Question

I have strings such as M1 M3 M4 M14 M30 M40 etc (really any int 2-3 digits after a letter)
When I do ” ORDER BY name ” this returns:

M1, M14, M3, M30, M4, M40

When I want:

M1, M3, M4, M14, M30, M40
Its treating the whole thing as a string but I want to treat it as string + int

Any ideas?

Answer 1

You could use SUBSTR and CAST AS UNSIGNED/SIGNED within ORDER BY:

SELECT * FROM table_name ORDER BY
    SUBSTR(col_name FROM 1 FOR 1),
    CAST(SUBSTR(col_name FROM 2) AS UNSIGNED)
