### EF.Functions.JsonPathExists()

EF Core 11 introduces `EF.Functions.JsonPathExists()`, which checks whether a given JSON path exists in a JSON document. On SQL Server, this translates to the [`JSON_PATH_EXISTS`](/sql/t-sql/functions/json-path-exists-transact-sql) function (available since SQL Server 2022).

The following query filters blogs to those whose JSON data contains an `OptionalInt` property:

```csharp
var blogs = await context.Blogs
.Where(b => EF.Functions.JsonPathExists(b.JsonData, "$.OptionalInt"))
.ToListAsync();
```

This generates the following SQL:

```sql
SELECT [b].[Id], [b].[Name], [b].[JsonData]
FROM [Blogs] AS [b]
WHERE JSON_PATH_EXISTS([b].[JsonData], N'$.OptionalInt') = 1
```

`EF.Functions.JsonPathExists()` accepts a JSON value and a JSON path to check for. It can be used with scalar string properties, complex types, and owned entity types mapped to JSON columns.

For the full `JSON_PATH_EXISTS` SQL Server documentation, see [`JSON_PATH_EXISTS`](/sql/t-sql/functions/json-path-exists-transact-sql).
