Question

I’m writing a perl script that will access a MySQL database to determine whether or not a tool has passed or failed and I’m getting an error when I try to fetchrow_array on the code.

Basically what is happening is I’m looping through a list of tests to see if they have passed or failed so the loop looks like:

foreach my $test (@tests){
    $sth = $dbh_k->prepare("select fn_get_test_status(' $test ');");
    $sth->execute();

    my @data = $sth->fetchrow_array();
    print("$test\n");
    print("@data\n");

}

and that function returns either the string “passed” or “failed” however I can’t figure out how to pull just that one string out and incorporate it into my perl scrip.

I keep getting the error Use of uninitialized value in join or string at line xx.

Any tips or ideas? thank you

EDIT:
I may have an array of arrays that is being returned as my data type, how to I go into this to check it’s contents?

Here’s the solution we figured out in the chat:

my $sth = $dbh_k->prepare("select fn_get_test_status(?);");
foreach my $test (@tests){
    $sth->execute($test);

    my @data = $sth->fetchrow_array();
    printf "%s: %s\n", $test, @data;
}

Main problem were the spaces next to ' $test '.
