OleDbDataAdapter UPDATE statement prompts INSERT INTO syntax error resolution

1. Use OleDbDataAdapter to update data to data in other tables based on the SELECT statement, as follows: public static bool Datasetupdatetable (String Selectsql,dataset ds) {T ry{
Oledbconnertion connection=new OleDbConnection ("link string"); connection.     Open ();     DataSet dsnew=new DataSet ();     OleDbDataAdapter adapter=new OleDbDataAdapter ("Selectsql", connection);      OleDbCommandBuilder ocb=new OleDbCommandBuilder (adapter); Ocb. Quoteprefix= "[";//This is to exclude the prompt "INSERT INTO syntax error" OCB when the update command is executed.     Quotesuffix= "]"; Adapter.     Fill (Dsnew, "DS"); object[] Obj=new object[ds. Tables[0].     Columns.count]; foreach (DataRow Dr in DS. Tables[0]. Rows) {Dr. Itemarray.copyto (obj,0);
Danew.tables[0]. Rows.Add (obj);
int Count=adapter. Update (Dsnew, "DS");
Dsnew.acceptchanges (); }
catch (System.Data.OleDb.OleDbException ex) {//exception handling
return false;
return true; 2, the implementation of the Update method prompts "insert INTO syntax error" to add the method of winning the red two words, namely OCB.     Quoteprefix= "["; Ocb. Quotesuffix= "]";
