android.database.sqlite.SQLiteException: near ";": syntax error (code 1):

I am getting this error when I am trying to delete a record from the database. Here is the error in full

Process: itp231.dba.nyp.com.bloommain, PID: 12274

Looking at the log, it directed me to this line of codes (my deleteRecord() method -

private void deleteRecord() {
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setMessage("Are you sure you want delete this person?");

new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
String id = editTextId.getText().toString().trim();

String sql = "DELETE FROM events WHERE id= " + id + ";";
Toast.makeText(getApplicationContext(), "Record Deleted", Toast.LENGTH_LONG).show();
c = db.rawQuery(SELECT_SQL,null);


1 - Your id is a blank string, therefore it can't be parsed in your SQL command.
2 - If your id field is a TEXT (???), then you need to enclose it in single quotes.
3 - For SQL commands, use execSQL() instead of rawQuery() - rawQuery() only works on... queries (SELECT)
4 - And... prepared statements (or bound parameters) are a better choice. The placeholders (?) will be replaced automatically in their positional order and the quotes won't be a problem anymore (Android will handle that for you!).
