one sure-fire way to check if the data exists in a table is to run a
SELECT query to select that data.
then check the recordcount of the select query - if it is 0 then no such
data exists; otherwise the data is already there.

that's because you are probably over-writing some variable you created
to hold the action with each subsequent action...
use an array or structure to hold all your action, append each new
action taken to this array/structure, then loop over it to display all
actions taken
Azadi Saryev
IIRC, blockFactor is only relevant on the Oracle drivers, and it refers
specifically to how Oracle expects to batch and return large recordsets. If
Oracle is allowed to spool out large recordsets without returning them in
blocks, it will often spin the DB server out of threads, which then

It is not strictly true. You can declare a cursor, do a move end, read
from the metadata how many records
if cf did not get the full dataset from the db, would it still be able

A cfquery tag can potentially contain any number of SQL commands which

Probably you can just assign the query to a session variable:
cfset session.myQuery = myQuery /
Then output the query:
cfoutput query=session.myQuery

You don't need to change the query itself into structures.
