Bit stuck.
In an attempt to optimize some db queries.
I changed this (gets all events first then check if enabled, then gets
the trigger fields for that event etc):
----
DIM rResult, rResultTrig, rResultAction AS Result
rResult = Main.hDB.Exec("SELECT * FROM events")
IF rResult THEN
IF rResult.Count THEN
FOR EACH rResult
IF rResult!enabled THEN
IF rResult!trigger1 THEN
rResultTrig = Main.hDB.Exec("SELECT * FROM triggers WHERE id
= &1 ", rResult!trigger1)
IF rResultTrig THEN
IF rResultTrig!param1 =
...
NEXT
----
to this (gets selected events and triggers table/fields):
----
DIM rResult AS Result
rResult = Main.hDB.Exec("SELECT * FROM events, triggers WHERE
events.trigger1 = triggers.id AND triggers.type = 3 AND events.enabled
AND triggers.param1 = &1", iId)
IF rResult THEN
IF rResult.Count THEN
FOR EACH rResult
...
NEXT
----
In the sql query tool from database manager it returns exactly the
correct records/fields etc
But how can I get the fields from the triggers table from this resultset?
I cannot do something like rResult!triggers.id
Is this possible?
Thanks.
