After looking for a day I still don't get what I am doing wrong here. I want to select the column name in my table Laboratory in the server which contain 6 columns but I keep getting the error:
"SQLException:Column Index out of range: 0, number of columns: 1".
Is anyone familiar with this? Thanks
Here's my code:
String sql = "SELECT name FROM Laboratory";
RawSql rawSql = RawSqlBuilder
.parse(sql)
.create();
Query<Laboratory> query = Ebean.find(Laboratory.class);
query.setRawSql(rawSql).where();
List<Laboratory> results = query.findList();
results.sort(Comparator.comparing(Laboratory::getName)); // Sort by alphabetical order
try {
String json = JsonHelper.toJSON(results);
return ok(json).as("application/json");
} catch (JsonProcessingException e) {
LOG.error("Unable to serialize sql request", e);
return internalServerError();
}
Ok I have found the solution. It turns out that I just had to fetch the id in addition to the name or else Ebean was lost. In the end here is the sql request that works:
String sql = "SELECT id, name FROM Laboratory";
