Question

In my Java code, I have something like this :

ResultSet rs = statement.executeQuery(
                   "SELECT a,b,c FROM foo -- here starts the long query"+
                   " -- that is not yet finished " +
                   " -- that still has something to say... "+ 
                   " -- now the end !"
               );

I would like to clean up my code like this :

ResultSet rs = statement.executeQuery(all_queries.getQuery("The very long one"));

I have read that ResourceBundle is for localization. So I don’t think it matches in my case.

What should all_queries be ?

EDIT :
The most important thing for me is to clean up the code.

Answer 1

I would put it in a file with an sql extension and implement Queries like:

Queries {
    static public String getQuery(String name) {
        return loadResource("/com/example/queries/" + name + ".sql");
    }
}

User:

conn.prepareStatement(Queries.getQuery("my_query"));

Of course that’s only one way to do it. You can make Queries return Statement, or even use a dynamic proxy to mask it behind a simple Java interface (where proxy handler could create statement, set parameters and run query). Your mileage may vary.

Added benefit: sql files have syntax coloring and are way easier to maintain than Strings in Java.
