Checks if the given dataset is empty.
Performs a null check, height > 0 and width > 0 checks. It is useful when writing server side services and it is needed to check if the dataset is not null and have content.
Keep in mind that having a NULL dataset if far different from having an empty dataset. While making queries to databases using afgs API (afgs_command_execute_single_query) it could happen that this function returns an empty dataset. This means that the query requested was sucessfully completed but no data was found.
If the previous function return a NULL dataset means there was an error. As a conclusion:
- Only use this function if the process at the server side to program some service which needs to check for emptyness.
- Cases where this function is useful are those where it is expected to receive, at least, one row.
|dataset ||The dataset to check|
- TRUE if the given dataset is not null and have at least one row and one column.
