在 Oracle 11g 中立即执行

Question

我正在尝试在 oracle 中创建一个脚本来搜索多个 table 并插入到我正在创建的临时文件 table 中，但是我在尝试这样做时遇到了一些错误数字以外的任何内容。

声明变量

    m_polCount NUMBER:= 0;
    m_product NUMBER:= 0;
    m_version NUMBER:= 0;
    m_plan NUMBER:= 0;
    m_policy NUMBER:= 0;
    m_pol_comm_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_pol_end_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_pol_status NUMBER:= 0;
    m_next_pre_renew_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_next_renew_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_last_renew_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_cover_no NUMBER:= 0;
    m_cover_name VARCHAR(240):= 'Test';
    m_cover_start_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_cover_end_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_sum_assured NUMBER:= 0;
    m_cover_layer NUMBER:= 0;
    m_cover_prem_layer NUMBER:= 0;
    m_premium NUMBER:= 0;
    m_loading_type NUMBER:= 0;
    m_loading_name VARCHAR(200):= 'Test';
    m_basic_prem_loading SMALLINT:= 0;
    m_loading_start_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_loading_end_date DATE:= TO_DATE('01-01-3000','DD-MM-YYYY');
    m_loading_perc NUMBER:= 0;
    m_loading_rate NUMBER:= 0;
    m_loading_prem NUMBER:= 0;
    m_calc_desc VARCHAR(240):= 'Test';
    m_inflation_rate NUMBER:= 0;
    m_agent_no NUMBER:= 0;

Table 已创建

错误

ORA-00917: 缺少逗号

如果我尝试以相同的方式计算日期，我会得到一个差异错误

插入语句

EXECUTE IMMEDIATE '
        INSERT INTO I233_ACTIVE_P4L_POLICY_DATA
        VALUES(
        '||m_product||',

        ''TEST3'',
        '||m_inflation_rate||',
        '||m_agent_no||')';

给我以下错误

ORA-00984: 此处不允许列

我在尝试使用相同方法插入任何 VARCHAR 字段时也遇到了同样的问题。

有什么方法可以使用立即执行将日期/varchar 字段插入到上面创建的临时 table 中？

以上所有语句都包含在一个 BEGIN , END 块中

谢谢

假设您无法避免动态 sql，请使用绑定变量。这样，您就不必担心数据类型转换等问题。

类似于：

execute immediate '
    INSERT INTO I233_ACTIVE_P4L_POLICY_DATA
    VALUES(:m_product,
           :m_version,
           :m_plan,
           :policy_rec.policy_no,
           :m_pol_comm_date, <----This field
           TO_DATE(''01-01-3000'',''DD-MM-YYYY''),
           :m_pol_status,
           TO_DATE(''01-01-3000'',''DD-MM-YYYY''),
           TO_DATE(''01-01-3000'',''DD-MM-YYYY''),
           TO_DATE(''01-01-3000'',''DD-MM-YYYY''),
           :m_cover_no,
           '''',
           TO_DATE(''01-01-3000'',''DD-MM-YYYY''), 
           TO_DATE(''01-01-3000'',''DD-MM-YYYY''),
           :m_sum_assured,
           :m_cover_layer,
           :m_cover_prem_layer,
           :m_premium,
           :m_loading_type,
           ''TEST3'',
           :m_basic_prem_loading,
           TO_DATE(''01-01-3000'',''DD-MM-YYYY''),
           TO_DATE(''01-01-3000'',''DD-MM-YYYY''),
           :m_loading_perc,
           :m_loading_rate,
           :m_loading_prem,
           ''TEST3'',
           :m_inflation_rate,
           :m_agent_no)'

        :m_basic_prem_loading,
        :m_loading_perc,
        :m_loading_rate,
        :m_loading_prem,
        :m_inflation_rate,
        :m_agent_no;
