Dim gsCommand As New GBaseCommand(gsSelectQuery)

gsCommand.Connection = New GBaseConnection(gsConnectString)

gsCommand.CommandType = CommandType.Text

End Sub

[C#]

public void CreateGBaseCommand()

{

string gsSelectQuery = "SELECT * FROM gstable ORDER BY id";

string gsConnectString = "Persist

SecurityInfo=False;database=test;

server = gsServer";

GBaseCommand gsCommand = new GBaseCommand(gsSelectQuery);

gsCommand.Connection = new GBaseConnection(gsConnectString);

gsCommand.CommandType = CommandType.Text;
