Question

我正在尝试根据订单状态列中模式 SLD 和 SOLD 的检查来确定商品是否已售出或库存，否则它将是库存

此外，如果 * 或 BAM 出现在 orderstatus 列中，则 BAMyesorno 列将为 BAM

对于字段 soldorstockdate，如果它存在（格式 mm/dd/yyyy），则将输入来自 orderstatus 列的日期，否则将输入来自 orddate 的日期

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

我尝试了以下方法：

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

我似乎无法涵盖没有年份的短日期（Chimmin 条目为 5/13）

试试这个修改后的例子SQL，我相信它应该非常接近预期。尽管我在输出示例中也对空字符串日期（''）感到困惑。

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

也可以用这个 example dbfiddle 试试。
