| 14 | In ADOdb, named quotes for MS SQL Server use ". From the MSSQL Docs: |
---|
| 15 | |
---|
| 16 | Note Delimiters are for identifiers only. Delimiters cannot be used for keywords, |
---|
| 17 | whether or not they are marked as reserved in SQL Server. |
---|
| 18 | |
---|
| 19 | Quoted identifiers are delimited by double quotation marks ("): |
---|
| 20 | SELECT * FROM "Blanks in Table Name" |
---|
| 21 | |
---|
| 22 | Bracketed identifiers are delimited by brackets ([ ]): |
---|
| 23 | SELECT * FROM [Blanks In Table Name] |
---|
| 24 | |
---|
| 25 | Quoted identifiers are valid only when the QUOTED_IDENTIFIER option is set to ON. By default, |
---|
| 26 | the Microsoft OLE DB Provider for SQL Server and SQL Server ODBC driver set QUOTED_IDENTIFIER ON |
---|
| 27 | when they connect. |
---|
| 28 | |
---|
| 29 | In Transact-SQL, the option can be set at various levels using SET QUOTED_IDENTIFIER, |
---|
| 30 | the quoted identifier option of sp_dboption, or the user options option of sp_configure. |
---|
| 31 | |
---|
| 32 | When SET ANSI_DEFAULTS is ON, SET QUOTED_IDENTIFIER is enabled. |
---|
| 33 | |
