.Net下调用SqlServer2k存储过程

首先,在SqlServer中创建存储过程,在调用时分为有参数和没有参数两种情况,   先就简单的没有参数的情况简要的介绍:   假设存储过程如下: CREATE PROC SelectAll   AS   SELECT * FROM StudentInf   则此sp的调用如下:   SqlCommand selectCMD = new SqlCommand(“SelectAll”, conn);   //conn 为SqlConnection   selectCMD.CommandType = CommandType.StoredProcedure;   如果需要将结果集加到某个DataAdapter上,则可如下:   SqlDataAdapter stuDA = new SqlDataAdapter();   stuDa.SelectCommand = selectCMD;   如果有参数:create proc andSelect   @StudentId varchar(10),   @StudentName varchar(10),   As   Select * from StudentInf where StudentId = @StudentId and StudentName = @StudentName   则参数可以如下添加:   selectCMD.Parameters.Add(“@StudentId”, SqlDbType.NVarChar, 10);   selectCMD.Parameters.Add(“@StudentName”, SqlDbType.NvarChar, 10);   如果只有一个参数,也可以这样赋值:   SqlParameters onePara = selectCMD.Parameters.Add(“@StudentId”, SqlDbType.NVarChar, 10);   onePara.Value = “ a string ”
