Shopware Frontend 500 | SQLSTATE[42S22]: Column not found: 1054 Unknown column '/' in 'field list'

I´m currently trying to move Shopware 6 to a new Hoster (root Server). I copied the DB, set-up the server and the Webspace and I´m able to log in into the Backend. But when I´m in the frontend I get a 500 error, which is why I activated Shopware Debug.

There I got the following error: Could not connect to database. Message from SQL Server: An exception occurred while executing 'SELECT CONCAT(TRIM(TRAILING "/" FROM domain.url), "/") key, CONCAT(TRIM(TRAILING "/" FROM domain.url), "/") url, LOWER(HEX(domain.id)) id, LOWER(HEX(sales_channel.id)) salesChannelId, LOWER(HEX(sales_channel.type_id)) typeId, LOWER(HEX(domain.snippet_set_id)) snippetSetId, LOWER(HEX(domain.currency_id)) currencyId, LOWER(HEX(domain.language_id)) languageId, LOWER(HEX(theme.id)) themeId, sales_channel.maintenance maintenance, sales_channel.maintenance_ip_whitelist maintenanceIpWhitelist, snippet_set.iso as locale, theme.technical_name as themeName, parentTheme.technical_name as parentThemeName FROM sales_channel INNER JOIN sales_channel_domain domain ON domain.sales_channel_id = sales_channel.id LEFT JOIN theme_sales_channel theme_sales_channel ON sales_channel.id = theme_sales_channel.sales_channel_id INNER JOIN snippet_set snippet_set ON snippet_set.id = domain.snippet_set_id LEFT JOIN theme theme ON theme_sales_channel.theme_id = theme.id LEFT JOIN theme parentTheme ON theme.parent_theme_id = parentTheme.id WHERE (sales_channel.type_id = UNHEX(?))

Infos:

• Shopware Version 6.2.3
• PHP 7.2
• MySQL 8.0.30
• Linux Ubuntu 22.04 LTS 64-bit
• Apache
• SQL Mode Settings (ANSI,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION,NO_ZERO_DATE,NO_ZERO_IN_DATE,STRICT_ALL_TABLES)

(Please ask if you need the version of something else) (The DNS of the Domain currently shows to the live-page. I adjusted my local system so that I go to the new Hosting when I type the URL of the live-page. For that I used the /System32/drivers/etc/hosts file. I can explain more detailed if necessary.)

What I tried:

• Adding and removing "/" in Sales Channels URLs
• Checked the Sales-Channels DB Tables
• Checked where the Code comes from (RequestTransformer.php = vendor->shopware->storefront->Framework->Routing)
• Clearing Caches
• Regenerate Indizes
• Restarted Server and Apache
• Checked the Logs
• DB access is correct and works
• DB Tables are present
• Apache Memory is at 512M
• I checked via Shell the Memory and more than half of it was free / unused.
• Checked permissions in Shopware folder
• Suggestions from other people in reports I found on stackoverflow and Shopware community (None of these worked or were relatable to my problem)
• Compiled Theme again

What I´expecting: I need a functional Storefront that´s the same as the curent live so we can change the Domain DNS to the new Hosting. Rigth now I need the 500 error/Shopware error to be fixed.

The comment from "Álvaro González" helped. "I don't know anything about Shopware but it's using a non-standard syntax for strings ("/" instead of '/'). That fails if your MySQL server (as it seems to be the case) has ANSI_QUOTES enabled."

I deleted the "ANSI," value from my sql_mode from my database and the error was gone. Then I had another error but that one isn´t related to this post so I view this one as fixed. I just needed to access the storefront with the storefront URL and everything works now.
