PostgreSQL的同時施加參數映射使用iBATIS

Question

存儲過程發生錯誤：

--- Check the newSubs-InlineParameterMap. 
--- Check the statement (query failed). 
--- Cause: 
org.postgresql.util.PSQLException: 
ERROR: wrong record type supplied in RETURN NEXT Where: 
PL/pgSQL function "getnewsubs" line 34 at return next 

功能細節是如下....

CREATE OR REPLACE FUNCTION getnewsubs(timestamp without time zone, timestamp without time zone, integer) 
    RETURNS SETOF record AS 
$BODY$declare

end if;

end loop; 
return ;

ALTER FUNCTION getnewsubs(timestamp without time zone, timestamp without time zone, integer) OWNER TO radius 

如果我從控制檯運行的功能它運行良好並給出正確的響應。但是，當通過Java使用它會導致上述錯誤。

錯誤的直接原因：一個或多個變量v_cpno,v_actno,v_usedt的數據類型與表cpnusage和account中的對應列不匹配。

更一般地說，你的plpgsql函數是不必要的複雜和模糊。可以用一小部分代碼來編寫。我簡化爲：

CREATE OR REPLACE FUNCTION getnewsubs(timestamp, timestamp, integer) 
    RETURNS TABLE (
    actno  int 
    ,actname text 
    ,actid  text 
    ,cpntypeid text 
    ,mrp  double precision 
    ,domname text 
    ,ctno  int 
    ,cpno  bigint 
    ,usedt  timestamp without time zone 
    ,expirydt timestamp without time zone 
    ,createdt timestamp without time zone 
    ,phone  text) AS 
$BODY$ 
DECLARE 
    r record; 
BEGIN 

FOR r IN 
    SELECT cpno, c.actno, usedt 
    FROM cpnusage c 
    JOIN account s ON s.actno = c.actno 
    WHERE usedt >= $1 
    AND usedt < $2 
    AND validdomstat(s.domno, $3) 
    ORDER BY c.usedt; 

LOOP 
    RETURN QUERY 
    SELECT a.actno 
     ,a.actname 
     ,a.actid 
     ,c.descr  -- as cpntypeid 
     ,l.mrp 
     ,s.domname 
     ,c.ctno 
     ,b.cpno 
     ,b.usedt 
     ,b.expirydt 
     ,d.createdt 
     ,a.phone 
    FROM account a 
    JOIN cpnusage b ON a.actno = b.actno 
    JOIN cpn d ON b.cpno = d.cpno 
    JOIN cpntype c ON d.ctno = c.ctno 
    JOIN ssgdom s ON a.domno = s.domno 
    LEFT JOIN price_class l ON l.price_class_id = b.price_class_id 
    WHERE validdomstat(a.domno, $3) 
    AND b.cpno = r.cpno 
    AND b.actno = r.actno; 
    AND isactivation(r.cpno,r.actno,r.usedt) IS TRUE 
END LOOP; 

RETURN; 

END; 
$BODY$ 
    LANGUAGE plpgsql VOLATILE; 
ALTER FUNCTION getnewsubs(timestamp without time zone, timestamp without time zone, integer) OWNER TO radius 

可能簡化爲單個RETURN QUERY。但我已經打敗了這匹死馬。
