The select API is a powerful way for users to access the data offered to them through the Rich Data Services. The select API is based on a very familiar idea, users want to view their data in different ways. They may want to see all the data available or they may want to apply filters which allow them to see only specific records (rows) or variables (columns). While this functionality may seem similar to what a standard relational database can do, RDS takes it a step further by powering the selection capabilities with underlying metadata which allows for querying by Regular Expressions, and Keywords.
The select API will return to users the data that corresponds with their request. In addition to this each query returns a basic summary of the results, including the limits placed on the columns and rows, the offsets where the query started, and indicators as to whether there are more records/variables available.
Standard Select
The standard select query will show all variables and all records of a given data source to a point. The results will be limited by default to one hundred variables and one hundred records in order to preserve efficiency. The results can easily be paged using some convenience attributes.
