我想使用 SQL Server 中的存储过程将数据从一个表同时插入到另一个表中

Question

First Issue table

BookID | BookName | DateIssue | ReturnDate | PersonID
       |          |           |            |
1      | Sqlserver|  4/4/2015 |  5/5/2015  |  22

I want to insert the values from tblIssue into Return table but, couldn't... second Return table

BookID | BookName | DateIssue | ReturnDate | PersonID
       |          |           |            |
1      | Sqlserver|  4/4/2015 |  5/5/2015  |  22

query is running in sql server.. I thought, I have mistakes in sql server query

Stored proc query:



'CREATE PROCEDURE inserttwo
(
@BookID int,
@BookName nvarchar(50),
@DateIssue datetime,
@ReturnDate datetime,
@PersonID int
)

as

insert into tblReturn(BookID,BookName,DateIssue,ReturnDate,PersonID)
values(@BookID,@BookName,@DateIssue,@ReturnDate,@PersonID)

select * from  tblIssue

error in c#:

Procedure or function 'inserttwo' expects parameter '@BookID',
which was not supplied.

here it is pointing error: sda.Fill(dt);

C# code: 


 public void storedproc()
        {
      string w = ConfigurationManager.ConnectionStrings["LMS"].ConnectionString;
            SqlConnection conn = new SqlConnection(w);
            DataTable dt = new DataTable();
            SqlCommand cmd = new SqlCommand("inserttwo", conn);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlDataAdapter sda = new SqlDataAdapter(cmd);
            conn.Open();
            sda.Fill(dt);
            metroGrid1.DataSource = dt;
            conn.Close(); }

Answer 1

you have to add the parameters

string w = ConfigurationManager.ConnectionStrings["LMS"].ConnectionString;
using (SqlConnection conn = new SqlConnection(w))
{
    DataTable dt = new DataTable();
    using (SqlCommand cmd = new SqlCommand("inserttwo", conn))
    {
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.Add("@BookID", SqlDbType.Int).Value = BookID;
        cmd.Parameters.Add("@BookName", SqlDbType.NVarChar, 50).Value = BookName;
        cmd.Parameters.Add("@DateIssue", SqlDbType.DateTime).Value = Date;
        cmd.Parameters.Add("@ReturnDate", SqlDbType.DateTime).Value = ReturnDate;
        cmd.Parameters.Add("@PersonID", SqlDbType.Int).Value = PersonID;
        SqlDataAdapter sda = new SqlDataAdapter(cmd);
        conn.Open();
        sda.Fill(dt);
        metroGrid1.DataSource = dt;
    }
    conn.Close();
}

the procedure requires @BookID,@BookName,@DateIssue,@ReturnDate,@PersonID so you have to add them and fill them with values.

UPDATE To insert Data into 2 tables your procedure should look something like this without knowing your table structure it's impossible to give you a valid answer

'CREATE PROCEDURE inserttwo
(
@BookID int,
@BookName nvarchar(50),
@DateIssue datetime,
@ReturnDate datetime,
@PersonID int
)

as

insert into tblReturn(BookID,BookName,DateIssue,ReturnDate,PersonID)
values(@BookID,@BookName,@DateIssue,@ReturnDate,@PersonID)

insert into tblIssue(BookID,BookName,DateIssue,ReturnDate,PersonID)
values(@BookID,@BookName,@DateIssue,@ReturnDate,@PersonID)
