using sql to arrange a column with numbers and not letters -


how write sql statement arrange column

columna ------- 10a 11c 12v 10d 8f 8r 9c

so returns resultset in order

columna ------- 8f 8r 9c 10a 10d 11c 12v

(in numerical alphabetical order)?

i have tried statement:

select columna tblstudents order columna

but hasn't worked.

you have split strings numerical part , textual part, , convert numerical part actual number.

i don't know dialect of sql using; microsoft sql server:

select columna tblstudents order   convert(int, substring(columna, 1, patindex('%[^0-9]%') - 1)),   substring(columna, patindex('%[^0-9]%'), 1000)

the patindex('%[^0-9]%') find first non-digit in string, first substring gets characters that point, , second substring gets characters point end of string.
