Question

我有一个名为Order的表，包含3列（id，date，price）。我正在尝试检索date >= startdate AND date <= endDate的所有数据。 date列中的日期格式保存为TEXT："MM-dd-yyyy HH:mm:ss"（10-27-2013 12:12:43）

我尝试了以下SQL语句：

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);

但是他们都抛出了同样的例外：

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))

所以我想我用错误的格式比较日期？

失踪的COMMA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);

根据日期从MySQL数据库获取数据
