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 ” |
