About an Expression

An Expression is composed of operands and operators.

Operands

In Integration Studio, an operand is a Literal. A Literal is a constant and can be strings, numbers, boolean values, etc. There are some rules about strings that you must be aware of:

1. • Strings must be inside ". For example: "My string".

   • To add quotes " to your string, you must type double-quotes"" . For example, if the string you want to produce is xpto "123" xpto1, then you have to type the following:

"xpto ""123"" xpto1"

When editing the action parameters, entity attributes, or structure attributes you can use literals to define the default values.

Operators

The possible operators that can be used in an expression are:

• Numeric: Unary minus, arithmetic operators (+, -, / and *).

• Logical and Boolean: Unary Not, And, Or, Comparison operators (<, >, <=, >=), and equality operators (= and <>).
