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 ...
1 正常存储过程带RETURN(只能返回整型) CREATE PROCEDURE p_test1 AS DECLARE @int int SET @int = 102400; RETURN @int;--这里只能返回整型 --执行 DECLARE @p1return INT --声明一个变量 EXECUTE @p1return= p_test1 --使用变量来接收 return回来的值 SELECT @p1return 2带OUTPUT参数的存储过程 CREATE PR...
DECLARE@ReturnintEXEC@Return=spTestReturns//第一个RETURNSELECT@Return //返回100 5、执行存储过程: 对于调用存储过程需要注意以下几点: 对于存储过程声明中的输出参数,需要使用OUTPUT关键字。 和声明存储过程时一样,调用存储过程时,必须使用OUTPUT关键字。这样就对SQL Server作了提前通知,告诉它参数所需要的特殊处理。
In this scenario, the output parameters of the SP are returned correctly in the first call (by using sp_prepexecrpc). However, subsequent calls (by using sp_execute) of the SP may not return the parameters ...

SQL Server stored procedures have four mechanisms used to return data:Each SELECT statement in the procedure generates a result set. The procedure can return data through output parameters. A cursor output parameter can pass back a Transact-SQL server cursor. The procedure c...

OUTPUT Indicates that the parameter is an output parameter. The value of this option can be returned to the calling EXECUTE statement. Use OUTPUT parameters to return values to the caller of the procedure. text, ntext, and image parameters cannot be used as OUTPUT parameters, unless the procedu...
