The `QMYSQL` Qt driver contains a bug, if your table includes a `json` column type, then you must explicitly name columns other than `json` columns instead of the `*` shorthand, otherwise, you will get an empty result, or all column values will be invalid QVariant-s, or it may even return half of the columns. The `QPSQL` driver returns correct results and doesn't have problem with `json` columns.
