ABAP动态生成经典应用之Dynamic SQL Excute 程序
[日期：2006-10-23]     来源：sapsky  作者：sapsky     [字体：大 中 小]
 
开发说明：在SAP的系统维护过程中，有时我们需要修改一些Table中的数据，可是很多Table又不能直接在Tcode：SE16中修改，使用的SAP ID又没有调试数据修改权限，这时我们应该怎么样修改数据呢？思路--> ABAP程序中的SQL 更新语句谁都有权限执行，只要我们能动态生成修改该Table字段的ABAP CODE动态执行即可！
 
开发技术：
1.SQL代码编写技术
1.动态程序代码生成技术
2.ABAP动态程序执行技术
 
注意事项：
SQL语法一定要准确，修改条件准确，修改数据后不违法数据唯一性原则
 
程序代码：如下

程序实例：
 
1.程序执行界面，显示SQL CODE录入画面
 
 
2.我们要修改的数据，材料主数据Material Master Table：MARA中的材料CODE主键
SOH-DL3C ---> SOH-DL8C
3.数据修改SQL语句编写，这里就不详叙了
 
UPDATE MARA SET MATNR = 'SOH-DL3C' WHERE MATNR = 'SOH-DL8C'
                                    AND ERSDA = '20040310'
4.修改动态ABAP程序生成确认修改
5.动态程序执行

开发说明：在CBO的程序开发过程中，需要为Table准备大量的测试数据，手动录入效率低，不专业，我们可以采用其他的高级编辑工具(例如：EXCEL, EditPlus)按照Table数据存储结构准备好数据，最后保存为ASC的文本文件，通过执行下面开发的程序，下面的程序执行的功能就是把编辑好的文本文件上的数据上载到SAP对应的Table中，小程序非常实用，也适用于我们大量更新Table数据时使用，ABAPer们的手头必备啊！
 
开发技术：
1.文本文件上载技术
2.动态程序代码生成技术
3.ABAP动态程序执行技术
4.TXT文本文件对应用Table字段编辑技术
 
注意事项：
文件文件编辑过程中时间日期格式为 20060201 120000 表示 2006.02.01 12：00：00
文本文件中不能包含除字符，数字之外的其他特殊符号。假如Table中对应的字段数据为空时，在编辑数据时也对应该列为空。
