The error message is complaining about parsing. The opening (after the function) and closing (after the qi) brackets are missing. Reading error messages is usually the first thing you ought to do, as it might tell you what the query engine thinks is the problem, or give you sufficient hints to put you into the ballpark.

The information field will display the syntax of a function when you click on it.

You should also be aware of what functions are supported by whatever Database vendor you are using as it is preferable to use a native function, as that will mean that the probability of local processing will be reduced as it would be more likely to be pushed down to the data base for processing.
