Here is my piece of code which runs without errors, but doesn't update database:
ContentValues cv_lio = new ContentValues();
cv_lio.put("u_lio",1);
String where = "u_name" + "=" + 5;
db.update(table_name, cv_lio,where,null);
Can anyone improve my update query to work well.
Proceed as follow :
ReplyDeleteContentValues cv_lio = new ContentValues();
cv_lio.put("u_lio",1);
String where = "u_name" + " = ?";
String[] whereArgs = new String[] {String.valueOf(5)};
db.update(table_name, cv_lio, where, whereArgs);
please refer to documentation which is, I must confess, not so clear on that precise point...
