Error syntax error at or near name - Исправление ошибок и поиск оптимальных решений проблем

Last tested: Feb 2021

Overview

This SQL error generally means that somewhere in the query, there is invalid syntax.
Some common examples:

Using a database-specific SQL for the wrong database (eg BigQuery supports DATE_ADD, but Redshift supports DATEADD)
Typo in the SQL (missing comma, misspelled word, etc)
Missing a sql clause (missed from, join, select, etc)
An object does not exist in the database or is not accessible from the current query (eg referencing orders.id when there is no orders table joined in the current query, etc)

In some circumstances, the database error message may display extra detail about where the error was raised, which can be helpful in narrowing down where to look.

Error Message

SQL ERROR: syntax error at or near

Troubleshooting

This should generally be the first step to troubleshoot any SQL syntax error in a large query: iteratively comment out blocks of SQL to narrow down where the problem is.

TIP: To make this process easier, change the group by clause to use position references
eg: group by 1,2,3,4,5 instead of group by orders.status, orders.date, to_char(...)...
as well as separate the where and having clauses onto multiple lines.

So for example, say we have the following query:

play_arrow

WITH cte AS (
select id, status, sales_amountfrom orders
)
select status, foo.date, sum(cte.sales_amount), count(*) from cte
join foo on cte.date = foo.date
group by status, foo.date
order by 3 desc

We could start by running just the portion in the CTE:

play_arrow

-- WITH cte AS (
select id, status, sales_amountfrom orders
-- )
-- select status, foo.date, sum(cte.sales_amount), count(*)
-- from cte
-- join foo on cte.date = foo.date
-- group by 1, 2
-- order by 3 desc

Then strip out the aggregates and portions related to them

play_arrow

WITH cte AS (
    select id, status, sales_amountfrom orders
)
select status, foo.date, -- sum(cte.sales_amount), count(*)
from cte
join foo on cte.date = foo.date
-- group by 1, 2
-- order by 3 desc

Iteratively stripping out / adding back in portions of the query until you find the minimum query to trigger the error.

Lookup functions and syntax If the query is small enough, or if we’ve narrowed the scope enough with 1, google all the functions used in the query and verify that they exist and are being used correctly.
Verify all objects exist Verify that you’ve joined all tables used in the select, where, and having clause, and that those tables exist in the db. Once we’ve narrowed things down from 1, also check that each column exists in the table specified.

@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.

CREATE TABLE IF NOT EXISTS "__EFMigrationsHistory" (
    "MigrationId" varchar(150) NOT NULL,
    "ProductVersion" varchar(32) NOT NULL,

I have checked, syntax is ok maybe problem is somewhere in other place?

Delimiter is included between server and port.

Also in same advanced editor I see that syntax is ok

So I am not sure where the problem is with'[‘ as error message in previous message. Error message appears when I am on table, selecting table.
