asp.net - Local sequence cannot be used in LINQ to SQL implementations -


so here trying do. have tables db , 1 list of member. member asp.net membership controls , combined membership , profile object. have function return list following mems object:

public property firstname string = "" public property lastname string = "" public property address1 string = "" public property address2 string = "" public property city string = "" public property state system.int32 = "0" public property zip string = "" public property title string = "" public property phone system.decimal = "0" public property id system.int32 = "0" public property usertype system.int32 = "0" public property ssn system.int32 = "0" public property email string = "" public property username string = "" public property islockedout boolean = false private loaded boolean = false

then have 2 tables of jobs , accounts:

jobs

jobid   numeric(18,0) accountid   numeric(18,0) name    varchar(50) frequency   int modifier    varchar(90) active  bit sdate   date edate   date

accounts

accountid   numeric(18,0) companyid   numeric(18,0) contactid   varchar(256) type    int name    varchar(256) address1    varchar(50) address2    varchar(50) city    varchar(50) state   int zip varchar(5) authcode    varchar(10) comments    text

the output trying achieve list of jobs accounts particular companyid info mems. have working elsewhere accounts, when throw jobs in mix, give me error of:

local sequence cannot used in linq sql implementations of query operators except contains operator.

here have gotten function of moment:

    <system.web.services.webmethod(enablesession:=true)> _ public shared function jobsearch(json string) string     dim damnser new javascriptserializer     dim search searchstring = damnser.deserialize(of searchstring)(json)     dim mydb new mydbdatacontext     dim pro new mems(httpcontext.current.user.identity.name)        dim acc = in mydb.accounts a.companyid = pro.id select      dim acclist = acc.where(function(r) r.accountid).[select](function(r) r.accountid.tostring()).toarray()      dim q = u in util.getmems join in acc on a.contactid equals u.username             u.firstname.tolower.contains(search.firstname.tolower) ,             u.lastname.tolower.contains(search.lastname.tolower) ,             a.name.tolower.contains(search.name.tolower) ,             a.contactid.tolower.contains(search.email.tolower) ,             u.phone.tostring.contains(search.phone.tolower) ,             a.accountid.tostring.contains(search.accountid.tolower)             select new {.firstname = u.firstname,                                       .lastname = u.lastname,                                       .name = a.name,                                       .email = u.email,                                       .phone = u.phone,                                       .accountid = a.accountid,                                       .city = a.city,                                       .state = (from s in mydb.states s.stateid = a.state select s.stateabbr).single                             }     'this line added between have working , new section , error happens     dim qq = j in mydb.jobs acclist.contains(j.accountid) select new {j.jobid, j.name, (from z in q z.accountid = j.accountid).single}      return damnser.serialize(qq) end function

i decided go different route it
