我对 Entity Framework 6 非常陌生，我想在我的项目中实现存储过程。我有一个存储过程如下：
ALTER PROCEDURE [dbo].[insert_department]
@Name [varchar](100)
AS
BEGIN
INSERT [dbo].[Departments]([Name])
VALUES (@Name)
DECLARE @DeptId int
SELECT @DeptId = [DeptId]
FROM [dbo].[Departments]
WHERE @@ROWCOUNT > 0 AND [DeptId] = SCOPE_IDENTITY()
SELECT t0.[DeptId]
FROM [dbo].[Departments] AS t0
WHERE @@ROWCOUNT > 0 AND t0.[DeptId] = @DeptId
END
Department class:
public class Department
{
public int DepartmentId { get; set; }
public string Name { get; set; }
}
modelBuilder
.Entity<Department>()
.MapToStoredProcedures(s =>
s.Update(u => u.HasName("modify_department")
.Parameter(b => b.Department, "department_id")
.Parameter(b => b.Name, "department_name"))
.Delete(d => d.HasName("delete_department")
.Parameter(b => b.DepartmentId, "department_id"))
.Insert(i => i.HasName("insert_department")
.Parameter(b => b.Name, "department_name")));
protected void btnSave_Click(object sender, EventArgs e)
{
string department = txtDepartment.text.trim();
// here I want to call the stored procedure to insert values
}
我的问题是：如何调用存储过程并向其中传递参数？
您可以在您的存储过程中调用DbContext类如下。
this.Database.SqlQuery<YourEntityType>("storedProcedureName",params);
但是，如果您的存储过程返回多个结果集作为示例代码，那么您可以在 MSDN 上查看这篇有用的文章
