in reply to Getting length of longest value in a column

Have the database do the work for you:
my $query = <<'SQL'; SELECT ticket_id, abstract, priority, maxlen_abstract FROM (SELECT MAX(LENGTH(abstract)) AS maxlen_abstract FROM t1) AS s1 CROSS JOIN t1; SQL

Pay special attention to what your definition of length should be. You may not be in an ASCII-world.

[james28909]: like all the subs calling get_data get_array get_ect, you could just use get_data. once you send the data to get_data, check if it is a hash or an array ect. and do functions for each, in one sub
[james28909]: that looks like it would be alot more work than just renaming the sub though lol
[Lady_Aleena]: james28909, did you even look at the subs?
[james28909]: yes
[Lady_Aleena]: And you see how the first two are vastly different than the third, right?
