Query using BETWEEN/AND operators

Question

Im trying to query in forms using BETWEEN/AND operators. The field is for dates (YYYY) is stored in the DB as varchar (4). My code compiles but returns nothing...Any ideas of whats wrong...
PROCEDURE YR_RANGE_SEARCH IS
BEGIN
IF :SEARCH.NRA_START IS NOT NULL
AND :SEARCH.NRA_END IS NOT NULL THEN
:Global.BUFFER_START := :SEARCH.NRA_STRT;
:Global.BUFFER_END := :SEARCH.NRA_END;
BEGIN
SET_BLOCK_PROPERTY('NRHR', ONETIME_WHERE, 'NRHR.YEAR = ''' || 'BETWEEN' || :Global.BUFFER_START || 'AND' || :Global.BUFFER_END ||'''');
GO_BLOCK('NRHR');
EXECUTE_QUERY;
END;
END IF;
END;

Answer 1

check spaces in quoted text. i noticed that in your original query you had no spaces anywhere which made your ONETIME_WHERE resulting in something like NRHR.YEAR='BETWEEN2005AND2007' (if :Global.BUFFER_START=2005 and :Global.BUFFER_END=2007). For sure that always resulted in NULL value returned by the query;
in my answer
SET_BLOCK_PROPERTY('NRHR', ONETIME_WHERE, 'NRHR.YEAR BETWEEN '|| :Global.BUFFER_START || ' AND ' || :Global.BUFFER_END);
there is a space after BETWEEN and space before and after AND. Be careful.
