I need to create a new table (table 2) with the data from an existing column of table 1:
Table 1:
id1 | item | type
=============
1 | item 1 | type B
2 | item 2 | type A
3 | item 3 | type A
4 | item 4 | type B
5 | item 5 | type C
Table 2:
id2 | type | count
===================
1 | type B | 2
2 | type A | 2
3 | type C | 1
id1 is not the same as id2
I've searched for answers and tried using: SET, UPDATE, INSERT JOIN with AS and FROM like some answers suggested but none of them works for me. How do I do it?
I used these keywords for my search: mysql create table with existing column, copy column from another table, insert column from another table, update column data from another table column...
