The incoming request has too many parameters. The server supports a maximum of 2100 parameters

Question

I have this seemingly simple linq-to-sql query that searches some data in several columns; something like this:

List TheTableIDs = list of IDs (s         


        

Answer 1

SQL doesn't support more than 2100 values in in statement, but you can use in with table with more than 2100 rows so you can insert your data into a table and change your query to check the in with selecting from that table

for example

Create TempIDs (bigint ID, uniqueidentifier guid)

guid column is for preventing mixing different user data

in your code

Guid myKey = Guid.New();
List TheTableIDs = list of IDs (sometimes more than 2100)
TheDataContext.TempIDs.InsertAllOnSubmit(TheTableIDs.select(i => new TempIDs{ID = i, Guid = mykey});
TheDataContext.SubmitChanges();

var QueryOutput = (from x in TheDataContext.SomeTable

                   where TheDataContext.TempIDs.Contains(x.ID) &&

                   x.Col1.Contains(SomeString) || 
                   x.Col2.Contains(SomeString))

                   select x.ID).ToList();

also if you can retrive the ids from database , you can write a table value function in sql to return the ids and model this function in your code, let say its name is fnGetIds. Then use it in your code as below

var QueryOutput = (from x in TheDataContext.SomeTable

                   where TheDataContext.fnGetIds().Contains(x.ID) &&

                   x.Col1.Contains(SomeString) || 
                   x.Col2.Contains(SomeString))

                   select x.ID).ToList();
