[Rets-dev] Problem with Importing Rets (MRMLS) listings

[Paul Stusiak]

Most systems do not permit unqualified queries - large row sets. Some 
vendors have implemented the optional RETS parameters of offset while 
others have different methods for pulling such data. Some do not allow 
such types of queries, either for technical reasons or for policy 
reasons. Some systems will deny access to connections that do "nasty" 
requests, those requests that make an unreasonable demand on the system 
or limit such queries to a specific time window.

You should contact MRMLS to determine what is permitted and how they 
suggest formulating the query for optimum accuracy and performance. I 
suspect that they will provide you with a technique to walk the results 
through multiple requests. On some systems, if it were permitted, your 
request may result in more than 500,000 rows.

In any case, you should be seeing the <MAXROWS/> tag if you have 
additional records that can't be sent. You didn't say that you were 
getting a 20208 response.

Again, I believe that you need to contact the MLS directly.
