Hello,

The Firebird-Database 2.1 contains a LIST function

http://www.firebirdsql.org/rlsnotes/Firebird-2.1-ReleaseNotes.pdf



The LIST Function
Oleg Loa
Dmitry Yemanov
(v.2.1) This function returns a string result with the concatenated
non-NULL values from a group. It returns NULL if there are no non-NULL values.
FormatData Manipulation Language (DML)
44
<list function> ::=
  LIST '(' [ {ALL | DISTINCT} ] <value expression> [',' <delimiter value>    ] ')'
<delimiter value> ::=

      { <string literal> | <parameter> | <variable> }


Is there any equivalent in ORACLE 9?

It seems that there is a COLLECT function in Oracle 10i
(http://www.adp-gmbh.ch/blog/2005/march/28.html)
But not so easy to use like LIST in FireBird.
