Do you just want to replace current value in client column to NEW.
You can write a stored proc , with a cursor and loop through the cursor,
update each table.

The Update query of yours will do fine..
otherwise try using string functions [instr()] like

Dear Friends,
I have two tables: T1, T2.
T1 has 3 columns: playerid, gameid, score

I wish to update table T2 such that sum of T1.score of each player, gets
updated in T2.totalscore. It may be something like this:

If it's values you are updating you can use the replace() string
function to do something like this:
update table1 set field1=replace(field1,'the','an');
To demonstrate:
mysql select replace(the-object1,the,an);

If dbA.id has the format you have specified MySQL should be able to
silently convert the type from char to int, and you can work with dbA.id
as it is integer column.

mysql insert into ch set id='001234';

If you are trying to set the first 6 characters of your column to '11'

Break it down into two steps. Compute your new values by customerid, then
update your customer table with your computed data.
CREATE TEMPORARY TABLE tmpFirstTran
SELECT CustID, min(Datestamp) as mindate
from Transactions
group by CustID;
update Customer c INNER JOIN tmpFirstTran ft ON ft.CustID
Yeah I thought of that but was hoping not to have to use a temp table.
Thanks!

No, MySQL will indicate if anything in the row has changed. If you are
updating with the same data, than nothing changes and MySQL doesn't
waste the time to lock the table, write the data and update the
indexes. It's much more efficient this way.

The issue is that the code doesn't know (and doesn't care) if the data
is actually being changed, it's just accepting the posted form data,
compiling it, and updating the record. It uses the return value (number
of rows updated) to make sure there wasn't a problem updating the
record.
Have you tried this other way of making an inner join?
UPDATE products_categories AS pc INNER JOIN products AS p ON pc.prod_id =
p.id
SET pc.prod_sequential_id = p.id
But that does not seem right our you could say:
UPDATE products_categories AS pc
SET pc.prod_sequential_id = pc.prod_id

You can't have two tables in the UPDATE query, at least not in v3.x of

table2. I think the SUBSTRING_INDEX should be OK.
You may have to split your query into a series of queries. There is some
guidance in the MySQL manual.

Dear Amit,
update lotjobtemp set duedate = (select duedate from

In MySQL, you need 2 queries for this:
SELECT @var:=duedate FROM importparameters;
UPDATE lotjobtemp SET duedate = @var;
Most probably, you will want to use a WHERE clause for both statments.
