    <p>I'm extending the SQLiteOpenHelper class to help me connect and do my database work. According to the <a href="http://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html" rel="nofollow" title="docs">documentation</a>, the OnCreate method should only be called if the database has not been created. Yet, my problem is that I am getting this error when I try to execute a query to insert a record.</p> <pre><code>ERROR/Database(214): Failure 1 (table Sample already exists) on 0x218688 when preparing 'CREATE TABLE Sample (RecId INT, SampleDesc TEXT);'. </code></pre> <p>The only place this Create query is used in code is the OnCreate method which looks like this.</p> <pre><code> @Override public void onCreate(SQLiteDatabase db) { db.execSQL(SAMPLE_TABLE_CREATE); } </code></pre> <p><strong>Note:</strong> I'm following a <a href="http://www.screaming-penguin.com/node/7742" rel="nofollow" title="Here">tutorial</a> - the only thing I've done different is make the SQLiteDatabase object public instead of private so that I could extend this class for each entity, letting the public SQLiteDatabase object from the inherited DataHelper class do all the work</p> <p>Here is the method that makes the call that fails.</p> <pre><code> //This method is in the class that extends DataHelper (See note on tutorial) public void createSample(Sample sample)//next action form { String id = sample.getId(); String name = sample.getSummary(); String query = "INSERT INTO " + SAMPLE_TABLE_NAME + "( " + SAMPLE_Id + "," + SAMPLE_NAME + ") " + " VALUES (" + id + "," + name + ")"; try{ data.rawQuery(query, null); } catch(SQLException e){ Log.i("Sample", "Errors: Sample LN60: " + e.getMessage()); } } </code></pre> <p>Can someone tell me what I'm doing wrong? Or maybe a hack (i.e. check if table exists before executing create statement)</p> <p>Please let me know what other code I can post to solve this...</p>

    1. COIt's strange, in my app it works Ok right out of the box (I don't need to manually check if the DB has been already created, because onCreate() is only called if the DB has not been created yet). Probably post all of your DB related code?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
