列仓库名称未修复。那么我如何创建如下的数据透视表
+-------------------------------------------+----------------+--------+----------------+-------------+
| item | Main Warehouse | NADEEM | total quantity | total value |
+-------------------------------------------+----------------+--------+----------------+-------------+
| Alcatel 1054D 1054E BLACK CHARCOAL GREY | 0 | 1 | 1 | 500 |
+-------------------------------------------+----------------+--------+----------------+-------------+
| Alcatel 1054D 1054E BLACK+PURE WHITE | 0 | 1 | 1 | 1500 |
+-------------------------------------------+----------------+--------+----------------+-------------+
| Alcatel 2008D WHITE+METAL SILVER DUAL SIM | 1 | 0 | 1 | 45643 |
+-------------------------------------------+----------------+--------+----------------+-------------+
| Alcatel 2008D-BLACK METAL SILVER DUAL SIM | 1 | 0 | 1 | 4544 |
+-------------------------------------------+----------------+--------+----------------+-------------+
答案 0 :(得分：0)
这是一种方法，假设您要从仓库字段中解析所需信息：
SELECT item_code,
IF(LOCATE('Main Warehouse', warehouse), 1, 0) AS `Main Warehouse`,
IF(LOCATE('NADEEM', warehouse), 1, 0) AS `NADEEM`,
COUNT(item_code) AS total_quantity
FROM some_table
GROUP BY item_code
