You can use the LIMIT clause to break up a long DELETE into a series of shorter ones,
executed in a loop.
So, in pseudo-code:
Set delete_row_max = 1000 (or another appropriate value)
do
{
DELETE FROM outgoing
WHERE timestamp last_time
LIMIT delete_row_max;
row_count = no. of
$dbh =
DBI-connect(DBI:mysql:database=$database;host=$host,$user,$mysqlpassword,{'RaiseError'=1});
$update_number = UPDATE $table set total_clicked = total_clicked + 1;
$sth = $dbh-prepare($update_number);
if (!$sth) { die Error: . $dbh-errstr . \n; }
if (!$sth-execute) { die Error: .
SELECT f.language as From, t.language as To

SELECT LAST_INSERT_ID() will return the last auto_increment key written. This value
is connection-specific, so that inserts performed on other connections will not affect
it (in other words, you'll get the last key generated by user 1, regardless of what
user 2 does in the meantime).

If you are using the Mark Matthews JDBC driver (MM.MySQL), there's another way to get
the last insert id: instead of using a generic Statement object to execute the INSERT
command, use an org.gjt.mm.mysql.Statement object. After executing an INSERT, the
method getLastInsertID() will return
Use a join query, rather than separate single-table queries:

It looks to me as though the tracked.window=137 condition is suppressing output of
any available rows which do not have a target match in tracked - tracked.window

SQL Server will allow you to limit a SELECT to the first n rows, but not (to my
knowledge) to skip a number of rows before returning the desired rows.
The mechanism used is SET ROWCOUNT (6.5 and 7.0) or TOP (7.0). The difference is that
SET ROWCOUNT limits the output rows before applying an
What would really help would be to use multiple row inserts, i.e.
INSERT INTO speed1 VALUES (a,b,c),(d,e,f),(g,h,I),...
So, prepare a series of inserts, each with a few hundred (or even thousand) row value
sets.

The valid range for an 'int' data type (your "id" column) is -2147483648 to
2147483647. The value you are attempting to set (37647438380) is not within this
range.
