Ошибка 42601 postgresql

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
  RETURNS TABLE (name text, rowcount int)
  LANGUAGE plpgsql AS 
$func$
BEGIN
   RETURN QUERY EXECUTE '
   WITH v_tb_person AS (' || sql || $x$)
   SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
   UNION
   SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;
END     
$func$;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work.

I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish — though I wouldn’t even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It’s impossible to make this secure.

Craig (a sworn enemy of SQL injection) might get a light stroke when he sees what you forged from his answer to your preceding question.

The query itself seems rather odd, btw. The two SELECT terms might be merged into one. But that’s beside the point here.

Добрый вечер. Есть выражение:

$this->insertStmt = $this->connection->getPdo()->prepare("
    INSERT INTO files (
           real_name, 
           virtual_name, 
           album,
           size,
           resolution, 
           duration, 
           comment,
           path,
           user
    ) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)
");

Которое вызывается как обычно:

protected function doInsert(object $object)
{
    $values = [
        $object->getRealName(),
        $object->getVirtualName(),
        $object->getAlbum(),
        $object->getSize(),
        $object->getResolution(),
        $object->getDuration(),
        $object->getComment(),
        $object->getPath(),
        $object->getUser(),
    ];
       
    $this->insertStmt->execute($values);
}

Примерное содержание $values:

С точки зрения синтаксиса вроде все верно, много раз перепроверил, IDE ни на что не ругается. В чем трабл, господа?

PostgreSQL error 42601- How we fix it

by Sijin George | Sep 12, 2019

Syntax errors are quite common while coding.

But, things go for a toss when it results in website errors.

PostgreSQL error 42601 also occurs due to syntax errors in the database queries.

At Bobcares, we often get requests from PostgreSQL users to fix errors as part of our Server Management Services.

Today, let’s check PostgreSQL error in detail and see how our Support Engineers fix it for the customers.

What causes error 42601 in PostgreSQL?

PostgreSQL is an advanced database engine. It is popular for its extensive features and ability to handle complex database situations.

Applications like Instagram, Facebook, Apple, etc rely on the PostgreSQL database.

But what causes error 42601?

PostgreSQL error codes consist of five characters. The first two characters denote the class of errors. And the remaining three characters indicate a specific condition within that class.

Here, 42 in 42601 represent the class “Syntax Error or Access Rule Violation“.

In short, this error mainly occurs due to the syntax errors in the queries executed. A typical error shows up as:

Here, the syntax error has occurred in position 119 near the value “parents” in the query.

How we fix the error?

Now let’s see how our PostgreSQL engineers resolve this error efficiently.

Recently, one of our customers contacted us with this error. He tried to execute the following code,

But, this ended up in PostgreSQL error 42601. And he got the following error message,

Our PostgreSQL Engineers checked the issue and found out the syntax error. The statement in Line 5 was a mix of plain and dynamic SQL. In general, the PostgreSQL query should be either fully dynamic or plain. Therefore, we changed the code as,

This resolved the error 42601, and the code worked fine.

Conclusion

In short, PostgreSQL error 42601 occurs due to the syntax errors in the code. Today, in this write-up, we have discussed how our Support Engineers fixed this error for our customers.

@YohDeadfall — I understand that part about it, but this is not script that I am creating or even code that I am creating. This is all created under the hood by Npsql/EntityFramework. My quick guess is that I am extending my DbContext from IdentityDbContext<IdentityUser> which wants to create all of the tables for roles, users, claims, etc. If I change this to just extend from DbContext, then everything works as advertised.

Below is the script that EF is trying to use created from dotnet ef migrations script — please be aware that I have removed my custom part of the script for brevity.

You can see there are two specific calls that are being made where [NormalizedName] and [NormalizedUserName] are being used.
