Ignititedb defines a date type in a field.
JdbcResultSet uses the getBytes function (org.apache.ignite.internal.jdbc2)
Because the field will be java.sql.Date type, there will be an exception to
the last else.
How to deal with it?
@Override public byte[] getBytes(int colIdx) throws SQLException {
Object val = getValue(colIdx);
if (val == null)
return null;
Class<?> cls = val.getClass();
if (cls == byte[].class)
return (byte[])val;
else if (cls == Byte.class)
return new byte[] {(byte)val};
else if (cls == Short.class) {
short x = (short)val;
return new byte[] {(byte)(x >> 8), (byte)x};
}
else if (cls == Integer.class) {
int x = (int)val;
return new byte[] { (byte) (x >> 24), (byte) (x >> 16), (byte)
(x >> 8), (byte) x};
}
else if (cls == Long.class) {
long x = (long)val;
return new byte[] {(byte) (x >> 56), (byte) (x >> 48), (byte) (x
>> 40), (byte) (x >> 32),
(byte) (x >> 24), (byte) (x >> 16), (byte) (x >> 8), (byte)
x};
}
else if (cls == String.class)
return ((String)val).getBytes();
else
throw new SQLException("Cannot convert to byte[]: " + val,
SqlStateCode.CONVERSION_FAILED);
}
