when a row of a subset is lost/deleted/moved away from it, the whole subset will need to be reordered.This can be done similarily : SET @pos=0; UPDATE busstops SET pos = ( SELECT @pos := @pos 1 ) WHERE route = 1 ORDER BY pos ASCChris H (chansel0049) I experienced a weird issue converting from 4 to 5.So, I do it in one "magick" query ;)Here an example:"3" is a some value, from form or somethingupdate item set rate = case when round((rate 3)/2) You sometimes run into the problem that you want to replace a substring occuring in a column with a different string, without touching the rest of the string.

Sometimes you have a lot of processes that could be updating a column value in a table. ID=54321 Here's a workaround for the update/subquery/cant do self table "bug"Senario is, ID 8 has multiple records, only the last (highest) record needs to be changedupdate t1 set c1 = ' NO'where id='8'order by recno desc limit 1I would prefer update t1 set c1=' NO' WHERE ID=8 AND RECNO = (SELECT MAX(RECNO) FROM T1 WHERE ID=8)But that's not currently allowed If you want to update a table based on an aggregate function applied to another table, you can use a correlated subquery, for example: UPDATE table1 SET table1field = (SELECT MAX(table2.table2field) FROM table2 WHERE table1.table1field = table2.table2field)This can be helpful if you need to create a temporary table storing an ID (for, say, a person) and a "last date" and already have another table storing all dates (for example, all dates of that person's orders).

What I'm doing here is copying the information I need from the row where job_id=1 to the row where job_id=6, on the same table.

Adam Boyle's commment above was just what I was trying to do, update one table based on a relationship between that table and another.

order by recno desc limit 1You can also accomplish the same by the following query :update t1 , (select id ,max(recno) as recno from t1 where id=8 group by recno) ttset t1.c1 = ' NO'where tt.id=t1and t1.recno=tt.recno Comments are welcome.

The @value := col will always evaluate to true and will store the col value before the update in the @value variable.
