    You can use REPLACE function as well.

    declare @str as table( val varchar(20))

    insert @str

    select '12-FLA-2-02'

    declare @update varchar(20)='11111'

    select * from @str

    update @str set val=replace(val,LEFT(val, CHARINDEX('-', val)-1) ,@update)

    select * from @str

    You can, but I wouldn't recommend it:

    declare @str as table( val varchar(20))

    insert @str select '12-FLA-2-02'

    insert @str select '12-FLA-2-12'

    declare @update varchar(20)='11111'

    select * from @str

    update @str set val=replace(val,LEFT(val, CHARINDEX('-', val)-1) ,@update)

    select * from @str
