Supported Data Types

Data types in Decision Tables

All data in a decision table is stored as string values and is automatically cast when needed. Therefore, you don’t need to specify any data format for your input and output models. The automatic casting of conditions and results is described in the following sections.

Condition Data Types

Conditions can be created using the following scalar data types:

• Number

• Boolean

• String

• Date

And collection data types:

• JSON Array

The decimal separator is always a dot: 5.5

Solver Request Data Example

The inputs below demonstrate the format in which you can send a request to match a particular row:

1. Number:

   {
     "input": "2.31"
   }

   or

   {
     "input": 2.31
   }

2. Boolean (True):

   {
     "input": true
   }

   or

   {
     "input": "true"
   }

3. Boolean (False):

   {
     "input": false
   }

   or

   {
     "input": "false"
   }

4. String:

   {
     "input": "hello world"
   }

5. Date and Time:

   {
     "input": "2024-09-23 13:27 +02:00"
   }

   or as extended ISO-8601:

   {
     "input": "2024-09-23T13:27:00+02:00"
   }

6. Array:

   {
     "input": ["first", 2, false]
   }

7. Empty Value:

   {
     "input": ""
   }

The data cells now convert dates to strings. The old object format is deprecated but still supported. For example, the input:

{
"input": {
    "date": "2024-09-23",
    "time": "13:27",
    "timezone": "+02:00"
    }
}   

will match the new condition 2024-09-23 13:27 +02:00.

Examples:

Condition [value in decision table]	Solver Request Value [value send on API]	Result
2.31	2.31	Equal
2.31	"2.31"	Equal
true	true	Equal
true	"true"	Equal
false	false	Equal
true	2	Not Equal
hello world	"hello world"	Equal
"2024-09-23 13:27 +02:00"	"2024-09-23 13:27 +02:00"	Equal
"2024-09-23 13:27 +02:00"	"2024-09-23T13:27:00+02:00"	Equal
"2024-09-23 13:27 +02:00"	{ "input": { "date": "2024-09-23", "time": "13:27", "timezone": "+02:00" } }	Equal
"2021-03-17T13:17-09:00"	"2024-09-23 13:27 +02:00"	Equal
"2021-03-17T13:17-09:00"	{ "input": { "date": "2024-09-23", "time": "13:27", "timezone": "+02:00" } }	Not Equal!
<empty>	""	Equal
<empty>	Value not presented in input JSON	Not Equal

Calculation Data Types

Calculation columns support all the data types used by result columns.

Result Data Types

When calling the Solver API, the response returns an array of results based on the decision table setup. Response values are automatically cast to the following data types:

• Boolean

• Number

• String

• Date

• JSON Object

• JSON Array

Casting examples:

Decision Table Result Value	Solver Response Value
true	true
false	false
"true"	\"true\"
25	25
25.0	25
25.01	25.01
""	""
Empty	""
hello world	"hello world"
DATE(09.23.2024)	"2024-09-22T22:00"
{}	{}
{"data":123 }	{"data":123 }
{"data": "123" }	{"data": "123" }
[12,36,"542"]	[12,36,"542"]
[12,36,"542"	"[12,36,\"542\""
[12, 36, "542", [1,2] ]	[12, 36, "542", [1,2] ]
