Hi Trafodioners,

i want to get  data types of trafodion by jdbc metadata interface,  like this:
rs = connection.getMetaData().getTypeInfo();
while (rs.next()) {
    System.out.println(rs.getString(1));
}
the results are:
BIGINT
BIGINT SIGNED
CHAR
NUMERIC

NUMERIC UNSIGNED
DECIMAL

DOUBLE PRECISION
VARCHAR
DATE
TIME
TIMESTAMP
INTERVAL
INTERVAL
