Why Does Filtering a datetimeoffset Column in Azure Logic App Return No Data?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm trying to filter data in a Logic App SQL action using a datetimeoffset column but getting no results.

I have a table A with a column UpdatedAt (type: datetimeoffset(0)). I'm using the following SQL query:

SQL
SELECT * 
FROM A 
WHERE UpdatedAT = '2025-01-17 19:31:58 +2:00'

This query returns no results. However, when I use a similar filter in the Logic App SQL action, I get an empty result as well:

Here is a sample of the Logic App with table filtering by datetime:

JSON
{
    "definition": {
        "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
        "actions": {
            "Get_import_id_which_are_currently_in_progress": {
                "type": "ApiConnection",
                "description": "New/updated batch of rows via custom SQL in SQL Server\nBatch\n\nIf TaskState = 'COMPLETE' or 'CANCELLED'",
                "inputs": {
                    "host": {
                        "connection": {
                            "referenceName": "sql-1"
                        }
                    },
                    "method": "get",
                    "path": "/v2/datasets/@{encodeURIComponent(encodeURIComponent(parameters('SQL_SERVER_C')))},@{encodeURIComponent(encodeURIComponent('Apax_CoreServices'))}/tables/@{encodeURIComponent(encodeURIComponent('[A].[A]'))}/items",
                    "queries": {
                        "$filter": "UpdatedAt eq '2025-01-17T19:31:58Z'"
                    }
                },
                "runAfter": {}
            }
        },
        "contentVersion": "1.0.0.0",
        "outputs": {},
        "triggers": {
            "manualTrigger": {
                "type": "Request",
                "kind": "Http",
                "inputs": {
                    "schema": {}
                }
            }
        }
    },
    "kind": "Stateful"
}

What is causing the filter to return no data and how can I fix it?

The issue is that the date literal you use in your query does not match the stored value because of the time zone offset conversion. In your SQL query you use:

SQL
WHERE UpdatedAT = '2025-01-17 19:31:58 +2:00'

This literal represents a local time with an offset of +2. When you use the Logic App filter, however, the value is written as:

JSON
"$filter": "UpdatedAt eq '2025-01-17T19:31:58Z'"

Here the time is represented in UTC (with the "Z" suffix). Although both may refer to the same moment in time if correctly converted, SQL Server compares the entire datetimeoffset value (date, time, and offset).

For example, if the stored value is actually "2025-01-17 19:31:58 +2:00":

That value in UTC is "2025-01-17 17:31:58Z" (subtracting 2 hours).
Your Logic App filter "2025-01-17T19:31:58Z" does not match because it represents a time 2 hours later than the UTC equivalent.

To fix the problem you should ensure that the literal in your comparison exactly matches what is stored. You have a couple of options:

Adjust the Literal to the Correct Time Zone:
If your data truly is stored as "2025-01-17 19:31:58 +2:00", then use the same literal value (or its equivalent UTC version) in your filter. For example, either use:
- SQL query:
```
SQL
SELECT *
FROM A
WHERE UpdatedAT = '2025-01-17T19:31:58+02:00'
```
- Or if you want to use UTC in your filter, convert the stored datetimeoffset to UTC:
```
SQL
SELECT *
FROM A
WHERE UpdatedAT = '2025-01-17T17:31:58Z'
```
Use a Conversion Function:
You can convert the stored datetimeoffset to a specific time zone for comparison. For example, using the SQL Server function SWITCHOFFSET:
```
SQL
SELECT *
FROM A
WHERE SWITCHOFFSET(UpdatedAT, '+00:00') = '2025-01-17T17:31:58Z'
```
This converts the stored value to UTC before the comparison.

By ensuring that the datetime literal (including its offset) matches the stored data, your queries in both SQL and Logic App should return the expected results.

I also have a column UpdatedAt with value 2025-01-17 19:31:58 +2:00 in table A. I have created a standard stateful logic app to fetch this row using Get Rows (V2) action.

I have created a workflow with given action in it.

enter image description here

Code :-

JSON
{
    "definition": {
        "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json-",
        "actions": {
            "Get_rows_(V2)": {
                "type": "ApiConnection",
                "inputs": {
                    "host": {
                        "connection": {
                            "referenceName": "sql-1"
                        }
                    },
                    "method": "get",
                    "path": "/v2/datasets/@{encodeURIComponent(encodeURIComponent('default'))},@{encodeURIComponent(encodeURIComponent('default'))}/tables/@{encodeURIComponent(encodeURIComponent('[dbo].[A]'))}/items",
                    "queries": {
                        "$filter": "UpdatedAt eq '2025-01-17 19:31:58 +02:00'"
                    }
                },
                "runAfter": {}
            }
        },
        "contentVersion": "1.0.0.0",
        "outputs": {},
        "triggers": {
            "When_a_HTTP_request_is_received": {
                "type": "Request",
                "kind": "Http"
            }
        }
    },
    "kind": "Stateful"
}

Please ensure that the value you are using in the filter query should match with the data present in the UpdatedAt column.

I am able to get the expected response.
