Hi.

I have been asked to produce a report for a new game. The report needs to show the gamers unique id, gamer_number, his nickname, the average score of the best 5 scores he got playing the game during a specified period and a list of the top five scores that made this average.

e.g.:
gamerNumber;nickname;average;score1;score2;score3;score4;score5
91692656912;"nickname1";"14.33";29.85;21.03;7.38;6.73;6.66

The SQL shown below works if I do not have any parameters, but when I add the parameters, I get:
Caused by: org.postgresql.util.PSQLException: The column index is out of range: 1, number of columns: 0.
    at org.postgresql.core.v3.SimpleParameterList.bind(SimpleParameterList.java:53)

    at net.sf.jasperreports.engine.query.JRJdbcQueryExecuter.createStatement(JRJdbcQueryExecuter.java:230)


I am not too sure if this is possible, but I am trying to prepare a statement containing a crosstab:
SELECT
    gamehighscore.row_name[1] as gamer_number,
    gamehighscore.row_name[2] as nick_name,
    gamehighscore.row_name[3] as average_score, score1, score2, score3, score4, score5 from
    crosstab('SELECT ARRAY[g.gamer_number::text, pl.nick_name, (SELECT avg(tp.high_score) as myAvg
           from (select score as top_score from game_score t2 WHERE
           game_date BETWEEN ? AND ?
           and g.gamer_number=t2.gamer_number
           order by score desc limit 5) as tp)::text] as row_name,
           score::text as bucket, score from bet b
           left join player pl on g.gamer_number=pl.gamer_number
           WHERE g.game_date BETWEEN ? AND ? AND g.gamer_number=? order by score DESC limit 5')
as gamehighscore ( row_name text[], score1 numeric, score2 numeric , score3 numeric , score4 numeric , score5 numeric )

Running against Postgres 8.3.8 running on Windows XP. Tried with jdbc drivers 8.3-603.jdbc3 and 8.4-701.jdbc3

Is this possible? How do I escape the parameters within the crosstab? Is it the crosstab that is the issue even? Any help would be most welcome.

Thanks

Carl
