Обсуждение: two dimensional arrays supported?

Hallo,

i just tested to access a 2-dimensional array of varchar via jdbc and the
driver gives the exception "not implemented" - did i something wrong, or is
it not yet supported?

Any alternative available?

My table is defined as following:

CREATE TABLE tst_2dimarray
(
   twodim varchar[][]  NULL,
   onedim varchar[]  NULL
);

my code snippet:

Array a=rs.getArray("twodim");
String aa[][]=(String[][])a.getArray();//this line throws exception below

org.postgresql.util.PSQLException: Diese Methode ist noch nicht implementiert.
    at org.postgresql.Driver.notImplemented(Driver.java:413)
    at org.postgresql.jdbc2.Array.getArray(Array.java:106)
    at org.postgresql.jdbc2.Array.getArray(Array.java:63)
    at twodimarray.main(twodimarray.java:38)

localized message means "not yet implemented"...
Above code works fine with "onedim".

Only 1D arrays are currently supported.

ResultSet.getString() should give you the raw value, you can then parse
that yourself as needed.

I've tried unsubscribing with no luck. Administrator can you help me out? I
only use two addresses and neither one has worked using theunsubscribe tool.


Thanks.
