This refers to the code in Erist.protal.
Copy Code code as follows:

2004-2-2 Add an Introduction to the article Properties Jiangyong
OLECMD.PARAMETERS.ADD ("Articleintroduction", articleintroduction);
Perform
Erist.Common.Data.DataProvider.ExecNonQueryOle (Olecmd);
return ArticleID;
}
Notice that the background color is orange where the Erist.Common.Data.DataProvider.GetAutoID is called ()
The following is the code for this method
Copy Code code as follows:
/**////<summary>
Get Data Set
</summary>
<param name= "SQLCMD" > Execute command sqlcommand</param>
<returns> returns the obtained data set </returns>
public static DataSet Getdatasetole (OleDbCommand olecmd)
{
OleDbDataAdapter t_dataadapter;
DataSet t_dataset=new DataSet ();
Try
{
if (OleCmd.Connection.State!= ConnectionState.Open) OleCmd.Connection.Open ();
T_dataadapter = new OleDbDataAdapter (olecmd);
T_dataadapter.fill (T_dataset);
return t_dataset;
}
catch (Exception ex)
Captures the data-tier error and returns it to the previous layer.
{
Throw ex;
}
Finally
{
Break link
if (OleCmd.Connection.State = = ConnectionState.Open) OleCmd.Connection.Close ();
}
}
/**////<summary>
Get the maximum field value for a table
</summary>
<param name= "FieldName" ></param>
<param name= "tablename" ></param>
<returns></returns>
public static int Getautoid (string FieldName, String tablename,string connectstring)
{
DataSet ds;
OleDbConnection olecon=new OleDbConnection (ConnectString);
OleDbCommand olecmd=new OleDbCommand ();
olecmd.commandtext= "Select Max (" + FieldName + ") as Maxid from" + tablename;
Olecmd.commandtype=system.data.commandtype.text;
Olecmd.connection=olecon;
Ds=getdatasetole (Olecmd);
if (ds. Tables[0]. Rows[0][0] = = DBNull.Value)
{
return 1;
}
Else
{
return int. Parse (ds. Tables[0]. Rows[0][0]. ToString ()) + 1;
}
}
According to the FieldName and TableName to read the database the current largest fieldname if not returned 1
On the basis of this +1 because you want to get the only fieldname to add a record
Here fieldname is ArticleID
This method is still good.
