    text
    copied!<p>I've a code that display a list of items based on a custom adapter. To display a content of a table no problem but when I need to add a reference to many table it's another thing. Two solution are possible in my point of view:</p> <p>1) Querying the database inside setViewValue (didn't investigate too much this possibility) or 2) Find a way to associate dynamically a column to my other tables</p> <p>(solution for both are welcome) </p> <p>I have a main table where a column called slug is a reference to other tables. These other tables contain some data which I would like to count.</p> <p>Once I have my query I use a SimpleCursorAdapter to display a nice list in android (eg 1024 (2 ref), 2048 (3 ref)...).</p> <p>I think a little schema is probably better than my explanation.</p> <pre><code>Table: A ----------------------- _id | slug | value | ----------------------- 1 | a_a | 1024 | 2 | g_z | 2048 | ----------------------- Table: mytable_a_a ---------------- _id | value | ---------------- 1 | xxx | 2 | yyy | ---------------- Table: mytable_g_z ---------------- _id | value | ---------------- 1 | xxx | 2 | yyy | 3 | zzz | ---------------- The goal is to produce something like ------------------------------- _id | slug | value | count ------------------------------- 1 | a_a | 1024 | 2 2 | g_z | 2048 | 3 ... </code></pre> <p>I've tried something like:</p> <p>SELECT * FROM A UNION SELECT COUNT(*) FROM A.slug;</p> <p>but I'm missing the point and if a solution exists it would be a bit more complicated.</p> <p><em>possible workaround: include a counter in the table a</em></p> <p>Thank you</p>
