Sql – 樟少的博客

//编写了几个连接数据库的函数，由于是公共函数，可以独立编写在新的文件中，例如我自己建了一个StkFunction.h ,StkFunction.cpp上

Dbcnn

在CStkLibWnd 中增加了数据库相关的变量及初始化的函数，
BOOL m_IsSqlDBConnect; //是否已经连接Sql Db

_ConnectionPtr m_pCnn; //连接数据库

CSPString m_szConnString;//连接字符串

DBInitTable() ; //数据库初始化
CnnExecuteSql(CSPString sSql, bool nErr); //执行Sql命令

////////用于执行Sql命令

int CStkLibWnd::CnnExecuteSql(CSPString sSql, bool nErr)
{
_variant_t vntRecs[100];
long lRecs=1;
if(nErr)
{
try
{
m_pCnn->Execute(_bstr_t(sSql),
vntRecs,
adCmdText);
}
catch(_com_error e)
{
lRecs=0;
}
}
else
{
m_pCnn->Execute(_bstr_t(sSql),
vntRecs,
adCmdText);
}
return lRecs;
}

// DBInitTable() 只需要运行一次即可，把test()的改一下并运行一次就好。
