我有两个独立的数据库,我想从中检索数据并在一个网格视图中显示。我遇到的困难是我只有一个数据库中的表中有一个产品密钥,并且与另一个数据库中的实际产品产品相同的产品密钥集,现在我想在一个网格视图中显示产品数据.. ..如果这是有道理的。
我该如何做到这一点,合并数据并将产品数据再次显示在一个网格中的键上。
string connString = "Data Source=.\\SQLEXPRESS;Initial Catalog=LRVWebsite;user ID=sa;password=lrmg;";
SqlConnection sqlCon;
OleDbConnection conn;
DataSet setOleDb;
DataSet dsSql;
private void bindData()
{
try
{
conn = new OleDbConnection(@"Provider=Microsoft.Jet.OleDb.4.0;
Data Source =" + Server.MapPath("App_Data\\LR Product Database 2000.mdb"));
conn.Open();
setOleDb = new DataSet();
OleDbDataAdapter dbaOle = new OleDbDataAdapter("SELECT * FROM tblProducts", conn);
dbaOle.Fill(setOleDb);
sqlCon = new SqlConnection(ConfigurationManager.ConnectionStrings["LRVWebsite"].ToString());
sqlCon.Open();
dsSql = new DataSet();
SqlDataAdapter dba = new SqlDataAdapter(@"SELECT C.CustomerFirstName,C.CustomerLastName, C.CustomerCompany,C.CustomerPosition,C.CustomerCountry,C.CustomerProvince,C.CustomerContact,CP.ActionDate,CP.ProductCode,CP.CustomerEmail FROM tblCustomers C INNER JOIN tblCustomerProducts CP ON C.CustomerEmail = CP.CustomerEmail ORDER BY ActionDate DESC", connString);
//@"SELECT C.CustomerFirstName,C.CustomerLastName,C.CustomerCompany,C.CustomerPosition,C.CustomerCountry,C.CustomerProvince,C.CustomerContact,CP.ActionDate,CP.ProductCode,CP.CustomerEmail FROM tblCustomers C INNER JOIN tblCustomerProducts CP ON C.CustomerEmail = CP.CustomerEmail ORDER BY ActionDate DESC", connString);
dba.Fill(dsSql);
dsSql.Merge(setOleDb);
GridView1.DataSource = dsSql;
GridView1.DataBind();
sqlCon.Close();
这是我尝试过的。现在,我怎样才能让产品密钥与包含相同产品密钥的另一个表中的实际产品相关联?
