Collection size 1,321 exceeds maximum size of 1,000.

I looked at the other posts with a similar issue and didn't find what looked like my problem there. 

I have a user-driven SOQL query, and now that I've loaded a larger data set in the App (via dataloader.io, FYI) I'm seeing this problem whenever i run a query.

Help!

How to query detail records from SOQL

Hi.

I have a custom object (TargetX_SRMb__Application__c) It has a relationship to Contact defined in WSDL by:

  <complexType name="TargetX_SRMb__Application__c">
                <complexContent>
                    <extension base="ens:sObject">

...
                       <element name="TargetX_SRMb__Contact__c" nillable="true" minOccurs="0" type="tns:ID"/>
                        <element name="TargetX_SRMb__Contact__r" nillable="true" minOccurs="0" type="ens:Contact"/>

However, when I run SOQL test as:

 Contact contact = [SELECT  c.Id, c.lastName, (Select CreatedDate  FROM TargetX_SRMb__Contact__r) FROM Contact c]

I get error:

Error: Compile Error: Didn't understand relationship 'TargetX_SRMb__Contact__r' in FROM part of query call. If you are attempting to use a custom relationship, be sure to append the '__r' after the custom relationship name

I also tries adding a "s" as follows: Same error.

 Contact contact = [SELECT  c.Id, c.lastName, (Select CreatedDate  FROM TargetX_SRMb__Contacts__r) FROM Contact c]

 Is this not the correct syntax to query child records from a custom object?

Thanks in advance,

Jon
