When you use the replace command if the row does not exist it is inserted.
MySQL Reference Manual:
Section 14.1.6
REPLACE works exactly like INSERT, except that if an old record in the table
has the same value as a new record for a PRIMARY KEY or a UNIQUE index
before the new record is inserted

The problem is that Aleksandr wants to increment a counter, not set it
to some fixed value. How could you use REPLACE for that?

Hi,
To solve this you can use the REPLACE command.

Aleksandr V. Dyomin wrote:
$key='somekeyvalue';
dbquery("update sometable set count=count+1 where keyfield='$key'");
if(mysql_affected_rows()<1)
dbquery('insert into sometable set keyfield='$key', count=1');
Another possibility would be
INSERT IGNORE INTO sometable SET keyfield = '$key',
I have another technique for this kind of data merge that speeds things up
(a lot!) but it requires a third table to make it work
Please post the results of SHOW CREATE TABLE for both the source data
table and the destination data table and I will show you how it works.

Hi!

I use mysql in my PHP script(for calculating INs and OUTs from site).
And I meet some strange thing there.
Example goal: store statistics for clicks on some links.
I use next algorithm:
---
$key='somekeyvalue';
dbquery("update sometable set count=count+1 where keyf
