For a set of sql-queries, how do you determine which result-set contains a certain row?

I have a set of sql - queries:

List<String> queries = ...
queries[0] = "select id from person where ...";
...
queries[8756] = "select id from person where ...";

Each query selects rows from the same table 'person'. The only difference is the where-clause. Table 'person' looks like this:

   id | name | ... many other columns

How can i determine which queries will contain a certain person in it's result set?

For example:

List<Integer> matchingQueries = magicMethod(queries, [23,45]); 

The list obtained by 'magicMethod' filters all sql queries present in the list 'queries' (defined above) and returns only those that contain either the person with id 23 OR a person with id 45.

Why i need it: I am dealing with an application that contains products and categories where the categories are sql queries that define which products belong to them (queries stored in a table also). Now i have a requirement where an admin has to see all categories an item belongs to immediately after the item was created. Btw, over 8.000 categories defined (so far, more to co开发者_如何学Cme).

language and db: java && postgreSQL

Thanks,

I can think of 2 ways. First way is to create a value object Query which contains two properties: a Long id query ID and a List<Person> results. Another way is to include the query ID in the results. E.g.

queries[0] = "SELECT id, name, etc, 0 AS query FROM person WHERE ...";
// ...
queries[8756] = "SELECT id, name, etc, 8756 AS query FROM person WHERE ...";

or

queries[0] = "SELECT id, name, etc, %d AS query FROM person WHERE ...";
// ...
queries[8756] = "SELECT id, name, etc, %d AS query FROM person WHERE ...";

for (int i = 0; i < queries.length; i++) {
    String sql = String.format(queries[i], i);
    // ...
}

so that you can re-obtain it by

int queryId = resultSet.getInt("query");

That said, this is all with all a bit a smell (DRY). I'd recommend to rethink the whole approach. Feel free to ask it as a new question, "I have functional requirement XYZ, I have approached it as follows. Is it right?".
