Question

I am trying to determine if an item is sold or on stock based on checking of the pattern SLD and SOLD from orderstatus column otherwise it would be stock

Also if * or BAM is present in orderstatus column then BAMyesorno column would be BAM

For the field soldorstockdate the date from orderstatus column would be input if its present (of the format mm/dd/yyyy) otherwise the date from orddate would be input

orderstatus	orddate	comment	BAM-Yes or no	Soldorstockdate
*SLD 05/11/2022	5/1/2022	Sold	BAM	5/11/2022
*SOLD 05/15/2022	5/8/2022	Sold	BAM	5/15/2022
37141 SLD BAM	5/5/2022	Sold	BAM	5/5/2022
*STOCK 05/16/2022	5/3/2022	Stock	BAM	5/16/2022
1277489 STK#39298.32831	5/4/2022	Stock		5/4/2022
36888 SLD FLOREN ANGEL	5/6/2022	Sold		5/6/2022
11274848	5/5/2022	Stock		5/5/2022

I tried the below:

SELECT 
    *,
    CASE 
        WHEN INSTR('%SLD%', `ORDERSTATUS`) > 0 
            THEN 'Sold'
        WHEN INSTR('%SOLD%', `ORDERSTATUS`) > 0 
             
        ELSE'Stock' 
    END AS comment,
    CASE 
        WHEN INSTR('%[0-9]/[0-9]%', `ORDERSTATUS`) > 0 
             OR LOCATE('*', `ORDERSTATUS`) > 0 
             OR LOCATE('BAM', `ORDERSTATUS`) > 0
            THEN 'BAM' 
            ELSE'' 
    END AS BAMYN,
    CASE 
        WHEN INSTR('%[0-9]/[0-9]%', `ORDERSTATUS`) > 0 
            THEN CAST(SUBSTRING(`ORDERSTATUS`, LOCATE('/', `ORDERSTATUS`) - 2, 5)  AS DATE)
            ELSE `ORD_DATE` 
    END AS soldorstockdate 
FROM 
    table

Answer 1

I could not seem to cover the short date without a year (the Chimmin entry with 5/13)

Try this modified example SQL, I believe that it should be pretty close to what is expected. Though I also had confusion of empty string dates (with '' ) in the output example.

SELECT 
    *,
    CASE 
        WHEN REGEXP_LIKE(`ORDERSTATUS`, 'SLD|SOLD') > 0 
            THEN 'Sold'
        ELSE 'Stock' 
    END AS comment,
    CASE 
        WHEN REGEXP_INSTR(`ORDERSTATUS`, '[0-9]{1,2}/[0-9]{1,2}/[0-9]{2,4}') > 0 
             OR LOCATE('*', `ORDERSTATUS`) > 0 
             OR LOCATE('BAM', `ORDERSTATUS`) > 0
            THEN 'BAM' 
            ELSE '' 
    END AS BAMYN,
    CASE 
        WHEN REGEXP_LIKE(`ORDERSTATUS`, '[0-9]{1,2}/[0-9]{1,2}/[0-9]{2,4}') > 0 
            THEN DATE_FORMAT(
                     STR_TO_DATE(
                         REGEXP_SUBSTR(`ORDERSTATUS`, '[0-9]{1,2}/[0-9]{1,2}/[0-9]{2,4}'), 
                         IF(LENGTH(REGEXP_SUBSTR(`ORDERSTATUS`, '[0-9]{1,2}/[0-9]{1,2}/[0-9]{2,4}')) < 10, '%m/%d/%y', '%m/%d/%Y')
                     ),
                     '%Y-%m-%d'
                 )
            ELSE `ORDDATE` 
    END AS soldorstockdate
FROM 
    input

That can be also be tried with this example dbfiddle .

Feel free to ask any questions about the handling.
