java.sq.SQLException: Column not found

Question

I am receiving the following error:

HTTP Status 500 - Request processing failed; nested exception is
org.springframework.jdbc.BadSqlGrammarException: Stateme         


        

Answer 1

Check your SQL statement -- you need to include the category_id in the column list:

String sql = "SELECT id, name, category_id FROM track WHERE category_id = " + categoryId + " ORDER BY name";

It is failing because you're trying to extract category_id from the ResultSet and it isn't there.
