Re: Arrays

Saluton, I somehow get the impressions that support for arrays is not a high priority with PostgreSQL, even though I think it would be very handy. On the other hand, the system itself uses arrays e.g. for user groups, so I guess there should be readily available functions/operators for dealing with that, but I cannot seem to be able to find them. Is there a simple way of checking whether e.g. a given int4 is in a given int4-array? Is there a way to "thread" a command over an array? By this I mean: Given an array {1, 2, 3} and a table t like id | name --------|-------- 1 | joe 2 | fred 3 | mark , a call to select thread('||', t, {1,2,3}) should produce 'joefredmark'. Thanks in advance, Albert. -- -------------------------------------------------------------------------- Albert Reiner <areiner@tph.tuwien.ac.at> Deutsch * English * Esperanto * Latine --------------------------------------------------------------------------
