The same result for different parameters

I have a strange situation. For different parameters I always get the same result

function test
{
  while getopts 'c:S:T:' opt ; do
    case "$opt" in
      c) STATEMENT=$OPTARG;;
      S) SCHEMA=$OPTARG;;
      T) TABLE=$OPTARG;;      
    esac
  done  
    echo "$STATEMENT, $SCHEMA, $TABLE"      
}

test -c CREATE -S schema1 -T tabela1
test -c TRUNCATE -S schema2 -T tabela2
test -c DROP -S schema3 -T tabela3

Result:

CREATE, schema1, tabela1
CREATE, schema1, tabela1
CREATE, schema1, tabela1

What is failed in my script?

In bash, you need to localize the $OPTIND variable.

function test () {
    local OPTIND

Otherwise it's global and the next call to getopts returns false (i.e. all arguments processed). Consider localizing the other variables, too, if they're not used outside of the function.

You can also just set it to zero.
