Sergey Stronchinskiy commented on IGNITE-4636:
----------------------------------------------
[~ptupitsyn],
While working on this feature found that {{SqlFieldsQuery}} fails if it is
passed collection of {{int}}'s instead of {{objects}}:
{code}
employeeCache.QueryFields(new SqlFieldsQuery("select p.name, p.salary from
Employee p join table(id bigint = ?) i on p.organizationid = i.id"
, new object[] { new [] { 1, 3 } }));
{code}
> .NET: Support local collection joins in LINQ
> --------------------------------------------
>
> Key: IGNITE-4636
> URL: https://issues.apache.org/jira/browse/IGNITE-4636
> Project: Ignite
> Issue Type: Improvement
> Components: platforms
> Affects Versions: 1.8
> Reporter: Pavel Tupitsyn
> Assignee: Sergey Stronchinskiy
> Labels: .NET, LINQ
> Fix For: 2.1
>
>
> LINQ {{IN}} clause is implemented in IGNITE-4425 and maps from
> {{ICollection.Contains}}.
> However, {{IN}} has some limitations in Ignite, and better alternative is
> temporary table join:
> https://apacheignite.readme.io/docs/sql-performance-and-debugging#sql-performance-and-usability-considerations
> Example SQL:
> {code}
> new SqlFieldsQuery("select p.name from Person p join table(id bigint = ?) i
> on p.OrgId = i.id", new object[] { new object[] {1,3}})
> {code}
> Add support in LINQ like this:
> {code}persons.AsCacheQueryable().Join(new[] {1, 3}, p => p.Value.OrgId, x =>
> x, (p, x) => p);{code}
