摘要:[LINQ] 如何调用 Stored Procedure From EntityFramework (2)
这次要说的是另一种读取方式,但是首先还是将Stored Procedure 加入Entity Model
如何加入请参考第一篇 : http://www.dotblogs.com.tw/constancy/archive/2013/10/31/126285.aspx
加入完之后,可用以下方式取得数据
EntityConnection entityConnection = (EntityConnection) this.context.Connection;
DbConnection storeConnection = entityConnection.StoreConnection;
//建构参数
SqlParameter parameter1= new SqlParameter("@parameter1", SqlDbType.Text);
//为参数赋予值
parameter1.Value = parameterValue;
storeConnection.Open();
using (DbCommand command = storeConnection.CreateCommand())
{
command.CommandText = "reg.getTapqSubinfo";
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add(parameter1);
//取得一列数据
var result = command.ExecuteReader(CommandBehavior.SingleRow);
if (result.Read())
//取得某一个字段的值
return result.GetString(3);
}
