通过ADO可以访问SQL SERVER，并执行相应的SQL语句建库、建表，下面是SQL SERVER BOOKS ONLINE中的相关定义。

  建表：

CREATE TABLE
[
    database_name.[owner].
    | owner.
] table_name
(
    {
        | column_name AS computed_column_expression

    } [,...n]
)
[ON {filegroup | DEFAULT} ]
[TEXTIMAGE_ON {filegroup | DEFAULT} ]

::= { column_name data_type }
[ [ DEFAULT constant_expression ]
| [ IDENTITY [(seed, increment ) [NOT FOR REPLICATION] ] ]
]
[ ROWGUIDCOL ]
[ ] [ ...n]

::= [CONSTRAINT constraint_name]
{
    [ NULL | NOT NULL ]
    | [    { PRIMARY KEY | UNIQUE }
        [CLUSTERED | NONCLUSTERED]
        [WITH FILLFACTOR = fillfactor]
        [ON {filegroup | DEFAULT} }
     ]
    | [    [FOREIGN KEY]
        REFERENCES ref_table [(ref_column) ]
        [NOT FOR REPLICATION]
     ]
    | CHECK [NOT FOR REPLICATION]
        (logical_expression)
}

::= [CONSTRAINT constraint_name]
{
    [ { PRIMARY KEY | UNIQUE }
        [ CLUSTERED | NONCLUSTERED]
        { ( column[,...n] ) }
        [ WITH FILLFACTOR = fillfactor]
        [ON {filegroup | DEFAULT} ]
    ]
    | FOREIGN KEY
            [(column[,...n])]
            REFERENCES ref_table [(ref_column[,...n])]
            [NOT FOR REPLICATION]
    | CHECK [NOT FOR REPLICATION]
        (search_conditions)
}

  建库：

CREATE DATABASE database_name
[ ON [PRIMARY]
        [ [,...n] ]
        [, [,...n] ]
]
[ LOG ON { [,...n]} ]
[ FOR LOAD | FOR ATTACH ]

::=

  ( [ NAME = logical_file_name, ]
  FILENAME = 'os_file_name'
  [, SIZE = size]
  [, MAXSIZE = { max_size | UNLIMITED } ]
  [, FILEGROWTH = growth_increment] ) [,...n]

::=

FILEGROUP filegroup_name [,...n]
