Dear All,
I'm facing a general problem and I'm looking the best, fastest, way
how to identify the problem and solve it.
As example assume we have a function like that:
CREATE OR REPLACE FUNCTION testBinding01 (
p_in01 bigint,
p_in02 bigint,
p_in03 bigint,
p_in04 bigint,
p_in05 bigint,
p_in06 bigint,
p_text7 text
) RETURNS text
LANGUAGE sql
AS $$
select 'ciao';
$$;
I can call the function in some of the variant below:
select testBinding01(1,2,3,4,5,6,7);
select testBinding01(p_in01 => 1,p_in02 => 2,p_in03 => 3,p_in04 =>
4,p_in05 => 5,p_in06 => 6,p_text7 => 7);
select testBinding01(p_in01 => 1,p_in02 => 2,p_in03 => 3,p_in04 =>
4,p_in05 => 5,p_in06 => 6,p_text9 => 'some txt');
All of the above, produce the error:
*No function matches the given name and argument types.*
In psql what does:
\df test*
return for the function name.
I'm going to guess it might be testBinding01, in other words mixed case.
Have you tried?:
select "testBinding01"(1,2,3,4,5,6,7);
Forget the above. Instead:
select testBinding01(1,2,3,4,5,6,7);
ERROR: function testbinding01(integer, integer, integer, integer,
integer, integer, integer) does not exist
LINE 1: select testBinding01(1,2,3,4,5,6,7);
select testBinding01(1,2,3,4,5,6,'7');
testbinding01
---------------
ciao
The complete error shows what the function is receiving, all integers
when it needs a text parameter for the last value.

My question is: how is the best way to identify the problem?
Is a parameter name? is a parameter type? is the function name?
An especially in case is a parameter type how is the easy way to
identify which parameter is causing the problem?
In case a function has a lot of parameters (and in even worst case has
some overloading) going trough all parameters to check its type/name
costs a lot of time.
Thanks for any help
