New OpenJSON expression to SQL translation breaks aggregates on subquery with 'Cannot perform an aggregate function on an expression containing an aggregate or a subquery' exception #32374
Description
File a bug
Include your code
Steps to reproduce:
- Use attached example OpenJsonBug.zip
- Create db '''OpenJsonBugDb''' and table (no data is needed to reproduce) on local sql server
CREATE TABLE [dbo].[Sales](
[DateID] [int] NOT NULL,
[JOURNALID] [int] NOT NULL,
[FiltersService] [int] NOT NULL,
[OrdersGrossPCS] [decimal](18, 4) NULL,
[OrdersApprovedPCS] [decimal](18, 4) NULL,
[OrdersNetPCS] [decimal](18, 4) NULL,
[StatusNameLine] [varchar](9) NULL
) ON [PRIMARY]
- TestHashSetTranslation completes normally, TestArrayTranslation fails with
Microsoft.Data.SqlClient.SqlException : Cannot perform an aggregate function on an expression containing an aggregate or a subquery.
