tsql - Problems with update statement in c# -

-

im relatively new programming in c# , have come across problem during creating update statement, managed insert statement run there seems error confirmation of id, form looks database , displays information in datagridview, once record selected information displayed textboxes.

private void btnsave_click(object sender, eventargs e) {     dbcon.connectionstring = "provider=microsoft.ace.oledb.12.0; data source=elemental.accdb";       dbcon.open();      string sql = "update tblopencalls set [callid]= @callid, [staffid]= @staffid, [problemdesc] = @desc, [problemtype] = @problemtype, [department] = @department, [location] = @location, [urgency]= @urgency, [datecreated] = @created, [dateamend] = @amend, [allocatedto] = @allocate,  [forename] = @forename, [surname] = @surname [callid]= $callid";      oledbcommand cmd = new oledbcommand(sql, dbcon);       cmd.parameters.addwithvalue("@callid", txt_callid.text);     cmd.parameters.addwithvalue("@staffid", txt_staffid);     cmd.parameters.addwithvalue("@desc", txt_problemdesc);     cmd.parameters.addwithvalue("@problemtype", txt_problemtype);     cmd.parameters.addwithvalue("@department", txt_department);     cmd.parameters.addwithvalue("@location", txt_location);     cmd.parameters.addwithvalue("@urgency", txt_urgency);     cmd.parameters.addwithvalue("@created", txt_created);     cmd.parameters.addwithvalue("@amend", txt_amended);     cmd.parameters.addwithvalue("@allocate", txt_allocate);     cmd.parameters.addwithvalue("@forename", txt_forename);     cmd.parameters.addwithvalue("@surname", txt_surname);      cmd.executenonquery();     dbcon.close();     messagebox.show("field updated", "update"); }

the error have got syntax error in query expression '[callid]= $callid'. simple have missed out in advance advice.

you seem have typo;

where [callid]= $callid

should be

where [callid]= @callid
