Simple Condition Type

Simple Condition Type

Define a simple condition type for a sorted or unsorted Joiner transformation.
A simple condition includes one or more conditions that compare the specified master and detail sources. A simple condition must use the following format:
<master_port> operator <detail_port>
For a sorted Joiner transformation, the condition must use the equality operator.
For an unsorted Joiner transformation, the condition can use any of the following operators: =, !=, >, >=, <, <=.
For example, if two sources with tables called EMPLOYEE_AGE and EMPLOYEE_POSITION both contain employee ID numbers, the following condition matches rows with employees listed in both sources:
EMP_ID1 = EMP_ID2
The Developer tool validates datatypes in a simple condition. Both ports in the condition must have the same datatype. If you need to use two ports in the condition with non-matching datatypes, convert the datatypes so they match.
You can configure a list of join conditions in a simple condition. When you configure multiple join conditions, all the conditions must be true to make the join.
For example, you might configure the following statements in a simple condition:
StoreID = StoreNO Dept = Department Salary > Commission
If you view the same statements as an Advanced Condition, the join condition appears as the following expression:
StoreID = StoreNO AND Dept = Department AND (Salary > Commission)
