First of all it is essential to use strict and use warnings at the top of every program. It saves a huge amount of time by revealing simple mistakes, and would have alerted you to the fact that you put a string into array #abc and then use the scalar $abc in your SQL statement. I assume here that you intended to use $abc throughout.
Your error is because that's not what an INSERT statement looks like. You also need to escape and quote the string in $abc properly as it contains single quotes, so you must write
$dbh->do(sprintf 'INSERT INTO oui (oui) VALUES (%s)', $dbh->quote($abc))
But it is best to prepare the statement first and then execute it
my $insert = $dbh->prepare('INSERT INTO oui (oui) VALUES (?)');
and later
$insert->execute($abc);
Or perhaps you mean "UPDATE oui SET oui = ?"? But that will set the oui field to the same value on every row of the table.

If you need to insert array of values, first make sure you have values in array variable.
#vals = ('One', 'Two', 'Three');
Error is because INSERT query syntax is wrong, here is the INSERT syntax
INSERT INTO <table> (col1, col2) VALUES ('val1', 'val2)
Here is the snippet that should work for you
use DBI;
my #vals = ('One', 'Two', 'Three');
$dbh = DBI->connect('dbi:mysql:remotegenius;host=localhost', 'root', 'active123') or die "Connection Error: $DBI::errstr\n";
my $in = $dbh->prepare('INSERT INTO oui (oui) VALUES (?)');
foreach (#vals) {
$in->execute($_);
}
