Hi,
I need to update a table along the lines of the following
update table set LastUpdate=now(), UpdateSource='Abc' Where Key1 = 'Def'
and Key2 = 'ghi'
I need to possible do anywhere from 2 to 20 of these. Would it be better
to call an update statement for each of these,
What exactly are "these"? Is 'Abc' constant for all rows, or does it
change for each Key1&Key2 value?
If so, then simply
WHERE (Key1=... AND Key2=...) OR (Key1=... AND Key2=...) OR... should
suffice
or even:
WHERE (Key1, Key2) IN (val1, val2),(val3,val4), ...
If 'Abc' changes per Key1&Key2 values, explore the CASE statement.
Best,

Hi,
'Abc' would stay the same, as well as 'Def', but 'ghi' will change. I'll
look into the where with the in operator, thanks.
