database - Syntax error in INSERT STATEMENT from c# to Access DB - 


 con.open();         cmd = new oledbcommand("insert login (user, password) values ('" +textbox1 .text + "','" + textbox2 .text + "');",con);         cmd.commandtype = commandtype.text;         int temp = cmd.executenonquery();         if (temp > 0)         {            textbox1.text = null;             textbox2.text = null;             messagebox.show("record successfuly added");         }         else         {             messagebox.show("record fail added");         }         con.close();

when try insert of error appear ( syntax error in insert statement ) i'm try different method values parameters or direct plz !

  • escape reserved keyword user
  • use parameterized query
  • avoid sql injection
  • make use of disposable objects

try approach:

using (oledbconnection con = new oledbconnection(connectionstring)) {     con.open();     using (var cmd = new sqlcommand(     "insert login ([user], [password]) values (@user, @pass);",     con))     {         cmd.parameters.add(new oledbparameter("@user", textbox1.text ));         cmd.parameters.add(new oledbparameter("@pass", textbox1.text ));          if (temp > 0)         {             textbox1.text = string.empty;             textbox2.text = string.empty;             messagebox.show("record successfuly added");         }         else         {             messagebox.show("record fail added");         }     } }
