如何将动态光标传递到临时表中？

Question

我的临时表是 -

begin 
    stmt := Create local temporary TABLE 

      FMO_APP.DYNAMICSQL(ENGINE_FAMILY_CODE VARCHAR2(30 BYTE), 
           CONTRACT_NAME VARCHAR2(200 BYTE) NOT NULL 
           ENABLE, 
           CONTRACT_SEQ_ID NUMBER(9, 0) NOT NULL 
           ENABLE, 
           USAGE_MONTH VARCHAR2(10 BYTE), 
           INVOICE_NUM VARCHAR2(14 BYTE) NOT NULL, 

           INVOICE_AMT NUMBER(15, 2), 
           INVOICE_BILLING_DATE DATE, 
           CREATED_DATE DATE, 
           BILLING_INVOICE_TYPE VARCHAR2(255 BYTE), 
           EFH NUMBER(11, 3), 
           EC NUMBER(9, 0), 
           CANCELLED_INVOICE_NUM VARCHAR2(14 BYTE), 
           RESTORED_ESN VARCHAR2(12 BYTE), 
           PAYMENT_TERM_TEXT VARCHAR2(60 BYTE), 
           RECON_INVOICE_NUM VARCHAR2(1 BYTE), 
           RECON_PERIOD VARCHAR2(1 BYTE), 
           PAYMENT_DUE_DATE DATE, 
           CONTRACT_CODE VARCHAR2(4 BYTE) NOT NULL 
           ENABLE, 
           PRODUCT_LINE_CODE VARCHAR2(20 BYTE) NOT NULL ENABLE, 
           PAYMENT_STATUS VARCHAR2(50 BYTE), 
           RN NUMBER, 
           COUNT NUMBER) on Commit Delete Rows; 

    execute immediate stmt; 

    insert into FMO_APP.DYNAMICSQL (cur_result); --is this correct ? 

    end; 

动态游标是 -

open cur for v_sql; 
LOOP 
    FETCH cur 
    INTO cur_result; 
    EXIT WHEN cur%NOTFOUND; 

--v_sql is a dynamic query. 
--cur is ref_cur. 
--cur_result  dynamicsql%ROWTYPE; 

我需要从游标使用临时表来存储值，并用它后来更新表。

以下是完整的代码。

BEGIN 


usage_month_parameters := usage_month_array(); 

open cur for v_sql; 
LOOP 
    FETCH cur 
    INTO cur_result; 
    EXIT WHEN cur%NOTFOUND; 

    begin 
    stmt := Create local temporary TABLE 

      FMO_APP.DYNAMICSQL(ENGINE_FAMILY_CODE VARCHAR2(30 BYTE), 
           CONTRACT_NAME VARCHAR2(200 BYTE) NOT NULL 
           ENABLE, 
           CONTRACT_SEQ_ID NUMBER(9, 0) NOT NULL 
           ENABLE, 
           USAGE_MONTH VARCHAR2(10 BYTE), 
           INVOICE_NUM VARCHAR2(14 BYTE) NOT NULL, 

           INVOICE_AMT NUMBER(15, 2), 
           INVOICE_BILLING_DATE DATE, 
           CREATED_DATE DATE, 
           BILLING_INVOICE_TYPE VARCHAR2(255 BYTE), 
           EFH NUMBER(11, 3),

     else

     v_usage_month_arr(var_num) := usage_month_value_obj(cur_result.ENGINE_FAMILY_CODE, 

                  cur_result.CONTRACT_NAME, 
                  cur_result.CONTRACT_SEQ_ID,

您对Oracle临时表的理解是完全错误的。您需要创建它只有一次，任何存储的代码外（过程，函数，包）：

create temporary table my_temporary_table (...) on commit delete rows; 

之后，你就可以在任何地方使用它，你需要的。与数据使用insert ... select语句填充：

procedure my_proc (...) is 
    ... 
begin 
    insert into my_temporary_table (...) 
    select ... 
    from source_table; 

end; 

表将在提交之后被清除。
