间歇性SQLiteException:在dbopen中没有错误 [英] Intermittent SQLiteException: not an error at dbopen

问题描述

在我的应用中，在很多情况下我都在使用数据库，但是在一种情况下，我遇到异常，而不是每次都可以并且可以重现它.

In my app I'm using DB in many situations, but there is one situation in which I'm getting an exception, not every time and could reproduce it (yet).

这仅在OS版本2.3.7和2.1-update-1上发生.

This is happening only on OS versions 2.3.7 and 2.1-update-1.

代码:

public void removeOldOccurrences() {
        SQLiteDatabase db = dbHelper.getWritableDatabase();
        Long oldTime = System.currentTimeMillis() - VALID_OCCURRENCE_TIME;
        String query = "";
        try {
            query = "DELETE FROM " + LOCATIONS_TABLE + " WHERE not ("
                    + REMEMBERED_FIELD + "=1) " + "and (" + LAST_FIELD + "<"
                    + oldTime + ");";
            db.execSQL(query);
        } catch (Exception e) {
            Log.e(TAG, query);
            e.printStackTrace();
        } finally {
            if (db != null) {
                db.close();
            }
        }
    }

异常跟踪为:

android.database.sqlite.SQLiteException: not an error
at android.database.sqlite.SQLiteDatabase.dbopen(Native Method)
at android.database.sqlite.SQLiteDatabase.(SQLiteDatabase.java:1849)
at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:820)
at android.database.sqlite.SQLiteDatabase.openOrCreateDatabase(SQLiteDatabase.java:854)
at android.database.sqlite.SQLiteDatabase.openOrCreateDatabase(SQLiteDatabase.java:847)
at android.app.ContextImpl.openOrCreateDatabase(ContextImpl.java:573)
at android.content.ContextWrapper.openOrCreateDatabase(ContextWrapper.java:203)
at android.database.sqlite.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:118)

请帮助.

推荐答案

在传递空字符串进行查询时，我也收到了同样的错误.

I have also received this same error when passing an empty string for query.
