Hello - I'm new to Perl.
Trying to set up a loop to call a series of lines to submit to SQL I've already assigned $line1, $line2, $line3 etc with sql queries to run on the database.
The problem is perl doesn't seem to like $linename.$counter
my $line1 = "use pricedb;";
my $linename = "line";
my $dbh = DBI->connect("DBI:mysql:host=localhost;database=mysql","root
+","root");
# set up a loop to make submitting lines easier ;
for(my $counter = 1; $counter <=10; $counter ++)
{
my $concatline = $linename.$counter;
my $rowsaffected = $dbh ->do(${$concatline});
if ($rowsaffected && $rowsaffected == 0E0)
{
print "Operations ws successful but no rows were affecte
+d \n";
}
elsif($rowsaffected)
{
print "Operation was successful ($rowsaffected rows)\n";
}
else
{
print "Operation failed: $DBI::errstr\n";
}
}
$dbh -> disconnect;
Please advise how I get the loop to pull $line1, $line2 etc?
NB I'm very new to Perl so would appreciate v simple suggestions - my previous experience is SAS, Matlab and a little VBA..Thanks!!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
