SPQuery and RowLimit

I have aro开发者_StackOverflowund 10000+ rows(Listitems) in a list I want to query.

I want to iterate each of the item in a timerJob - but I cant take all of them at a time since : Object Model Override - NO, ListView threshold - 1000 - in the FARM level and i we cant change this.

What is the way for me to iterate all the 10000+ (like a batch) ??

You should use a ContentIterator. This will allow you to iterate over the contents of very large lists without triggering an SPQueryThrottledException.

For example:

SPList list = SPContext.Current.Web.Lists["MyList"];

// Build query using an iterator-defined WHERE clause
string query = string.Format("<Where><Eq><FieldRef Name='MyFieldName'/><Value Type='Text'>MyFieldValue</Value></Eq></Where>{0}", ContentIterator.ItemEnumerationOrderByNVPField);

// Instantiate iterator and use it to process the list
ContentIterator iterator = new ContentIterator();
iterator.ProcessListItems(list, query, ProcessListItem, ProcessListItemError);

Then you'd define your ProcessListItem and ProcessListItemError thusly:

static void ProcessListItem(SPListItem item) {
    Console.WriteLine("ProcessListItem: Name {0}", item.Title);
}

static bool ProcessListItemError(SPListItem item, Exception e) {
    Console.WriteLine("ERROR: message {0}", e.Message);
    return true;
}

I'd also recommend you review Microsoft's Best Practices with SharePoint Server articles, in particular "Writing Efficient Code In SharePoint Server", which further discusses properly writing queries.
