Two-Integer Variable Example
This example includes two Integer variables in a workflow (VarInt1=20 , VarInt2=3). The following options to use JUEL expressions are used in a workflow node node parameters:
- "${VarInt1} + ${VarInt2}" returns the string "20 + 3"
${VarInt1} and ${VarInt2} are replaced with actual workflow variable values but NO arithmetic calculation is completed. The result is a string with replaced values.
- "${VarInt1 + VarInt2}" returns calculated value "23"
The variables resolve to values and calculation on values is completed. The result is the calculated value.
The following can be used in applicable node parameters based on business needs for the corresponding workflow node:
- The JUEL expression that returns a string with the replaced workflow variables.
- The JUEL expression that returns a calculated value.
The input parameter in Stored Procedure or Macro nodes requires a calculated value. This means a JUEL expression in a Formula input parameter must return a value such as "${VarInt1 + VarInt2}" (returns the calculated value of "23").
