首先 ddic用户用户进入,su01,输入用户名(加入我新建立的dev),回车,建立一个用户 帐号,然后把设置 密码,profile选项中输入SAP_ALL(这个是SAP ALL 认证的意思),保存就可了。然后LOG OFF。 2.用新建立的DEV登陆,系统会提示你更改密码。更改,然后提示

帐号,然后把设置
密码,profile选项中输入“SAP_ALL”(这个是SAP ALL 认证的意思),保存就可了。然后LOG
OFF。
2.用新建立的“DEV”登陆,系统会提示你更改密码。更改,然后提示你是第一次登陆。然后 开
始破解了。
(这是显示的窗口)
3.SE38, 输入"LSKEYF00",然后点"DISPLAY", 找到 form JUMP_THE_WALL, 在
CALL 'GET_DEVELOPER_KEY' ID 'NAME' FIELD 'ABCDEFGHIJKL'
ID 'CUSTID' FIELD '1234567890'
ID 'KEY' FIELD DUMMY_KEY.
这里。设置断点(所谓设置断点,就是把光标放在这里。点击 ”红色stop“按钮)。
然后再T-CODE里面 “/o” 注意是英文字母o,不是零。然后回车,系统出来提示.
"generate new" OR "END SESSION"
你必须生成新的窗口,所以点击“generate new”。
系统的登陆后初始界面又出现了,现在又可以输入“se38”,进入ABAP/4 EDITOR的界面了.
(这是修改的窗口)
4, SE38, 输入 LSKEYF00,然后点"CHANGE", 这时回停在断点上,在
CALL 'GET_DEVELOPER_KEY' ID 'NAME' FIELD 'ABCDEFGHIJKL'
ID 'CUSTID'
FIELD '1234567890'
ID 'KEY' FIELD
DUMMY_KEY.
注意了:现在的画面是ABAP_DEBUGGER.模式.
中间显示的是灰色的.下面有FILED NAME .FILED VALUE两排输入框
输入"SY-SUBRC",然后回车.后面有个值,把它修改成 0, 然后点后面的小笔(修改)
然后"F6"
代码跳到下一个什么地方了,然后再次修改成0,然后点后面的小笔(修改)
然后"F6",然后"F8".
然后出来什么请求框,一路"对勾过去",然后会跳到"LSKEYF00"的编辑画面
然后"INSERT"这个按钮是可以按下的.
把光标停在你设端点的那行下面一行.然后点"INSERT"
在光标处会多出以下的字符
*{ INSERT REQUEST ID &$&$&$&$
1
*
*}INSERT
把中间的"*"退格删除.然后输入(如果不能输入.就在外面写好下面的话,CTRR+V可以过来
的,我机器TMD的就不能输入.最后我粘贴过来的.暴郁闷啊)
SY-SUBRC =0.
----->变成以下的样子
*{ INSERT REQUEST ID &$&$&$&$
1
SY-SUBRC =0.
*}INSERT
保险起见,在下一行 : CHECK SY-SUBRC EQ 2. "customer system!
后面可以加入上面同样的语句
然后点"EDIT-->CHECK-->SYNATX CHECK"检查语法是否出
错.
正确的话,最下面会有信息提示.你的输入是正确的.
这时你的最上面的 LSKEYF00 后面应该是 ACTIVE(REVISED)
然后保存.这时可能还会进入调试模式,再继续修改 SY-SUBRC 的值为0(按上面的步骤)
再保存,系统会弹出创建request的对话框,自己创建一个request,然后确定,整个过程就ok
了。
然后把2个窗口都关闭.从新--SE38.-->LSKEYF00 --显示看看.是加入的代码是 否已经进入.
这个文件了.
LOG OFF
SE38
现在可以创建程序了!

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
