Lookup condition

The lookup condition defines when the lookup returns values from the lookup object. When you configure the lookup condition, you compare the value of one or more fields from the data flow with values in the lookup object.
A lookup condition includes an incoming field from the data flow, a field from the lookup object, and an operator. For flat file and database connections, you can use the following operators in a lookup condition:
For other connections and for Lookup transformations that use a dynamic cache, you can use the = (Equal to) operator in a lookup condition.
