[Enhancement] Configurable Custom SQL Row limit [Section in BizTalk360] Custom SQL Queries (backend changes in the database) [Comments/Fix Provided] 
The custom SQL Row limit was previously hard coded to 50. That means, you will be able to see only a maximum of 50 records in the page. In the current release, this value is configurable in the database. (Setting the value of CUSTOM_SQL_MAX_ROW_COUNT). If there is no value entered for CUSTOM_SQL_MAX_ROW_COUNT, then it defaults to 300.
