What happened?

It's just link:

TABLE row.file.aliases AS "Aliases",
link(file.link, file.aliases) AS Link,
GROUP BY file.folder

[mrwhaler]

TABLE 
link(file.link, file.aliases) AS Link
GROUP BY file.folder

Grouping does not display anything

Can you show us what the output of this query is? Full output won't be necessary and feel free to strip out sensitive info.

```dataview
table 
  file.folder
```

I will explain what I want to do. I need a list (rows) where the name of the link is replaced (by another value) and it can be grouped.

I imagined it like this: rows.link(file.link, file.aliases) AS Link

[AB1908]

table without id
  link(rows.file.path, rows.file.aliases) as Link,
  rows.file.name
from "Folder"
group by file.aliases

Note that all files without aliases will be grouped together.

[mrwhaler]

Is there an opportunity to make grouping on folders (first column) and change the name of the link to the file with its pseudular (second column)?

| Folders Group | Link (file.link as aliases) |
| ------------- | --------------------------- |
| /folder/      | - 1                         |
|               | - 2                         |
|               | - 3                         |
|               | - 4                         |
|               | - 5                         |
| ---           | ---                         |
| /folder2/     | - 6                         |
|               | - 7                         |
|               | - 8                         |
|               | - 9                         |
|               | - 10                        |

For the next query, two prior conditions:

1. always a defined alias;
2. only one alias.

TABLE rows.LK as Link
FLATTEN link(file.link, file.aliases) AS LK
GROUP BY file.folder

Please explain the meaning of the "Flatten" operator

[AB1908]

Separates a result having multiple results in a cell (as a list) into separate entries. https://blacksmithgu.github.io/obsidian-dataview/query/queries/#flatten

Hi, is this still an issue?
