Hi,
Can some one help me how to create nested Arrays..
Here is the JSON message:
{"name": "DiwRule3", "contactFilterRules": [
{
"contactFieldId": 16,
"type": "SYSTEM_ARRAY",
"operator": "IN",
"dataType": "NUMBER",
"columnName": "groups",
"contactFilterOption": "IN",
"columnValue": [
8105621194808290, 8105621194808291
]
}]
}
I had a hard time to create ColumnValue array
here is my ESQL:
SET OutputRoot.JSON.Data.name = UPPER(Environment.DFDL.ns:ContactEmployeeDetails.Group);
CREATE FIELD OutputRoot.JSON.Data.contactFilterRules IDENTITY(JSON.Array)contactFilterRules;
SET OutputRoot.JSON.Data.contactFilterRules.Item[1].contactFieldId = '16';
SET OutputRoot.JSON.Data.contactFilterRules.Item[1].type = 'SYSTEM_ARRAY';
SET OutputRoot.JSON.Data.contactFilterRules.Item[1].operator = 'IN';
SET OutputRoot.JSON.Data.contactFilterRules.Item[1].dataType = 'NUMBER';
SET OutputRoot.JSON.Data.contactFilterRules.Item[1].columnName = 'groups';
SET OutputRoot.JSON.Data.contactFilterRules.Item[1].contactFilterOption = 'IN';
How to write logic for Column Value..? Please help.
Thanks,
Soudhanya |

There's a standard approach for this sort of thing:
1. Create the JSON message that you want IIB to write
2. Add a Trace node to your message flow. Set the Pattern property to ${Root}
3. Parse the JSON message
4. Inspect the Trace node output
5. Modify your ESQL until the message tree that you send to the output node looks exactly like the message tree produced by the JSON parser |

Give this guy a medal.This worked.
I was trying to write a SELECT on JSON and then i realized the syntax is different from XML to JSON.You have to append 'Item' word after any array.
Example: SELECT I from InputRoot.JSON.Data.Files.Item[] AS I |

He's a smart guy. IBM should offer him a job. And a raise.
Another approach, though not as standard, is to consult the documentation, and then search for any relevant information, such as this, or this, or this. |

Goes without saying.
