> Key: IGNITE-7889
> URL: https://issues.apache.org/jira/browse/IGNITE-7889
> Project: Ignite
> Issue Type: Bug
> Components: platforms
> Affects Versions: 2.1
> Reporter: Alexey Popov
> Assignee: Alexey Popov
> Priority: Major
> Labels: .NET

> The following code completely ignores the Where condition:
> {noformat}
> var groupByQuery2 = models.Where(m => m.Value.DateTicks < 10 && m.Value.Dirty.HasValue).GroupBy(m => m.Value.ContractId)
> .Select(g => new KeyValuePair<string, int>(g.Key, g.Select(m => m.Value.Version).Min()));
> {noformat}
> debugger shows SQL without WHERE:
> {{CacheQueryable [CacheName=someCache, TableName=MODEL, Query=SqlFieldsQuery [Sql=select _T0.CONTRACTID, min (_T0.VERSION) from "someCache".MODEL as _T0 group by (_T0.CONTRACTID), Arguments=[], Local=False, PageSize=1024, EnableDistributedJoins=False, EnforceJoinOrder=False, Timeout=00:00:00, ReplicatedOnly=False, Colocated=False, Schema=, Lazy=False]]}}
