% This is generated by ESQL's AbstractFunctionTestCase. Do no edit it. See ../README.md for how to regenerate it.

**Examples**

```esql
ROW a=["foo", "zoo", "bar"]
| EVAL j = MV_CONCAT(a, ", ")
```

| a:keyword | j:keyword |
| --- | --- |
| ["foo", "zoo", "bar"] | "foo, zoo, bar" |

To concat non-string columns, call [`TO_STRING`](/reference/query-languages/esql/esql-functions-operators.md#esql-to_string) first:

```esql
ROW a=[10, 9, 8]
| EVAL j = MV_CONCAT(TO_STRING(a), ", ")
```

| a:integer | j:keyword |
| --- | --- |
| [10, 9, 8] | "10, 9, 8" |
