SqlBatchCommand()

Initializes a new SqlBatchCommand.

Examples

The following example creates a SqlConnection and a SqlBatch, then adds multiple SqlBatchCommand objects to the batch. It then executes the batch, creating a SqlDataReader. The example reads through the results of the batch commands, writing them to the console. Finally, the example closes the SqlDataReader and then the SqlConnection as the using blocks fall out of scope.

using Microsoft.Data.SqlClient;

class Program
{
    static void Main()
    {
        string str = "Data Source=(local);Initial Catalog=Northwind;"
        + "Integrated Security=SSPI;Encrypt=False";
        RunBatch(str);
    }

    static void RunBatch(string connString)
    {
        using var connection = new SqlConnection(connString);
        connection.Open();

        using var batch = new SqlBatch(connection);

        const int count = 10;
        const string parameterName = "parameter";
        for (int i = 0; i < count; i++)
        {
            var batchCommand = new SqlBatchCommand($"SELECT @{parameterName} as value");
            batchCommand.Parameters.Add(new SqlParameter(parameterName, i));
            batch.BatchCommands.Add(batchCommand);
        }

        var results = new List<int>(count);
        using (SqlDataReader reader = batch.ExecuteReader())
        {
            do
            {
                while (reader.Read())
                {
                    results.Add(reader.GetFieldValue<int>(0));
                }
            } while (reader.NextResult());
        }
        Console.WriteLine(string.Join(", ", results));
    }
}

SqlBatchCommand(String, CommandType, IEnumerable<SqlParameter>, SqlCommandColumnEncryptionSetting)

Initializes a new SqlBatchCommand.

public SqlBatchCommand (string commandText, System.Data.CommandType commandType = System.Data.CommandType.Text, System.Collections.Generic.IEnumerable<Microsoft.Data.SqlClient.SqlParameter> parameters = default, Microsoft.Data.SqlClient.SqlCommandColumnEncryptionSetting columnEncryptionSetting = Microsoft.Data.SqlClient.SqlCommandColumnEncryptionSetting.UseConnectionSetting);

new Microsoft.Data.SqlClient.SqlBatchCommand : string * System.Data.CommandType * seq<Microsoft.Data.SqlClient.SqlParameter> * Microsoft.Data.SqlClient.SqlCommandColumnEncryptionSetting -> Microsoft.Data.SqlClient.SqlBatchCommand

Public Sub New (commandText As String, Optional commandType As CommandType = System.Data.CommandType.Text, Optional parameters As IEnumerable(Of SqlParameter) = Nothing, Optional columnEncryptionSetting As SqlCommandColumnEncryptionSetting = Microsoft.Data.SqlClient.SqlCommandColumnEncryptionSetting.UseConnectionSetting)

Parameters

commandText

String

The text of the SqlBatchCommand.

commandType

CommandType

Indicates how the CommandText property is to be interpreted.

parameters

IEnumerable<SqlParameter>
