Dear Monks,

I recently encountered the following sort of problem: a SQL statement is assigned to a scalar variable as,

<code style="font-size:100%"> $SQLstring = qq{ select rtrim('$lastname',' ')LAST from SYS.DUAL }; </code>

which works okay unless the last name is something like O'Reilly. I believe that the SQL statement is okay if the lone apostrophe is doubled (but not a double quote). My solution then is this,

<code style="font-size:100%"> ($tmp = $lastname) =~ s/'/''/;
$SQLstring = qq{ select rtrim('$tmp',' ')LAST from SYS.DUAL }; </code>

It doesn't permanently change <code style="font-size:100%">$lastname</code>, and it leaves the original code relatively intact. It just doesn't seem like the best way to solve the problem though. Are there other ways to temporarily alter <code style="font-size:100%">$lastname</code>?
