You could also use the IN operator:
SELECT (field list)
FROM MyTable

Lots of solutions! Have fun!

I had a similar situation. Simply convert your character variable to a dec character. Convert your Year/Month to a CYYMMDD format. Then convert to a date. I did this in a DB2 SQL stored procedure and called a sql UDF.

DECLARE PERIOD CHAR ( 4 );
DECLARE YRMTH DEC ( 4 ) ;

SET YRMTH = CAST ( PERIOD AS NUMERIC ( 4 , 0 ) ) ;
SET MTHBEG = ( YRMTH * 100 ) + 1000001 ;

CREATE FUNCTION PEGGYB.DEC2DATE (
DATEDEC DECIMAL(7, 0) )

RETURNS DATE

LANGUAGE SQL
.
.
.
BEGIN
/*This function converts a 7 digit date to a Date data type*/
/*ONLY WORKS FOR DATE >1939 &

(‘between’ will, in effect, pull data that is >= the minimum value and
