The following code snippet demonstrates how to create a new table using the TAmazonTableService API:
Delphi:
var
ResponseInfo: TCloudResponseInfo;
TableService: TAmazonTableService;
TableName:String;
begin
TableName := 'TableName';
TableService := TAmazonTableService.Create(AmazonConnectionInfo1);
ResponseInfo := TCloudResponseInfo.Create;
try
if TableService.CreateTable(TableName, ResponseInfo) then
Memo1.Lines.Append('Success! Table: ' + TableName + ' created.')
else
Memo1.Lines.Append(Format('Failure! %s', [ResponseInfo.StatusMessage]));
finally
TableService.Free;
ResponseInfo.Free;
end;
end;
C++:
TCloudResponseInfo *ResponseInfo;
String TableName;
TAmazonTableService *TableService;
TableName = "TableName";
TableService = new TAmazonTableService(AmazonConnectionInfo1);
ResponseInfo = new TCloudResponseInfo;
try
{
if (TableService->CreateTable(TableName, ResponseInfo))
{
Memo1->Lines->Append("Success! Table: " + TableName + " created.");
}
else
{
TVarRec args[1] = {ResponseInfo->StatusMessage};
Memo1->Lines->Append(Format("Failure! %s", args, 0));
}
}
__finally
{
delete TableService;
delete ResponseInfo;
}
