Re: Error while calling proc with table type from Application (npgsql)

Hi Justin,

Thanks for  your response. We have a user defined type created as below and we need to pass this user defined parameter to a procedure from .net code. Basically the procedure needs to accept  multiple rows as parameters(user defined table type). This happened seamlessly in SQL Server but while doing it in Postgres after migration we get the error mentioned in the above chain. Is theere any way we can achieve this?

CREATE TYPE public.optiontype AS (

projectid integer,

optionid integer,

phaseid integer,

remarks text

);

Regards,

Aditya.

What is PROCEDURE ABC ?  If you created it, send its definition with your problem report.

How are you executing it?  This seems like an error from npgsl, not postgres.
It may be a client-side error, and it may be that the query isn't even being
sent to the server at that point.

Did you do this ?
