oracleパイプライン関数with with with with clause

Question

私はselect文の中でテーブルとして使用できるオブジェクトを返す関数を作成しようとしています。オラクルのドキュメントに関する調査によると、私はPIPELINED関数が必要であることを発見しました。 SQLでのパイプライン機能の構文に問題があります。前もって感謝します！

DROP TYPE ODSMaxVRSN_ROW; 
DROP TYPE ODSMaxVRSN_TBL; 

CREATE OR REPLACE TYPE ODSMaxVRSN_ROW

    sls_tran_key_unaud  int, 
    audit_sls_trans_key  int, 
    sls_4_part_key      varchar2(50), 
    sls_audit_rvsn_nbr  VARCHAR2(25) 
)

CREATE OR REPLACE TYPE ODSMaxVRSN_TBL AS TABLE OF ODSMaxVRSN_ROW

代わりのBULK COLLECTをやって、その後、テーブルの上にループ、あなただけのループでは一度に1行をフェッチし、配管みてください。ここをクリックしてください：http://www.oracle-developer.net/display.php?id=429

function GET_ODSMaxVRSN(in_dtFmt varchar2, 
         in_start_date varchar2, 
         in_end_date varchar2) 
     return ODSMaxVRSN_TBL pipelined is 

l_row ODSMaxVRSN_ROW; 
l_sql VARCHAR2(2000); 
l_cursor SYS_REFCURSOR; 

begin 

    l_sql := '--your query--'; 

    OPEN l_cursor FOR l_sql; 
    loop 
     fetch l_cursor into l_row; 
     exit when l_cursor%NOTFOUND; 

     pipe row (l_row); 

    end loop; 
    CLOSE l_cursor; 
    return; 
end GET_ODSMaxVRSN;
