 5 of answer set (columns "table_cat", "table_type", and
"remarks" respectively) are described to be of length -1. The other 2
columns of the answer set (columns 2 & 3) are described to be of length 64,
which makes more sense.
Is there a reason why -1 is returned for these columns?
Additionally, I don't understand why the data type of column 1 is described
as "OTHER", as opposed to all the other columns, which are of type "VARCHAR"
(attained through ResultSetMetaData.getColumnType() method).
Thanks, Sergio Lob

joining column's datatypes do not match
