Sql error 0 sqlstate 42883

Всем сообщениям, которые выдаёт сервер Postgres Pro , назначены пятисимвольные коды ошибок, соответствующие кодам « SQLSTATE » , описанным в стандарте SQL. Приложения, которые должны знать, какое условие ошибки имело место, обычно проверяют код ошибки и только потом обращаются к текстовому сообщению об ошибке. Коды ошибок, скорее всего, не изменятся от выпуска к выпуску Postgres Pro , и они не меняются при локализации как сообщения об ошибках. Заметьте, что отдельные, но не все коды ошибок, которые выдаёт Postgres Pro , определены стандартом SQL; некоторые дополнительные коды ошибок для условий, не описанных стандартом, были добавлены независимо или позаимствованы из других баз данных.

Согласно стандарту, первые два символа кода ошибки обозначают класс ошибок, а последние три символа обозначают определённое условие в этом классе. Таким образом, приложение, не знающее значение определённого кода ошибки, всё же может понять, что делать, по классу ошибки.

В Таблице A.1 перечислены все коды ошибок, определённые в Postgres Pro 9.5.20.1. (Некоторые коды в настоящее время не используются, хотя они определены в стандарте SQL.) Также показаны классы ошибок. Для каждого класса ошибок имеется « стандартный » код ошибки с последними тремя символами 000 . Этот код выдаётся только для таких условий ошибок, которые относятся к некоторому классу, но не имеют более определённого кода.

Символ, указанный в столбце « Имя условия » , определяет условие в PL/pgSQL . Имена условий могут записываться в верхнем или нижнем регистре. (Заметьте, что PL/pgSQL , в отличие от ошибок, не распознаёт предупреждения; то есть классы 00, 01 и 02.)

Для некоторых типов ошибок сервер сообщает имя объекта базы данных (таблица, столбец таблицы, тип данных или ограничение), связанного с ошибкой; например, имя уникального ограничения, вызвавшего ошибку unique_violation . Такие имена передаются в отдельных полях сообщения об ошибке, чтобы приложениям не пришлось извлекать его из возможно локализованного текста ошибки для человека. На момент выхода PostgreSQL 9.3 полностью охватывались только ошибки класса SQLSTATE 23 (нарушения ограничений целостности), но в будущем должны быть охвачены и другие классы.

Database isn’t recognizing created function? SQL State: 42883

NULL My function was created successfully, however when I attempt to use it I get the error message:

ERROR: function coalesce2(character varying, character varying, character varying, character varying, character varying, character varying, character varying, character varying, character varying, character varying, character varying, character varying, character varying, character varying, character varying) does not exist SQL state: 42883 Hint: No function matches the given name and argument types. You may need to add explicit type casts.

The purpose of my function is to grab the first NON NULL value and compare it to the value to the right of it. If the value to the right is not NULL then I will use that value, if it is then I use the COALESCE value. My function is as follows:

Here is the function in use:

coalesce2 ( vw_header_to_node_13.subsetname, vw_header_to_node_12.subsetname, vw_header_to_node_11.subsetname, vw_header_to_node_10.subsetname, vw_header_to_node_9.subsetname, vw_header_to_node_8.subsetname, vw_header_to_node_7.subsetname, vw_header_to_node_6.subsetname, vw_header_to_node_5.subsetname, vw_header_to_node_4.subsetname, vw_header_to_node_3.subsetname, vw_header_to_node_2.subsetname, vw_header_to_node_1.subsetname, vw_header_to_node.subsetname, vw_header_to_node.setname) AS prctr2

I don’t have much experience with functions and I can’t understand why it isn’t recognizing the newly created function. Any advice is greatly appreciated.

SQL state: 42883, No function matches the given name and argument types. But that function actually exists

I have a server with PostgreSQL 8.1.23, with a function that works perfectly when it runs with postgres user, but with another user shows the SQL STATE:

This is my function:

If I run this with postgres user like this:

The result is like this:

But if I execute the same query as someuser, shows me this message:

Even if a do a explicit cast I get the same result:

Same error message.

What can I do so someuser can execute the same function?
Is there something wrong with my function or cast?

1 Answer 1

Most probably a matter of schema vs. schema search_path . The function is created in the default schema of the creating user. If that’s not in the search_path of the current user, it’s not visible.

Typically, you would create public functions in the schema public and have that schema in everbody’s search_path .

Schema-qualification is only needed if public isn’t the default schema anyway.

Also, your GRANT commands make no sense. The EXECUTE privilege for functions is granted to public by default. And once you grant to public , there is no need to grant to other users. Especially not to postgres , which is the OWNER anyway and a superuser, too. The manual:

PostgreSQL grants default privileges on some types of objects to PUBLIC . [. ] EXECUTE privilege for functions;

You do need to grant USAGE on the SCHEMA where the function is created. The public schema grants USAGE to public (everyone) by default.

Casting to integer does not change anything here because a numeric literal without decimal point is coerced to integer automatically. Details about constants in the manual.

Error: pgsql.PostgresException : 42883: function pg_try_advisory_lock(key := bigint) does not exist #2780

Npgsql version: 4.1.2
PostgreSQL version: 9.2.15
Operating system: CentOS 7.5

I am using C#/Mono to do the query of below:
«select count(*) from pg_locks where locktype=’advisory’»;
with,
NpgsqlCommand _command.ExecuteScalar();

It reports below error:
42883: function pg_try_advisory_lock(key := bigint) does not exist

I am able to use this proc inside the pgsql directly on this DB instance as below:

postgres=# select pg_try_advisory_lock(1);
pg_try_advisory_lock

Any help will be appreciated. Thanks a lot.

The text was updated successfully, but these errors were encountered:

Can you please post the actual C# Npgsql code where you’re trying to invoke pg_try_advisory_lock ? Above I can only see a query doing select count(*) from pg_locks which doesn’t seem relevant.

According to the error message, the parameter you’re passing to pg_try_advisory_lock has the wrong type (bigint instead of int).

The code triggers this error is here — looks it is triggered with a long value: ResourceID
(static long DBAccess.Resources.consolidation_intervals = 11, which the GetSqlType() in below AddParameters() returns as:
case TypeCode.Int64:
result = NpgsqlDbType.Bigint;
then it caused to invoke the pg_try_advisory_lock(key := bigint).

So in my understanding, the resourceID — static long in C# translated to BigInt is making sense. Also we treat the pg_try_advisory_lock as a procedure call here based on the sql sentence. but looks it still triggered the missing function error of missing function pg_try_advisory_lock(key := bigint). And the Postgres DB 9.2 do also have the pg_try_advisory_lock(big int) function — https://www.postgresql.org/docs/9.2/functions-admin.html

Could you pls suggest? thanks

I’ve done some more digging. The issue isn’t with the parameter type, but with the fact that a name is specified. In PostgreSQL you can call a function with positional ( SELECT * FROM foo(8) or named ( SELECT * FROM foo(bar => ) argument style. Unfortunately it seems that like many other internal functions, pg_try_advisory_lock does not actually have parameter names, so you can only call it positionally. To do this, do not set the NpgsqlParameter’s name («key») — just leave it empty. This will make PostgreSQL generate the positional style, which should work.

For reference, the following reproduces your issue:

While the following works:

The query that shows method along with their parameter names and types:

For proname=’pg_try_advisory_lock’, the proargnames column doesn’t contain names like for other functions.

Thanks roji for the debug.

is this a regression issue? we can use this way to invoke this function with previous version NPGSQL libary (e.g. v3.0.7, i,.e. before the above mentioned PR).

BTW, I even got the same errors even I invoke the procedure by given parameter name — e.g. below exception stack which is calling my internal private procedures what has character varying or String[] type are getting this failure.

Call: StoredProcedure
Params List: Param to String:Npgsql.NpgsqlParameter

Could you pls suggest how do we should write the procedures call in C# with these cases? thanks a lot.

PostgreSQL ERROR: there is no built-in function named » (SQL state 42883)

I’m trying to add to my PostgreSQL a very simple function, to convert IP addresses from an integer to a text format.

This is the code of the function:

As replay I’m obtaining the following error:

And some lines below.

Please let me know if anyone can see my mistake here, I’ve been trying different syntaxes and search information for the specific SQL state but no clue about what’s going on.

Thanks in advance.

There are two errors here:

1. PostgreSQL uses the standard string concatenation operator || like almost all other databases
2. There is no convert function in PostgreSQL, you should use to_char() to convert a number to a string

Btw: are you aware that there is a native IP data type available in PostgreSQL?

Additionally to what a_horse_with_no_name already pointed out:

• Use language plpgsql instead of language internal
• MySQL and others have tinyint . In PostgreSQL use smallint or int2 (synonym) instead. See the manual about data types. Better yet, make all variables bigint in this particular case and save an extra conversion.
• Use the assignment operator := instead of = . = is undocumented and may stop working without notice in a future version. See here: The forgotten assignment operator «=» and the commonplace «:=»
• Move END; to the end.
• Output is guaranteed to be the same for the same input, so make the function IMMUTABLE to speed it up in certain situations.

Any help with this would be very very very gratefully received

Oh and as a side note, is there any way to set Exception handlers globally for Tomcat? For example if anywhere in the app there is say a connection timeout, I can catch that in one place and deal with it?
