I am not sure that I understand clearly your problem. Are you sure that your
query's are written correctly?
For duplicates you can make a uniqe indexing so this will avoid any
dupplicates in your table.
CREATE UNIQUE INDEX table_column_uniqueidx ON table(column);
If the rows are dissapearing, please check your delete query, because that
is the only way to erase all rows from the table.
If still got problems, please post some queries, be more specific.
Best regards,
Andy.
