Examples

The following example creates multiple instances of MySqlParameter through the MySqlParameterCollection collection within the MySqlDataAdapter. These parameters are used to select data within the data source and place the data in the DataSet. This code assumes that a DataSet and a MySqlDataAdapter have already been created with the appropriate schema, commands, and connection.

CopyVB.NET

Public Sub AddParameters()
' ...
' create myDataSet and myDataAdapter
' ...
myDataAdapter.SelectCommand.Parameters.Add("@CategoryName", MySqlDbType.VarChar, 80).Value = "toasters"
myDataAdapter.SelectCommand.Parameters.Add("@SerialNum", MySqlDbType.Long).Value = 239

myDataAdapter.Fill(myDataSet)
End Sub 'AddSqlParameters

CopyC#

public void AddSqlParameters()
{
// ...
// create myDataSet and myDataAdapter
// ...

myDataAdapter.SelectCommand.Parameters.Add("@CategoryName", MySqlDbType.VarChar, 80).Value = "toasters";
myDataAdapter.SelectCommand.Parameters.Add("@SerialNum", MySqlDbType.Long).Value = 239;
myDataAdapter.Fill(myDataSet);
