Description: 这个是sql嵌入到c语言中的例子
原来：EXEC SQL CONNECT TO SKY.exp USER sa.sa //连接到数据库
更改：EXEC SQL CONNECT TO 8BC1D82B889C4FF.xixi USER sa. //连接到数据库
我装sql server时没改名，名字就叫8BC1D82B889C4FF
xixi是一个数据库的名字
sa的密码为空。
-This is the sql embedded c language in the original example: EXEC SQL CONNECT TO SKY.exp USER sa.sa// connect to database changes: EXEC SQL CONNECT TO 8BC1D82B889C4FF.xixi USER sa.// Connect to the database when I installed sql server did not change its name, the name of a database called 8BC1D82B889C4FFxixi is the name of the sa password is blank.

Description: 这是关于SQL，ORACLE，方面的书
In the Introduction and Chapter 1, PL/SQL Concepts, you learned about t
difference between machine language and a programming language. You have
also learned how PL/SQL is different from SQL and about the PL/SQL basic block
structure. This is similar to learning the history behind a foreign language and in
what context it is used. To use the PL/SQL language, you have to learn the
keywords, what they mean, and when and how to use them. First, you will
encounter the different types of keywords and then their full syntax. Then you
will expand on simple block structure with an exploration of scope and nesting
blocks-This is about SQL, ORACLE, aspects of the book In the Introduction and Chapter 1, PL/SQL Concepts, you learned about t difference between machine language and a programming language.

Based on the present distributed power flow algorithms and the wind generator models, the paper designs a power flow calculation software, which includes a DG accessing module. This software has the function of generating IEEE example as well. By SQL structured language, the software can read and write efficiently between the backstage of example database and external files. The main establishment is "Power Flow Calculation Software" system, which has two versions: one is based on the ACCESS background database, and the other is based on the SQL Server backend database. Finally, with IEEE3-14, 30,39,43,57,118,145,162,300, total up to 16 examples, Newton power flow algorithm of the system was tested, whose results are consistent.

Description: 在众多的计算机应用中，有一类重要的计算机应用，称为数据密集型应用，例如，管理信息系统、办公信息系统、银行信息系统、民航定票系统、情报检索系统等，这是最大的计算机应用领域，管理这种大量的、持久的、共享的数据需要数据库技术。
JDBC是Sun提供的一套数据库编程接口，由Java语言编写的类、界面组成。用JDBC编写的程序能够自动地将SQL语句传送给相应的数据库管理系统，而且通过使用JDBC，开发人员可以很方便地将SQL语句传送给几乎任何一种数据库。也就是说，开发人员可以不必写一个程序访问Oracle，写另一个程序访问MySQL，再写一个程序访问SQL Server。
使用Java编写的应用程序可以在任何支持Java的平台上运行，Java和JDBC的结合可以让开发人员在开发数据库应用程序时真正实现“一次编写，处处运行！”。
-In many of the computer application, have a kind of important computer application, called data intensive applications, for example, the management information system, office information system, bank information system, civil aviation booking system, such as information retrieval system, this is the biggest computer application field, manage this a lot of, lasting, sharing of data to database technology.
JDBC is a set of Sun provide database programming interface, written by the Java language classes, interface component. Use JDBC programming can automatically will send it to the corresponding SQL database management system, and by using JDBC, developers can very conveniently the SQL statement sent to almost any kind of database. That is, the developers can don t need to write a program to visit Oracle, write another program access MySQL, to write a program to visit SQL Server.
Use Java write applications can be in any support Java on the platform of the operation, Java and JDB Platform: |
