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,

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS
$$
BEGIN
WITH m_ty_person AS (return query execute sql)
select name, count(*) from m_ty_person where name like '%a%' group by name
union
select name, count(*) from m_ty_person where gender = 1 group by name;
END
$$ LANGUAGE plpgsql;

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

ERROR: syntax error at or near "return"
LINE 5: WITH m_ty_person AS (return query execute sql)

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,

RETURN QUERY EXECUTE '
WITH m_ty_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM m_ty_person WHERE name LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM m_ty_person WHERE gender = 1 GROUP BY name$x$;

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

INSERT INTO ‘Tip’

По синтаксису (и стандарту SQL) insert запроса после ключевого слова into должно идти имя таблицы. Вы указали строковой литерал. Парсер соответственно удивляется и отвечает, что вы написали непонятно что.

  • в одинарных кавычках 'Tip' — строковой литерал.
  • без кавычек Tip — имя объекта, принудительно приводимое парсером к нижнему регистру, т.е. tip
  • в двойных кавычках "Tip" — регистрозависимое имя объекта

Если у вас таблица именно Tip, то единственным корректным способом к ней обращаться будут двойные кавычки:

INSERT INTO "Tip" ...

Здравствуйте! Довольно распространенный вопрос, находил решения, но все же компилятор выводит ошибку. Как-то неправильно задаю первичный ключ.

SQL-запрос пишу в консоли postgresql. Таблица без записей.
Также в проекте имеется обычный конфигурационный файл для JPA. Думаю, что роли он здесь не играет

@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.

pg_dump — это программа для создания резервных копий базы данных Postgres Pro.

При попытке восстановления дампа под Windopws 7 столкнулся с ошибкой:

COPY carriers (business_entity_id, name) FROM stdin;
8	Arriva
50000	ASEAG
.

[Err] ОШИБКА: ошибка синтаксиса (примерное положение: «8»)
LINE 2: 8 Arriva
^

Мы получаем простую синтаксическую ошибку, потому что Postgres получает данные как код SQL.

Пример ниже не поддерживается утилитой pgAdmin.

COPY tablel FROM STDIN;

Как сделать резервную копию базы в Postgress?

pg_dump -U user database > fileName.sql

где:

  • pg_dump это программа для создания резервных копий базы данных Postgres Pro;
  • postgres — имя пользователя БД (совпадает с именем базы данных);
  • transactions — имя базы к которой есть доступ у нашего пользователя postgres;
  • transactions.sql — имя создаваемого файла дампа;
  • hostname — имя сервера БД, это pg.sweb.ru;
  • format — формат дампа (может быть одной из трех букв: ‘с’ (custom — архив .tar.gz), ‘t’ (tar — tar-файл), ‘p’ (plain — текстовый файл). В команде букву надо указывать без кавычек.);
  • dbname — имя базы данных.
pg_dump -U postgres transactions > transactions.sql

Как сделать restore в Postgress?

Тут все несколько запутанней, поэтому выкладываю все 3 варианта начну с того который решил мою проблему:

psql -U postgres -d belgianbeers -a -f beers.sql

pg_restore -h localhost -U postgres -F t -d transactions «D:/transactions.sql»

pg_restore —host localhost —port 5432 —username postgres —dbname transactions —clean —verbose «D:transactions.sql»

Не забывайте если указываете полный путь брать его в двойные кавычки!!!

when I am using this command to update table in PostgreSQL 13:

UPDATE rss_sub_source 
SET sub_url = SUBSTRING(sub_url, 1, CHAR_LENGTH(sub_url) - 1) 
WHERE sub_url LIKE '%/'
limit 10

but shows this error:

SQL Error [42601]: ERROR: syntax error at or near "limit"
Position: 111

why would this error happen and what should I do to fix it?

LIMIT isn’t a valid keyword in an UPDATE statement according to the official PostgreSQL documentation:

[ WITH [ RECURSIVE ] with_query [, ...] ]
UPDATE [ ONLY ] table_name [ * ] [ [ AS ] alias ]
SET { column_name = { expression | DEFAULT } |
( column_name [, ...] ) = [ ROW ] ( { expression | DEFAULT } [, ...] ) |
( column_name [, ...] ) = ( sub-SELECT )
} [, ...]
[ FROM from_item [, ...] ]
[ WHERE condition | WHERE CURRENT OF cursor_name ]
[ RETURNING * | output_expression [ [ AS ] output_name ] [, ...] ]

Reference: UPDATE (PostgreSQL Documentation )

Solution

Remove LIMIT 10 from your statement.

You could make something like this

But a Limit without an ORDER BY makes no sense, so you must choose one that gets you the correct 10 rows

when I am using this command to update table in PostgreSQL 13:

UPDATE rss_sub_source SET sub_url = SUBSTRING(sub_url, 1, CHAR_LENGTH(sub_url) - 1) WHERE sub_url LIKE '%/' limit 10 

but shows this error:

SQL Error [42601]: ERROR: syntax error at or near "limit" Position: 111 

why would this error happen and what should I do to fix it?

LIMIT isn’t a valid keyword in an UPDATE statement according to the official PostgreSQL documentation:

[ WITH [ RECURSIVE ] with_query [, ...] ]
UPDATE [ ONLY ] table_name [ * ] [ [ AS ] alias ]
SET { column_name = { expression | DEFAULT } |
( column_name [, ...] ) = [ ROW ] ( { expression | DEFAULT } [, ...] ) |
( column_name [, ...] ) = ( sub-SELECT )
} [, ...]
[ FROM from_item [, ...] ]
[ WHERE condition | WHERE CURRENT OF cursor_name ]
[ RETURNING * | output_expression [ [ AS ] output_name ] [, ...] ]

Reference: UPDATE (PostgreSQL Documentation )

Solution

Remove LIMIT 10 from your statement.

You could make something like this

But a Limit without an ORDER BY makes no sense, so you must choose one that gets you the correct 10 rows

UPDATE rss_sub_source t1
SET t1.sub_url = SUBSTRING(t1.sub_url, 1, CHAR_LENGTH(t1.sub_url) - 1) 
FROM (SELECT id FROM rss_sub_source WHERE sub_url LIKE '%/' ORDER BY id LIMIT 10) t2 
WHERE t2.id = t1.id

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:

array(9) { 
    [0]=> string(15) "BvrK9z6UPxY.jpg" 
    [1]=> string(16) "1265dde1c67abc1c" 
    [2]=> string(23) "По умолчанию" 
    [3]=> int(54973) 
    [4]=> string(7) "720x430" 
    [5]=> NULL 
    [6]=> string(0) "" 
    [7]=> string(108) "files/id5cd487313a93a/По умолчанию/2019-05-10/1265dde1c67abc1c.jpg" 
    [8]=> string(15) "id5cd487313a93a" 
}

Сообщение ошибки:

Type: PDOException
Code: 42601
Message: SQLSTATE[42601]: Syntax error: 7 ОШИБКА: ошибка синтаксиса (примерное положение: "user") LINE 11: user ^

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

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,

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS
$$
BEGIN
WITH m_ty_person AS (return query execute sql)
select name, count(*) from m_ty_person where name like '%a%' group by name
union
select name, count(*) from m_ty_person where gender = 1 group by name;
END
$$ LANGUAGE plpgsql;

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

ERROR: syntax error at or near "return"
LINE 5: WITH m_ty_person AS (return query execute sql)

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,

RETURN QUERY EXECUTE '
WITH m_ty_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM m_ty_person WHERE name LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM m_ty_person WHERE gender = 1 GROUP BY name$x$;

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.
