Description
- I have a MySQL database as a source for a QL-chart.
- I have a parameter (string) that can have one or multiple values.
- According to the documentation, “If the query contains the IN operator before a parameter, the substituted value is always converted into a tuple. Such a query will work correctly if you select one or more values.”
- However, when I use only one value, it doesn’t work as expected — the value is not converted into a tuple and remains a string.
