    <p>I am trying to get some data from a sqlite table named Course, with a attribute Name.</p> <p>I build the table here.</p> <pre><code>private static final String COURSE_ID = "CourseID"; private static final String COURSE_NAME = "Name"; private static final String COURSE_CODE = "CourseCode"; private static final String COURSE_ROWID = "_id"; private static final String COURSE_CREATE = "create table " + "Course" + " ( " + COURSE_ROWID + " integer primary key autoincrement, " + COURSE_ID + " integer not null," + COURSE_NAME + " text not null, " + COURSE_CODE + " text not null" + ");"; </code></pre> <p>I try to select my data with this function.</p> <pre><code> public Cursor getCourseNames() throws SQLException { String[] values = {COURSE_NAME}; mDb = mDbHelper.getReadableDatabase(); return mDb.query("Course",values, COURSE_ROWID + "=" + "Name", null, null, null, null, null); } </code></pre> <p>Then in my main class I execute it like this.</p> <pre><code> public void buildCoursetoChapterList(){ Cursor cursor = dbHelper.getCourseNames(); SimpleCursorAdapter adapter = new SimpleCursorAdapter(MainActivity.this, android.R.layout.simple_list_item_1, cursor, null, null); ListView listView = (ListView) findViewById(R.id.list); listView.setAdapter(adapter); } </code></pre> <p>I just want to grab the data and throw in in a list view, any idea what I am doing wrong? It seems like it is logical <code>Select from Course WHERE _id = "Name"</code>;</p> <p>Oh toot I forgot my error... java.lang.IllegalArgumentException: column '_id' does not exist</p>

Guidance
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).
