根據日期從MySQL數據庫獲取數據

Question

我有一個名爲Order的表，由3列（id，date，price）組成。我試圖檢索date >= startdate AND date <= endDate的所有數據。列date的日期是在這種格式保存爲TEXT："MM-dd-yyyy HH:mm:ss"（10-27-2013 12:12:43）

我曾嘗試下面的SQL語句：

Cursor cursor = cr.query(PizzeriaContentProvider.CONTENT_URI_ORDER, null, PizzeriaDatabase.CELL_ORDER_DATE + " >= DATETIME ("+ startDate + ") AND " + 
       PizzeriaDatabase.CELL_ORDER_DATE + " <= DATETIME(" + endDate + ")", null, null); 

Cursor cursor = cr.query(PizzeriaContentProvider.CONTENT_URI_ORDER, null, PizzeriaDatabase.CELL_ORDER_DATE + " between (" + startDate + " AND " + endDate + ")", null, null); 

但他們都拋出同樣的異常：

java.lang.RuntimeException: Unable to start activity ComponentInfo{cz.vongrad.pizzeria/presentationLayer.ViewOrder}: 
android.database.sqlite.SQLiteException: near "14": syntax error: , 
while compiling: SELECT * FROM orders WHERE (date >= DATETIME(10-27-2013 14:01:53) AND date <= DATETIME(10-27-2013 14:01:53)) 

所以我想我比較錯誤的格式日期？

支持引號的缺失::

Cursor cursor = cr.query(PizzeriaContentProvider.CONTENT_URI_ORDER, null, PizzeriaDatabase.CELL_ORDER_DATE + " >= DATETIME ('"+ startDate + "') AND " + 
       PizzeriaDatabase.CELL_ORDER_DATE + " <= DATETIME('" + endDate + "')", null, null);
