使用存储过程将数据插入从其他表派生的表中

Question

我使用以下 sql 代码在从其他表派生后将数据插入到表中。我不是高级 PL/SQL 方面的专家。我想构建一个存储过程，以实现与此 SQL 代码相同的功能。这个想法是我将只执行该过程，它将加载数据而不是一次又一次地运行此代码。我尝试了一些示例，但都在编译时出错，并且大多数示例都是 SQL server 格式。

Insert into TABLE(ID,NBR,VALUE,DESCRIPTION,STATUS,FILLER,SOURCE_SYSTEM,DATE_LOADED_TIMESTAMP)
SELECT SUBSTR(COLUMN1,1,2) as ID,
SUBSTR(COLUMN1,3,3) as NBR,
SUBSTR(COLUMN1,6,14) as VAUE,
SUBSTR(COLUMN1,20,30) as DESCRIPTION,
SUBSTR(COLUMN1,50,1) as STATUS,
SUBSTR(COLUMN1,51,2) as FILLER,
SOURCE_SYSTEM as SOURCE_SYSTEM,
CURRENT_TIMESTAMP AS DATE_LOADED_TIMESTAMP
from TMP_TABLE;

This may help you:


        create or replace procedure your_procedure_name
        as
        begin 
        Truncate table TABLE;
        Insert into TABLE(ID,NBR,VALUE,DESCRIPTION,STATUS,FILLER,SOURCE_SYSTEM,DATE_LOADED_TIMESTAMP)
        SELECT SUBSTR(COLUMN1,1,2) as ID,
        SUBSTR(COLUMN1,3,3) as NBR,
        SUBSTR(COLUMN1,6,14) as VAUE,
        SUBSTR(COLUMN1,20,30) as DESCRIPTION,
        SUBSTR(COLUMN1,50,1) as STATUS,
        SUBSTR(COLUMN1,51,2) as FILLER,
        SOURCE_SYSTEM as SOURCE_SYSTEM,
        CURRENT_TIMESTAMP AS DATE_LOADED_TIMESTAMP
        from TMP_TABLE;

    COMMIT;
        end;

Test with:

    BEGIN
       your_procedure_name;
    END;
