Question

I have this basic consult is sql, but is giving me this error in management studio:

SELECT * 
FROM [Oficios_dev2].[dbo].[doc].[typecdocumentdet] as [C] 
where [C].[TypeCDocument] in (select [Oficios_dev2].[dbo].[doc].[TypeCDocument] as [D] 
                              where [D].[Id] = '1')

Error

Msg 4104, Level 16, State 1, Line 3
The multi-part identifier "D.Id" could not be bound.
Msg 4104, Level 16, State 1, Line 3
The multi-part identifier "Oficios_dev2.dbo.doc.TypeCDocument" could not be bound.

I have no idea why , anyone? Thanks

EDIT: New query:

SELECT *
FROM [Oficios_dev2].[dbo].[doc] as [C] where [C].[TypeCDocument]  in (select [Oficios_dev2].[dbo].[doc] from [Oficios_dev2].[dbo].[doc] as [D] where [D].[Id] = '1')

this gives me less errors still 1

The multi-part identifier "Oficios_dev2.dbo.doc" could not be bound.

Answer 1

the inner query is not formatted correctly:

you have:

(select [Oficios_dev2].[dbo].[doc].[TypeCDocument] as [D] where [D].[Id] = '1')

should by something like this:

(select TypeCDocument FROM [Oficios_dev2].[dbo].[doc] as [D] where [D].[Id] = '1')

Answer 2

You should test the inner query that you're using. It should be able to run independently of the full query. In this example, the inner query does not have the correct` syntax.

SELECT * 
FROM [Oficios_dev2].[dbo].[typecdocumentdet] as [C] 
where [C].[TypeCDocument] in (select [TypeCDocument]
                              from [Oficios_dev2].[dbo].[doc] as [D] 
                              where [D].[Id] = '1')

Note: I'm assuming that [doc] is the name of the table you want to the inner query to run on, and the [TypeCDocument] is the column you want to select for use by the IN expression list.
