테이블의 id로 삭제를 하려고 아래와 같이 코드를 작성했습니다. 그런데 에러가 뜨네요
id는 integer형식이고 primary key, autoincrement입니다.
Button delete = (Button)findViewById(R.id.delete_button);
EditText delete_text =(EditText)findViewById(R.id.delete_text);
str_delete = delete_text.getText().toString();
dbmanager = new DBManager(this);
sqlitedb = dbmanager.getWritableDatabase();
delete.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
String sql = "delete from customers where id = "+str_delete+";";
sqlitedb.execSQL(sql);
sqlitedb.close();
}
});
