Hi,

How can I do a query on a record variable in a function.
I want to do a dirty fulltextsearch on a table and then choose the string which have a low levenshtein-distance.
I wanted to it like this, but it doesn't work:

v_query := 'SELECT col FROM table WHERE LENGTH(dede) BETWEEN x AND y AND plainto_tsquery(string') @@ vectors';
EXECUTE v_query INTO v_rec;
v_query :=   'SELECT levenshtein('string', v_rec.col) AS lev WHERE levenshtein('string', v_rec.col) < 10';
EXECUTE v_query INTO v_rec2;

Or is there an easier way to do that. Maybe just to do one query at once?

Hope someone can help me.
