Grant Method (Table, View)
后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能,并着手修改当前还在使用该功能的应用程序。
The Grant method assigns a table permission or a list of permissions to one or more Microsoft SQL Server users or roles.
语法
object.Grant(Privilege,GranteeNames, [ ColumnNames ] ,
[ GrantGrant ] , [ AsRole ] )
Parts
object
Expression that evaluates to an object in the Applies To list.Privilege
Long integer that specifies one or more table permissions as described in Settings.GranteeNames
SQL Distributed Management Objects (SQL-DMO) multistring listing users or roles.ColumnNames
SQL-DMO multistring listing column names within the table or view. When used, the specified privilege is extended only to the columns named.GrantGrant
When TRUE, the grantee(s) specified are granted the ability to execute the GRANT statement referencing the table or view. When FALSE (default), the ability to extend permission is not granted.AsRole
String that identifies a role to which the connected user belongs as described in Remarks.
Prototype (C/C++)

SQLDMO_LPCSTR ColumnNames = NULL,
BOOL GrantGrant = FALSE,
SQLDMO_LPCSTR AsRole = NULL);

注释
When a user is a member of more than a single role, the user can have permission to grant access to a table or view under one role and not under another. In this case, SQL Server security mechanisms prevent execution of the Grant method on the Table or View object referencing the database object. Use the AsRole argument to specify the role under which permission to execute the grant exists.
For more information about setting multistring parameters, see Using SQL-DMO Multistrings.

---|
Granting permissions to database users and roles using the Grant method of the Table or View object requires appropriate privilege. The SQL Server login used for SQLServer object connection must be granted the ability to execute GRANT referencing the database object, the owner of the database object, or a member of a role with greater privilege. |
