+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,
+ whether or not they are marked as reserved in SQL Server.
+
+ Quoted identifiers are delimited by double quotation marks ("):
+ SELECT * FROM "Blanks in Table Name"
+
+ Bracketed identifiers are delimited by brackets ([ ]):
+ SELECT * FROM [Blanks In Table Name]
+
+ 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
+ when they connect.
+
+ 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.
+
+ Syntax
