Question

I’m having trouble adding a “where x in (select …)” statement to my linq query.
The query represents a Master [MEDIEN] / Detail [EXEMPLARE] scenario.

The missing where statement should represent the following SQL:

WHERE e.EXEMPLARSTATUS IN (SELECT EXEMPLARSTATUS FROM ANYTABLE)

Dim eMedien = ( _
    From p In db.MEDIEN _
    Where p.MEDIENNR = "1235155"
    Select New With {.HST = p.HST,
        .ANYNAME = ( _
        From e In p.EXEMPLAR _
        **** WHERE QUERY ****
        Select New With {.ZWEIGSTELLE = e.ZWEIGSTELLE, .EXEMPLARSTATUS = e.EXEMPLARSTATUS})
                    })

Any help is apreciated!

Answer 1

WHERE e.EXEMPLARSTATUS IN (SELECT EXEMPLARSTATUS FROM ANYTABLE)

This part of your query should be written as

where (from EXEMPLARSTATUS in ANYTABLE select EXEMPLARSTATUS).Contains(e.EXEMPLARSTATUS)
