Comparison expressions
You can use the following operators in comparison expressions:
- = or == for "equal to"
- != for "not equal to"
- < for "less than"
- <= for "less than or equal to"
- > for "greater than"
- >= for "greater than or equal to"
Strings and bytes can be converted to numeric types when they are compared to numeric types. For example, in "1" < 2, "1" is converted to an integer to perform the comparison. If the string cannot be converted to a numeric type, an exception is raised.
If one of the values is missing, the expression returns an exception, except in Talend Cloud Pipeline Designer and Talend Data Mapper where it returns false.
If you compare a Boolean to a string, the string "true", regardless of its case, is interpreted as true, and other strings are interpreted as false.
The following examples are valid comparison expressions that return
true:
2 < "3"
"200" >= 100
2 == "2"
"true" == true
0x0A == 10
"5e+2" == 500
