我在下面的代码

上遇到了令人不安的错误
DECLARE
    CR_QUERY                INTEGER;
    CR_HANDLE               INTEGER;        
    V_COL1          VARCHAR2(40);
    V_COL2          VARCHAR2(18);
    N_ACTION                NUMBER(3);
    T_CREATE_TS             TIMESTAMP(6);
    V_COL3          VARCHAR2(60);

BEGIN
    CR_QUERY := DBMS_SQL.OPEN_CURSOR;
    DBMS_SQL.PARSE (CR_QUERY, I_V_QUERY, DBMS_SQL.NATIVE);
    DBMS_SQL.DEFINE_COLUMN (CR_QUERY, 1, V_COL1, 40);
    DBMS_SQL.DEFINE_COLUMN (CR_QUERY, 2, V_COL2, 18);
    DBMS_SQL.DEFINE_COLUMN (CR_QUERY, 3, N_ACTION, 3);
    DBMS_SQL.DEFINE_COLUMN (CR_QUERY, 4, T_CREATE_TS, 6);
    DBMS_SQL.DEFINE_COLUMN (CR_QUERY, 5, V_COL3, 60);

    CR_HANDLE := DBMS_SQL.EXECUTE (CR_QUERY);
    LOOP
        BEGIN
            EXIT WHEN DBMS_SQL.FETCH_ROWS (CR_HANDLE) = 0;

            DBMS_SQL.COLUMN_VALUE (CR_QUERY, 1, V_COL1, N_COLERR, I_ACTUAL_LEN);
            DBMS_SQL.COLUMN_VALUE (CR_QUERY, 2, V_COL2, N_COLERR, I_ACTUAL_LEN);
            DBMS_SQL.COLUMN_VALUE (CR_QUERY, 3, N_ACTION, N_COLERR, I_ACTUAL_LEN);
            DBMS_SQL.COLUMN_VALUE (CR_QUERY, 4, T_CREATE_TS, N_COLERR, I_ACTUAL_LEN);
            DBMS_SQL.COLUMN_VALUE (CR_QUERY, 5, V_COL3, N_COLERR, I_ACTUAL_LEN);

错误是错误(41,5):PLS-00307:“COLUMN_VALUE”的声明太多与此调用相匹配

有人会建议最新消息吗?

答案 0 :(得分:3)

问题在于:

DBMS_SQL.COLUMN_VALUE (CR_QUERY, 4, T_CREATE_TS, N_COLERR, I_ACTUAL_LEN);

如果将变量T_CREATE_TS定义为DATE,它应该可以正常工作,但是COLUMN_VALUE没有VALUE类型为TIMESTAMP的声明(至少在10.2中没有),因此它会抛出错误。
