执行SQL 任务使用不同的连接类型时,SQL 命令的语法使用不同的参数标记。例如,ADO.NET 连接管理器类型要求 SQL 命令使用格式为@varParameter的参数标记,而 OLE DB 连接类型要求使用问号 (?) 参数标记。 在变量与参数之间的映射中可以用作参数名的名称也因连接管理器类型而异。例如,ADO.NET 连接管理器类型使用带 @ 前缀的用
EXECUTE<ProcedureName> N'<Parameter 1 value>, N'<Parameter xvalue>; GO 例如,以下 Transact-SQL 语句执行uspGetCustomerCompany存储过程,将Cannon作为@LastName参数值,将Chris作为@FirstName参数值: SQL EXEC SalesLT.uspGetCustomerCompany N'Cannon', N'Chris'; GO ...
