Question

I Defined the following procedure which compiles correctly.

http://pastebin.com/pBHFctHq

When i call that procedure it returns an error:

ERROR 1292 (22007): Incorrect date value: ''2012-12-30'' for column 'date_part' at row 11

I think the problem is fetching the date from the cursor, how would i solve it??

small description of the code: i am looping through different tables , and gathering information on each partition that may exist in the table (each table is range partitioned by date)

Answer 1

I think you are comparing string with date that’s why you are getting error..
you can use this for comparision:

           TO_DATE(PARTITION_DESCRIPTION,'YYYY-MM-DD')      // in oracle this will work

           STR_TO_DATE(PARTITION_DESCRIPTION, '%Y-%m-%d')   // in mysql this will work

           convert(varchar(20),PARTITION_DESCRIPTION,104)   // in ms-sql this will work

so your code look like this:

   BLOCK2: BEGIN
                            DECLARE loop1_eof INT DEFAULT FALSE;

                            DECLARE cur1 CURSOR FOR SELECT TO_DATE(PARTITION_DESCRIPTION,'YYYY-MM-DD')
                            FROM INFORMATION_SCHEMA.PARTITIONS
                            WHERE TABLE_NAME=tmp_title AND TABLE_SCHEMA='test1';    
                            DECLARE CONTINUE HANDLER FOR NOT FOUND SET loop1_eof = TRUE;

                            OPEN cur1;
                            loop1: LOOP
                                    FETCH cur1 INTO date_part;
                                    SELECT max(id) from `test1`.tmp_title where CurrentDate < date_part;
                                    IF loop1_eof THEN
                                            CLOSE cur1;
                                            LEAVE loop1;
                                    END IF;
                            END LOOP loop1;
                    END BLOCK2;
