我用下面方法添加了Mta表很成功,但添加多个表时就不行了,请提示一下!

_bstr_t strConn="Provider=SQLOLEDB;Password=;User ID=sa;Data Source=";
  CString strCreateTable("USE master 
CREATE TABLE dbo.Mta (
mtaName varchar (50) ,
dataName varchar (50)  COLLATE Chinese_PRC_CI_AS NULL))");
try
{
m_pConnection.CreateInstance(__uuidof(Connection));
m_pConnection->Open(strConn,"","",adModeUnknown);
m_pConnection->Execute(_bstr_t((LPCTSTR)strCreateTable),NULL,adExecuteNoRecords);
}
