Namespace: MySql.Data.MySqlClient
Assembly: MySql.Data (in MySql.Data.dll) Version: 6.9.9
Syntax
Copy
public MySqlCommand SelectCommand { get; set; }
Public Property SelectCommand As MySqlCommand

Property Value

Type: MySqlCommand
A MySqlCommand used during Fill(DataSet) to select records from the database for placement in the DataSet.
Remarks

When SelectCommand is assigned to a previously created MySqlCommand, the MySqlCommand is not cloned. The SelectCommand maintains a reference to the previously created MySqlCommand object.

If the SelectCommand does not return any rows, no tables are added to the DataSet, and no exception is raised.

Examples
The following example creates a MySqlDataAdapter and sets the SelectCommand and InsertCommand properties. It assumes you have already created a MySqlConnection object.
Copy
public static MySqlDataAdapter CreateCustomerAdapter(MySqlConnection conn)
{
MySqlDataAdapter da = new MySqlDataAdapter();
MySqlCommand cmd;
MySqlParameter parm;

// Create the SelectCommand.
cmd = new MySqlCommand("SELECT * FROM mytable WHERE id=@id AND name=@name", conn);

cmd.Parameters.Add("@id", MySqlDbType.VarChar, 15);
cmd.Parameters.Add("@name", MySqlDbType.VarChar, 15);

da.SelectCommand = cmd;

// Create the InsertCommand.
cmd = new MySqlCommand("INSERT INTO mytable (id,name) VALUES (@id,@name)", conn);
cmd.Parameters.Add("@id", MySqlDbType.VarChar, 15, "id" );
cmd.Parameters.Add("@name", MySqlDbType.VarChar, 15, "name" );

da.InsertCommand = cmd;

return da;
}
Public Shared Function CreateCustomerAdapter(conn As MySqlConnection) As MySqlDataAdapter

Dim da As MySqlDataAdapter = New MySqlDataAdapter()
Dim cmd As MySqlCommand
Dim parm As MySqlParameter

' Create the SelectCommand.
cmd = New MySqlCommand("SELECT * FROM mytable WHERE id=@id AND name=@name", conn)

cmd.Parameters.Add("@id", MySqlDbType.VarChar, 15)
cmd.Parameters.Add("@name", MySqlDbType.VarChar, 15)

da.SelectCommand = cmd

' Create the InsertCommand.

cmd.Parameters.Add( "@id", MySqlDbType.VarChar, 15, "id" )
cmd.Parameters.Add( "@name", MySqlDbType.VarChar, 15, "name" )
da.InsertCommand = cmd

Return da
