Server ESQ - Select records with list of ids

Hello community,


I have a case where I need to get details of records which match the list of Ids. Ie

select * from table where id in [list of ids];


How do I implement this using server esq?


The following 

  var fileIdFilter = fileLinkESQ.CreateFilterWithParameters(FilterComparisonType.Equal,

                    "UsrFileId", FileIds.ToArray()); //FileIds is a list of Guid

throws the error : System.FormatException: Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

Here is a sample scenario,

Step 1: Take the complete table into a collection

var entitySchemaManager = UserConnection.GetSchemaManager("EntitySchemaManager") as EntitySchemaManager;
var contactESQ = new EntitySchemaQuery(entitySchemaManager,"Contact");
contactESQ.JoinRightState = Core.DB.QueryJoinRightLevel.Disabled;
EntityCollection entities = contactESQ.GetEntityCollection(UserConnection);


Step 2: Parse through the collection via Linq


var count = (from elements in entities
             where elementsGetTypedColumValue<string>("FirstName") == "RequiredText"
             select elements).count();


Bhoobalan Palanivelu,

Thank you, but the table in question can hold 1000s of records at any given time. Bringing the whole table into memory and then performing LINQ may not be efficient. 

Also, I already know the list of records I need to fetch. Instead of

select * from table where id = A

select * from table where id = B

select * from table where id = C


I am looking for a query using "In" operator which will reduce the number of DB hits to 1 through

select * from table where id in (A,B,C).


This way I will have just the records I want to process in memory instead of whole table.
