Question

I have created a Stored Procedure, that looks like this:

DELIMITER €€
CREATE PROCEDURE `GetAllNonprocessedSMSes`()
   BEGIN
      DECLARE smsid INT(10);
      DECLARE finish BOOLEAN;

      DECLARE id_cur CURSOR FOR
         SELECT id FROM (
            SELECT
               MIN(id) as id,
               MIN(UDH) as udh,
               MIN(LENGTH(TextDecoded)) as txtlen,
               MAX(ReceivingDateTime)-DATE_ADD(MIN(ReceivingDateTime), INTERVAL 3 MINUTE) AS rcvtimeout
            FROM inbox
            WHERE
               Processed='false'
            GROUP BY
               IF(UDH='',id,SUBSTR(UDH,1,10))
            HAVING
               rcvtimeout>0
               OR udh=''
               OR txtlen<156
         ) AS baseview
         ORDER BY id;

      DECLARE CONTINUE HANDLER FOR NOT FOUND SET finish = TRUE;
      OPEN id_cur;

      the_loop : LOOP
         FETCH id_cur INTO smsid;
         CALL GetSMS(smsid);

         IF finish THEN
            CLOSE id_cur;
            LEAVE the_loop;
     END IF;
      END LOOP the_loop;
   END €€
DELIMITER ;

I know the cursor selects more than one row, but when I call the Procedure it only returns one entry, but when it is runned it only returns the first entry.
How can I fix that?

EDIT
The GetSMS Stored Procedure looks like

CREATE PROCEDURE `GetSMS`(IN smsid int(10))
   BEGIN
      DECLARE smsudh TEXT;
      SELECT `UDH` INTO smsudh FROM `inbox` WHERE `ID`=smsid;
      IF (STRCMP(smsudh, '') < 1) THEN
         SELECT * FROM `inbox` WHERE `ID`=smsid;
      ELSE
         SELECT * FROM `inbox` WHERE `UDH` LIKE CONCAT(LEFT(smsudh, (LENGTH(smsudh)-2)), "%") GROUP BY `ID` ORDER BY `UDH`;
      END IF;
   END €€
DELIMITER ;

Can you then figure out if there are any ways to create the GetSMS
Procedure as one SELECT-statement, so I can create it like INSERT INTO
tmptable SELECT … – The87Boy 3 mins ago

# put into PROCEDURE GetAllNonprocessedSMSes

DROP TABLE IF EXISTS TempTable;
CREATE TABLE TempTable LIKE `inbox`; 

# then, in GetSMS

  IF (STRCMP(smsudh, '') < 1) THEN
     INSERT INTO TempTable SELECT * FROM `inbox` WHERE `ID`=smsid;
  ELSE
     INSERT INTO TempTable SELECT * FROM `inbox` WHERE `UDH` LIKE CONCAT(LEFT(smsudh, (LENGTH(smsudh)-2)), "%") GROUP BY `ID` ORDER BY `UDH`;
  END IF;

You might want to put a lock around TempTable so that you don’t run two copies of the procedure concurrently.
