No result was found for query although at least one row was expected

Question

I have the following code:

/**
     * Search similar category given a string
     * 
     * @param $searchTerm search similar category
     */
    public fun         


        

Answer 1

You are getting this error because you are using the getSingleResult() method. it generates an Exception if it can't find even a single result. you can use the getOneOrNullResult() instead to get a NULL if there isn't any result from the query.

Query#getSingleResult(): Retrieves a single object. If the result contains more than one object, an NonUniqueResultException is thrown. If the result contains no objects, an NoResultException is thrown. The pure/mixed distinction does not apply.
