General operators

Description of general operators used in decision tables

List of general operators

Every condition cell in the decision table can have a different operator. These are the general operators which you can choose from:
All the input values (left operands) are auto-casted (meaning the value will be converted to the data type needed by the operator, whenever possible).
ALL THE RIGHT SIDE OPERANDS ARE ALSO AUTOCASTED.
THUS NO QUOTEMARKS SHOULD BE USED IN THE TABLE VALUES.
We use the double quote marks in the table values only to highlight the fact that these will be converted to string on the backend.

Anything Operator (anything)

The anything operator (anything) returns true always.

Equals Operator (=)

Compares two scalar values. The equal operator compares mainly:
  • String
  • Number
  • Boolean

Equal Operator examples:

[request value] = [table value]
3 = 3 //true
"3" = 3 //true
true = true //true
"true" = true //true

IS IN Operator (IN)

The IS IN operator ( in ) returns true if the right operand contains the left operand, and false otherwise.
  • Members of the set can be separated by pipe (|), comma (,), semicolon (;)
  • The right operand has to be an array []
  • Only exact matches!

IS IN Operator examples:

[request value] IN [table value]
3 IN 1|2|3 //true
4 IN 1|2|3 //false
"a" IN "a"|"b"|"c" //true
"d" IN "a"|"b"|"c" //false
"3" IN 1|2|3 //true

NOT IN Operator (NOT IN)

The NOT IN operator (not in ) returns true if the right operand does not contain the left operand, and false otherwise.
  • Members of the set can be separated by pipe (|), comma (,), semicolon (;)
  • The right operand has to be an array []

NOT IN Operator examples:

[request value] NOT IN [table value]
3 NOT IN 1|2|3 //false
4 NOT IN 1|2|3 //true
"a" NOT IN "a"|"b"|"c" //false
"d" NOT IN "a"|"b"|"c" //true
"3" NOT IN 1|2|3 //false

Greater than OR Equal Operator (>=)

The greater than or equal operator (>=) returns true if the left operand is greater than or equal to the right operand, and false otherwise.
  • Numbers can be decimal or integer
  • String comparison is similar to JS​

Greater than OR Equal Operator examples:

[request value] >= [table value]
5 >= 3 // true
3.1 >= 2.1 // true
"b" >= "a" // true
"a" >= "a" // true
true >= true // true
true >= false // true

Greater Operator (>)

The greater operator (>) returns true if the left operand is greater than the right operand, and false otherwise.
  • Numbers can be decimal or integer
  • String comparison is similar to JS​

Greater Operator examples:

[request value] > [table value]
5 > 3 // true
3.1 > 2.1 // true
"b" > "a" // true
true > true // false
true > false // true

Less than OR Equal Operator (<=)

The less than or equal operator (<=) returns true if the left operand is less than or equal to the right operand, and false otherwise.
  • Numbers can be decimal or integer
  • String comparison is similar to JS​

Less than OR Equal Operator examples:

[request value] <= [table value]
3 <= 5 // true
3 <= 3 // true
2.1 <= 3.1 // true
"a" <= "a" // true
"a" <= "b" // true
true <= true // true
false <= true // true

Less than Operator (<)

The less than operator (<) returns true if the left operand is less than the right operand, and false otherwise.
  • Numbers can be decimal or integer
  • String comparison is similar to JS.

Less than Operator examples:

[request value] < [table value]
3 < 5 // true
2.1 < 3.1 // true
"a" < "b" // true
true < true // false
false < true // true

Between Operator (between)

The between operator (between) returns true if the left operand is between or equal to the right operand, and false otherwise.
  • The left operand can be Number, String, or Boolean
  • The right operand has to be an Array of two values

Between Operator examples:

[request value] between [table value]
4 between [3 and 5] // true
3 between [3 and 5] // true
4.0 between [3.0 and 5.5] // true
3.5 between [3.0 and 5.5] // true
"b" between ["a" and "c"] // true
"a" between ["a" and "c"] // true
true between [true and false] // true
true between [true and true] // true

Between Left Open Operator

The between left open operator (betweenLeftOpen) returns true if the request value falls between the interval excluding the lower limit (left value) and including the upper limit (right value). Otherwise it returns false.
  • The left operand can be Number, String, or Boolean
  • The right operand has to be an Array of two values
[request value] between [table value]
4 between [3 and 5] // true
3 between [3 and 5] // false
5.5 between [3.0 and 5.5] // true
3.0 between [3.0 and 5.5] // false
"b" between ["a" and "c"] // true
"a" between ["a" and "c"] // false
true between [false and true] // true
false between [false and true] // false

Between Right Open Operator

The between right open operator (betweenRightOpen) returns true if the request value falls between the interval including the lower limit (left value) and excluding the upper limit (right value). Otherwise it returns false.
  • The left operand can be Number, String, or Boolean
  • The right operand has to be an Array of two values
[request value] between [table value]
4 between [3 and 5] // true
5 between [3 and 5] // false
3.0 between [3.0 and 5.5] // true
5.5 between [3.0 and 5.5] // false
"b" between ["a" and "c"] // true
"c" between ["a" and "c"] // false
true between [false and true] // false
false between [false and true] // true

Not Equal Operator (<>)

Compares two scalar values. The not equal operator compares mainly:
  • String
  • Number
  • Boolean

Not Equal Operator examples:

[request value] <> [table value]
3 <> 3 //false
"3" <> 3 //false
3 <> 4 //true
true <> false //true

Is Null

The is null operator (IsNull) returns true if the value is empty.
[request value] isNull [table value]
null //true
{} //true
[] //true
"a" //false
3 //false
"" //false

Is Not Null

The is not null operator (isNotNull) returns true if the value is not empty.
[request value] isNotNull [table value]
"a" //true
3 //true
"" //true
null //false
{} //false
[] //false

Contains Text Operator (containsText)

The contains text operator (containsText) returns true if the left operand contains in the right operand, and false otherwise.
  • Members of the set can be separated by pipe (|), comma (,), semicolon (;)
  • The left operand can be Number, String, or Boolean or Array of these data types
  • It is matching not only the exact matches but also the substrings

Contains Text Operator examples:

[request value] containsText [table value]
[1,2,3] containsText "1" //true
[11,2,3] containsText "1" //true
[2,3,4] containsText "1" //false
"This is example 1,2,3 with true." containsText "1,2,3" //true
"This is example false or true." containsText "true or false" //false
"This is example true with false." containsText true //true

Contains In Operator (containsIn)

The contains in operator (containsIn) returns true if any of the elements in the right operand is included in the element/elements of the left operand. Otherwise false is returned.
​
  • true is returned when any of the elements in the right operand is included in any substring of the left operand.
  • Members of the set can be separated by pipe (|), comma (,), semicolon (;)
  • The left operand can be Number, String, Boolean or Array of these data types

Contains in Operator examples:

[request value] containsIn [table value]
"This is example 1 with true." containsIn 1|2|3 //true
"This is example 1 with true." containsIn 1|true|"ok" //true
"This is example 1 with true." containsIn "is"|2|true //true
"This is example 1 with true." containsIn true|3 //true
[1,2,3] containsIn true|3 //true
["true or falseee", "haha"] containsIn true|false //true
"This is example 1 with true." containsIn "test"|2 //false

Not Contains In Operator (notContainsIn)

The not contains in operator (notContainsIn) returns true if none of the elements in the right operand is included in the element/elements of the left operand. Otherwise false is returned.
  • Members of the set can be separated by pipe (|), comma (,), semicolon (;)
  • The left operand can be Number, String, Boolean or Array of these data types

Contains Text Operator examples:

[request value] notContainsIn [table value]
"This is example 1 with true." notContainsIn 2|3|4 //true
"This is example 1 with true." notContainsIn 2|false|"ok" //true
"This is example 1 with true." notContainsIn "are"|2|false //true
"This is example 1 with true." notContainsIn false|3 //true
[1,2,3] containsIn true|3 //false
["true or falseee", "haha"] containsIn "hello"|"bye" //true
"This is example 1 with true." notContainsIn "test"|1 //false

Equal Array Operator (equalArray)

The Equal Array operator ( equalArray ) returns true if all the values inside the right operand are substrings of one of the values inside left operand.
  • Members of the set can be separated by pipe (|), comma (,), semicolon (;)
  • The left operand has to be an array []

equalArray Operator examples:

[request value] equalArray [table value]
[1, 2, 3] equalArray 1|2|3 //true
["a", "b"] equalArray "a"|"b" //true
[1,2,3] equalArray 1|2 //true
[1111,111] equalArray 1|11|111 //true
[1,2,3,4,5] equalArray 1|2|3|4|6 //false

Else Operator (ELSE)

The ELSE is a special kind of operator, whose returned value is independent of the respective input variable of the column. Instead, the ELSE operator returns true if no row has passed up to the time of evaluation of the condition cell.
Note that by definition:
  • there can always be at most one passing row containing the ELSE operator
  • when the ELSE operator is evaluated, it only takes into account conditions above it
The ELSE operator allows you, among other things, to add a so-called default row to your decision table. It is simply a row at the end of the table with ELSE operator in all of its condition cells. By definition, the default row gets triggered whenever there is no other row passing. It can be used e.g. to send an error message to the output.
