Manipulate Data in the Cloud: ADO.NET Data Services Framework Arithmetic, Logical, and Grouping Filters: Table 2: Apply Arithmetic, Logical, and Grouping Operators as URI Filters.
URI filters correspond to restructured SQL WHERE clauses or LINQ Where query operators. Abbreviations replace arithmetic and logical symbols, which aren't valid in URIs. Use logical or and and operators for compound filters, and apply precedence grouping operators to segment operations. The .../ abbreviation represents the service prefix, such as http://localhost:52660/Northwind.svc/. Italic text is part of the URI query.
