The forum is currently being migrated to a new host. While the migration happens, the old server is still available. Once the new machine is ready, I will copy the database to the new machine. Feel free to ask and answer questions in the meantime.

I'm coming over from the MSSQL world and have gotten used to things like Skip to help with paging.

From what I can gather Skip isn't supported with the iSqlAnywhere provider so the only way I can think of off the top of my head are to use my filtered IQueryable to bring back primary keys and perform a skip take on them in memory and then do a contains to bring back the actual data I need.

To me this seems kind of hacky and I would definitely appreciate any other thoughts on the matter.

Writing SQL statements directly is not an option.

Here is an example of what I'd be doing.

IQueryable<foo> bar =  someAlreadyFilteredQueryable;
var barIds = bar.Select(b=>b.Id).ToList();
var finalIds = barIds.Skip(pageNum * pageSize).Take(pageSize);
var result =  someAlreadyFilteredQueryable.Where(s=> finalIds.Contains(s.Id)).ToList();

Like I said it seems hacky considering I can just do someAlreadyFilteredQueryable.Skip(pageNum * pageSize).Take(pageSize).ToList() with MSSQL.

Edit: It appears the query generated behind the scenes uses the ALL keyword that isn't supported in the version of sybase I'm hitting.

TLDR - You need to be on V12 to use Skip

Skip is supported. I use it in my code all the time.


For example, here's some code from my program that performs a paged search of one of the tables in our database:

noPages = (int) ( noMatchingEntries / pageSize );
if ( noMatchingEntries % pageSize != 0 )

if ( pageNo > 0 ) {
    query = query.Skip( pageNo * pageSize );

query = query.Take( pageSize );

Can you give me an example? What version are you running?

Every time I attempt to do so I get a syntax error - 'Syntax error near 'ALL' on line 6'

What SA version are you using?

We're using SA We're also using the same version of the SA ADO.NET / Entity Framework driver. See the edits to my answer for an example.
