Question

I have this table:

+--------+------------+---------------------+------+
| id     | product_id | pa_value_name       | oesd |
+--------+------------+---------------------+------+
|      1 |     120972 |                     |    0 |
|      9 |      84147 | 1-2 business days   |    0 |
|   3255 |         12 | 1-3 business days   |    0 |
| 260220 |     124881 | 10-12 business days |    0 |
| 641906 |     147053 | 11-13 business days |    0 |
| 650680 |     139790 | 12-14 business days |    0 |
| 702408 |     112249 | 13-15 business days |    0 |
| 705013 |     223960 | 14-16 business days |    0 |
| 736335 |     124882 | 15-17 business days |    0 |
| 765595 |     106570 | 16-18 business days |    0 |
+--------+------------+---------------------+------+

and I want to update oesd field by getting the ‘to‘ date in *pa_value_name* field.

For example:

+--------+------------+---------------------+------+
| id     | product_id | pa_value_name       | oesd |
+--------+------------+---------------------+------+
|      9 |      84147 | 1-2 business days   |    2 |
+--------+------------+---------------------+------+

In row 2 (id=9): oesd must be 2 as it should get ‘2’ from “1-2 business days” value of *pa_value_name*.

Thanks!

Answer 1

This will update oesd and convert the value to a number

UPDATE the_table SET oesd = CONVERT(SUBSTRING(pa_value_name, LOCATE('-', pa_value_name)+1), decimal);
