It is a logical operator that returns true if the left operand value is equal to some of the values enumerated in the right operand.
Att | Var | Property IN [(<comma-separated-constant-list>) | Collection | Array ]
Att IN Data Selector object
Where:
Collection refers to attributes or variables based on Collection Domains or variables defined as collection with the same data type of the left operand.
When the right operand is a list of constants delimited by comma, the IN operand is equivalent to the expression: LeftOperand = FirstConstant OR LeftOperand = SecondConstant ...
When the right operand is a Collection or Array, the semantic is the same, but the list varies depending on the elements the Collection or Array has in that specific execution.
In the case of In DataSelectors see Data Selectors in For Each command
- spc0075: Operand %1 does not match the data type of %2 in the IN comparison.
- spc0076: %1 must be a collection to be used as the right operand in an IN comparison.
- spc0077: %1's data type (%2) is not supported in an IN comparison.
Note: The IN with Collection or Array has not been rightly generated so far.
If &element in &Collection
...
EndIf
For Each
where Attribute in &Collection
...
EndFor
For Each
where Attribute in DataSelector
...
EndFor
Note that the first operand can only be an Attribute or Variable, not an expression (i.e "&numValue.ToString() IN &CharCollection " is not supported).
