I meant in terms of potentially reducing the rowcount.Let's call a set from this table containing the same day, all of the intervals, and the same Event_Channel, a frame. One frame contains 96 rows, one row per interval. There are 9 event channels so there are 864 rows per date. Multiply 864 by the number of dates in the tickets table - 1366 - to yield the number of rows in the matrix table.
One possibility is to remove frames which don't have any corresponding rows in the tickets table.
Sorry,
I misunderstood you.
Then the best would be to work with a variable of the datetime type and set this variable to a fix date (for example 2013-03-01 YYYY-MM-DD format) or to set it to yesterdays date. And then retreive the frame for all 9 event channels.
Would that be better?
Greetz,
