> Hi,
How can I use select ... for update to update limit to update what I
select??
somewhat like:
select url,id from mytable for update order by priority,id limit 5;
I want update the id in above return like:
update mytable set allocatedto='whatever' where id in above return set.
Could I do it in one stmt.
And what is class_name in following:
SELECT [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ] expression [ AS name ] [, ...] [ INTO [ TEMPORARY | TEMP ]
[TABLE ] new_table ] [ FROM table [ alias ] [, ...] ] [ WHERE condition ] [ GROUP BY column [, ...] ] [ HAVING
condition[, ...] ] [ { UNION [ ALL ] | INTERSECT | EXCEPT } select ] [ ORDER BY column [ ASC | DESC | USING
operator] [, ...] ] [ FOR UPDATE [ OF class_name [, ...] ] ] LIMIT { count | ALL } [ { OFFSET | , } start ]
can any one give me a example??
