MYSQL今天使用特定格式查询插入日期

Question

您好我想在今天使用特定日期格式的数据中插入数据。我在列中的日期设置为dd-mm-yyyy，但我想以28 October 2016

等文字格式插入日期

我知道今天如何插入当前日期，也知道如何选择具有特定格式的日期，但我对将这两个查询结合起来有点困惑

用于插入当前日期：

INSERT INTO product_table(product_names, product_type,product_brand,product_price,product_count,product_note, product_date) VALUES ('Logitech','Mouse','Sample',100,5,'1 year warranty',CURRENT_DATE)

用于选择具体日期格式

Select DATE_FORMAT(product_date, %d %M %Y) from product_table;

谢谢

如果您希望将日期作为FATAL EXCEPTION: main Process: com.example.awais_pc.contactapp, PID: 25641 java.lang.NullPointerException: Attempt to invoke interface method 'boolean android.database.Cursor.moveToNext()' on a null object reference at com.example.awais_pc.contactapp.AllContacts.onCreateView(AllContacts.java:43) at android.support.v4.app.Fragment.performCreateView(Fragment.java:1974) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1067) at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:1252) at android.support.v4.app.BackStackRecord.run(BackStackRecord.java:742) at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1617) at android.support.v4.app.FragmentManagerImpl.executePendingTransactions(FragmentManager.java:570) at android.support.v4.app.FragmentPagerAdapter.finishUpdate(FragmentPagerAdapter.java:141) at android.support.v4.view.ViewPager.populate(ViewPager.java:1177) at android.support.v4.view.ViewPager.populate(ViewPager.java:1025) at android.support.v4.view.ViewPager.onMeasure(ViewPager.java:1545) at android.view.View.measure(View.java:20151) at android.widget.RelativeLayout.measureChildHorizontal(RelativeLayout.java:716) at android.widget.RelativeLayout.onMeasure(RelativeLayout.java:462) at android.view.View.measure(View.java:20151) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:6328) at android.widget.FrameLayout.onMeasure(FrameLayout.java:194) at android.support.v7.widget.ContentFrameLayout.onMeasure(ContentFrameLayout.java:135) at android.view.View.measure(View.java:20151) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:6328) at android.support.v7.widget.ActionBarOverlayLayout.onMeasure(ActionBarOverlayLayout.java:391) at android.view.View.measure(View.java:20151) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:6328) at android.widget.FrameLayout.onMeasure(FrameLayout.java:194) at android.view.View.measure(View.java:20151) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:6328) at android.widget.LinearLayout.measureChildBeforeLayout(LinearLayout.java:1464) at android.widget.LinearLayout.measureVertical(LinearLayout.java:747) at android.widget.LinearLayout.onMeasure(LinearLayout.java:629) at android.view.View.measure(View.java:20151) at android.view.ViewGroup.measureChildWithMargins(ViewGroup.java:6328) at android.widget.FrameLayout.onMeasure(FrameLayout.java:194) at com.android.internal.policy.PhoneWindow$DecorView.onMeasure(PhoneWindow.java:3158) at android.view.View.measure(View.java:20151) at android.view.ViewRootImpl.performMeasure(ViewRootImpl.java:2594) at android.view.ViewRootImpl.measureHierarchy(ViewRootImpl.java:1549) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1841) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1437) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:7397) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:920) at android.view.Choreographer.doCallbacks(Choreographer.java:695) at android.view.Choreographer.doFrame(Choreographer.java:631) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:906) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:158) at android.app.ActivityThread.main(ActivityThread.java:7224) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1230) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1120) 存储在列中，则需要将其设为28 October 2016字段或其他内容。

如果是这样的话，我不想为什么要这样插入它，而不是仅仅在数据库出来的时候将其格式化？
