Hi All,
In interviews i have always been asked the question that what is difference between using query expression and fetch xml.
can anybody tell me what should be my answer in this case.in terms of retriving rcord limit,accessing related intity colums, paging , using link entities with query expression . how can i answer because some where i got confuse .
so can anybody give me proper answer for this.
Thanks in advance.
Hi Mona,
In summary:
If you need aggregation or grouping you must use fetchxml;
if you need to add Criteria conditions dynamically in the code it's easier with QueryExpression, but fetchxml is still an option.
