net MVC 3存储过程从表中返回一个值
本文关键字:一个 返回 MVC 存储过程 net | 更新日期: 2023-09-27 18:00:35
我有要返回的SQL:
CREATE PROCEDURE [Zinc].[GetUserByEmail]
@Email nvarchar (256)
AS
SELECT zu.UserId FROM zinc.users zu WHERE zu.Email = @Email
到目前为止,在我的存储库中我有:
public int GetUserByEmail(string email)
{
using (SqlConnection conn = new SqlConnection(ZincModelContainer.CONNECTIONSTRING))
{
using (SqlCommand cmd = conn.CreateCommand())
{
conn.Open();
cmd.CommandType = System.Data.CommandType.StoredProcedure;
cmd.CommandText = "[Zinc].[GetUserByEmail]";
//not sure how to go from here?
}
return userId;
}
}
由于它是标量值,请使用:
cmd.Parameters.Add("@Email", SqlDbType.NChar).Value = email;
var UserId = cmd.ExecuteScalar();
cmd.Parameters.Add("@Email", SqlDbType.NChar).Value = email;
int UserId = cmd.ExecuteScalar();
Microsoft文档通常是最好的起点。请参阅:http://msdn.microsoft.com/en-us/library/877h0y3a.aspx以获取从SqlConnection读取的示例。
