    <p>I have a problem with my SQLite db. I store a new entry to the db with:</p> <pre><code>public Long createTest(String name, String lang) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_TEST_NAME, name); initialValues.put(KEY_TEST_LANGUAGE, lang); initialValues.put(KEY_TEST_TRIED, 0); initialValues.put(KEY_TEST_CORRECT, 0); return mDb.insert(DB_TABLE_TEST, null, initialValues); } </code></pre> <p>But when I try to get the new "test" from the db, I don't get anything..</p> <p>My debug code:</p> <pre><code>long id = mDbHelper.createTest(name, lang); if(id &gt; 0) mId = id; //A new id is returned!! Cursor testInfo = mDbHelper.getTestInfo(mId); startManagingCursor(testInfo); String lang_output = testInfo.getString(testInfo.getColumnIndexOrThrow(DbAdapter.KEY_TEST_LANGUAGE)); Log.i("AddTestDebug", "lang_output = " + lang_output); //lang_output is null </code></pre> <p><code>createTest()</code> returns a new id. But <code>lang_output</code> is <code>null</code>.</p> <p>The strange thing is that in my next activity, I call the exact same method (<code>getTestInfo(mId)</code>) and I get the <code>lang_output</code> to the correct value. I also get the correct value if I hardcode an earlier saved id. (<code>getTestInfo(26)</code>). The previous id is always working..</p> <p>My <code>getTestInfo</code> is</p> <pre><code>public Cursor getTestInfo(long id) throws SQLException { Cursor mCursor = mDb.rawQuery("SELECT test.name, test.lang, COUNT(words._id) AS num " + "FROM words, test " + "WHERE test._id = " + id + " " + "AND test._id = words.test_id", null); if(mCursor != null) { mCursor.moveToFirst(); } return mCursor; } </code></pre> <p>Why isn't the entry correctly returned the first time??</p>

    2. COIt's not two treads, but "sequentially" code... The actual code is in two different activites (the one with crateTest(..) is one activity, staring the next where I try getTestInfo. I put these together in the example above, and got the same problems..

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
