1. 在IBConsole中添加两个用户LOGIN和MATER，密码均为PASSWORD。 2. 用MISDBA用户登录MISDB数据库。 3. 在ISQL中，输入第9章提供的SQL语句；或者根据表9-1至表9-8在SQL Explorer中自行创建数据表。数据库创建后需要分配LOGIN和MATER用户的访问权限。 4. 根据表9-9和表9-10设置初始数据，另外需要在PERSON数据表中设置一个用于登录系统的用户（ID=’MAT’，PASSWD=’PASSWORD’，AUTHORITY=’7’，STATE=’F’），同时在PART表中添加ID为’0000000000’的零件，名称为“。 5. 除了修改数据库连接的属性，还需要修改数据模块中LOGIN方法的相关用户密码。 -1. In addition two IBConsole users LOGIN and Mater. passwords are PASSWORD. 2. User login with MISDBA MISDB database. 3. In ISQL, the importation of Chapter 9 of SQL; Or, according to Table 9-1 to Table 9-8 in SQL Explorer to create data sheets. After creating the database needs and Mater distribution LOGIN user access permissions. 4. According to Table 9-9 and Table 9-10 initial data set, Another need PERSON data tables set up a registration system for users (ID = "MAT" PASSWD = "PASSWORD" AUTHORITY ="7 ", STATE = "F"), PART table at the same time adding ID to"0000000000 "parts, name. " 5. In add

重写了微软提供SQLHelper(共用的数据库调用接口） 1把SqlHelper的connectionString做成一个全局量，统一设置数据库连接字符串 2增加了返回特定表名的DataSet的各接口。 可在项目的config文件设置数据库连接字符串 private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"] 当然可以把数据库连接方法修改后直接用。-rewritten Microsoft SQLHelper (shared database Call Interface) a SqlHelper the connectionString caused an overall volume, uniform database connections increased by two strings to the specific name of the table in the DataSet interface. In the config files set database connection string private static string connectionString = System.Configuration.ConfigurationSettings.AppSettings [ "ConnectionString"] lt; !-- Application specific settings-- gt; Lt; AppSettingsgt; Lt; Add key
