How to fetch random record from catalog table?
In MsSql, I can do this with a query. How can I do it in 1C?
Example: There are 500 records in the catalog table. I want to list 15 of them randomly. How can I do that?

Try to access your query results through Get(Index) method in which instead of Index use generated random number in the range from 0 to number of records in the query results.
