Hi,
I have a SQL result set that includes a varchar array as one of the
columns. I'm mapping over the Result<Record> returned by fetch() and
manually populating a pojo but I'm having trouble populating the String[]
array field of the pojo.
d.fetch("select array_agg(some_field) as theArray from sometable group by
some_field")
.stream()
.map(r -> {
SalesTouchPoint stp = new SalesTouchPoint();
stp.setAudience(r.getValue("people", Integer.class));
stp.setEpc(r.getValue("epc", Double.class));
stp.setTouchPoints(r.getValue("theArray", String[].class
));
return stp;
})
.collect(Collectors.toList());
As you can see from the above code I'm using Record.getValue (or
Record.get) to access the column "theArray" from the result set. I'm
getting a class cast exception:
Caused by: org.jooq.exception.DataTypeException: Cannot convert from [Ljava.
lang.String;@5a6782c3 (class java.lang.String) to class [Ljava.lang.String;

Everything I've read in the docs suggests that JOOQ handles SQL array types
just fine. What am I doing wrong?
