Question

dear all..i have this data inside DB:

line     model        serial      
fa01     kd-g335ud   105x0001     
fa01     kd-g335ud   105x0002     
fa01     kd-g335ud   105x0003 //up to 20pcs or regardless of the number of goods in the db
fa02     kd-r311ed   105x0001
fa02     kd-r311ed   105x0002 //up to 20pcs or regardless of the number of goods in the db

fa01    kd-g335ud    20
fa02    kd-r311ed    20

please help, thanks before 🙂

Answer 1

SELECT line, model, count(serial) as qty FROM table_name GROUP BY line, model

Not 100% sure on my query, but that is along the lines of what you want. Hopefully that query is correct!
