使用 to_date ORACLE 立即格式化执行

Question

我卡在包内的格式化过程中.....脚本工作正常，但事实证明将其与包集成很困难！！

我不习惯 oracle...我有脚本运行但不在包中...好吧，不是全部...Drop Table worked

CREATE OR REPLACE PACKAGE BODY Testing is
    PROCEDURE DropTable1 IS         
        BEGIN
                execute immediate ('DROP TABLE mytable1');                           
        END;

    PROCEDURE PopulateTable1 IS
        BEGIN
            execute immediate ('CREATE TABLE mytable1
            AS (   
                select
                substr(t1.genarea,3,3) as M_Class,
                substr(t1.genarea,6,30) as M_Description,
                substr(t1.genarea,36,3) as M_Class,
                substr(t1.genarea,39,30) as M_Description,
                substr(t1.itemitem,1,3) as product_code,
                t3.CHANNEL_NUM as SALES_CHANNEL,
                to_date(''t2.time_id'',''dd-mon-yyyy'') as mis_date,
                sum(t2.ap_cw_cfi_irp+t2.ap_cw_issues_irp) as ap_gross,
                sum(t2.Ap_Cw_Cfi_Irp+t2.Ap_Revivals_Irp) as ap_net,
                sum(t2.sp_inc_irp+t2.sp_issues_irp) as sp_gross,
                sum(t2.sp_dec_irp+t2.sp_fs_irp) as sp_net
              from
                d_pr t1, act t2, age_map t3
              where
                t1.pfx=''IT'' and t1.coy=''1'' and t1.tabl=''T81'' and substr(t1.itemitem,1,3) = t2.product_id and t3.AGE_NUM = t2.age_id
              group by
                substr(t1.genarea,3,3),
                substr(t1.genarea,6,30),
                substr(t1.genarea,36,3),
                substr(t1.genarea,39,30),
                substr(t1.itemitem,1,3),
                t3.CHANNEL_NUM,
                to_date(''t2.time_id'',''dd-mon-yyyy'')
            )');
            COMMIT;
        END PopulateTable1;
END Testing;

谢谢

Answer 1

你不应该在 t2.time_id 周围加上引号。单引号用于表示字符串文字；这显然是专栏参考。

Answer 2

BEGIN
execute immediate ('CREATE TABLE mytable1 AS 
(select to_date(/*remove single quotes here*/t2.time_id/*and here*/,''dd-mon-yyyy'') as mis_date 
from (select current_date time_id from dual) t2)');
end;

并且在 select 查询的最后一行。因为它被视为字符串

Answer 3

您的代码中有两处看起来很奇怪：

to_date(''t2.time_id'',''dd-mon-yyyy'')

列周围不需要任何单引号，只需要字符串文字周围的单引号.将其更改为：

to_date(t2.time_id,''dd-mon-yyyy'')

如果您在多个地方遇到单引号问题，那么我建议您 Quoting string literal technique to avoid errors due to single-quotation marks in the string. For example, see

COMMIT;

对于 DDL 语句，您不需要 COMMIT，您只需要为 DML[=34= 提交] 声明。删除它。
