mysql数据库访问次数的限制问题？
各位老师：我在wxwidgets下对数据库进行写入操作，当我调用这个函数的时候，插入数据次数只能插入100次就弹出：不能建立连接 对话框，请问这个是什么原因？请老师指点，谢谢。
void DataBaseDialog::InsertDataBase( wxCommandEvent& event )
{
wxDbConnectInf *DbConnectInf = NULL; // 定义数据库连接信息指针DB connection information
wxDb *Conn = NULL; // 定义数据库连接指针Database connection
wxDbTable *table = NULL; // 定义数据表指针Data table to mysql

  DbConnectInf = new wxDbConnectInf(0, wxT(""), wxT(""), wxT(""));//这里定义的内容基本没用，但不定义会报错

Conn = new wxDb(DbConnectInf->GetHenv());

bool DBfailOnDataTypeUnsupported=!true;//

if(!Conn->Open(wxT("driver={mysql odbc 5.1 driver};server=192.168.100.13;DSN=icdata_db;charset=gb2312;database=icdata_db;uid=root;pwd=duangexin;port=3306;"),DBfailOnDataTypeUnsupported))//使用驱动程序的方式打开数据库
{
wxMessageBox("不能建立连接","DB CONNECTION ERROR", wxOK | wxICON_EXCLAMATION);
}

table = new wxDbTable(Conn, wxT("ictable"),10,wxT(""),!wxDB_QUERY_ONLY, wxT(""));

//定义保存列内容的变量
wxString sst;

//打开DbTable对象
if( !table->Open())
{
wxMessageBox("不能打开数据库结构表!");
return;
}

//获取当天操作时间
wxDateTime now = wxDateTime::Now();
wxString strDate = now.Format(wxT("%Y-%m-%d"));

// //添加新记录
  wxStrcpy(ChipNumbers, wxT("2323")); //ChipNumbers所绑定的字段将添加一条记录

if(!table->Insert())

{

//判断添加是否成功
wxMessageBox("添加失败!");
return;

}

//提交更新数据库

table->GetDb()->CommitTrans();
