Dynamics CRM Odata 查询过滤器按选项集值

Question

How do I filter records by optionset value? I am trying like this:

 "$select=new_id&$filter=new_campaignid/Id eq guid'" + myId+ "' and new_optionsetfield eq '" + optionsetCode + "'"

But this does not work. I keep on getting bad request with error message:

Operator 'eq' incompatible with operand types 
'Microsoft.Crm.Metadata.ComplexTypeInstance`1[[Microsoft.Xrm.Sdk.OptionSetValue, Microsoft.Xrm.Sdk, Version=8.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]' 
and 'System.String' at position 96.

Answer 1

I'm pretty sure this is what you need:

"$select=new_id&$filter=new_campaignid/Id eq guid'" + myId+ "' and new_optionsetfield/Value eq " + optionsetCode

Edited: Removed the quotes, because that is an int value, not a string

Here's an exact working sample:

AccountSet?$filter=CustomerTypeCode/Value eq 1

我的 Dynamics CRM 365（内部部署）过滤器之一如下所示

var filter = "(substringof('SomeStringValue', Description) eq false) and (StatusCode/Value ne 1)";
