                        PowerBuilder8.0动态连接SQL Server技巧

        我们都知道，一般情况下PB是和数据库结合最紧密的。那么，要掌握PB和数据库的连接是很重要的。因为数据库连接作为前后台关联的桥梁。下面我就将PowerBuilder8.03和Ms SQL Server2000的动态连接写出来和大家分享：

      首先，创建一个connect.ini文件，其内容为：                                                        [Database]
DBMS=MSSQL SQL Server 2000
Database=erp  
UserId=sa  
DatabasePassword=
LogId=sa
LogPassword=
ServerName=family
DbParm=
Lock=
Prompt=0          

其中：erp指您要连接的数据库名称；SA是数据库连接ID，Family是指您要连接的数据库的计算机名称，也可以用IP地址来代替。接下来，我们就在系统应用的Open事件中进行编码：                                                                                                                    string ls_inifile ="connect.ini"       

//进行数据库连接------------------------------------------------
SQLca.DBMS      = ProfileString ("dbconnect.INI", "database", "dbms",       "")
SQLca.database  = ProfileString ("dbconnect.INI", "database", "database",   "")
SQLca.logid     = ProfileString ("dbconnect.INI", "database", "logid",      "")
SQLca.logpass   = ProfileString ("dbconnect.INI", "database", "LogPassWord","")
SQLca.Servername=ProfileString("dbconnect.INI","database", "Servername",    "")
SQLca.dbparm    = ProfileString ("dbconnect.INI", "database", "dbparm",     "")
SQLca.autocommit=true;

connect using SQLca

If SQLca.SQLcode<>0 then  

    Messagebox（"错误","不能连接到数据库！请检查数据库连接或者ini配置"）

else

end if

      至此， PowerBuilder8.0动态连接SQL Server技巧基本上介绍完毕。写该文章的目的就是和大家进行交流。
