Depends on the shell you are using:

(assuming elements separated by white spaces)

[zsh]

Code:
$ f_name="a.sql b.sql c.sql"
$ print ${#${(z)f_name}}    
3

[ksh93 & bash]

Code:
$ f_name_a=($f_name);printf "%d\n" "${#f_name_a[@]}"
3

If none of the above works:

Code:
$ (f_name="a.sql b.sql c.sql";set -- $f_name; printf "%d\n"  $#)
3
