I am trying to get all records from a postgres database where the date_completed (timestamp without timezone) is between startoftoday and endoftoday. However I cannot get the ODATA query for less than or greater than to work. I keep getting this error.

Report{
"status": 400,
"message": "We cannot apply operator < to types DateTime and DateTimeZone.\r\n inner exception: We cannot apply operator < to types DateTime and DateTimeZone.\r\nclientRequestId: 12f42943-0acf-4b4a-a482-3d72ca9dbf98",
"source": "postgresql-eus.azconn-eus.p.azurewebsites.net"
}The odata filter is equal to
utcnow('yyyy-MM-ddTHH:mm:ssZ’) lt date_completedThis is the odata filter after the expressions run
2018-09-06T08:07:16Z lt date_completed
Couldn't use Azure Functions to access my database because it's on-prem and I don't want to pay for a VPN Gateway.
@ialastairhunter 2 great suggestions - Thank you!
The OData workaround was a bit painful as you suggested, but it works. Doing a "my_ts >= yyyy-mm-dd" filter ended up looking like this (for any that might find this thread later):
year(my_ts) gt yyyy or (year(my_ts) eq yyyy and (month(my_ts) gt mm or (month(my_ts) eq mm and day(my_ts) ge dd)))
I'll try the Azure Function next and post results (and probably code).
There are a few aditional options
1 - Create an Azure Function app that would take a HTTP Post with a sql query string and return JSON Object with the query results. Then use an HTTP Connector in flow to pass a SQL Query to the azure function app.
2 - Use an Azure Logic app instead of flow and you can call an azure function app, or execute some javascript right from the azure logic app.
@degvalentineI was able to solve this however it was not an ideal query. You will need to use the MONTH, DAY, and YEAR Functions in combintation with the greate than and less than operators.
For example if you wanted to compare the date was equal to 04/04/2013
month(DATE) eq 04 AND day(DATE) eq 04 AND year(DATE) eq 2013
I'm in the same boat. My research leads me to believe there is no solution. I hope I'm wrong and am still searching...
I believe our only hope is that Flow will add support for "Execute a query" to on-prem gateways. Here's a link to the community topic. Add your vote!
Using filter contains '2018-09-05' works but since the table has over a million rows the query takes 22 mins to execute if I don’t use the database engine to filter the results.
I will try the filter as you suggested but im sure if it does work the same issue will exist as the table just has too many rows.
Hi @elksson,
Could you please share a screenshot of the configuration of your flow?
Please take a try to add a "Filter array" action in your flow replace of the ODATA query, the flow should as below:
Best regards,
