Question

Is there an equivalent of right() function that I can use in jquery. I want to get records with fileextension xlsx.

 new Guid(context.Documents.Where(T => T.FileName == ".xlsx").Select(T => T.ItemGuid).First().ToString());

something like

 select * from document where right(filename,4) = 'xlsx'

I don’t want to store the filename in a variable and later manipulate it. I want to be able to directly use it in my where condition. ‘Documents’ is my table name and “FileName” is a field that holds names of the file that I upload, now I need to get filter only the files that has the extension ‘xlsx’. I tried doing

  guid temp = new Guid(context.Documents.Where(T => T.FileName.Substring(T.FileName.Length - 4) == ".xlsm").Select(T => T.ItemGuid).First().ToString());

but I get the error “Sequence contains no elements” error.

* Update: Used the EndsWith() to get the information I wanted. This works now:

  guid temp = new Guid(context.Documents.Where(T => T.FileName.EndsWith("xlsm")).Select(T => T.ItemGuid).First().ToString());

thanks.

Answer 1

right() is the same as endswith()

function endsWith(str, suffix) {
    return str.indexOf(suffix, str.length - suffix.length) !== -1;
}
