    sql - Cannot fetch a row from OLE DB provider "ADSDSOObject" for linked server "ADSI" - Stac

    I have a SQL Function that calls OpenQuery to return the sAMAccountName for a given @displayname.

    If I call the function, I get the error:

    Cannot fetch a row from OLE DB provider "ADSDSOObject" for linked server "ADSI"

    If I use a SQL select that calls the OpenQuery, it works.

    select sAMAccountName from OpenQuery (ADSI, 'SELECT sAMAccountName, displayname FROM ''LDAP://mydomain'' WHERE objectCategory=''user''') where displayname = 'Doug Kimzey'

    The function below always returns the error.

    ALTER FUNCTION [dbo].[cus_GetADLogin]
(   @displayName varchar(64) )
RETURNS VARCHAR(128)
AS
BEGIN
    declare @sAMAccountName varchar(128)
    
    SET @sAMAccountName = (SELECT sAMAccountName FROM 
                    OpenQuery (ADSI, 'SELECT sAMAccountName, displayname FROM ''LDAP://mydomain'' WHERE objectCategory=''user''') AD
                   where AD.displayName = @displayName)

    RETURN @sAMAccountName
END

    Would anyone know why the SELECT...OpenQuery works outside of the function but fails when executed inside a function?

    Reset to default 1

    Wouldn't this work?

    ALTER FUNCTION [dbo].[cus_GetADLogin]
(   @displayName varchar(64) )
RETURNS VARCHAR(128)
AS
BEGIN
    declare @sAMAccountName varchar(128)
    
    SELECT @sAMAccountName = sAMAccountName FROM 
                    OpenQuery (ADSI, 'SELECT sAMAccountName, displayname FROM ''LDAP://mydomain'' WHERE objectCategory=''user''') AD
                   where AD.displayName = @displayName;

    RETURN @sAMAccountName
END
