Constructing Filter Strings
When constructing a filter string, keep these rules in mind:
- Use the logical operators defined by the OData Protocol Specification to compare a property to a value. Note that it is not possible to compare a property to a dynamic value; one side of the expression must be a constant.
- The property name, operator, and constant value must be separated by URL-encoded spaces. A space is URL-encoded as
%20
. - All parts of the filter string are case-sensitive.
- The constant value must be of the same data type as the property in order for the filter to return valid results. For more information about supported property types, see Understanding the Table Service Data Model.
