Retrieve the members of a specific Team
The code to retrieve the members of a specific Team is quite easy, it's a standard QueryExpression, but contains a linked entity with a condition inside, it's good as start point for similar queries.
Hii, i still didte get it on this line:
ReplyDeleteLinkEntity teamLink = new LinkEntity("systemuser", "teammembership", "systemuserid", "systemuserid", JoinOperator.Inner);
there is linkfromattribute and linktoattribute which has same value. When i use custom entity, and i want to do sql query like this:
SELECT user.name, order.id from order inner join on user.id = order.id
so in the linkentities i can write like :
LinkEntity link= new LinkEntity("user", "order", "user.id", "order.id", JoinOperator.Inner);
What if we dont even know which field on the custom entity is the primary key. How do we know the primary key of the entity?
Actually this i posted my problem on community.microsoft forum, but i had't get the answer

don't try to convert queries from SQL to QueryExpression, you start from the query you want to have and build the QueryExpression. In this particular case we have the standard N:N relationship "teammembership" that because is a standard N:N it contains the primary keys of both entities involved, teamid and systemuserid, so we link the systemuser table and teammembership table using systemuserid in both table (and put the condition to teamid on the linkcriteria that belongs to the teammembership entity
