To the enlightened ones: Setting up a nice frontend for csv files I stumbled accross the following problem:
use DBI; my $dbh = DBI->connect("DBI:CSV:f_dir=/tmp"); $dbh->do("CREATE TABLE csvtable (id INTEGER, name CHAR(64))"); $dbh->do("insert into csvtable (id,name) values (1,'bi')"); $dbh->do("insert into csvtable (id,name) values (2,'ma')"); my $result = $dbh->selectall_arrayref("SELECT * FROM csvtable limit + ?,?", {}, 0, 1);
but the disdainful answer always is
SQL ERROR: Bad limit clause!
I even tried it with the newest, hottest SQL::Statement 1.15, but to no avail. Unnecessary to mention that it works fine when I embed the limit figures in the statement without placeholder...

Update Thanks for the eplanations and hints. I think I will dynamically generate the statement and carefully untaint the values used for limit and offset, as they come from a web form.
