Struct fields (1, 2, 3... 11, 12... 20, 21) sorting

If the values of the struct field are in the order of 1, 2, 3, 11, 12, 20, and 21, if we want to sort this field, it is generally written in this way.
SQL statement:

Select * From xs_jbxx order by jyjxsbm

But the results may not be satisfactory: 1, 11, 12, 2, 20, 21, 3, 4

The results we want are: 1, 2, 3... 11, 12... 20, 21, which can be written in SQL statements to achieve satisfactory results.
SQL statement:

Select * From xs_jbxx order by convert (INT, jyjxsbm)

Convert the sorting field to an integer and then sort it.
