Remarques

There are two kinds of filters in the Business Data Catalog:

User Input filters
System filters
User Input filters require users to provide filter values such as the Comparison, Limit and the Wildcard filters.
System filters are system-provided. Following are the User Input filters that Business Data Catalog supports:
Limit filter Limits the number of instances returned to n. SQL supports this filter with the SELECT TOP clause. By using a Limit filter, you can prevent long waits, time outs, and users from issuing bad queries that request large amounts of data.
Comparison filter Takes an operator and a condition and returns only the instances that meet the condition.
Wildcard filter Limits the instances returned to those where field like value, where value may contain the asterisk (*) wildcard character. Users can use this filter type to present more user-friendly filters such as "starts with" and "contains".
