Question

I am working in an android application and I want to work fetch details in my application local Db. The query that I am using has inner join,so its not returning values.But in the same method if I use with the query without inner join it returns value.
Please help me

public boolean isAvailableTransitionFile(String MenuName) {

    String query = "select * from Transition_File_Table inner join item_sync on Transition_File_Table.Menuitem_id=item_sync.id where item_sync.itemName=?";
    Cursor cursor = this.db.rawQuery(query,
            new String[] { String.valueOf(MenuName) });
    Log.e("Count", cursor.getCount() + "");
    if (cursor.moveToFirst()) {
        return true;
    } else {
        return false;
    }
}

SQL problems are usually due to a wrong syntax utilization in SQL, always test them before you use them in a program. I found a similar post here:

How do I join two SQLite tables in my Android application?

And you should try this code:

String query = "select * from Transition_File_Table TF inner join item_sync IS on
TF.Menuitem_id=IS.id where IS.itemName=?";

Cursor cursor = this.db.rawQuery(query,new String[]{String.valueOf(MenuName)});
