In ADOdb, named quotes for MS SQL Server use ". From the MSSQL Docs:
Note Delimiters are for identifiers only. Delimiters cannot be used for keywords,

Quoted identifiers are delimited by double quotation marks ("):
SELECT * FROM "Blanks in Table Name"
Bracketed identifiers are delimited by brackets ([ ]):

Quoted identifiers are valid only when the QUOTED_IDENTIFIER option is set to ON. By default,
the Microsoft OLE DB Provider for SQL Server and SQL Server ODBC driver set QUOTED_IDENTIFIER ON

In Transact-SQL, the option can be set at various levels using SET QUOTED_IDENTIFIER,
the quoted identifier option of sp_dboption, or the user options option of sp_configure.
When SET ANSI_DEFAULTS is ON, SET QUOTED_IDENTIFIER is enabled.
