Hi all,
Martijn, a user of Npgsql, sent me a query which is giving problems with
postgresql using extended query mode.
The problem I'm having is in the Parse message. The parse message I'm
sending is as follow:
select * from table where $1 in (select some_field from table)
Postgresql returns this error:
could not determine data type of parameter $1
Severity: ERROR
Code: 42P18
But I already have many working samples in the form for example:
insert into table(field1, field2) values ($1, $2)
The only way I could have it working was by adding the explicit type of
parameter so the parse text is, for example for parameter of type text:
select * from table where $1::text in (select some_field from table)
Is this a bug in Postgresql or is this by design?
Thanks in advance.
Regards,
Francisco Figueiredo Jr.
