Asp.net 如何在使用c#.net的SQL Server 2008中使用1个insert存储过程插入5行

我必须使用Asp.net在一个表中保存5个文件路径，并使用一次存储过程调用，后端是SQL Server 2008

如果使用表值参数，则非常欢迎

请尽快回复我

谢谢。

假设您有这样一张桌子：

CREATE TABLE dbo.FileTest 
(
     ID INT NOT NULL IDENTITY(1,1), 
     FileName VARCHAR(255), 
     DateInserted DATETIME2(3)
)

// define some strings we need - connection string, name of stored procedure, name of the table type
string connectionString = "server=.;Database=test;Integrated Security=SSPI;";
string storedProcedureName = "dbo.InsertFileNames";
string tvpValueTypeName = "FileNameType";

// set up data to insert - create a DataTable that has the same structure as your TVP type in SQL Server
DataTable filesNamesToAdd = new DataTable();
filesNamesToAdd.Columns.Add(new DataColumn("FileName", typeof (string)));

// insert some rows into that DataTable
DataRow row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\autoexec.cmd";
filesNamesToAdd.Rows.Add(row);

row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\Windows\\Explorer.exe";
filesNamesToAdd.Rows.Add(row);

row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\Windows\\starter.xml";
filesNamesToAdd.Rows.Add(row);

row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\Windows\\WindowsUpdate.log";
filesNamesToAdd.Rows.Add(row);

row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\Windows\\mip.bin";
filesNamesToAdd.Rows.Add(row);

// set up SqlConnection and SqlCommand in using blocks
using(SqlConnection conn = new SqlConnection(connectionString))
using (SqlCommand insertCommand = new SqlCommand(storedProcedureName, conn))
{
    // define the SqlCommand to be a stored procedure we're calling
    insertCommand.CommandType=CommandType.StoredProcedure;

    // define the table-valued parameter; it's of type SqlDbType.Structured, and you need to tell it the TVP type in SQL Server
    SqlParameter tvpParam = insertCommand.Parameters.Add("@TVP", SqlDbType.Structured);
    tvpParam.TypeName = tvpValueTypeName;
    tvpParam.Value = filesNamesToAdd;

    // open connection, call the stored procedure to insert data, close connection 
    conn.Open();
    insertCommand.ExecuteNonQuery();
    conn.Close();
}

然后您需要创建一个表类型，它可以用作表值参数：

CREATE TYPE FileNameType AS TABLE (FileName VARCHAR(255));

接下来，您需要定义一个以该表类型为参数的存储过程，并将来自TVP的数据插入表中：

CREATE PROCEDURE dbo.InsertFileNames
    @TVP FileNameType READONLY
AS 
    SET NOCOUNT ON

    INSERT INTO FileTest(FileName, DateInserted)
       SELECT FileName, Sysdatetime()
       FROM  @TVP;

现在，在C#代码中，需要有如下内容：

CREATE TABLE dbo.FileTest 
(
     ID INT NOT NULL IDENTITY(1,1), 
     FileName VARCHAR(255), 
     DateInserted DATETIME2(3)
)

// define some strings we need - connection string, name of stored procedure, name of the table type
string connectionString = "server=.;Database=test;Integrated Security=SSPI;";
string storedProcedureName = "dbo.InsertFileNames";
string tvpValueTypeName = "FileNameType";

// set up data to insert - create a DataTable that has the same structure as your TVP type in SQL Server
DataTable filesNamesToAdd = new DataTable();
filesNamesToAdd.Columns.Add(new DataColumn("FileName", typeof (string)));

// insert some rows into that DataTable
DataRow row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\autoexec.cmd";
filesNamesToAdd.Rows.Add(row);

row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\Windows\\Explorer.exe";
filesNamesToAdd.Rows.Add(row);

row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\Windows\\starter.xml";
filesNamesToAdd.Rows.Add(row);

row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\Windows\\WindowsUpdate.log";
filesNamesToAdd.Rows.Add(row);

row = filesNamesToAdd.NewRow();
row["FileName"] = "C:\\Windows\\mip.bin";
filesNamesToAdd.Rows.Add(row);

// set up SqlConnection and SqlCommand in using blocks
using(SqlConnection conn = new SqlConnection(connectionString))
using (SqlCommand insertCommand = new SqlCommand(storedProcedureName, conn))
{
    // define the SqlCommand to be a stored procedure we're calling
    insertCommand.CommandType=CommandType.StoredProcedure;

    // define the table-valued parameter; it's of type SqlDbType.Structured, and you need to tell it the TVP type in SQL Server
    SqlParameter tvpParam = insertCommand.Parameters.Add("@TVP", SqlDbType.Structured);
    tvpParam.TypeName = tvpValueTypeName;
    tvpParam.Value = filesNamesToAdd;

    // open connection, call the stored procedure to insert data, close connection 
    conn.Open();
    insertCommand.ExecuteNonQuery();
    conn.Close();
}
